What 2003 Lexus GS owners say
Most recent owner complaints, unedited.
Acceleration pedal problem. Car fails to respond to acceleration pedal sometimes while in motion. Car can stop moving in traffic or during turns (especially left turns). This is very dangerous and life threatening. Although pedal sensor was changed given the error code, the car still show the same issue. Lexus must take responsibility for dangerous design as it lacks a fail safe mechanism to their drive by wire. Failure in acceleration is as dangerous as failure in braking.
When backing into a parking space with my foot on the brake, the rpms surged causing speed to increase suddenly. I place the car in neutral and the rpms continued to surge for about three seconds and then returned to normal. While waiting at a traffic signal, with my foot on the brake, the rpms suddenly surged and I again placed the car in neutral. The surge continued for about three seconds again. On one other occasion, when shifting from reverse to drive while exiting a parking space, the rpms surged for about two seconds and then returned to normal. The vehicle seems to accelerate suddenly on its own without depressing the gas pedal.
I own a 2003 lexus gs and all four rims are chrome and have become a safety hazard according to where we have our service. I own another lexus auto and my rims are in good shape . I have never experience rims chrome plate pealing causing newer tires to lose air before. I was interested to find out if any other owners have or are experiencing the same problem with this models rims. Thanks
