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.

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.

Vehicle would hesitate badly while driving and almost caused an accident. When taken to a mechanic to fix issue, we found that the transmission fluid had turned pink. The technician stated that at fluid and coolant had mixed together. We had to have the transmission and the radiator replaced.

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.

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.

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.

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.

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.
