1. The vehicle hesitates with initial acceleration (slow or quick acceleration). 2. The automatic transmission also hesitates. I suspect that ounce the acceleration problem is fixed that the transmission problem would be fixed. 3. I have gone to the Lexus dealer to update the computer with a new chip to help resolve the problems with no success. 4. I have discovered on the internet that hundreds of Lexus owners have the same complaint. In some cases the dealers have the audacity to suggest thats the way the car was designed! why isn't Lexus listening to all the complaints? thanks.
