GS 300 6-cyl

Engine check, vsc and vsc out lights remain on after auto is started. Replaced fuel fill cap..no help. Very concerned about fuel or fume leakage and life threatening fires or explosions.

GS 300

  • 6,000 miles
2004 Lexus gs 300 has repeated problems with accelerator when pulling out from a stop or attempting to increase speed. After pushing on pedal the car begins to move then stops accelerating. Then surges as pedal continues to be pressed down. I have reported the problem several times to dealership only to be told that Toyota is aware of the problem but there is no resolution after 5 years. Several times I have attempted to pull out from a stop sign as one normally would then forced to push the accelerator to the floor in an attempt to get the vehicle moving to avoid an accident. This is a repeating event and I am forced to pull the EFI fuse every 5000 miles which seems to reduce the effect temporarily. Lexus is/has been aware of this problem since there was 6K miles on the vehicle which now has 60K miles and is out of warranty. I am overly cautious and fearful when driving the vehicle. If I need to accelerate to merge into traffic or just normal driving, the vehicle will not respond by accelerating. And I'm also concerned if this is an early symptom that Toyota is having with runaway vehicle acceleration. The Lexus dealership attributed the problem to the ECM and drive by wire mechanism Toyota has employed in this vehicle.

I had my gas pedal stick twice on my Lexus gs 300 year 2004. The first time I didn't know what was going on. I was in my driveway when it happen and I put my foot on the brake and shifted into nuetral. The second time it happened I noticed the factory floor mat was jammed into the gas pedal. Both times I was able to apply the brakes to hold the vehicle in place and shift to neutral. Reported this to the dealer but they claimed they had no reports of gas pedal sticking for the gs 300.
