Sudden unintended acceleration : while my wife was driving the vehicle on the driving lane on I-5 south at about 60mph and I was at passenger's seat, my wife yelled "the car is getting faster and faster." and I told her to step on the brake. She said she was already peddling the brake but it did not work, and the car was approaching to a big truck in front of us with frightening speed. Since there were many cars in front, behind and on the passing lane at the time of the incident, we could not do anything else but steering the car to the right side off the driving lane in order to avoid fatal accident. There was space covered with rough grasses, bushes and soft fences there. The vehicle kept moving along, crashing the objects with high speed of about more than 85 MPH. Finally the car stopped after going along more than 50 yards. …
I was trying to back into a parking space with my 8 month old, 2012 Honda Civic. As I took my foot off the gas pedal to put the car into reverse and before I could step on the brake, the car surged forward at a tremendous rate of speed, jumped a curb and went straight into a brick building. The car bounced backwards onto the parking lot and I was able to step on the brake and regain control. This happened in a matter of a split second with no time to jam the brake on as the car lurched forward. Even though the car jolted tremendously, the air bag did not go off, but a service light came on the dash board indicating "check airbag system."

I have a 2012 Honda Civic lx, it has intermittent problems with unintended acceleration. It occurred twice on the highway and also urban area. Just this morning, it happened again I was on the highway when I noticed the car suddenly accelerates and speeds up without stepping the gas pedal. Fortunately the brakes responded to slow down. I came out of the highway, and I had to stop at a red light but still it was a constant fight acceleration by itself and stepping on the brake until the car will operate normally.
Driving up to a drive-in bank the car suddenly accelerated. I stopped the car a few feet beyond the teller window by a heavy application of the brakes. I put the car in reverse and backed up to the window. In reverse the engine was still racing. I put the car in neutral and the engine continued to race. Upon finishing my banking transaction I put the car in drive. The engine slowed to a normal idle I took the car to the dealer for service four days later; the dealer found nothing abnormal.

At approximately 7:45 a.m. I arrived at work and turned left into parking space to park. I was driving a 2012 Honda Civic, which was less than one month old. The car lunged forward when I took my foot off of the accelerator, jumped the parking bumper and struck a concrete wall. The driver's air bag deployed and the front bumper was scraped and knocked out of place. American Honda has inspected the car and claims that nothing is wrong with it but refuses to release its report to me.
