Three problems related to warning light on have been reported for the 1999 Toyota Avalon. The most recently reported issues are listed below.
My air bag warning light has come on frequently while driving. The owners manual states to take it to the dealer immediately. Once there, the dealer states there is no code stored in the computer and there is nothing they can do. Once the car is restarted, the light is off, but comes on again a few days later. This has happened numerous times. I am worried of an air bag failure due to this indicator light, but the dealer can't help because of the lack of stored codes.
While driving along air bag warning lights came on. Sometimes air bag warning light flashed on and off. Sometimes the light would stay on. Vehicle was taken back to the dealership twice. Dealer stated that the entire air bag computer system was replaced. Problem still exist with the air bag.
Air bag warning light illuminates, indicating a malfunction within the air bag system. Cause unknown. Dealer can not identify the cause of the problem. Please give any further details.
