2005 Nissan Pathfinder: sudden loss of power

Filed Mar 19, 2019 · Transmission · 80,000 miles · GA

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.

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?

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

Me and my 6 month old daughter were going down the road when my car lost all power and was like it had been shifted into neutral. My brakes weren't working properly but I got us off the road and had the car towed. After our repair guy checked all the wiring and ran test and pulled the transmission pan off the radiator coolant had leaked into the transmission full resulting in the gears messing up and the entire car undriveable. We knew about this problem and had contacted nissan 6 months prior to check the recall and was told this vehicle had been fixed....obviously not. If it had been fixed it wasn't fixed properly or it would not have failed again many trips have been taken since then and now we are over 100,000 miles and it's a $3800 fix because nissan either lied and it was never fixed to start with or didn't correctly fix it the first time.

The vehicle began a slight shudder when shifting and within a few days while passing a truck on the freeway at 70 MPH it shifted very hard and responded as if it was in neutral. Any application of the accelerator caused high RPM but gave no additional power. I was forced to put on my emergency flashers and maneuver through three lanes of traffic as I had lost all power and could not was just coasting along the freeway. It was a very dangerous situation that fortunately ended safely no thanks to the car. It was later determined by my mechanic that the radiator fluid had mixed with the transmission fluid and caused the transmission components to fail. After spending $1000.00 on the first repairs to replace the radiator and flush the transmission 3 times it ran for a week and began shifting very hard again. It is now in the shop being considered for a transmission replacement. Hearing about the investigation and similar experiences by others it is a wonder why this issue has not been officially deemed a safety recall seeing as how my safety was definitely in jeopardy at the time of the failure.

The vehicle engine timing chain had made a slight "whirring" sound for many months - nothing really loud enough to cause alarm, but noticeable. Then when idling the vehicle in my driveway, the engine began to whine loudly, and then all of a sudden the engine lost power and began to emit a loud slapping/ clunking sound. The problem is that the timing chain has failed and the chain is slapping around inside of the timing cover. I was lucky that the vehicle was idling in my driveway at the time! There are thousands of reported incidents to be found on the internet where nissan owners have reported that timing chains have failed, and some owners in california have filed a class-action lawsuit to force nissan to acknowledge this factory defect. Nissan knows about this problem - there are factory service bulletins to repair this problem, but no recall. This engine defect is dangerous - engine failure on busy ny / nj / ct highways can be life-threatening!! Why is the nissan timing chain defect not deemed a mandatory factory defect recall?? As a former mechanic, I can say with confidence that modern vehicle engine timing chains can be reasonably expected to last the life of the engine! Timing chains are not considered a regular maintenance item! Not only does timing chain failure put the vehicle passengers in extreme danger, but is very expensive to repair. Why should consumers have to bear the financial responsibility to repair a factory defect? At this time the vehicle is sitting "dead" in my driveway - I do not have $2000 required to repair the factory defective timing chain assembly! Please force nissan to recall and repair their defective timing chains!!!

I was driving the car and when on the onramp of the freeway, the car lost power and shut down. Nissan dealership said the radiator leaked fluid onto the transmission causing it to loose power. They said I need a new transmission and radiator but will not cover the warranty which was settle in us district court of new york. They want to charge me $5300 for the repairs. This is clearly a faulty design of the nissan pathfinder series and website searches verify that the problem exits for thousands of nissan pathfinders for the years of 2005-2010 in relations to a radiator crack and fluid leaking onto the transmission.

Vehicle lost power while driving and won't accelerate. Checked the fluid levels and they all are ok, however, transmission fluid color appears brownish instead of the usual pink color.
