Unintended acceleration problem. Two episodes, months apart, both at very low speed. Was stopped behind two cars. Two cars in front started up to go through intersection. I took my foot off the brake and moved it to the gas pedal. Car started up normally. Then a child pushed to crosswalk signal which started to flash. I moved my foot to the brake pedal, and the car started slowing down normally, but then the car suddenly lurched forward. Both I and the passenger thought we had been rear-ended (but there was no car behind). It was a similar feeling to when the cruise control kicks in to accelerate, but no cruise control had been activated. I took my foot off the brake and slammed it back on the brake, and the car stopped. The previous episode had a similar series of events.

The outside temperature was below 32 and it was close to 25 or so. When I was driving the car at 40 MPH with engine temp still slightly above cold(not at optimal which is almost half way) and slowed down by using gentle brakes(not hard brakes). Just before the vehicle comes to a full stop, there is unintended acceleration and I could see even the RPM(scale) to spike temporarily. This has been happening every time when outside temp is cold and vehicle is driven with cold or slightly above cold engine temperature. There is a risk of hitting another vehicle or meeting accident if misjudge my braking because of this problem.. Please note : this problem disappears when engine temperate is at optimal and I have driving a honda accord 2008 exl for last 7 years(was bought new one), I never had experienced this problem in that car even when driven with cold engine.

I attempted to merge onto the expressway and after pushing the gas pedal the van suddenly accelerated beyond my control. I eased off the pedal and the van continued to serge ahead with no way for me to stop or slow it down as the brakes would not work. I saw the RPM reach level 6 and speed increase to 70 in seconds but as it was the expressway, I was able to keep my distance from cars in front of me. I switched the lever to the neutral position and the van slowed down and then I went back to drive and it roared back up to 70 MPH with the RPM again at 6 and I tried turning the cruise control on and then braking to see if it would shut down the gas but no luck. I went back and forth from d to n for about 2 minutes and then on one of the movements from n to d it shut down back to normal. I dropped the van off at my toyota dealer the next day and am waiting to see what "headquarters " decides.

I was driving in the middle lane on a three lane road. I arrived at a traffic light and came to a complete stop. I was standing in a traffic light with my foot on the brake. Standing in the same traffic light, there were many cars in front of my vehicle and several cars behind my vehicle. Suddenly, I felt my vehicle was attempting to move and smelled burning rubber from the right front tire. At the same time my foot was still applied firmly to the brakes and my vehicle jumped with a great force colliding with the vehicle in front me, which caused another impact and a third impact. The point of impact on my vehicle was the right side of the front of the vehicle. The left front tire was only two weeks oldand the other three tires were approximately 12,000 miles. The two front air bags deployed and the vehicle was totaled. My daughter was in the front passenger seat and suffered a tiny fracture in the rip cage as a result of the airbag impact. This was the first time we had experienced a case of sudden acceleration.
