RepairPal Expert Overview
Due to a software fault in the power steering computer, the steering wheel may become crooked after starting the vehicle.
Toyota will notify owners of affected vehicles beginning in early June, 2012. If you are experiencing problems with the steering wheel staying "on-center," or you don't receive notification and you feel you should have, please contact your dealer. It’s helpful to have your vehicle identification number (VIN) handy when you call.
The variable gear ratio steering (VGRS) steering system in these cars is controlled by a mico processor. The processor (Electronic Control Unit - ECU) programming for this system could cause the steering wheel to become "off-center" when restarting immediately after the vehicle is parked with the steering wheel turned. If this occurs, the vehicle could move in an unexpected direction, possibly resulting in a crash. Dealers will update the VGRS system to correct this concern.
