Two problems related to cruise control have been reported for the 2005 Lexus ES330. The most recently reported issues are listed below.
On Dec. 9, 2006, our '05 Lexus Es330 accelerated spontaneously in reverse down our (fortunately long) driveway. Braking did not stop the car. In fact, the tires squealed loudly as I braked. I put the car into neutral in order to stop it. We immediately took the car to a Lexus repair shop. They, of course, could find nothing wrong. They mentioned having received some reports of floor-mat problems causing acceleration, but couldn't tell me more. The floor-mat on this Lexus was fixed, so that wasn't the problem. This incident only happened one time. I thought the problem was related to the cruise control, because my brother-in-law had a similar problem (going forward though) that was diagnosed as the cruise control causing acceleration. Even though Lexus said my cruise control checked o. K. , I never used it again. We decided to sell the car, & did so within 6 months.
2005 Lexus Es330 with sudden acceleration. Consumer stated on two incidents her vehicle rapidly accelerated. In one incident there was an accident. The consumer stated if felt as though the cruise control had activated and the vehicle suddenly lurched forward and took off from a parking lot, down a slope, into traffic and into an oncoming car. The dealership inspected the vehicle and the consumer was told nothing was wrong and that the floor mats had possibly been the cause of the acceleration.
