My vehicle had given no signs of problems. I had my vehicle serviced, oil changed...etc on regular basis. Friday November 9th I left work and my vehicle wouldn't start. The Nissan dealer I took my vehicle to has informed me that a faulty radiator tank broke down, leaked coolant into my transmission, corrupting my transmission and all the electronic components that allow the vehicle to identify my transmission & give the vehicle/transmission ability to start. In addition they indicate it caused corrosion and has destroyed my transmission. I have been told that Nissan knew of this problem/exact issue but instead of recalling the radiators, they "offered" an extended warranty up to 8 years/80,000 miles (whichever comes first): No customer co-pay; after 8 years/80,000 miles (whichever comes first) up to 9 years/90,000 miles (whichever comes first): Customer co-pay is $2,500; after 9 years/90,000 miles (whichever comes first) up to 10 years/100,000 miles (whichever comes first): Customer co-pay is $3,000. I think its asinine that they can get away with not recalling all of these and taking care of a problem they know about without putting a huge burden on all of their customers.

My Nissan quit due to a failed transmission. I was driving and without warning when I accelerated it would not go forward. It occasionally would do a hard shift when going down hills or increasing speed. I began to smell a foul odor coming from the hood and alot of smoke billowing from the back of the car.

Pathfinder 6-cyl

  • 96,000 miles
This complaint is regarding a 2005 Nissan Pathfinder. It is common to this model and involves the intermingling of coolant and transmission fluid due to the faulty design involving these systems. The result is ruination of both the automatic transmission and the radiator, in addition to various associated components. Please, compel Nissan to issue a fully-covered recall on this defect. It is an obvious design flaw and the fact that the consumer is currently forced to bear the significant burden of the substantial related repairs is absolutely ridiculous.

I was leaving a restaurant parking lot with my wife and kids. I pulled to the parking lot exit and turned right onto the 4-lane boulevard. I tried to accelerate to traffic speed in the near lane but the motor simply raced and would not propel the vehicle. As traffic caught me I heard tires squealing and horns blowing from the vehicles behind me. The traffic worked around me while I shifted the transmission into park and then back into drive and began to move at idle speed. As traffic allowed I worked over into the left lane and then the turning lane while gradually accelerating to driving speed, merged back into traffic and proceeded home, careful to avoid any stop lights in busy traffic. We are fortunate that we were not involved in an accident. I'm no expert, but I do know that a vehicle that suddenly won't propel itself in traffic is as dangerous as one with no brakes. This was the one and only time that we experienced this problem. There was no previous indication that anything was wrong. I took the car to the Nissan dealer and they diagnosed the problem as a transmission coolant line failure which allowed transmission fluid and engine coolant to intermix in the radiator, engine block and transmission, which in turn caused the transmission to slip. I'm sure NHTSA has received many complaints about this problem. I'm hearing many of the same complaints just in my area and likely there are others that have not yet been reported. Hopefully no one will have to die or suffer serious injury because of this unsafe condition before a recall will be issued.

Pathfinder 6-cyl

  • 150,000 miles
The car was being driven on a busy street during morning rush hour, at approximately 40 mph. The car immediately stopped running and went to a crawling speed (around 1-2 mph). Cars behind needed to move quickly to avoid collision, and because there was no shoulder, the car blocked traffic. The car was taken to a Nissan dealership. Their first diagnosis was that it was a failure of the automatic transmission valve body, and they wanted to charge around $2400 for the repair. Three days later, after looking at it, the dealership diagnosed the problem as coolant leaking into the transmission, with a cost of repair of $7400.

  • 137,200 miles
My vehicle quit driving in the middle of traffic. It would only idle when I pressed the accelerator. I was notified that my radiator had an internal leak and the coolant was mixing with my transmission fluid which caused my transmission to shut down. I was notified when searching for a radiator, that this has been a common problem with the vehicles and is documented with complaints all over the internet. I am currently a nursing student, and I do not think it is fair that I must pay for repairs that are not my fault when I am not able to afford them. This has been an extremely costly repair and I have been forced to take out a loan to get my vehicle repaired so I will have transportation to school.

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

Many instances of the car jerking, jerking forward when trying to slow down or stop. The RPM revving up to dangerous levels for no reason and trouble driving uphill. My car has become a major safety issue. First the fuel gauge stopped working, which caused me to run out of gas and stalling in the middle of an intersection. Next, my car stalled for no reason while driving, that was repaired, something to do with a relay switch, now the transmission issues, possible radiator failure and the need of a new catalytic converter in a car with 100K miles.... that's insane !!! someone is going to be seriously hurt or killed if they don't fix these vehicles and people don't have thousands of dollars laying around to fix it. So, no food, rent or bills being paid for over a month just to pay for repairs is even more of a hardship to families. Please help us before something happens. Thanks !!!

Driving vehicle and suddenly lurched forward and wouldn't drive. Taken to shop and said defect in radiator allowed coolant into transmission ruining both components. This is a known complaint which Nissan fails to address. They uped their warranty when problem was seen but mostly happens outside of the warranty. I spoke with a customer service rep and she said there was nothing they could do even though they are aware of the problem.

Radiator and transmission fluid mixed. Internal radiator failure caused damage to transmission. Causing loss of power when driving. Nissan is aware of this problem and refuses to step up to the plate. It is a defective radiator and it can become very dangerous if it happens on a very busy interstate. I have chosen to let my vehicle set. I don't want to cause a fatality to myself or my family. Please help not to let Nissan get by with this. Updated IVOQ 01/02/13
