  7. Hello friends, I have a 2001 GS300 that has a problem with acceleration hesitation. When it has the problem, I see the traction control warning light flash on the dash for a few seconds. I also hear a "thunk" from the rear of the car. This happens most often when stopped, and especially when facing uphill.
