Lexus GS350 VGRS failure due to power steering rack malfunction on Lexus GS350

Some Lexus GS350 owners report experiencing issues with VGRS (Variable Gear Ratio Steering) failure, which may be linked to intermittent power steering malfunctions. These problems can lead to an off-centered steering wheel, particularly in early 2013 model year GS 350 F-Sport RWD vehicles when restarted immediately after parking with the wheel turned. Additionally, owners may find that a malfunctioning power steering rack, a critical component of the steering system, may need replacement as diagnosed by a dealer. However, VGRS failures are often more closely related to the Steering ECU, especially when fast steering movements occur during parking. It is crucial for owners to ensure the power steering rack is functioning correctly to avoid inaccuracies in steering wheel position, highlighting the importance of proper maintenance and timely repairs for safe vehicle operation.
