Problems with 2006 Nissan Pathfinder ENGINE

On average, the 2006 Nissan Pathfinder starts to “feel” problems with the ENGINE and its various aspects after 109 631 miles.

Recently reported ENGINE problems on 2006 Nissan Pathfinder

I was driving on an interstate at normal highway speed when the car shuddered as if going over rough pavement. the engine started racing, but the car gradually lost forward propulsion. i steered to the emergency lane and stopped. after a minute, the car regained just enough forward motion to get me to the next exit, across an intersection (where the light just happened to be green, thank goodness), and into the parking lot of a large grocery store before the vehicle lost all propulsion. we pushed the car the last few feet into a parking spot. it was towed to a nissan dealership. i was told the next day that the transmission warmer had failed, allowing radiator coolant to leak into the transmission, which ruined the transmission. the repair would cost $6000. i cannot put another $6000 into a 13-year-old vehicle, even though i've only had it for five months, so now i've lost the money i put into it and will have to start over with another vehicle.

While driving on the freeway or the city street, the car started to jerk and then suddenly cut off and lose power. this has happened at least five times at normal highway and freeway speeds in a straight forward motion. while on the freeway, i was able to glide over to stop the car and restart it. the car starts right back up and is drivable.the last time was on the city street, i was going about 35-40mph and the car again jerks and the engine cuts off and looses power. however, this time the steering wheel locked up preventing me to get over. i had to stop the car by breaking directly in the lane nearly causing cars to slam into me. again, once i come to a complete stop and put the car in park i am able to start the engine and drive again. after this first happened, i took my car in for a tune-up, oil change, and a diagnostic test but nothing read as an error. i do not drive far distances just mainly around town and have received regular maintenance on my vehicle. i am now afraid to drive my car because the lose of power does not happen consistently but is very dangerous when it does and can definitely cause an accident/injury/death if someone is driving too close. i looked up recalls and found recall10v517000. it says there was a recall for 2004-2006 nissan pathfinders but my vin # is not excepted. please look into this for this matter because i do not feel safe for myself and others while driving

Transmission is failing quickly. i had to replace my radiator a few months ago because it cracked. that event left my wife and children stranded on the interstate.

Radiator failed causing leak of radiator fluid into transmission causing vehicle to be towed to auto shop. vehicle was in motion on highway and then would all of the sudden no longer accelerate. mechanics, (got 3 estimates) all said same thing; that this was a problem with these pathfinders. my cost is about 6,500. i had just bought this vehicle for 8,500 about 3 weeks prior.

Tl* the contact owns a 2006 nissan pathfinder. when the contact started the vehicle and attempted to drive in reverse, the vehicle stalled. the vehicle was taken to an independent mechanic who initially stated that the fuel pump malfunctioned. the mechanic replaced the fuel pump, but the failure persisted and the vehicle would not crank. the independent mechanic stated that the engine control module failed. headquarter nissan (1725 whittlesey rd, columbus, ga 31904, (706) 225-8100) informed the contact that there was no recall on the vehicle. the manufacturer agreed with the dealer and provided a case number. the manufacturer stated that the vehicle was repaired per an unknown recall in 2011 and could not assist. the contact purchased the vehicle less than a year ago. the failure mileage was unknown.

Timing chain needs replaced pulled in and heard the tell tale buzzing sound had some one listen with stethascope to confirm

My problem is with the radiator and transmission fluid contamination.. some hoses inside the radiator that carries transmission fluid and coolant cracked and contaminated both the radiator and transmission. this problem has caused my vehicle to lock into 4 wheel drive and contaminated both my radiator and transmission this problem will need to be repaired before the vehicle can be driven. it will be a costly repair that should be covered by nissan on a recall according to all the complaints i have read about.

Coolant leaks into transmission. this ruined the transmission and should be recalled.

All 4 of my catalytic converters have had to be replaced (or need to be replaced - i've already replaced bank 1. now bank 2 is bad) in the past 12 months or so and now my radiator is leaking into my transmission. i discovered there was a class-action lawsuit on the radiator/transmission issue, but i'm outside of the warranty period. with respect to the catalytic converters, i occasionally smell exhaust, but the check engine lights stay on. with the transmission, it started out as gear slipping, causing rough driving (which the dealership told me was the catalytic converter). then, it started running slow out of first gear and hard shifting. i took it to a transmission place that pulled transmission codes and when they dropped the pan, the fluid looked like a milkshake. the rough driving/gears slipping didn't matter - it could be on the highway or in the city. i don't know the exact date in 2018 that i had the issue, but i've been dealing with this issue for a year.

