Recalls

2 vehicle recalls from the manufacturer, plus 1 equipment/tire recall that can apply. Repairs are free. Check your VIN to see if one is still open on your car.

Electrical Vehicle recall #98V278000 · 1998 · 1,960 vehicles

What's wrong: In the states of alabama, florida, georgia, north and south carolina. The alarm wiring harness plugs into the vehicle's ignition switch and the vehicle's ignition switch wiring harness plugs into the alarm harness to complete the circuit. A percentage of the female terminals used in the alarm connector were found to be defective, causing an 'open circuit' condition when mated to the male ignition switch terminals.

Why it matters: This condition can cause intermittent performance of the vehicle's electrical components such as the dash warning lights and/or HVAC fan speed controls. Also, the vehicle May not run smoothly and could stall.

The fix: Dealers will inspect the date code label on the security system harness and any displaying the manufacturing/final date code will be replaced with newly produced harnesses. The date codes are: rav4 - 6/24/98, 6/25/98, 6/26/98; sienna - 6/25/98, 6/26/98; and avalon - 6/30/98, 7/1/98, 8/31/98,…

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.…
