Problems with 2005 Nissan Pathfinder POWER TRAIN

Tl* the contact owns a 2005 nissan pathfinder. while the vehicle was at a stop sign with the brake pedal depressed, the engine revved and the vehicle accelerated forward into traffic and suddenly stopped. the maintenance, 4wd, and check engine warning indicators illuminated. also, the gear shifter symbols were blank. the vehicle was taken to an independent mechanic who stated that the transmission fluid had a burning odor. the transmission was replaced, but the failure recurred two days later. additionally, while driving 35 mph, the vehicle became stuck in first gear. the vehicle was towed to the same independent mechanic. the local dealer and manufacturer were not notified. the failure mileage was 131,000.

Radiator internally failed causing fluids to mix. coolant was run through the transmission causing it to fail.

I bought the vehicle having no idea of this issue, i didn't investigate because this is our 7th nissan and they have been good cars. i was driving 75 mph to work at rush hour and the trans started letting loose and shuddering so bad i had to pull over onto the should and that's just as safe as driving this thing. paid a lot of money to have it sitting in the driveway. but everyone that asks why i tell them because nissan doesn't care about their loyal customers. we intended for our 14 y/o to drive it but no way in the world would i let that happen

Complete loss power and transmission problems shop, the diagnose was a failed transmission fluid cooler integrated into the radiator that allowed engine coolant to mix with and contaminate the automatic transmission fluid. the vehicle did not report any warning signs before the failures other than a sudden loss of ability to move the vehicle. my pathfinder is 2005 with only 81000 because i am in the military and i did not drive it, and i have no report of a recall.

Coolant damage transmission. the car lost power in motion

Known to nissan corp, a design defect makes the engine radiator rust and leak into the transmission. my car has always been properly maintained and i jus took it to perform the 90,000 miles service. coolant fluid was found in the transmission oil and dealer quoted me $6,884.59. after a class action lawsuit i just learned about, nissan has extended the warranty with partial copay up to 10years/100,000 miles whichever comes first. my vehicle is now out of warranty. this is something unacceptable and nissan should be held accountable and fix it for free for life.

Was sitting at a red light on the way to work. light turns green tries to accelerate and hardly anything happens besides a whining noise. radiator fluid has leaked into transmission fluid causing a milkshake like fluid mix. now nissan dealer wants me to replace radiator, and transmission on my on dime. i have seen several forums where this has been the case. now nissan has not recalled this vehicle for any safety fixes of the nature.

Transmission started slipping. when i took my vehicle to the dealership, radiator fluid had leaked into the transmission causing me to have to replace not only the transmission but the radiator, hoses, etc.

Transmission went out while with 2 small children in the suv. i had only had the suv for 4-6 months. transmission was repaired by dealer service department . shortly after the radiator needed repair. it was repaired, and nissan helped with partial cost. recently (02/19/2018)transmission went out again while yielding in a busy intersection to go on the highway. transmission went out a second time on 02/22/2018 again. i was stopped at a light, the light turned green and i began to push on the gas to make a left hand turn in a busy intersection and once again, the suv only coasted. i took the vehicle to nissan service department, paid 110.00 for a diagnostic test and was informed once again the transmission needs to be replaced. a 6,000.00$ job. the transmission has only been about 4-5 years old presently. i am out of a vehicle.

Tl* the contact owns a 2005 nissan pathfinder. the contact took the vehicle to the dealer (melloy nissan, 7707 lomas blvd ne, albuquerque, nm 87110, (505) 545-6420) for a routine oil change and inquired about failures with the transmission; however, the dealer found no failures. the contact stated that the vehicle's transmission malfunctioned and would not shift gears. the contact took the vehicle back to the dealer and was informed that the radiator was cracked and the fluid seeped into the transmission fluid. the repair cost would exceed $5,000. the manufacturer was not contacted. the vin was not available. the failure mileage was 81,957.

