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.

2005 Nissan Pathfinder Owner Comments

Pathfinder 6-cyl

  • 99,480 miles


Crack in the radiator assembly occurred leading to internal leakage of the engine coolant. 2005 Nissan Pathfinder with automatic transmission began hard shifting in the fall of 2010. This was a constant daily occurrence if the driver forgot to take the Pathfinder out of overdrive. It sounded like the old 1970S Ford universal joint as it shifted into gear. At times the car felt like the back-end was being pulled in the opposite direction. At cruising speed, the back wheels would sound like they were running over the corrugated concrete near a toll booth or lane dividers on a highway and the transmission would cause the car to shudder. It would seem to fall out of gear while the car was moving at speed. Going uphill, the Pathfinder would hard shift and hesitate to engage into gear. Accelerating on to the freeway was never an issue, but it would not immediately shift into the appropriate gear at highway speeds. On several occasions, it would stay in neutral when shifted into reverse. The most common symptom was the shuddering noises at 30 mph. If the overdrive was turned off, all symptoms would diminish or disappear completely. Took it to the dealer in December and they could not duplicate. Took it to the dealer in may and they could duplicate, but not consistently and saw no mixing of coolant and transmission fluid. Towed it in to the dealer in August, the damage is done, the fluids have mixed and the transmission computer has shorted out. Repair recommended is to replace transmission (including computer) and radiator and hoses. Customer cannot afford the $6,000 price tag on the repair. Nissan North America will not assist as Pathfinder is out of warranty.
