Problems with 2005 Nissan Pathfinder ENGINE AND ENGINE COOLING

I am filing this complaint since nissan does not do anything with the problem to be fixed, i have a 2005 nissan pathfinder, when were on the road our car is having trouble shifting starts jerking, and were so scared that will not make it home because the way its acting we finally made it home and the ca would not reverse we look online and search what' causing the problem and read a bunch of complaint with the consumer at automotive.com stating that the reason for the problem is the radiator fluid leaked into the transmission that causing the transmission to burn, called around with a bunch of auto mechanic and when i mention that i need my transmission replace the mechanic immediately said you know you need your radiator replace because that is causing your transmission problem i filed a complaint with nissan and denied the complaint this should be in the recall because this is dangerous if you weren't aware of the problem if your on the road hope you can help us with this problem. *tr

Radiator leaks into transmission causing transmission to mess up. nissan is aware of the issue and told me it happens on higher mileage pathfinder but they only extended the warranty to 80,000 miles. i researched the 2005 nissan pathfinder and found that this is an ongoing problem that occurs with this year and model. i feel there should be a recall on this problem and nissan should be held accountable. *tr

Radiator coolant and transmission fluid mixing, causing major problems with vehicle. hesitant shifting, or worse, no shifting or movement at all. especially dangerous on highway (interstate). *tr

Around 95000 miles the transmission began very abrupt jerking when accelerating. around may 2011 transmission began slipping, i googled the problem and discovered many people had the same problem due to radiator cracked. i looked into my radiator and discovered strawberry looking fluid . replaced my radiator , an flushed it a few times and then flushed my transmission which had the same color fluids, i believe nissan was aware of these faulty radiators and transmission and drag it out through court so people would loose their opportunity to use their warranty. i am currently trying to get nissan to replace my faulty transmission and i am willing to pay a $3000.00 fee but so far they are reluctant. any suggestions you may have would be appreciated. *tr

I own a 2005 nissan pathfinder. nissan extended their warranties on the 2005 pathfinders to 80,000. the reason they did this is because they know their defective radiators have been causing transmissions to go out due to contamination from the radiator fluid. since i was deployed, i was unaware of the extension or the problem until my transmission started giving me problems in may of 2011. the other day, i tried to pull out of a gas station and i lost all acceleration due to the transmission slipping almost causing a serious accident. i have a nissan complaint ticket but unless it is forced into recall, i will have to pay for my new transmission on a car i just recently paid off. as a consumer, i should not have to pay for someone else's design defect that causes major mechanical cost and safety issues. after doing some research, most customers are being told to come and have the transmission flushed for approx. 500$ to be told the transmission needs replacement. this defect needs to be addressed immediately before someone dies as a result of nissans negligence in standing behind their product. *tr

2005 nissan pathfinder internal radiator leak causing the transmission to fail started with strong vibration between 40-45 mph. dealer inspection states internal rupture of the oil cooler contaminating the oil in the transmission. *tr

Tl* the contact owns a 2005 nissan pathfinder. the contact stated that while driving, the vehicle started shaking violently. the vehicle was taken to the dealer who diagnosed that the radiator was leaking coolant in the transmission, which caused it to be defective and needed to be replaced. the manufacturer was not made aware of the failure. the vin was not available and the vehicle was not repaired. the failure and current mileage was 61,000.

Tl* the contact owns a 2005 nissan pathfinder. the contact stated that she received a recall letter for nhtsa campaign id number: 10v517000 (engine and engine cooling) and the vehicle was taken to the dealer for the repairs. the dealer discovered that the catalytic converter was defective and would need to be replaced. the manufacturer was contacted who stated that the catalytic converter was probably affected by an ecm failure but they would not pay for the repairs, only the component listed under the recall. the contact believed that the manufacturer should be held responsible for the repairs since they were was directly related to the failure as described in the recall. the vehicle was not repaired. the failure and current mileage was 120,000.