My vehicle was recently diagnosed stating that the radiator had leaked fluid into the transmission and it would cost $6,200 to repair. my vehicle has 85,000 miles. i was never made aware of the extended warranty when i could have had it checked (the dealership did replace the transmission fluid once so the issue should have been taken care of then when it was under warranty). there is a vibration when the rpms settle around 1000-1500 after the vehicle has warmed up. it is intermittent, but was diagnosed by the nissan dealer mechanic as the issue.

Traqnsmittion oil in coolant had to have shop flush out raiadiator and coolant system and replace oil cooler transmition seems to be sliping

The issues with the vehicle began at 133834 miles. when driving, at times it would vibrate out of nowhere. after a stop, it would shift up hard or fail to downshift and then hit hard when it finally would go in to gear. once i took it in to a mechanic, the following codes came up: p1731 - 1st gear logic error, p0430- cat efficiency bank 2, p0455- evap system leak large. the recommendation was "tear down". in the end, i had to replace my: transmission, radiator, torque converter, valve body, valve body solenoids, catalytic converter bank 2, exhaust gaskets, oil pressure sensor, and oxygen sensor. with a total cost of $4,824.65. i will upload the services my nissan pathfinder had to have.

Radiator fluid has leaked into the transmission, compromising the integrity of the transmission. i feel a shudder when the transmission hits 40 mph - 60 mph.

Car has experienced leakage from the transmission cooler radiator to the automatic transmission, causing the transmission to fail. we will need to have it rebuilt, which will cost us $4,500+. we may also need to have the radiator replaced. nissan knew of this problem years ago. they didn't do a recall or issue a service bulletin to owners of these vehicles, which is unconscionable behavior.

Purchased vehicle in 2005. in 2017 took to dealership with problem of loss of power to transmission on freeway while my daughter needed to pull over due to problem. problem of noise in engine timing belt was also told of at dealership. with extended warranty of 10yrs./100,000mi. they said they were not liable & needed $6971.28 to repair. vehicle had 80,825 miles on it but was two years out of coverage. after finding out in 2013 a lawsuit was filed by mendelsohn and mazie slater katz & freeman for known defect to nissan, problem was never contacted to me for some reason? was just informed by falco v. nissan notice administrator to file paperwork on known problem with engine timing belt for possible 20% return of payment made to repair of defective tensioner assembly. why four years ago was i not informed of radiator leak causing possible damage to vehicle & possible injury to driver?

The radiator cracked where the transmission line runs through it. this caused the tranny fluid and coolant to mix and ruin the transmission. i noticed a severe vibration at 40-60 mph which almost caused me to get into an accident. these are very dangerous to drive on the highway with this issue and may lead to severe accidents. the radiator and transmission should be recalled.

Tl* the contact owns a 2005 nissan pathfinder. while driving 55 mph with the cruise control activated, the rpms accelerated and the vehicle stalled without warning. the vehicle was able to restart on the first attempt, but the gears failed to shift. the vehicle was towed home. it was diagnosed that the transmission was flooded with water and the radiator needed to be replaced. the radiator was replaced, but the failure recurred. the manufacturer was made aware of the failure. the failure mileage was 179,000.

Takata recall

Radiator coolant leaked into the transmission rendering useless. corroded and destroyed whole interior of transmission .

At almost 70,000 miles, i started getting a vibration when accelerating at or above 40 mph. i was told by the nissan dealership that it was coolant intermixed in the radiator and transmission and they needed to be replaced at a cost of $6800. nissan knew about this problem back in 2007 and didn't notify owners. not happy!

I was stranded in a parking lot because my car would not start. after having it towed to the dealership, i find out it is the "intermix" between the radiator and the transmission. i never received any information about this from nissan, but now understand it was a known and frequent failure - by design. essentially, after 90,000 mile, the car is worthless because of this issue. after paying $5,000 for the repair, i drove off the lot only to have my fuel pump fail. literally, i drove off the lot and the engine began misfiring. unbelievable. *tr

