Steering Wheel May Become Off-Center
Suspension & Steering, July 12, 2010
RepairPal Expert Overview
Our Quick Take:
A problem with the steering control system may allow the steering wheel to become off-center after the driver has fully turned the wheel in one direction. If this happens while driving, the risk of a crash is increased.
What Should You Do?
We at RepairPal have designated this a high priority recall; the steering wheel may go off center without warning. Please contact your Lexus dealer. They will check to see if your specific vehicle is affected and advise you on what to do next. Always have your vehicle identification number (VIN) handy when you call.
A programming change to the variable gear ratio steering (VGRS) system can cause improper activation of the steering system protection logic, which is designed to protect the steering system when larger than normal inputs are applied when the wheel is fully turned. Improper activation of the protection system can cause the steering wheel to become off centered up to 90 degrees. This can happen if the steering wheel is fully turned and then quickly turned back to center. If the steering wheel unexpectedly becomes off center while driving, the risk of a crash is increased. Dealers will replace the steering control ECU free of charge. The recall began on July 12, 2010.
