Filed May 5, 2022 · Acceleration · VA · crash

On December 29, 2021, while backing up my 2012 Toyota Highlander accelerated at speed that I was unable to control. One car that was packed in the driveway was damaged beyond repair. An office building where I was working was damaged and has been accessed with a loss of over $100,000. I contacted Toyota after knowing that there was a recall regarding unintended acceleration in some Toyota cars. Toyota sent an inspection team to Geico Insurance company which had taken over possession of the car. The inspection team and the Toyota representative assured me a final report would be sent to me within a month after the inspection had been completed but even up to this moment Toyota has not responded to my email requesting for the report. You can reach out to Toyota and reference File # 220105001224. For the six years I owned the car, i have never been informed of any recall. My car was regularly serviced by Toyota Ourisman Chantilly and Ourisman Toyota Fairfax.

I was stopped at an intersection (red light) and was needing to make a left turn. The light turned green but this intersection does not have a green arrow so you have to yield to the oncoming traffic. As I proceeded forwarded a little bit into the middle of the intersection so I could make my left turn, I slowed down to almost a stop because there were too many cars and I couldn't turn at that moment. Then there was a window of opportunity for me to turn shortly after I slowed down almost to a stop and I stepped on the gas to go, then nothing happened. The vehicle just paused for about 2 or 3 seconds and then suddenly jumped forward. My wife was in the car and she thought it was me mashing on the accelerator pedal but I didn't, it's just that the vehicle didn't do anything and then suddenly jumped forward! Luckily when this delay happened, I wasn't in the oncoming traffics lane, nor were there any oncoming traffic close at that moment. At the time this happened, I even thought maybe it was me not giving the vehicle enough gas, but it happened again about a month later. This is when I did a google search for delayed acceleration and I came upon other's who have mentioned the exact same thing happening with their toyota vehicles as well. Please look into this as this is very dangerous. This vehicle is less than two years old and I've read that others have had this problem with their older toyota vehicles. I've even read that toyota knows of the issue already but they have no fix?????

While pulling into a parking stall in a private parking lot, my highlander suddenly accelerated and I had no brakes at all! My highlander went up over the curb which caused the vehicle to slow. I had brakes again and was able to apply the brake, coming to a safe stop. Not before slashing my left front tire and bending my tire rim. Thankfully no one was injured.