Started loosing speed while driving on the interstate with my daughter in the suv with me, so scary. but i managed to coast to the nearest exit roll in time for it to get to 0 on odometer. then had it towed to my home. few days later took to two different auto repair shops(towed to 2nd shop because suv would not go pass 20 and it would just stop once down to 0)who informed me there were transmission issues, final shop said the radiator ruptured causing water, transmission fluids, and etc to all mix which has caused transmission to go bad my options are to rebuild, but another transmission or let the suv go..upongoogling to see if others have or had this problems i'm totally not alone and yes i'm pass the 50,000 n 100,000 range however i still think some etching shouldbe done, being i took n trace very gd care if my suv only allowing nissan to repair and maintenance my suv. i was told to repair this will cost me 3900 plus. i shouldn't have to pay any to be honest but done type if help would be greatly appreciated for not only me but everyone experiencing this issue. *tr

Driving and came to a light and the car would not move forward or reverse.

2005 nissan pathfinder 92,000 , vehicle won't start and had it towed, was told it was due to the radiator leaking into the transmission. after having spent $800 @ vadan nissan, because my car would jerks and stop whilst driving, was told it was a coil problem, and a sensor issue, nothing was ever said to me about this huge problem the 2005 to 2010 pathfinders are having, totally disgusted with nissan.

Takata recall i have coolent in my transmission due to radiator failure causing my transmission to slip causing my car to crash into my house in my carport the repair for the transmission is $3800 and i'm on a fix income

Transmission failure on interstate had to be towed home 50 miles

Transmission shutters repeatedly while picking up speed. it is increasingly getting worse. now, once the vehicle has been driving awhile- the transmission shifts hard and doesn't want to go past 20 mph once you stop and then go again. it sounds like i am in neutral while trying to accelerate. once it cools, the process starts over.

8/31/2016 - check engine light came on during normal driving, i brought it to my local mechanic for inspection which showed the transmission has failed. this is due to the radiator and transmission intermix problem is how nissan notes it and validated by my call to the local nissan dealer. the car is outside the nissan extended warranty period for this issue which is 10 years but well under the 100,000 miles as it has 80k miles at time of event. nissan is unable to offer any financial assistance so the out of pocket cost to repair ($5-$6k) makes it not worth the repair so i'm stuck with a car that to date i have maintained very well. there was not warning signs and i am sure this problem has been going on for some time as it does not happen overnight. very disappointing that nissan does not take ownership of the problem that has plagued hundreds of nissan pathfinder owners.

Transmission failure

Pathfinder 2005 has only 73,000 miles and now has a problem of cross contamination between transmission and radiator fluids. requires replacement of transmission. very expensive - requires to replace transmission and wash radiator. transmission does not shift properly. problem confirmed by the dealer shop as well as am independent car shop.

I needed to change all sensors because check engine light and the dvd and slip light stayed on.now it will not start all the time and if it does it will die in the middle of traffic.it had to be towed to dealer.

Vehicle would barely pull out in drive, just stopped pulling. checked fluid in transmission and its a milky color. radiator coolant is milky brown.

Purchased a used 2005 nissan pathfinder. had the vehicle about 2 years. driving home one day the vehicle started to loose power as the rpm's started to spike. we had to pull off the road in a very unsafe spot because the car could no longer move. there were no warning signs of the transmission failing. we had the vehicle towed. with a quick glance into the coolant tank, seems to have a mixture of coolant and transmission fluid. repair cost are estimated from 2500 - 5,000+. something needs to be done about this problem.

Our 2005 pathfinder lost all power while driving on a local highway in our town to take our daughter to school. it has an automatic transmission and would not change out of first gear. we live up on a slight hill, and it honestly felt like i was pulling a semi behind my vehicle just to get it back home without requiring a tow. needless to say we had to keep both of our children home from school that day because this is the only vehicle we own. it angers me that nissan refuses to make a recall on this issue!! this transmission issue has caused us to be without a vehicle for almost a month now!! it's not always easy to find people that are willing to help you out long term!! this is a huge inconvenience to our family, & we don't have the money to pay out of pocket to get this fixed. a local mechanic near where we live said he has seen this issue tons of times, and has fixed numerous amounts of nissan vehicles due to the crack that causes the antifreeze & transmission fluids to combine and mess up everything in the transmission over time. with this being an issue on nissan's part, i feel that they should pay to have the problem resolved!!! my husband is out of work due to an injury and will be out for an undetermined amount of time. i work part time at a local bbq restaurant in our town, and don't bring home very much each week. i pray the corporation will do the right thing and finally recall all the vehicles affected by this. $3500 dollars is the best we can find & when it gets fixed, the person we have spoke with said they will bypass the radiator when the transmission gets reinstalled making sure we never have this problem ever again!!!! sadly we don't have the money for the repairs or i would not be making this complaint. if anyone knows of any information that i don't know of please let me know!!! i am desperate to get my vehicle back!!! we have no one to help. thx

