Was driving and vehicle transmission stopped moving vehicle. Engine was running and I could see the rpms increase as I gave gas but the drive train stopped working. Had the car towed to a transmission shop. The diagnosed the problem as transmission cooler problem. Explained that it is a common thing with this vehicle. Then discovered through the internet that this has been going on for years and Nissan has not recalled for the defect. Repair shop told me it will be $4500 to repair.

Confirmed diagnoses of vehicle damage of radiator assembly & transmission are due to Nissan's defective radiator assembly which allows coolant to pass through into the transmission rendering the vehicle unsafe to operate. Nissan is unwilling to assist with the repairs of damage caused by defect. I was not notified of this manufacturing defect. This is a safety issue, a damaged transmission due to coolant entering it has rendered the vehicle unsafe to drive, a known defect, yet the manufacturer will not even compromise to assist with repair of this defect. A manufacturer should assist with repair of any defect that renders the equipment unsafe to operate - no matter when that defect decides to show up! Nissan should assist in all repairs due to their known defect to let the consumer operate the vehicle in safety.

My Nissan has the defect that brought a lawsuit against Nissan motor for a failure in the oil cooler that caused my transmission and radiator to be completely rebuilt/replaced because coolant had leaked into my transmission. I ended up with a bill for $3941.46, and now, I can't even file a reimbursement form or get a hold of any one at Nissan to help because all 3 numbers listed in letters and paperwork are no longer in service.

Vehicle had many times failed to gear itself properly causing a sudden jerking motion once gear finally set in. This caused poor acceleration and a check engine light appears. Mechanic says radiator was leaking into the transmission. Radiator was replaced and transmission fluids flushed. Problem still occurs and check engine light keeps appearing. Mechanic says he cannot fix stating the radiator is causing transmission failure somehow and suggests to bring it to the dealership.

I was informed by a friend who has the same make and model car that there is a defect in the radiator that causes radiator fluid to leak into the transmission, thus ruining the transmission. Therefore you need to then replace the transmission.

Driving on freeway at 65mph car started stalling and loosing speed, I stepped on the gas but car would not accelerate. I was a few yards from exit, so I exited and when I reached the bottom of the exit, car stopped and it accelerated in reverse. Very scary and strange. I pulled the emergency brake and turned the engine off even though it seemed to not be running. I towed the car to a mechanic and I found out that the problem was a design flaw in the car that Nissan has acknowledged but did not recall the vehicles. I find myself with a $6,000 repair estimate. I called the dealer after finding out what caused my car to die and they were aware of the problem as well and informed me that Nissan had extended the warranty on the car with a $3,000 co-pay. The problem is not only expensive to repair but a real danger if the car goes into reverse while on heavy, fast traffic. I'm completely aghast that Nissan and the dealers have known about this problem but have not notified car owners nor will they own up to the design defect and repair the vehicles which should not be needing new transmissions with less than 100,000 of driving. I don't know what you do with these complaints, but Nissan needs to do the right thing and repair the vehicles free of charge. The class action lawsuit that they settled is a sham. When we buy cars we expect them to run well, and not have major flaws that would render the cars useless if you don't have the huge amounts of money that it takes to repair them. What does the law allow Nissan to do in this case. They've already ripped us off by selling us faulty vehicles and now they want to rip us off by having us pay for repairs that should not have been incurred to begin with.

Vehicle moving along interstate in heavy traffic at 60 mph when acted as if it was shifted into neutral. Almost got hit twice trying to coast to side of road. There was no response to trying to accelerate, shifter still in D position. Engine temperature rose quickly. Shut engine off engine, to prevent a fire. Sit there momentarily, restarted the engine, temp came down, transmission engaged, drove home. Husband investigated and found oily substance in radiator and transmission low in fluid that was a pasty looking material now on dipstick. Refer to the Nissan radiator defect class action lawsuit settlement case is in re: Nissan radiator/transmission cooler litigation, case no. 10-cv-07493, U.S. district court for the southern district of New York. We were never notified of a recall or the suit, when we would have qualified for assistance from Nissan. Does the state of New York decide reparations to the rest of the country while I am now poor and need a car and can't afford to repair it. How many more failures are out there? includes pathfinder and frontier models. Also discovered VIN number on top of dash was incorrect. Thanks.

