One problem related to wiring has been reported for the 2005 Toyota Matrix. The most recently reported issues are listed below.
The air bag warning light remains on while the car is on. I was told the air bag would not function properly while the warning light is on. The Toyota dealer said the air bag wiring is shorting in the clock mechanism and clock parts need to be replaced for the air bag to work. Why do I need to fix the clock for this air bag to work?.
