The transmission cannot be downshifted. I was towing a large boat and limited to 10mph speed and was unable to downshift the engine.
While performing a tire rotation, it was noticed that the passenger side rear axle seal was leaking.
I had an accident in my 2006 Nissan Titan in July 08. I was pulling into a parking spot when the engine roared the truck quickly moved forward and I was unable to stop the truck. The only thing that stopped the truck was a cement spindle fence. I destroyed 10 feet of fence and my insurance had to pay for the damages. I took the truck to Nissan and they checked it, but they stated they were unable to duplicate the problem, they then performed the 30000 mile maintenance for approx $600. The Nissan service person told me that I must have pushed the gas and the brake at the same time to cause the accident. I then took the truck to an open field and pushed the brake and the gas pedal at the same time and the tires just spun and the truck did not move. I tried the same thing in an empty parking lot, the tires spun and the truck did not move. I ended up getting rid of the truck because I was afraid if the truck sped forward on its own again and I could not stop it I might get hurt or killed. I believe that there is some type of defect that caused the engine to roar and cause the truck to speed forward. I filed a police/accident report with the local police.
Truck became stuck in a muddy ditch, used 4 wheel drive to get out of the ditch. After pulling out of ditch truck was turned off with truck in 4 wheel drive. In an attempt to get out of the ditch the truck did spin, but not excessively. When truck was restarted, there was a warning on the instrument panel. Truck would not go forward, but would go in reverse. Had truck towed to dealership for repair. Although the truck is still under complete warranty, the dealer refused to repair the transmission under warranty stating that the transmission was burned up and that the truck had been abused because there was mud on the truck.
