The contact owns a 2008 Nissan Altima. The contact stated the accelerator pedal was stuck in the up position while depressing the pedal, the vehicle failed to move. The vehicle was taken to the dealer where they performed a diagnostic test but could not duplicate the failure. They also reprogrammed the computer but the problem continued. The manufacturer was not contacted. The failure mileage was 10,000. The dealer replaced the throttle lever assembly. Updated 11/05/10 the consumer stated as he backed out of the driveway, he then put the gear in drive and the vehicle would not move beyond 5 mph. After about 100 feet of a slow roll and trying to engage the accelerator, it caught with a lurch. According to the dealer, the transmission was overfilled with fluid, which caused the vehicle to shut down. Updated 12/22/jb.
2008 Altima 2. 5s was on 35-35 degree incline with front facing uphill. As I was exiting the vehicle, it popped out of park and into neutral. Before I could stop it, the driver door caught on neighboring yard/hill and bent forward. Damage to rear bumper as well. Damage totaled approximately $3700. Nissan said their filed tech could find nothing wrong with the car. I have found 7 other instances of this happening but they did not seem to care. This car is not safe to drive or park for that matter.
2008 Nissan Altima 2. 5 4 cylinder with cvt transmission, when pulling out on highway the car began to accelerate normally at first (0 to 25 mph) but then would not accelerate and coasted into traffic nearly causing accident. This happened twice more on the way to the dealership. The problem happens intermittently and has been reported to a Nissan dealer twice for repair under warranty. Check engine light came on when lack of acceleration happened 3 times and twice the dealer reset the code, change the fluid and reprogram the computer and said it was just a fluke and that it found no hardware problems. The Nissan cvt transmission control electronics are unreliable, unsafe and should be investigated. This recurring problem very nearly resulted in a major accident today.
