2003 Toyota RAV4 Problems

Software update to correct false catalytic converter failure

Toyota released a software update to fix a problem that caused the Check Engine Light to come on. Before the update, the computer would report a problem with the catalytic converter when there wasn't one.

Automatic Transmission May Not Shift Correctly at High Mileages

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.

Check Engine Light on Due to EVAP Vapor Canister Fault

The Evaporative system may have problems with the vapor canister releasing charcoal pellets that plug the vent valve. Typically a Code P0441, P0442 and P0446 will be set. The key code is the P0446 which is a vent valve electrical failure. The proper repair is to replace the entire canister with all the valves as a unit. This is located on top of the fuel tank and is expensive. Our Technicians tell us that for awhile Toyota was covering these problems, but this may have changed. It would not hurt to call the dealer if this problem occurs to see if Toyota is still helping with these repairs.

2003 Toyota RAV4 Reviews

260,000 miles and i have only done routine maintinance
I bought my Toyota RAV4 back in 2003. This has been an efficient commuter vehicle as well as a comfortable ride for long trips to South California. With its regular maintenance; oil and air filter changes, brakes and battery, no major repairs after more than 100,000 miles. One detail is that both front door motors actuators broke down one after the other.