My car was running fine and normal but when I tried to start it, nothing happened. I tried to jump the battery and I replaced the starter. After those attempts I had the vehicle towed to a nearby dealership who told me that coolant from the radiator leaked into the transmission and mixed fluid, damaging both the transmission and ECM. Car will not start and the is no communications working. The Nissan dealership recommended I get a new radiator, ipdm module, and transmission which was estimated at a cost of $5,500 after parts and labor. I had the vehicle towed to a local repair shop for a second opinion and was told the same thing as the dealer had said.

- Killeen, TX, USA

Cracked radiator causing coolant to leak into the transmission. Once mixed with the transmission fluid this lethal combination kills the valves, seals and torque converter -- rendering your entire transmission useless. My Xterra is not able to drive. Got quoted over three thousand to repair and my car is not even paid off yet.

Driving down road and car quits steering was difficult hit a curb. The car all of a sudden came back on? has done this to me several times until I parked it now. Dangerous situation. Lucky no vehicles were around me.

Purchased my '05 Nissan Xterra in the spring of 2012 with about 160,000 miles. For the past 2 months I had minor issues like shuddering/vibrations randomly when I accelerated and the heat not working when I was at a complete stop. It was not until the other day when I was at a complete stop and my car would not accelerate properly that I knew I had a problem with the transmission. I took my Xterra to 3 different mechanics and each one explained to me that I would need a completely new transmission and from there they would see if I in fact needed to change the radiator (which they were positive was the original issue due to similar issues with other Nissan SUV owners). The repairs will cost me well over $4,000 and unfortunately as a college student, there is no way I can afford to repair the transmission and radiator. What was appalling to me was when I researched the issue online. There are hundreds upon hundreds of complaints online on various websites about this issue and Nissan has yet to issue a recall. The extended warranty excluded many people and put many more at an unfair disadvantage. I personally bought my Nissan, because of their reputation, but the fact that they will not come to the aid of their consumers speaks volumes of this company.

- Bear, DE, USA

2nd owner of 2005 Nissan Xterra. First had issues with heat not working when at a complete stop, then car would begin to vibrate on the hwy, and now car is having issues up shifting. 2 mechanics have told me the same thing, stating defective radiator was leaking fluid into transmission. Now I must replace both at about $4000. After doing some research online, I have found this is a common issue with this model and Nissan has not issued a recall. Jeopardizing the safety of many and being very costly to those who can not afford a major issue like this.

- Bear, DE, USA

The radiator leaked into the transmission causing the transmission to stop working. I had to have the transmission rebuilt and a whole new radiator system put in my truck. 5300.00.this is a common problem with this model. Tried to send in a claim but was told they are no longer excepting claims because of the problem. If they are aware of the problem then they should help those of us it happened to!!!!!!

Radiator defect causes leakage into transmission. Transmission fails and vehicle abruptly stops unpredictably on the freeway.

- Newport Beach, CA, USA

The contact owns a 2005 Nissan Xterra. The contact stated there was a loud noise in the front of the vehicle intermittently. An authorized dealer was unable to replicate nor diagnose the failure on several occasions. The vehicle was taken back to an authorized dealer again who diagnosed that the timing needed to be reset. The timing was reset and the failure recurred. The vehicle was also leaking fluid; the hood was opened and the cap to the transmission overflow fluid was missing however, the dealer replaced the cap. The contact continued to hear a loud noise intermittently. The vehicle was taken back to an authorized dealer for further inspection and diagnostic testing. The manufacturer was notified of the failure. The approximate failure mileage was 44,000. The current mileage was 65,000.

I was driving on an interstate highway where the speed limit is 70mph. Car begins have a large rumble. Can't tell if it the rear end, the drive shaft or transmission. There is no pattern to the rumble and it continues for several weeks, so I take it to an auto repair shop. They tell me that I have water in my transmission fluid, which was caused by a cracked line in the radiator. I am told to check on the internet, because this is a big problem that lot of Nissan Xterra owners are facing. So, I check it out and the issue is huge. I bought the Xterra about 2 years ago and during that time was never contacted by anyone warning me of this issue. Now, at the time I find that there was a settlement, my vehicle has over the 100,000 mile limit. From what I read, the majority of the vehicles are over the 100,000 mile limit when the problem occurs. My vehicle still will drive and only get the rumble occasionally, but I now know it's fate. It's ashamed that I could not have been warned by Nissan before facing costly repairs. Nissan could have saved us lots of headache and money if we had know and been able to be pro-active before the damage was done.