Have a 2006 nissan pathfinder se, while driving at 65 mph the car shut off and i lost total power of the car and thankfully was able to pull over without getting killed. this has happened 2x i loos total power and the car shuts off. i called nissan to see if there was a recall and they said no, however there is a recall #10v517000 which nissan says my car is not involved in that advised this model had a recall for this very problem having the engine shut off while driving it. if there is a recall for this very reason and i have the make & model while nissan will not investigate why this is happened as it is a direct safety problem. i was told that i could take it into nissan for them to see what the problem was of course at my expense.

The radiator was cracked where the transmission fluid is and it mixed with the antifreeze which caused both the radiator and the transmission to have to be replaced. the engine was on and vehicle was stationary when we noticed the temperature increased greatly and rapidly until it maxed out. the vehicle was leaking a mix of antifreeze and transmission fluid. we replaced the radiator but the damage was done already to the transmission. the vehicle was in motion when the transmission failed.

Radiator coolant leaked into the transmission $4000 car 10 years old however i had high mileage due to many road trips

Defective radiator failed causing coolant and transmission fluid to mix that irreparably damaged the transmission.

Radiator fluid leaked into transmission, cause a replacement of transmission and radiator.

Tl* the contact owns a 2006 nissan pathfinder. on several occasions, while driving between 10-50 mph, the transmission failed to operate as intended. the dealer diagnosed that the transmission failed due to contamination of the transmission from the radiator fluid acid. the vehicle was not repaired. the manufacturer was notified of the failure. the approximate failure mileage was 170,000.

Timing chain is messing up which its clear that all nissan pathfinders made from 2004-2010 have that problem as well as the automatic windows not working going up or down when using automatic as well as passenger airbag light going off randomly. oh if it helps i worked at nissan north america manufacturing and i can't even begin to tell you how managers would send defected parts to the line for assembly because they would always say "quantity over quality". its a shame and i hope that this will help push to hold nissan responsible to fix what they already knew was bad.

The timing chain is a known issue with nissan usa. my timing chain has to be replaced at my cost due to its faulty design. engine failure due to the timing chain while driving and turning, left my wife stranded. this item needs to be recalled by nissan as there are thousands of complaints about this issue just after warranty expires.

I have a 2006 nissan pathfinder with 91,450 miles. i notice a slight slip in the transmission on the way to work. i work at a auto repair shop. they took it for a test drive and found nothing. approximately two weeks later, it really started to slip to the point i had to pull over, because it was not shifting correctly. when it was brought in to the shop again it did nothing. i called the local nissan dealer in stroudsburg pa and was told there was a "silent recall" and to check the fluid if it was a milky color, pretty much i was going to be without a car. i always took care of my car and for this to happen was a real blow. the dealership told me pretty much the repair exceeds the value of the vehicle. i did check the value of my car was approximately $6-7000 for the shape that it was in. that's a lot of money to lose on a vehicle. also, the hazard of not shifting properly could have caused an accident, i had to pull off the side of the highway until i could get it to shift and this kept repeating it self over and over. nissan had a class action settlement, which when i called nissan directly they said it did not include my vin number. i believe nissan knew this was a defect and only if you complained about it did you get attention from the company. i had an address change so i do not know if i received any information on this type of issue. i was the only owner of this vehicle and believed that nissan should make good for the repairs it will cost.

Takata recall- blown transmission due to radiator leaking coolant into transmission fluid, resulting in blown tcm and transmission. common problem with this make and model. vehicle was stationary when problem happened. no warning signs given from vehicle.

Radiator cracked leaking coolant into the transmission that is impacting the ability for transmission control module to function properly. now, while driving, the car randomly stalls and loses all power. while on the highway, it has become necessary to restart the car while rolling in neutral to avoid having to switch lanes into faster moving cars. i've been informed by nissan that it's a common problem and an $8000 repair to replace the radiator, transmission, transmission control module, and flush everything out.

Tl* the contact owns a 2006 nissan pathfinder. the contact stated that when he took his vehicle to the mechanic for maintenance, the mechanic stated that the vehicle coolant was abnormal. as a result, it was diagnosed that the transmission fluid and coolant had mixed. the radiator and transmission needed to be replaced. the vehicle was not repaired. the manufacturer was notified of the failure. the approximate failure mileage was 115,000. the vin was not available.