My 2005 nissan pathfinder bucks as i accelerate. i took my car to lithia nissan and they informed me that there was a defect with the transmission and radiator, and that they saw milky fluid in my car which indicated transmission and radiator fluid mixing together. the cost would be $5000 to fix both. the next day i took it to my personal mechanic, and he checked the fluid which was clear. the bucking problem still exists in my car, what else would cause this problem. the dealer said i was out of the warranty stage so i would have to pay for the repair, i don't trust them now because they told me false information regarding the color of the fluid. what should i do ? *tr

Tl* the contact owns a 2005 nissan pathfinder. the contact stated the radiator and transmission fluids were mixing together abnormally and causing the vehicle to stall. in addition, the vehicle would not change gears as a result of the failure. the vehicle was taken to the dealer who advised the contact to replace the transmission and radiator. there were no recalls for the failure. the manufacturer was contacted who advised that they will give her a return call within a few days. the vehicle was not repaired. the failure mileage was 102,000.

Nissan manufactured the 2005 nissan pathfinder with a faulty radiator that leaks radiator fluid into the transmission causing the irreparable damage to the transmission. the car experiences vibration (which has loosened bolts & other parts on the undercarriage) along with shifting problems & hesitation when accelerating. nissan extended the warranty to 8 years, 80,000 miles but the problem usual occurs at high mileage. my car has 104,000 miles & they will not cover the cost of replacing the radiator (or transmission). i only received a letter from nissan a few months ago stating there may be a radiator leakage problem but did not advise of the problem with leaking into the transmission nor did it state symptoms to watch for. i have been experiencing symptoms but did not know it was related to this issue until i went online and found several complaints by other pathfinder owners. i bought my car to the dealer and they advised that it was a different issue and then an hour later they advised it was the radiator issue. since i am over the 80,000 miles, they will not pay for replacement. i have contacted the corporate office and was told i would hear from them in approximately 24-36 hours but that was 5 days ago. *tr

2005 nissan pathfinder se with 86,000 miles starting having operational issues when running at 2000 rpm's. was taken to the dealer for numerous services and was mentioned to service department. service department said they could not find anything and that it wasn't anything to worry about. after several thousand miles the rough engine running at 2000 rpm's was becoming more evident. service manager test drove the vehicle and immediately knew what the problem was as they had many other pathfinders in for the same problem. we were told that the radiator seal was leaking fluid in the transmission and that the radiator needed to be replaced as well as a transmission flush to the tune of $850.00. nissan representative appeared at dealership and was notified of the problem however refused to cover the problem saying that it was our problem because it exceeded the 80000 mile extension on the radiator. nissan never notified us about and extension on the radiator in the first place. the service manager also indicated that he could not put a warranty on the transmission that received the radiator fluid in the transmission. nissan has known about this problem but refuses to own it. they have lost a very good customer who was about to purchase another nissan vehicle. *tr

Premature wear of timing chain and timing chain guides. in the nissan pathfinder 4.0l v6 engines, the timing chain and timing chain guides are wearing out prematurely. our vehicle was identified by nissan dealer service at 62,000 miles and the required fix action was to replace the timing chain and timing chain quides out of warranty at a cost of $1500.00. these parts do not have a recommended service interval as they are supposed to last the life of the vehicle however nissan has identified this as a problem in the pathfinder and other nissan vehicles that use the same engine and has issued two separate service bulletins to correct the problem at customer expense. this appears to be an engineering deficiency and should be addressed by nissan at their expense. *tr

I own a 2005 nissan pathfinder se, 4.0 liter v6 with 53,000 miles. i just had to replace the timing chains, timing chain guides, and timing chain tensioners. i was driving on the freeway when the problem occurred and had to have the car towed home. the dealer wanted in excess of $2,500.00, i had the work completed for $1,800.00 with another source. i have come to find out that this is not an uncommon problem with this vehicle and nissan refused to do anything about it. i contacted nissan north america and was told that while my car has under the 60,000 mile warranty limit, i was over the 5 year limit by 7 months. *tr

This vehicle is a 2005 nissan pathfinder se, 4.0 liter v6 with 53,000 miles. 60 month warranty expired 7-2010. the timing chain and gears broke apart causing engine to stop running. normally timing chains and gears should not disintegrate for considerably longer than 53,000 miles. filed complaint with nissan north america 3-28-11 with no satisfaction. they were unwilling to do anything since the vehicle is past 60 month period and since we never serviced the vehicle at a nissan dealership. having researched this problem it appears that this is not an uncommon complaint with 2005 and 2006 4.0 liter v6 motors. dealer is asking in excess of $2000.00 to correct the problem. *tr

This was a sudden failure of the catalytic converters on a mountain road resulting in loss of power. *tr

Radiator cracked and leaked into transmission which lead to transmision failure

Tl*the contact owns a 2005 nissan pathfinder. the contact stated the radiator cracked causing fluid to leak into the transmission. the contact took the vehicle to the dealer for diagnostic testing. the dealer stated the radiator and the transmission needed to be replaced. the contact took the vehicle to a local mechanic who replace the transmission and radiator. after the repairs, the contact noticed that the engine began to malfunction. the contact did not take the vehicle back to the dealer for a diagnostic test. the failure mileage was 107,000.

