2012 Toyota Corolla Problems

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.

Engine Won't Crank Due To Starter

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.

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.

Vehicles With Added Seat Accessories May Not Have Properly Functioning Restraint Systems

Vehicles that have had accessories added to the seats such as seat heaters, seat covers or DVD headrests may not have the occupant sensor system of the passenger seat calibrated properly. This can affect passenger air bag operation in a crash. Dealers will test the sensitivity of the occupant detection sensors and recalibrate them as necessary free of charge to resolve the concern.
