I experienced a sudden unintended acceleration (sua) in the parking lot of my apartment on March 3rd, 2012. It was a sunny day, and the road condition was good. My wife was driving Lexus rx 350 2011 model (mileage: 2124miles). My daughter and I were sitting on the back seats. She was slowing down the vehicle for parking and about to finalize the parking by going forward by about 3 feet. At that time, the vehicle abruptly accelerated with the sound of revving up the engine. The car ran over a parking block and went on curb stones. By help of the brake override system equipped after the recent Toyota's recalls, she could stop the vehicle quickly because her foot was already on the brake pedal. We all were surprised at this rare situation, but fortunately there were no accidents or injuries. We reported this experience to a close Lexus dealership. Two Lexus engineers inspected the vehicle, including 10-mile test driving. However, they could not find any mechanical problems. They could not re-enact the same situation, neither. At this inspection, they did not check out the event data recorder, as well as any electronic systems like etcs. According to the inspection result, Lexus directed me to keep driving this vehicle with my own risk. This is not related to the floor mat interference problem that led to the massive recall in 2009. So, I think the current Lexus users, as well as potential consumers, should be aware of the possibility that they can experience the similar unintended acceleration while driving or parking.