Tl*the contact owns a 2005 nissan pathfinder. the contact stated that the radiator fluid leaked onto the transmission which caused the vehicle to vibrate when traveling between 40-45 mph. the vehicle was taken to an authorized dealer who stated that the radiator was cracked. the vehicle was being repaired. the current and failure mileages were 109,000.

I received a letter from nissan informing me that the warranty on the radiator assembly of my 2005 pathfinder is being extended because 'a crack in the radiator assembly might occur at higher mileages leading to internal leakage of engine coolant'. after doing some research it was evident that because the failure is internal the only way to detect it is by a malfunctioning transmission due to the intermingling of fluids. i contacted nissan and asked them if the radiator failure caused the transmission to malfunction would the extended warranty cover repair or replacement of the transmission. they stated that if the dealer's work order stated that the transmission (or any other part) was damaged due to the radiator failure it would be covered. i then asked why they don't recall the radiator so that they only have to replace the radiator and not the transmission in addition to the radiator. nissan stated that the government did not deem this a safety issue therefore they were not required to issue a recall. wouldn't it make good business and public relations sense for nissan to stand up and do the right thing and issue a voluntary recall? so my question to the government is; why isn't an unexpected transmission failure of a moving vehicle a safety issue? any product defect that causes the sudden loss of power to a moving vehicle is a safety hazard. there are numerous other product recalls due to sudden loss of power, what is different about this one? *tr

I own a 2005 nissan pathfinder and have been doing all the required maintenance on it in a very timely manner. it is a very well maintained suv and had only 49,997 miles on it. i got a safety recall notice on it for the ecm relay issued and took it to the dealer. i was also experiencing some whining noises. the service dealer advisor at the dealership told me that my timing chains had a problem and needed to be replaced. he said this was a serious issue and could lead to engine damage and is a potential road hazard. he also said it needed to be fixed immediately, as this was a known problem, that had been experienced by a number of other customers and that nissan motor co. had issued a service bulletin ntb09-128 regarding this problem. i am really surprised that nissan did not think it was necessary to communicate this piece of important information to all its customers. my son who is 21 years old drives this suv on ski trips and i am really alarmed that this defect which was known to nissan could have lead to some serious road hazards. nissan has acted in a very callous manner because they did not inform their customers about the possibility of such a serious issue which can lead to road hazards. they did not issue a safety recall to fix the issue. i request you to kindly investigate this issue and ensure that nissan communicates this serious flaw to all owners of 2006 nissan pathfinders and any other model which has the same issue. updated 03/07/11 *bf

Timing chain and fuel sending unit on 2005 pathfinder is defective. while the manufacturer recognizes this as an ongoing problem, they are only willing to cover those vehicles up to 72,000 miles. a claim was filed and rejected on both problems as my vehicle has 82,000 miles. *tr

My 2005 nissan/pathfinder was leased from ray brandt nissan in july 2005. in april 2009 i purchased the lease. in january 2011 i began to have problems with the vehicle. it was determined that the issues were related to the transmission and radiator. the technician [xxx]at [xxx] referred me to the national consumers dept. of nissan because this was an issue they were aware of but, had not notified the consumer. the representative [xxx] ( 800-647-7261 ext 47116) at the national division / nissan usa., acknowledged the default and therefore they replaced the transmission and radiator. this they considered was a "good will' measure because the vehicle was out of warranty by 200 miles. i drove the vehicle for 5 days and the same issues arose again. i brought the vehicle back to ray brandt.this time they informed me that the issues were related to the catalytic converter. apparently it had come apart and damaged the engine. the dealership, ray brandt again informed me that this was also a defect by nissan and referred me back to the national consumers' division, nissan usa. i contacted [xxx] again. this time she informed me that it was nissan' policy to extended only 1 good will measure. they refused any assistance. while awaiting for her response and the vehicle still in the shop at ray brandt, a re-call was issued on the engine. [xxx] and nissan still contend that they only extend 1 "good-will" measure. both nissan usa and ray brandt nissan acknowledge the defaults and faulty parts however, neither are willing to assist. in addition i have considered purchasing another vehicle from ray brandt but they have refused to offer a appraisal value for a trade-in. prior to these issues i had never experienced any problems with my pathfinder until nissans' defective parts malfunctioned.i am appealing to you for your assistance in rectifying these issues. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

