2006 Nissan Pathfinder Owner Comments

Pathfinder 6-cyl

  • 101,000 miles


When I try to accelerate, my vehicle shakes and the speed does not increase. I had the vehicle looked at and I was told the transmission fluid is mixing with the radiator. There is a purple slime under the radiator cap and there is corrosion under the cap of the overflow. This will cost thousands of dollars to fix which I can't afford. Trying to merge in with traffic is dangerous since the vehicle doesn't always accelerate.

Transmission and radiator fluids mixed and caused a major lock up and overheating in the car. The transmission was destroyed and the radiator needed to be replaced. Nissan is aware of the malfunction but failed to notify or do anything about the issue. This is not only a safety risk, but a mechanical risk to the owner and Nissan should at least notify the owners of this potential risk.

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.)

I had my Nissan Pathfinder recommended serviced at the Nissan dealer performed on June 26 2010. They advised me my truck was in good condition. After leaving the dealer my truck started jerking and I returned to the dealer. The dealer informed me my transmission and radiator were leaking and had to be replaced. After researching online there is several complaints from other Nissan Pathfinder owners with the same problem. I feel Nissan should recall the Pathfinders. This is a safety issue because the Pathfinder is jerking and stalling.
