2003 Toyota Avalon Problems
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 Recalls
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.

Owned Camry's up until this one. I love the conformable ride and so do our friends. Only problem, master cylinder went @ 108,200. All in all the car has been great. Just remember your service check-up, its been a fantastic car for us.