I have a 2005 nissan pathfinder 4x4 se off road with 115,000 miles . beautiful vehicle but beginning to have problems the fuel gauge will go to empty when full , also having hesitation about 40 miles an hour .i read about the horror story with radiator problem causing transmission problem . i have an appointment at a nissan dealer this weekend for the recall on the ecm so i will have further info on the hesitation , nissan recalled the fuel gauge problem but limited to 72,000 miles vehicle only ,i think they should up hold the nissan rep and take care of these problems also the transmission problems due to faulty parts . these problems are not normal wear and tear . *tr

I received, in the mail, a warranty notification from nissan north america headquarters, consumer affairs department, franklin, tn. basically, it reads: nissan has extended your vehicle's new vehicle limited warranty as it applies to the radiator assembly to 96 months/80,000 miles (whichever comes first)...nissan north america wbi/10-029. when my husband, scott, contacted our local nissan dealerships service department, he was informed that the component would have to fail before they could do anything about it. according to other nhtsa complaints from nissan pathfinder owners who have had the component fail, it sometimes causes transmission failure and loss of vehicle control (lack of engine power throughput to provide mobility). if the component were to fail it seems that it would create a safety issue under some conditions (on highways where it is not convenient to pull over). some pathfinder owners have claimed that it can cost thousands of dollars to replace the transmission, and that nissan sometimes does not cover repairs beyond the radiator, despite that problem can leak coolant into the transmission, sometimes causing serious damage to, or failure of the transmission. nissan should know about this problem and offer owners of possibly effected vehicles a free test to determine if their vehicle does, indeed have a defective radiator assembly. if a test is not available, then the radiator assemblies on these vehicles should be repaired of replaces as necessary to ensure that they will not fail under normal conditions and mileage. furthermore, if a radiator assembler were to cause a transmission to need repair or replacement, nissan should cover associated transmission correction costs. because of this problem, we (my husband and i) no longer driver our pathfinder on long trips, and have lost faith in our vehicle and nissan.

Tl* the contact owns a 2005 nissan pathfinder. the vehicle was taken to the dealer for repairs when they informed the contact that the radiator was leaking and needed to be replaced. the dealer replaced the radiator. the manufacturer filed a complaint and the contact was awaiting a response. the current mileage was 91,692 and the failure mileage was 90,586.

2005 nissan pathfinder has reportedly had multiple complaints regarding the cooling system leaking into the transmission, causing rust and subsequently, a failure in the transmission. it is reported that the radiator and transmission can be replaced to the tune of $5000-$8000 but does not fix the problem - will have to be done again in the future. transmission slips between 40-60 miles per hour and loses acceleration. dangerous behavior that can cause serious accidents and injury. nissan is ignoring the problem and won't respond to complaints. have extended warranty to 80,000 miles but of course the majority of owners experience this issue at 100,000 miles or 5-6 years. *ln

We had to replace the ipdm in november 2010, the truck stopped running in middle of the road, we had 118,000 miles on vehicle. in july 2011, we were on vacation in indiana and on our way to see family in ohio. we were on the interstate and the vehicle would not excellerate over 40 - 45 mph., we stopped at an autozone to test the vehicle to see what the problem was and it cleared it. since that time, the engine light would periodically come on. on september 15, 2011, the truck would not start. the truck is still at the mechanic to be repaired, we were advised the problem is the radiator leaking into the transmission causing transmission to fail. cost is $6,000 to repair and truck has 127,000 miles on it. this is a consistant complaint of owners of this vehicle, however, nissan does not want to do anything to correct the problem. this is my first and last nissan. *tr

My 2005 nissan pathfinder started stalling last week. i would be driving on the highway and it would just go dead making it near impossible to turn the steering wheel. i was towed to the nissan dealership whom informed me it was an ipdm issue which was in the process of a recall.i informed them i was strapped for money being it was a 700 dollar job. they said chances were it would be covered. it was not covered! i was informed by their consumer affair people if there was infact a recall i may be notified for reimbursement. i have found on numerous sites that it is recalled but because i did not receive a letter it is not their problem. this is not the first issue i've had with nissan. a fuel sensor issue was found and they covered nothing telling me it was not a safety issue. i was out of warranty so tough luck. another 377.00 bucks. please investigate nissans practices. i will never trust the nissan name again. *tr

