Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: The 2005-2007 Pathfinder appears to have a widespread defect where coolant leaks into the transmission, causing transmission failure around 90,000 miles. Repair costs are typically upwards of $3,500.

According to the New York Times & a class action lawsuit, the defect actually extends through 2010 model year. More info here.

  • 121,000 miles


While driving with the family on a four lane freeway, transmission failure and immediate loss of speed in a rain storm. No warning or symptoms prior to the failure. Later found out that the radiator failed allowing coolant to mix with the transmission fluid causing catastrophic failure. Nissan assist was no help. Cost to repair quoted at $5700. No parts available for three weeks due to high demand. We did not have an accident due to the transmission failure, but it was very disturbing to make it off the freeway without getting hit from behind in the rain. My wife's vehicle and she was very thankful she was not driving when it happened.

The contact owns a 2006 Nissan Pathfinder. The contact stated the fuel gauge failed. In addition, the driver side mirror failed while the contact attempted to adjust the mirror. The vehicle was taken to the dealer numerous times for the failures. The dealer replaced the fuel gauge sensor. The contact stated that most recently, the transmission would exhibit failures and was slow to respond to acceleration attempts when in reverse. The manufacturer was contacted and they advised the contact to take the vehicle to the dealer. The driver side mirror and the transmission were not repaired. The failure mileage was 36,500 and the current mileage was 92,000. Kmj

While driving down the street at approximately 45mph the vehicle suddenly loss forward moving power but the engine would rev to a high RPM, causing a dangerous situation with the other traffic on the road while we attempted to coast to the side of the road. Upon taking the car to the dealer, I was informed that the radiator had experienced an internal failure causing antifreeze to enter and contaminate the transmission causing that to become damaged beyond repair. Although the power train (which I imagine includes the transmission) was still under manufactures warranty up to 60,000 miles, I was told it would not qualify for a warranty repair since it was determined that the radiator was the cause of the transmission failure and the radiator was only covered under a 3 year or 36,000 mile warranty. The repair costs for both were quoted to me from the dealer to be ~$6,000 for a new radiator and transmission. It is also my understanding Nissan has recently started to extend the warranty on certain Pathfinders faulty radiators (based off of VIN number) and would also reimburse anyone who already had to pay for this repair out of pocket. I have not received a letter from Nissan to-date stating my vehicle has qualified for this plan. Even though it is obvious to me (and the Nissan dealer) that my radiator was faulty therefore causing the damage beyond repair to my transmission as well. I feel I should be reimbursed for this very expensive repair since it was caused out of no fault of my own. Due to the extremely high dealer quote, I opted to have the vehicle repaired at an independent certified repair shop for ~$4,000 for which they installed a newly warranted transmission and radiator package. I was told they only sell the replacement transmissions with the radiators included, confirming to me that this type of failure is known to the industry as a combined failure.

I have 2006 Pathfinder, it has 48K miles and is overheating.I thought is was T-stat so I replaced it. It continues to overheat so I am reading this forum for answers. Please explain symptoms you were experiencing before radiator leaking into transmission was discovered. Any help is greatly appreciated. Thanks (this is my 2nd Pathfinder, we liked the 1st one so much we bought a 2nd. Never a problem with my 2001 Pathfinder.)

  • 50,000 miles
My check engine light would come on and off along with the gas gauge going crazy from empty to full. They replaced sensor after having to beg (cost would have been 700 dollars). This was just out of warranty. At about 50,000 miles my check engine light was on and they said they needed to replace a fuel sending sensor which cost me 300 dollars when it was in for that I needed both U joints replaced because the steering wheel and car wobbled horribly when hitting about 50 miles an hour. This wobble was horrible and thought it was the tires.. then had to replace two U joints ( second time since owning this 2006 Pathfinder).. I wish Nissan would step to the plate and recall the sensors and U joints.. its like everything happens just miles out of warranty. Probably last Nissan I will buy because of all the problems.

  • 85,000 miles
The contact owns a 2006 Nissan Pathfinder. The contact stated that the U joints were replaced twice within one year and needed to be replaced again. The dealer advised the contact to have the transmission and radiator rebuilt; however, the diagnostic test produced an unknown code pertaining to the fuel sending unit. The was concerned when she viewed numerous complaints, including NHTSA recall campaign id number 10V075000 (fuel system, gasoline: Storage: Auxiliary tank) but was unable to confirm if her vehicle was included in the recall. The contact stated that the manufacturer should be liable for the failure since they were fully aware of the issue. The failure mileage was 85,000 and the current mileage was 93,000.
