The contact owns a 2004 Nissan Altima. While driving various speeds and while the vehicle was stationary, the vehicle stalled without warning. Several independent mechanics were made aware of the failure and replaced the manifold, oxygen sensor, and a computer chip; however, the failure recurred. The dealer and manufacturers were not made aware of the failures. The failure mileage was 1,361.
The vehicle kept showing codes p1148, p1278 and p1279. Took it to Nissan dealer several times and they changed maf sensor, all oxygen sensors, fuel system cleaning but the code kept showing up. The vehicle finally shut off on the parkway without warning and we were rear ended. Luckily we were only two in the front of the vehicle and had to be taken to the hospital. We both have suffered serious injuries from this accident. The Nissan Altima is a death trap. Nissans is a bad company. . . . Beware!!!.
"engine service soon light" came on and took car to the shop on 10/31/06. At the time it came on there were no running problems. Nissan dealer replaced rear 02 sensor and diagnoses and reprogrammed engine control module. On 11/20/06 (less than three weeks later) the "engine service soon light" came on again. Prior to taking the car there were no running problems. Nissan dealer checked vehicle and called me and said that they need to run another diagnostic test for another fee. When I went to the dealership the vehicle was idling up an down and would accelerate on its own without touching the accelerator. P2135 throttle position sensor found, replaced sensor and cleared codes. I was charged on both occasions for a total of $668.