Tl* the contact owns a 2005 nissan pathfinder. while driving 25 mph, a burning odor emitted from the vents. the vehicle was towed to an independent mechanic where it was diagnosed that the transmission failed. the vehicle was repaired. the manufacturer was not notified of the failure. the failure mileage was approximately 134,000. updated 12/01/16*lj *tr

When driving about 40 most speed limit it felt as if i was driving on safety strips on the highway like strudder.

Contamination of transmission fluid on 2005 nissan pathfinder. color of coolant is purple and cloudy in overflow and radiator. transmission has started shuttering between 35 - 45 mph. symptoms began at 130k miles.

Coolant and transmission fluid are mixing! the transmission is starting to skip and the coolant is milky/ creamy looking and i added 3 quarts transmission fluid 7days ago and now have to add more. the coolant is being pushed out of the overflow do to the transmission fluid and coolant mixing together.

Vehicle has service engine light came on. vehicle would not shift gears properly while in traffic and occur sporadically. diagnostic code revealed p1754 a known issue with transmission and radiator.

Water in transmission oil due to bad trans cooler wich is a known problem w/ these vehicles by nissan but was never recalled.

The dreaded coolant leakage from a faulty oil cooler causes failure of transmission and radiator.

2005 pathfinder drives great at lower speeds, but occasionally sounds and feels like i'm going over rumble strips at speeds higher than 40 mph. took it to nissan and was told that we have the well known issue where the radiator cracks and leaks into the transmission, ruining both. the car has 95,000 miles on it and nissan will do nothing to help. the nissan dealership wanted $6,500 to fix. now i'm reading that this could have been avoided with a work around. this should have been recalled, or at the very least, information given about the work around to fix prior to the trans going out.

Tl* the contact owns a 2005 nissan pathfinder. while driving at an unknown speed, the vehicle vibrated roughly. the failure recurred numerous times. the vehicle was taken to a dealer where it was diagnosed that the transmission and the radiator needed to be replaced. the vehicle was not repaired. the manufacturer was not notified of the failure. the vin was unknown. the approximate failure mileage was 111,000.

Tl* the contact owns a 2005 nissan pathfinder. the contact stated that the transmission was slow to engage and the contact was unable to drive the vehicle over 50 mph. the vehicle was not diagnosed or repaired. the manufacturer was notified of the failure. the vin and failure mileage were not available.

Transmission was damaged due to coolant leaking in from a cracked radiator

Ecm replaced under recall. radiator/transmission replaced @ 96k miles under "extended warranty." transmission replaced 2nd time 1 year later. transmission hoses replaced twice (during same time period). now - 103k miles - check engine light came on: vias solenoid valve, bank 2 catalytic converter, & oil pressure sensor switch all need replaced (possibly related to ecm relay issue)

Transmission failed. design also caused need for new radiator.

Approx. 1 year ago i noticed that my engine coolant had trans fluid in it so i looked online and found the extended warranty. i then took the pathfinder into hamilton nissan in hagerstown md. they replaced the radiator and installed a rebuilt transmission. about 3 weeks ago i noticed that the pathfinder was not shifting into overdrive. now the transmission will not shift into overdrive and now slips in and out of 2nd and 3rd gear. this is very dangerous. i was almost t-boned this morning because the pathfinder would not go into gear while the trans was in drive, which is why i am submitting this complaint.

Transmission radiator ruptured. coolant flooded transmission and destroyed transmission. this ruptured occurred while vehicle was in motion traveling on interstate.
