When the vehicle is parked with the steering wheel turned, the calibration of the ECU for the Variable Gear Ratio Steering can cause the steering wheel to "become off-centered" if the car is immediately restarted.
Lexus will be notifying owners in early June, at which time they can take their cars to the dealer to have the ECU recalibrated free of charge. Scroll down for the press release.
On May 16, 2012, Lexus filed a Defect Information Report (DIR) with the National Highway Traffic Safety Administration indicating it will conduct a voluntary safety recall of approximately 650 – early 2013 model year GS 350 F Sport Rear Wheel Drive (RWD) vehicles to update the Variable Gear Ratio Steering (VGRS) electronic control unit (ECU) calibration.
On certain early 2013 model year GS 350 F-Sport RWD vehicles, the ECU for the VGRS system could cause the steering wheel to become off-centered when restarting the vehicle immediately after the vehicle is parked with the steering wheel turned. Dealers will update the VGRS ECU calibration to address the condition.
Owners of the involved vehicles will receive a safety recall notification by first-class mail beginning in early June 2012.
Any authorized Lexus dealer will perform this update at no charge to the vehicle owner. The repair is expected to take approximately 30 minutes depending on the dealer's schedule.
No other Toyota or Lexus models are covered by this safety recall.