Vehicle shuts off while driving and has faulty fuel gage and sending unit

Tl* the contact owns a 2005 nissan pathfinder. the contact stated that the vehicle would intermittently stall without warning when driving 35 mph and above. the vehicle was taken to the dealer who informed her that the ecm relay switch was failing. the contact stated that the ecm was previously replaced for the failure. the manufacturer and advised that they would return her call within the next twenty four hours. the failure mileage was 88,000.

Tl*the contact owns a 2005 nissan pathfinder. the contact stated that while driving 40 mph, the vehicle suddenly stalled; there was no power steering or power brakes. the contact was able to drive home and to avoid a crash. the vehicle was taken to an authorized dealer where the contact was informed that the ignition power distribution module needed to be replaced. the contact referenced recall 10v517000 (engine and engine cooling) and was told that the recall did not take effect until december 2010. the failure mileage was approximately 77,000.

I brought car to the dealer for service and asked for the tranny to flushed they said the radiator had a leak and there was coolant in the transmission. they offered to replace the radiator and flush the system for $1,000 but didn't think that would help. the dealer wanted to replace the transmission and radiator for 8-10k. i ended up taking a loss and trading in the car couldn't see putting that kind of money into a 5 year old car. after looking on the internet found hundreds of people having the same issue very disappointing nissan doesn't stand behind their product. *tr

We were driving in our 2005 pathfinder when the car decided to decrease speed all by itself after we pulled out into an intersection with traffic headed our way. took the car to nissan dealership was told coolant leaking into transmission due to a defected seal in the radiator to fix the problem ecm,tcm, transmission and radiator need to be replaced about 7,000 to fix the problem nissan need to correct there mistakes not recall one component that got fried because coolant leaked on it that's not going to correct the problem. i cant believe we have to wait for someone to loose a love one before action is done we were second away from that, seriously. not a joke nissan needs to stand up for there mistake this is america right don't we have rights to a safe auto for our children after paying alot for a car that suppose to be safe just google 2005 pathfinder complaints and see how many are really out there 93% transmission problem on the 2005 same thing coolant leaking into the transmission make nissan recall these cars and fix the problem we work hard for our country and deserve quality what if this was your family nissan you have your family in one of these car think not!!! *tr

Bought a nissan pathfinder se 2005... it has over 70,000 miles on it now. i was driving it down the highway, with my husband and 12 month old baby girl, surrounded in wall to wall rush hour traffic and road construction. the nissan started making a grinding noise then started slipping 4th gear. suddenly without any notice 4th gear was completely out. i had to stop the car, put it in 3rd gear manually and drive before getting rear ended. miraculously it drove in 3rd gear so we took it to the nissan dealership who explained to us that the problem with the radiator. the radiator was causing coolant to leak into the transmission, mixing with the transmission oil and destroying our transmission. he knew this problem well since he's fixed them many times. we checked on the internet and found countless more individual such as ourselves experiencing the same problem. the mechanic also explained the new pathfinders are not using these faulty radiators, so nissan knows there is a problem. to fix the transmission using a used one will be $4,000. that's including the used transmission, labor, shipping costs, tax, and fluids. i understand that things break and wear out, but if a company says that you should buy there vehicle because they will stand behind it, and that they believe that they have a quality product that you can count on, then they should do as they say and stand behind there nissan. we are one car short with not much money to pay for such a expensive repair. a recall is the right thing to do, i don't think someone has to die before someone somewhere stands up to make something happens. our family have already suffered a loss due to a suv malfunction. at least toyota admits their faults and takes care of the problems. nissan have lost all credibility with our side of the family and friends. *tr

I have a 2005 nissan pathfinder and on tuesday on my way to work the truck stop on me in the middle of freeway. according to nissan there are no recalls on my vehicle but i received a letter for recall from them that i cant find. a gentleman help me get it to the side of the free way since there was a lot of traffic. and it die again. all the lights on the dashboard were blinking like crazy. the truck went back on and did it again on my way home barely got home and did not want to turn on again. had to take it to the agency and they told me it was the ibpm control module. which controls everything. so i been calling nissan and they don't have any recalls according to them, but what about if it would of caused an accident. i felt my life was in danger. *tr

Tl* the contact owns a 2005 nissan pathfinder. while driving up an incline approximately 25 mph, the transmission began to slip with extreme hesitation and the rpms increased rapidly. the failure occurred whenever the vehicle was in operation. the vehicle was taken to an authorized however the vehicle was not diagnosed or repaired. the contact stated there was a crack in the radiator which caused damage to the transmission. the manufacturer was not notified of the problem. the approximate failure mileage was 75,000.

