2003 Toyota Avalon ProblemsMisfire and/or Check Engine Light Due to Failed Ignition Coil
On higher mileage vehicles, an engine misfire may develop and/or the Check Engine Light may illuminate due to a failed ignition coil. It is not uncommon to replace all the coils when the first one fails in order to prevent return trips to the repair shop.
The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.

2003 Toyota Avalon RecallsUnexpected Airbag Deployment
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.
Circuits in the supplemental restraint system may short, resulting in damage that may unintentionally deploy the front air bags and / or seat belt pretensioners. Dealers will install a noise filter between the air bag control module and the affected wiring harness free of charge to resolve the concern.
Toyota is recalling 2000–2004 Avalon models due to improper casting of the steering lock bar, which may cause the bar to crack or even break. If the bar breaks, the steering wheel will lock, causing the driver to lose control of the vehicle, increasing the risk of a crash. Dealers will replace the steering lock device free of charge.
