Recalls

1 vehicle recall from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.

Body & structure Vehicle recall #10V160000 · 2010 · 600,000 vehicles

What's wrong: The subject vehicles are equipped with the spare tire stowed under the vehicle. If the vehicle is operated in the cold climate regions of the united states where road salt is frequently used, water splashed backwards with high concentrations of road salt can reach the spare tire carrier and corrode the spare tire carrier assembly cable.

Why it matters: The cable May break due to excessive corrosion and the spare tire May separate from the vehicle, possibly resulting in a vehicle crash.

The fix: Toyota will notify owners with an interim letter initially instructing them to bring their vehicle to authorized dealers to inspect for corrosion. A second notice will be sent when the permanent remedy is available. For more information, please see Toyota's amended recall report of July 19, 2010.…
