Pathfinder 6-cyl

  • 93,000 miles
Problem with the radiator and transmission fluid mixing. Told that this happens often with these trucks. Recommended to either have the radiator replaced and double flush the transmission for $1200, or opt to replace both radiator and transmission by Nissan and pay a co-pay of $3000, plus\tax. If this is a problem with these trucks then Nissan should fix their products.

Transmission oil in radiator, cause car to over heat. Most likely need new transmission and radiator. Just over Nissan 100,000 mile warranty and they won't cover the replacement. And if the would want me to pay 3,000 out of my pocket for a know defective part. I feel this needs to be recall and Nissan expense and fix my car.

My problem started with my 2005 Pathfinder over a year ago, I went to the Nissan dealer they told me that I need to drop off my vehicle for them to fix it I asked if Nissan covering it they said no I have to pay $2,500. This is not my fault it's their problem. Why do I have to pay for them to correct their problem with a radiator leaking and messing up the transmission?

2005 Nissan Pathfinder. Consumer states problem with vehicle transmission the consumer stated while driving, the check engine light illuminated, as well as the 4-wheel drive light. The vehicle started hesitating. When the consumer called the dealer, they advised her to open the gas tank, to see if a puff of air came out. Once she told them no, she put the vehicle in drive and it would not move, she then put it in reverse, and it still did not move, . the dealer then advised her to disconnect the battery for a half hour. She reconnected the battery and drove around the block and it stalled. The consumer had the vehicle towed to the dealer. An inspection revealed a problem with the transmission. The dealer stated a gasket between the radiator broke and anti-freeze leaked into the transmission. The dealer informed the consumer, it would cost $6,000 for the repairs.

Pathfinder 6-cyl

  • 92,000 miles
I was traveling on interstate I-95-N near exit 7 at a high rate of speed, my transmission failed due to a crack(fault )in the radiator assembly unit. As I attempted to exit the interstate while losing speed, I was almost rear ended by a tractor trailer and hit by another car. Eventually, after coasting down hill to an intersection of center of new england/ new london turnpike, had to get out and push the vehicle with help from other persons to nearest service station. Nissan extended warranty on radiator assembly unit to 8yr/80,000. I have 6yrs+/92000, took extremely good care of this vehicle and am now being told I need to pay $6,500 to fix vehicle (while I still owe $12,000). Should have been a recall before someone gets killed (if not already) and /or the warranty should be offered for at least 120,000 miles. What a poor attempt to cover up an obvious design flaw, while trying to hide from their obvious liabilities for this situation.

Pathfinder 6-cyl

  • 115,000 miles
2005 Nissan Pathfinder. Took off out of parking garage, car lost power (wouldn't accelerate) and the service engine soon light came on. Took car to independent shop who advised that the computer code they were receiving from the car was a manufacturer code and I would have to take it to the dealer. Took car to dealer and was told that radiator had failed and caused the coolant and transmission fluids to mix, resulting in damage to the transmission. Recommended repair was replacement of radiator and transmission with an estimate of $5,200. I bought car at 48,000 miles from the dealership as a Nissan-certified pre-owned vehicle. I've had multiple problems including replacing the fuel sending unit as well as a catalytic converter. The car had 115,000 miles at the time of the incident and I contacted Nissan to request assistance with the cost of the repairs but was denied any help.

First time- transmission failed- new one installed under extended warranty- has gone bad again last week- they tell me the coolant is leaking into the transmission and has ruined it, the gas tank needs replacing, new radiator, new catalytic converter, new U-joints for the second time. My extended warranty has expired- they are telling me that I need $8000 worth of repairs to fix the problems. That is more than the vehicle is worth with 155,000 miles on it!!! please help.