Raditor leaks coolant in transmittion now my transmittion is not working and the coolant has transmitton fluids in it

My vehicle had problems in 2011 when a "warranty notice" was sent regarding a radiator problem. i took the car in and they found that it was a timing belt and did not change my radiator while it was under the extended warranty and had approximatey 70,000 miles. i now have 160,000 miles and my car is acting up again and the dealership advised me the radiator is cracked and leaking coolant into the transmission so i need both repaired or my car will get worse and can cause an accident. to me it appears that this defect with the car was from the inception and it should have been recalled because it was bound to fail and it should be fixed at nissan's cost. my vehicle is still pretty good looking but i feel it is only a shell that i am driving because of the interior radiator flaw. they indicate that since no recalls were made i have to pay the total out of pocket. i missed the lawsuit in 2013 but am willing to file another class action lawsuit if a lawyer is willing to accept it. the vehicle was shaking when i was driving it on the freeway mainly and it felt like it was not in gear and pulling. these were also my concerns in 2011 when i took it in to be repaired and fixed, but they said i had no problems. well i do now and i wouldn't have if they had fixed the defective radiator.

Tl* the contact owns a 2006 nissan pathfinder. while the gear lever was in reverse, the transmission failed to operate. the vehicle was towed to an independent mechanic where it was diagnosed that the radiator connector hose leaked fluid into the transmission. the contamination caused internal damage to the transmission. the radiator and transmission were replaced. the manufacturer was not notified of the failure. the approximate failure mileage was 85,000. consumer stated while driving up a hill she acceleration and could not make it up the hill and made it to her job. consumer attempted to put the vehicle in reverse and would not go in reverse. car was towed, aamaco diagnosis was coolant had leaked into the transmission causing transmission to fail. updated 6/13/18*jb

Coolant leaked into transmission, destroying the transmission, and rendering vehicle useless without thousands in repairs

Right after purchasing this vehicle the check engine light went on. took it back to the dealer, they power sprayed the engine, said everything was fine. a few days later, vehicle is knocking. took it back, radiator fluid was in trans. replaced radiator and flushed trans. week later, same thing now worse. car is knocking load especially after hitting 40 mph. sometimes it wont pass 40mph.

We have a 2006 nissan pathfinder that has transmission failure due to a defective radiator. this is a known defect that nissan should be held accountable for. we followed all recommended maintenance, most of which was at a nissan dealership. the dealership was negligent in its inspection and repair of our vehicle. when we began to experience transmission failure and had both transmission and coolant contamination, they failed to diagnose the problem. two nissan dealership inspections in may 2016 outlined that all was well with our vehicle, even after we found that there was no transmission fluid on our dipstick, and it did not appear that the bolt to check the fluid had not been recently removed. our family's safety was put at risk driving this vehicle for over a month, while it was experiencing transmission failure and risked engine failure due to heavily contaminated coolant. after a few weeks of symptoms, we looked online and were shocked to see the widespread manufacturing defect that has been reported. we took our truck to an independent shop who diagnosed the problem. the nissan warranty was extended to 10 years or 160,000 kilometers for possible radiator assembly failure. although our vehicle fell within the 10 year time frame, we were outside the kilometer range by 40,000 kilometers. nissan canada and crown nissan refused to extend the warranty to us. we feel the 160,000 km is far too low for a 10 year warranty. a recent dodge warranty extension was 10 yrs, 240,000 km. nissan put us in an unsafe situation, where they failed to diagnose the problem and we were out driving for several weeks, some of which involved towing our family camper on the highways. nissan has been negligent on many levels and a recall should be extended to these faulty radiators.

Service bullitin classification em09-007, refrence ntb09-128, posted november 16, 2009. buzzing/whining noise from timing chain area. have contacted and stopped by dealership to inform them about issue i was having. showed tech there the service bullitin and they stated that they were aware of the problem and knew about the issue with numerous vehicles. i was given the only way it was covered by nissan was if the vehicle was still under factory or extended warranty. if it were not coverd that way then i, the customer, were responsible to all the cost and and rental fees if i chose to get one while it was in the service center. i was given the cost estimated at $1800 dollars and there was no guarentee that it would fix the problem.. and have a nice day. left very frusterated knowing there were thousands more in the same situation i'm in now.

