2003 Lexus GX 470 Owner Comments

GX 470

  • 93,031 miles


I own a 2003 Lexus GX470. On Friday January 8th as I waited for traffic to clear before turning right to enter a blvd, the engine suddenly began to race while my right foot forced down the brake pedal to prevent the car from "launching" into the cross traffic. The vehicle began to shudder and shake and my dad yelled "you're spinning your tires!" I yelled "my foot is on the brake, what should I do"" we turned off the ignition and the engine stopped running. Later, while my dad observed from the open driver's-side door, I roughly trumped on the gas pedal 2 or 3 times because we were vaguely aware of a Toyota "accelerator sticking" problem. I then started the car and drove it several miles - while totally terrified. Immediately I arranged to have the car transported to my dealer's facilities. And, after three days of "testing, " no problem was found and I drove home, shaking. So, judging from recent media reports, what was new or different about my experience" 1) no mats were ever used in the driver's compartment during the five years I have owned the car. 2) the engine was "at idle" and the brake pedal was depressed before the engine began to suddenly race. 3) I am not a "two-foot" driver...never, ever. 4) my dad checked (yes, he is a mechanical engineer) to see if the gas pedal was in its correct idle position after shut-off: The petal position was normal, normal before, during and after being "trumped" on. 5) my car was not moving, just waiting, at idle, with no operator intervention prior or during engine rev-up. In a nut-shell, my near-death experience could not have been provoked by a mechanical problem with the accelerator petal. This failure has not happened again... no repair was made... my dealer claimed that nothing like this has happened on a Lexus that they knew about...but congressional testimony today shows that other Lexus owners have experienced sudden engine acceleration with no pedal involvement.
