Transmission Gear Slipping problems of the 2005 Nissan Xterra

125k much like several other customers the transmission started slipping and have been informed that the vehicles contains a defective radiator cooler tank that ruptures and forces coolant into the transmission through the cooler lines. When the coolant mixes with transmission fluid it creates a frothy liquid that eats valves, erodes seals and causes corrosion. Waiting to see what cost would be to replace system but have been told its around 5k and the car is not even worth that!!.

The contact owns a 2005 Nissan Xterra. The contact stated that while driving approximately 60 mph, the transmission began to slip gears before becoming inoperative. The engine was turned off and upon restarting, the vehicle resumed normally. The vehicle was taken to an independent mechanic who informed the contact that the transmission fluid had turned into a dark brow, almost black color. The vehicle was not repaired. The manufacturer was notified of the problem. The approximate failure mileage was 125,000.

Transmission started slipping in high gear, because of a leak from a known faulty radiator letting coolant into transmission.

Driving on freeway and transmission began to slip and within a matter of seconds had absolutely no power to wheels. Have researched and found issues with this vehicle regarding coolant line for transmission failing and leaking anti-freeze into transmission. Was wondering why it is that there is not a recall by Nissan for this issue as it is undetectable, unpreventable, and expensive.

My 2005 Nissan Xterra started having some problems early in July. On or about July 5 I was pulling onto highway 30 in montgomery illinois. There was oncoming traffic. I pushed the gas and proceeded to merge on to the highway. The car moved very slowly almost causing an accident. I pulled over out of traffic and rested car for approx 5min. When I began to accelerate again the car performed normally. I took to a mechanic who stated that the radiator fluids had mixed with the transmission fluids causing the transmission to slip and fail. After hearing this I went online and observed that over 500 people have also experienced the same problem and that it is a defect in the manufacturing of all 2005-2010 trucks and SUV's. I have asked Nissan to repair my car at their expense since it is a problem they knew about. They first stated they did not send me the original info on this problem because they did not know I owned the car. This is not true. They had previously sent me information about a tow bar issue/recall and a Nissan dealer in san jose CA fixed that problem. I believe that Nissan intentionally did not inform owners because they wanted the mileage to exceed what they were offering (80,000). Had I known I would have had my truck looked at long before the mileage expired. What happened to me could happen to a family and if they were to pull into ongoing traffic an accident would certainly occur. This is very dangerous and Nissan needs to do the right thing. I appreciate you opening an investigation on this and hope you get results before someone dies.

Transmission slipped while driving, then would not shift at all. Had to be towed. Transmission was rebuilt, but goes into "limp mode" after a few miles of driving, with a strong odor of hot fluid.

The contact owns a 2005 Nissan Xterra. The contact stated the vehicle started making a rumbling sound after having the oil changed at the dealers. The contact took the vehicle back to the dealer and was told that the transmission was slipping and coolant was leaking from the radiator into the transmission. The vehicle would need both the radiator and the transmission replaced. The failure and current mileages were 85,000.

In March 2011 my wife was driving my son home and the Xterra began to shake as if she was driving on rumble strips. I quickly scheduled an appointment at a Nissan dealer and in anticipation of the scheduled appointment, I googled 2005 Nissan Xterra, rumble strip. Literally dozens of web pages popped up revealing that a defect in the radiator was causing coolant to leak into the transmission, thereby ruining the transmission/radiator. The testimonials detailed my exact experience and also described instances where transmissions would lock-up while driving. I raised my suspicions to cochran Nissan in pittsburgh, PA, and they performed a full service check which confirmed that coolant had leaked into my transmission. Cochran explained that the transmission was salvageable, but that the radiator needed replaced which I later found out had its warranty extended to 80,000 miles. The problem was, however, that my Xterra currently had 101,000 miles, making me a victim of circumstance and the extended warranty of no benefit to me. Cocharan replaced the radiator and flushed the transmission at a cost of approximately $830. 00. Now in February 2013 again as my wife was driving (our two kids), the transmission slipped causing the Xterra to stall and lock up and again I am looking at a substantial repair costing well above the $830 previously paid. Nissan has known about the problem with the radiator/transmission for years (possibly 2007) and has done nothing about it. Damage resulting from a design defect is not something for which preventative maintenance from the owner could rectify. Selling a product with design and/or manufacturing defects to unsuspecting buyers that places persons in danger is unethical and Nissan should be forced to stand by their product and to do the right thing. Please help and protect the consumer.

The contact owns a 2005 Nissan Xterra. The contact stated was driving 30 mph when the transmission slipped.

The radiator initially malfunctioned and caused the failure and the dealer advised replacing the transmission. The contact called the manufacturer yet the manufacturer did not offer any further assistance. The vehicle was not repaired. The failure mileage was 84,000.

The contact owns a 2005 Nissan Xterra. The contact stated the transmission began slipping and the vehicle was taken to the dealer for a diagnosis. The dealer advised that anti-freeze was leaking into the engine because the intake valve gasket was bent. The dealer stated that the valve gasket was bending because the intake valve and radiator were made of plastic. The VIN was unknown. The failure mileage was 86,000 and the current mileage was 95,000.
