One problem related to wiring has been reported for the 1996 Nissan Altima. The most recently reported issues are listed below.
Three times in the last seven months vehicle has accelerated on its own. Nissan could not duplicate this problem. The problem started after transmission was rebuilt, and the radiator, auto transaxle assembly and throttle valve switch were replaced. The transmission was not shifting from second gear to third due to control valve assembly failure. Next, the gas pedal went to floor but the dealer could not duplicate it. However, the dealer replaced the wiring assembly. The problem still exists.
