2003 Toyota Corolla ProblemsCheck Engine Light Due to EVAP System Fault
The Check Engine Light may illuminate due to an evaporative emission (EVAP) system fault. Our technicians tell us these EVAP system faults can be difficult to diagnose but it is not uncommon to find a failed charcoal canister or a loose or worn gas cap.
If the engine will not crank over, the most common problem is the starter. These will tend to go out at about 100,00-125,000 miles. Sometimes it is only the starter solenoid, but often the complete starter (including solenoid) needs to be replaced.
At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.

2003 Toyota Corolla RecallsSeat Heater Wiring Shorts And Causes Fire
For vehicles equipped with aftermarket accessory seat heaters, the seat heater elements may short circuit when the seat cushion is compressed, and result in a fire hazard. Dealers will disconnect the seat heaters and refund the purchase price of the seat heaters free of charge to resolve the concern,
The airbag control module can fail prematurely due to electrical noise beyond the tolerance it was designed for. As a result the front airbags, side airbags, and/or seatbelt pretensioners could deploy inadvertently while the vehicle is being operated, increasing the risk of personal injury and/or a crash. Dealers will replace the airbag control module and front and/or side impact sensors as required to correct this concern.
This limited regional recall is for vehicles currently registered or first sold in southern Florida, along the Gulf Coast, Puerto Rico, Hawaii, the U.S. Virgin Islands, Guam, Saipan and American Samoa. Upon deployment the passenger airbag inflator could rupture, increasing the risk of personal injury. Dealers will replace the passenger side air bag inflator to correct this concern. If a replacement inflator is not available, as an interim measure, the dealer will disable the front passenger air bag and advise the customer not to use the front passenger seat until a replacement inflator is installed.
