While driving, without warning the vehicle cut off, losing all power including braking power, nearly causing an accident. After multiple shops inspected the vehicle it was discovered that coolant had entered the transmission through a well known failure. This failure causing coolant to enter the transmission destroyed the transmission. This failure is also documented through a class actions lawsuit as well as hundreds of similar claims found online.

The transmission stopped working while driving on the highway. I have read other complaints on this issue, so disappointed this has not been a recall. I just missed getting hit from behind due to the sudden stop.

Exiting parking lot, vehicle experienced sudden, "accute" out of control - acceleration. Immediately depressed brake pedal, yet Xterra continued forward some 40 - 50 feet unimpeded, in a severe bucking fashion. Fortunately no person, nor object was in my path. Contacted Nissan North America, was directed to take SUV to local dealer (vallejo Nissan) for inspection. Computer analysis displayed no mechanical issues. There are without a doubt, critical flaws, just waiting to be unleashed on an unsuspecting public. Nissan has staunchly refused any further evaluation.your assistance would be appreciated. Thanks so much.

Radiator coolant leaked into transmission and now I need a new transmission and do not have the money for this repair. There needs to be a class action lawsuit as this is happening to Nissan owners after the warranty has expired and Nissan knows about this. I was driving down the main street and vehicle service light came on and then I could only go about 10-15 mph because of the transmission

5 months ago the transmission fluid leaked into the radiator causing antifreeze and transmission fluid to mix now the transmission has gone out because of this caused be to be stuck on the road I now need a new transmission.

The contact owns a 2007 Nissan Xterra. The contact stated that while attempting to shift, the vehicle started to shake violently. After inspecting the vehicle, the contact noticed that the radiator was leaking coolant into the transmission. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 146,000.

Left my house garage and suddenly I notices that the car was loosing the power, so I went back to the house after few miles driving. And next morning, I was going to take my car to the mechanic, the engine didn't start. So I called to tow my car to the mechanic. According to the mechanic, car wouldn't be function due to the transmissmission and computer failure. My car is still in the shop, so I dont know the exact odometer.

Transmission slipped and couldn't accelerate, my 16 year old daughter was driving, about ran over by trailer. Researched and found out this is a known problem that Nissan isn't taking care of.

- Hoschton, GA, USA

The engine coolant leaked into the radiator and the transmission and radiator are ruined. I am a single mom raising 2 kids trying to save money to get it fixed. I have seen several complaints on this exact problem.

Transmission over heats due to radiator hose corrosion.

- Highlands, TX, USA

The contact owns a 2007 Nissan Xterra. While driving at 45 mph, there was a grinding noise coming from the front of the vehicle. In addition, the contact felt a vibration in the steering wheel and the accelerator pedal. The vehicle was taken to an independent mechanic who stated that there was a cross contamination of coolant between the engine and the transmission. The mechanic diagnosed that the transmission needed to be replaced. The vehicle was not repaired. The vehicle was taken to a dealer where it was confirmed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 70,000.

A hesitation in the vehicle's acceleration began occurring frequently upon depressing the accelerator after a full stop at a stop sign or red light, but not at any other time in driving the vehicle. The problem was first noted when departing the dealership after which a new timing chain had been replaced. When reviewed by the dealership upon return to the service area (another appointment had been made at later time), a loss of over one quart of transmission fluid was detected (over what time period was unclear), but no known source of external leakage was found. This led to the conclusion that internal leakage was very likely occurring. Due to the many instances of radiator cracks and toxic mixing of fluids among similar year models (mid-2000 model years of Nissan Xterra), the dealership recommended that the radiator be replaced and the transmission thoroughly flushed, which might prevent the transmission from requiring a complete overhaul in the future - although there are no guarantees. This work was completed for a total of $1500 including discount; the incident occurred well after the extended warranty provided by the manufacturer for resolving issues that had been experienced by others, hence the dealership's charges. A request was nonetheless made to get reimbursed by the manufacturer (Nissan), currently under review. It is possible that this issue was dealt with at a very early stage and might therefore result in a lower probability of transmission problems in the future, which could cost several thousand dollars ($6-7,000 or more). Other drivers/owners have typically experienced more severe issues, such as shaking/stalling vehicles and/or illuminated dashboard lights indicating engine problems.

Transmission has coolant in it due to a Nissan known problem. Transmission line goes into bottom of radiator develops a crank inside and leaks coolant into the transmission resulting in transmission failure.

- Virginia Beach, VA, USA

The contact owns a 2007 Nissan Xterra. The contact stated that there was transmission failure and there was a component that fractured without warning, associated with fluid leaking from the radiator into the transmission. The vehicle was taken to an authorized dealer who diagnosed that the transmission and the radiator needed to be replaced due to a crack in the atf line that flows through the engine coolant chamber into the radiator. The vehicle was not repaired. The vehicle was not included in NHTSA action number: DP12004 (power train). The manufacturer was notified of the failure. The failure mileage was not available.

Water from the radiator got into the transmission and I had Nissan replace transmission and radiator at the cost of $4700 dollars when they should have had a recall bad business.

- Rockholds, KY, USA

Our 2007 Xterra at 87,000 miles left my wife and 2 kids stranded on the road with a destroyed transmission due to a defect in the radiator cooling lines that support cooling the transmission. The coolant mixed with the transmission fluid and the resulting pressure caused the radiator pressure cap to blow when the engine overheated. This strawberry milkshake looking fluid leaked all over the ground and was difficult to clean-up this is a known Nissan defect issue and should be a recall before someone get hurt or further environmental pollution results.

I had brought the Xterra to the mechanic on May 4th for intermittent vibrations ( which I attributed to the rough roads S/P winter as it occurred at the same points on the same roads ) over 2 month and a new intermittent thumping noise heard when the vehicle was shifting gears in the last 2 weeks. Nothing came up on the computer system showing any issues other than the known alert for the gas level part that shift the bed 6 months ago and I refuse to pay $400 for a $40 part that should have lasted the lifetime of the vehicle, ( another issue Nissan is aware of as it comes up on the computer to the mechanic that this a known defect but won't replace it free of charge) end result, transmission fluid and radiator fluid were mixing due to a known issue by Nissan and defective parts. There is no recall. The radiator and transmission cooler needed to be replaced costing over $1600. I have read on complaint websites regarding this known issue and I am aware this cost is much less than what other Nissan owners have paid as some customers have needed to replace their transmissions or have needed to junk their vehicles as Nissan refuses to take responsibility and suck up the cost to fix this significant mechanical problem on their vehicles !!!!!

The radiator used in my 2007 Nissan Xterra is a faulty product which caused a leak of the radiator fluid into the transmission fluid system. When the transmission heats up during longer periods of driving, the radiator fluid also heats up and effectively ruins the internal transmission parts. This has caused several issues in the shifting of the vehicle, and often times in very dangerous situations where acceleration is key to avoiding accidents.
