After 2 and a half months of fighting with Nissan Consumer Affairs, Nissan has basically told me they do not care about me or the other people affected by this issue or their safety. As sad as it sounds its going to take someone getting killed because of this issue before they open their eyes.

Timing chain on 2005 Nissan Frontier. The engine makes a loud whining noise due to the chain contact. When the vehicle is stationary or motion it make the noise. When the vehicle in motion it changes gears at a higher RPM. I have sensors that were operable because of the timing chain issue.

On my truck I experienced a sudden loss in power and throttle response while driving without warning, as the transmission failed to shift gears properly. After spending $100 for a diagnostic from a mechanic it was found that my transmission cooler reservoir is leaking in my radiator and caused cross contamination between my antifreeze and atf. The antifreeze is getting into my transmission and boiling once the transmission reaches operating temperatures. The antifreeze vapor is then causing the transmission clutches and bands to not be able to engage correctly, and therefore not being able to shift up and down through the gears properly. I just about got hit trying to turn left out onto the road in front of cross traffic. I avoided an accident, but this happened with no warning. This fix is going to cost me anywhere from $500 to $5,000 to fix depending on the extent of the damage the antifreeze in my transmission caused. I just read that a few years ago Nissan extended the warranty due to this, and I am past that point, but this is still unacceptable at only 102,000 miles. Nissan should have recalled this and fixed it when it was just a couple hundred dollars for a new radiator years ago. Lastly, my truck without issues was worth nearly $8K in its condition, now I'll have trouble getting a dealer to pay anything in trade-in value if I choose to not fix the truck.

I was driving on kingery highway in villa park when I stopped for traffic. When I tried to accelerate after the traffic was moving, the lights on the dashboard turned on and the truck would only accelerate to less than 1 mph. This could have caused a serious accident.

My 2005 Nissan Frontier has a problem with the radiator that allows coolant to enter the transmission which is causing major damage to the interior parts of the transmission causing it to not shift through the gears. Nissan is only willing to extend the warranty to 100,000 miles and $3000 for the repairs of their defective products.

While traveling on the #1 lane at approximately 70mph on the 60 East freeway close to the intersection of the 57 North freeway connector, I lost full power and was forced to make an emergency exit narrowly missing several trucks and cars in the process. After limping home and letting the vehicle sit for a few days, I took the truck to puente hills Nissan complaining that I lose power once the transmission comes to temperature and that I needed them to asses the damage at a cost to me of $130. Their evaluation eventually concluded that the radiator had ruptured causing coolant to leak into the transmission thereby damaging it beyond repair. They quoted me approximately $4,500 for the repair which mainly included labor, tax, a replacement transmission, a new radiator, and all necessary hoses and parts. I was able to drive the vehicle but approximately 1.5 miles from my home, I lost power once again and was forced to have the vehicle towed the rest of the way. The vehicle is no longer safe to drive at all at this point.

Nissan has a know radiator problem. Internal leakage into the transmission cooler. Causes catastrophic transmission failure. Pulling away from stop sign. Transmission shifted hard twice. Then had no forward motion, engine would rev up, but not move the vehical. Truck has 100,000 mile Nissan extended powertrain warranty. Was first told by the dealer. 100% covered. Less than an hour later, was told not covered. Cost $5000 plus. Contacted Nissan customer service. Gabby at Nissan siad they would look into it. Took a week for them to finally call back. They asked me to cover $2000. They would not cover the whole bill, even though it is a known defect. And the truck has the extended warranty. I paid $2192.43 to have the transmission and defective radiator replaced. Asked if the radiator was an updated part. Waiting on a call to find out if it is a better radiator or just a new one with the same defect. Right now. Its a ticking time bomb, if the failure occured in traffic on an interstate, a major crash could have happened.