I own a 2005 nissan pathfinder and i have radiator and transmission failure! defective radiator causes engine coolant to leak into transmission which could fail at any time. driving at highway speed could and will cause dangerous situations. i must not be alone in this problem either, there are hundreds of complaints on this sight regarding this very issue! nissan needs to take responsibility for their design/manufacturing flaw. many consumers who are not aware of this are at danger and other people on the road as well. nissan needs to recall this immediately!!! why does someone have to be killed or injured seriously before nhtsa or nissan gets involved. i guess money is the root of all evil! and nissan is more concerned about their profits than someone's life! we as consumers need to do something about this! this has nothing to do with the wear and tear on our part, but nissan design department! *tr

2005 nissan radiator and transmission failure. defective radiator causes engine coolant to leak into transmission which may fail at any time. driving at highway speed, entering traffic, merging or entering intersections causing dangerous conditions as the vehicle fails to move, decelerates quickly or the transmission slips badly and fails to accelerate. hundreds of incidents of failures are reported on the internet. an apparent design/manufacturing flaw in the radiator causes the condition. nissan has taken no responsibility or corrective action. thousands of unsuspecting consumers and their families are at risk each day driving or riding in these vehicles. consumers are left paying thousands of dollars for replacements. *tr

The initial problem was that the vehicle overheated. further investigation revealed that the transmission cooler inside the radiator had broken. this flooded the coolant system with transmission fluid, which then circulated through the engine. the coolant/water mix also leaked into the transmission and caused the transmission to fail. corrective action taken - replace radiator, all hoses, and transmission. *tr

When our 2005 nissan pathfinder started to make a grinding noise during gear shift at 40 mph and 60 mph, we immediately took it to the nissan dealership only to be told that a problem with the radiator was causing coolant to leak into the transmission, mixing with the transmission oil and destroying our transmission. this was on august 12, 2010. we were told we would have to replace the entire radiator and transmission at a cost of over $4500.00. we could not understand how coolant could be leaking into the transmission, so we immediately contacted nissan north america and filed a complaint. this kind of damage should not occur due to normal wear and tear. we were informed that not enough complaints had been filed but they would keep a record of our call and we would be contacted if they ever did a recall in the future. still confused about what was causing this problem, we decided to get a second opinion at another nissan dealership, less than 15 miles away from the first. this was done on august 30, 2010. we were told the same thing, the coolant was leaking into the transmission, but they wanted over five thousand for the same repair. before making a final decision, we decided to research this issue further. we were amazed to find over a hundred complaints online, all from owners of 2005 nissan pathfinders, and all complaining about the thousands of dollars they had to pay to repair both radiator and transmission for the same problem we, too, were experiencing. with no help or acknowledge from nissan, we went to an outside mechanic and had the work done at a much lower cost. *tr

My 2005 nissan pathfinder began to shutter then jerk back into normal driving as it reached speeds of 60-70 mph. it was very sporadic in the beginning, but started to happen more frequently and at lower speeds for a longer period of time. i brought the truck into nissan with 70,000 miles, at which time i was told that the radiator leaked into the transmission causing the need for both to be replaced at the cost of $6700.00. i did alot of research and discovered that hundreds and hundreds of people with the 2005 nissan pathfinder with approximately the same mileage (just after warranty expires) are experiencing the same issues. it seems as though a faulty radiator system was installed into these vehicles. they kept my truck for 12 days while trying to decide if they would offer assistance with fixing my 5 year old vehicle. the end result being, that they would pay to replace the transmission and i would pay to replace the radiator as well as the labor costs. i was told that this did not occur as a result of anything i did wrong. i asked why a recall isn't being done, at which time i was told that the number of injuries or deaths was a major factor in that determination. although i was not injured, this is a huge financial burden to take on for a vehicle that is only 5 years old. nissan needs to take responsibility and stand behind the parts they put in their vehicles!! *tr
