Electronic stability control: “While this vehicle was not included in the safety reacall bulletin regarding un-intended acceleration, my vehicle no exhibits the issue that, while in motion, the brake and accelerator pedals can be pushed simultaneously, possibly causing a vehicle accident.

NHTSA complaint #10053628, filed 2004-01

Suspension: “I own a 2003 Lexus gs 430 vehicle. During the time that I have owned this vehicle, I continue to experience vibration and brake and wheel wear on the front end assembly. The dealership has aligned the front end and changed tires, but the problem is repeating. I believe that the vehicle is improperly designed either to accept 17 in. Tires or to handle a 4.3 liter engine. The dealership insists that all you have to do is rotate tires every 5,000 miles and there is no problem, but this is not the case. …”