I have had the coolant problem fixed. then i have had to replace all the u-joints. i have had to buy new gas caps to get my check engine light to go off. now there is a terrible leak and a noise that is so bad. i took it into a local shop and it is the timing chain. this car has been nothing but problems and now it is so bad that i can't sell it because no one wants it and i am now so upside down in my loan because the value is going down so much that i can't trade it in.

While driving on interstate 25 in south denver, my pathfinder began to sputter and stall. the engine started to overheat as i pulled into a service station about two miles away. i had it towed to christian brothers auto in parker colorado. a radiator part blew, the engine overheated and was destroyed. the steam from the plastic radiator part also damaged the main computer. it was close to $10,000 for all repairs related to the radiator part failure. approximately 8,000 miles later, my daughter and i were driving on i-70 near the vail, colorado exit, and the pathfinder started to jerk violently on the highway going 65mph. i was able to pull over to the side of the road. scary experience for us both. this happened today, 03/24/2016. smoke was coming from under the car. i had it towed to avon auto in avon colorado. they said the transmission is damaged, but they did not have time to look into it further. please call or email me with further questions.

Loud noise coming from engine . brought in to shop needs timing chains cost 1500. noow im told nissan new of the crappy parts and continued to use them

Vehicle is currently showing symptoms of the bad timing chain/tensioner issue reported by many other consumers. the repair will be expensive for a component that should last the life of the vehicle. should the component fail and result in catostrophic damage while driving, this will result in immediate loss of power steering and potentially cause vehicle instability and loss of control

I am an active duty marine and have served for over 20 years. my wife and i have been the original owners of this 2006 nissan pathfinder. while i was away on business my wife called me and told me the car was acting up. upon my return i test drove the car. the car would not acceleration after i came to a stop. soon after the engine light turned on. i took the car to the auto shop to get it checked out and found out the coolant and transmission oil mixed. i took the car into nissan and found out this is a common problem. nissan extended the warranty to cover this problem; but i was over the mileage and they would not be cover my vehicle. we recently paid off the car; however, now i am stuck with this ticking time bomb. the car loses acceleration very frequently. i have to turn it off and turn it back on to get it back to normal. while i am driving it, i could feel the transmission disengage. it sometime feels like i am driving over a bumpy road. it may stop working anytime. i am getting ready to deploy and i am stuck with some tough decisions. buy a replacement car, pay a lot of money to fix this car, or drive the car until it stops working. i don't want to leave my wife and son with this problem while i am gone. please help.

My cars radiator cracked and leaked into the transmission. the mix of coolant and transmission fluid damaged the transmission and quite possibly damaged my engine. nissan knows about the radiator because they extended the warranty on it. the repairs for this incident are high the nissan dealer i took it to quoted me $4,591.43 to replace the transmission and the radiator and that is with the warranty they claim they have on it. the dealer also told me any other damage caused by this faulty radiator would not be covered and i would have to pay for the repairs to any other components as well they told they me might be an additional $2,000 so nearly $7,000. i had know choice but sell the car off as scrap as the repairs would cost more than the car itself. a failure of all these parts at once is a safety hazard to everyone.

The moment i purchased this vehicle it had check engine light and transmission problems and catalytic converters were bad. would not pass inspection.

I backed out of my driveway onto the main road and went to put the vehicle into drive and it would not go into drive. when i got it to the repair shop they said that the radiator had leaked into the transmission and caused it to ruin the transmission.

Radiator fluid has leaked into the transmission causing it to fail. the dealership has issued a fix where the radiator coolant is bypassed from the transmission but then that has not helped. the fix was for $500+ the repairs for the transmission are at $4700/- now. this is ridiculous the amount of repairs is more than the cost of the vehicle now.

Purchased vehicle from car lot feb. 28, 2015. drove this vehicle 5 times and the coolant leaked. flushed system notice there was stop leak in radiator. now my transmission slips and truck shakes during acceleration. this was a previous issue before i bought the vehicle because the shaking occurred when driving home. i thought this was just the tires needing to be balanced, but after research i know that it was from the coolant previously leaking into the transmission, and now i am left to deal with it. *tr

The transmission started to slip, which needed to be taken out of overdrive from time to time. after a few months the transmission gave out completely on the highway. it will rev up, but will not drive. apparently they are famous for the gasket leaking engine coolant with the oil. they should have all been recalled. *tr

Car shut down on dart train tracks, transmission failed to work, radiator had oil and leaked into transmission. *tr
