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.

My car oveheated and began to buck -- mechanic stated transmission and radiator have failed - I still owe 1 year on this car and Nissan wont fix it - can you help in any way published on Apr 18, 2013 video of what happens to the radiator/transmission fluid when the transmission fluid radiator fails and a cross connection happens between the two fluids that don't belong together. Nissan settled a class action lawsuit in January of 2013, but this doesn't mean that you still can't file a complaint with the national transportation safety administration. If you have experienced this problem or no someone that has, file the complaint. Also call the state attorney general and the federal trade commission and file a complaint against Nissan. We bought the car used, but there is no way to check for this problem. If we had known the problem existed, I assure you we would not have purchased the vehicle. If I knew there was a potential problem after we purchased the vehicle, we could have replaced the transmission coolant radiator with the safer replacement type to prevent this from happening. I think it should have been the federal government's responsibility to notify the public of the problem and they should force Nissan to address the issue. They made Toyota step up with recalls and Toyota did to my recollection. Should have purchased a Toyota.

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 purchased a brand new 2005 Xterra 1/2006 with 10 miles!!!! I paid 28,000 for this vehicle and worst vehicle I never had!!! I only service this vehicle at the dealership!!!! I had so many issues with this new truck!! the check engine light keeping on at from the very beginning and when I took it to the dealership said nothing was wrong! over time, this was a complete lemon!! the vehicle had to replace a radio, 6 batteries, 3 alternators, hoses leaking, oil leaking within 3 years purchasing a new truck, fuel sensor replaced, fuel pump replaced, 1 cal.conventor replaced, and worst of all transmission issues!! the truck will not go up hills and when I took it to 2 different places said that the radiator was leaking into the transmission and Nissan knew about this and never said nothing!!!!!!!!!!!!!!!! I only took my truck to the dealership and they never said a thing! I could replaced the radiator long time again to avoid the transmission going out!! 5,500 repair job!!!!!!!!!!!!!! this is poor quality truck with all the issues I had since I brought it brand new !! my Acura have 241,000 and never had any of these issues that I purchased used!! I contact the Corp office and they will never do anything! the Nissan dealerships around the country knows the issues with these Nissan cars and never say a thing!! I will never purchase a another Nissan!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! they will not stand behind their product!! 4 of my friends with Nissan (Xterra, pathfinder, and maxima) the transmission went out within 6 months of each other!!!

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.

We have a 2005 Nissan Xterra and were never told about the trouble with this models trouble with the radiator coolant leaking into the transmission and causing damage. Nissan extended their warranty with a deductible up to 100,000 miles and ours leaked at 106,000 miles causing $5600 in damages that Nissan refused to acknowledge. Had there been a recall this never would have happened.

- Clearwater, FL, USA

My 2005 Nissan Xterra transmission went out as I was driving across the causeway and almost ended up in the marsh. I searched online and this is a common problem with the radiator leaking into the transmission. Nissan was involved in a class action lawsuit but it's to late for damages. I think this is a safety issue and Nissan should have recalled these vehicles before someone is killed.

- St Simons Island, GA, USA

Transmission failure due to defective valve unit. Very dangerous situation as the vehicle loose complete power. This is happening to a lot of Nissan Xterra 2005 owners.

- Hollister, CA, USA

The class action lawsuit that is going on, this is what happened to my vehicle. My coolant leaked into my transmission, now my transmission is now destroyed as well as my radiator, and the estimates are $5500 to fix. I almost crashed and got hit by an 18 wheeler when this happened, I need to report this because I hope Nissan steps up and fixes this once and for all, instead of letting there customers hang out to dry.

The contact owns a 2005 Nissan Xterra. While driving approximately 40 mph, the vehicle decelerated and the rpms increased without warning. The vehicle was towed to an independent mechanic. The technician diagnosed that the transmission oil cooler failed and caused water to enter into the transmission. The transmission needed to be replaced. The vehicle was repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 102,000.

- New Orleans, LA, USA

Unexpectedly, transmission seemed to be in neutral. Applying gas just revved engine. Then strong jerk and back into gear. Happening at highway speeds on a busy interstate had it gone on longer or I not been able to pull to the side, this could have triggered a major pile up.

- Fairfax, VA, USA

Bought my 2005 Nissan Xterra brand new and it now needs a new transmission because of a radiator leak. After doing some research I see that there are thousands of them with the same problem yet no recall and Nissan is not willing to do anything!

- Madison, FL, USA

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.

The transmission shakes violently on acceleration. So I drove the vehicle to the dealership for a diagnosis. I have learned that the radiator cracking and leaking into the transmission is a common problem for the 2005 Nissan Xterra, and that Nissan settled a lawsuit in October of 2012. I do not remember getting any information that this might be a problem and I have to pay $3000 to get the transmission and radiator replaced! after 100,000 miles I am stuck to pay the complete cost of the repairs. Is there any kind of recourse for this problem that I am unaware of?

- Rochester, MN, USA

The engine started to overheat and the vehicle transmission started to shift irratically. There was an oily substance in the coolant reservoir. I contacted the dealership and was told that this is a known condition requiring replacement of the radiator and rebuilding of the transmission. I was told that since there was 101000 miles on the vehicle, that the entire $3800 for repair would have to be borne by me. I tried driiving the vehicle several times afterwards with the same result. It has been parked in front of my house for 6 months now as I don't have the money to repair.

- New Orleans, LA, USA

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.
