Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I was reversing and trying to turn when my car Lexus ES 300 suddenly picked up high speed acceleration by it self and went forward and hit a fence in front. The vehicle picked up unintentional high speed (full throttle). It was beyond my control. My body went forward and backward violently. For few days I have experienced muscle stiffness, pain and poor night sleep.”

NHTSA complaint #10627242, filed 2014-08, 135,000 miles

“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”
