While approaching a stop light on a city street and applying the brakes, the engine started to race and accelerate. I had to step very hard on the brakes to keep from entering the intersection. I got the vehicle stopped, but the engine continued to race; when I shifted into neutral, the rpms increased even more. I then shifted into park, and the rpms finally went down. Had I not stepped very hard on the brakes at the start of the incident, I would have entered the intersection and hit other cars in the intersection. When my son was learning to drive two years ago, he had two similar incidents when I was in the car. In both cases, as he was coming to a stop in a parking space the vehicle accelerated and hopped the curb. At first I thought he May have hit the accelerator instead of the brake, but now I wonder if he had the same thing happen to him.

I was traveling at about 60 MPH in the far left lane on 490 w in rochester ny on Saturday May 12, 2007 when I felt the accelerator pulled away from my foot. The car proceed to accelerate on its own. I looked at the dash to see if the cruise-control had somehow come on but it had not. I then tapped the brake to see if the acceleration would back off. It did not and I was now moving at about 80 MPH with the engine revving over 5000 rpms . I proceed to apply the brake very hard with one feet and then both feet to prevent from driving into the back of the cars in front of me. I was literally standing on the brake with both feet to try to negate some of the speed. The car was going over 90 MPH when I was able to pull over to the right side of the rode and drive off the road. …
While driving during rush hour traffic the vehicle suddenly without warning began to apply the brakes and the engine idled down then temporarily seemed normal only to have it reoccur in a matter of seconds. The vsa light including the symbol and the initials vsa became illuminated. I turned the car off and restarted it multiple times only to have it reoccur over and over again. I had just had the catalytic converter replaced for a second time two weeks prior to this happening. I was told by the dealer that in replacing the catalytic converter the service crew punctured my radiator and had to replace that as well. I had the car towed to the dealer who told me the vsa senor control cluster needed to be replaced. They said that they had never seen this before. They indicated that the part would take a week and a half to get the part which seems very strange. …
I was driving my 2005 Honda Odyssey today and as I was pulling into a parking space (about 5 MPH) at a drug store and coming to a stop, the vehicle suddenly accelerated (jumped) forward. Had I not already had my foot on the brake I would have hit a rack of propane tanks! The car traveled about 4 ft from acceleration start to stopping and it rolled over the curb. My hard braking left a foot of tire tread marks on the concrete sidewalk from the front wheels. I always keep the cruise control (cc) off when driving locally but after I stopped the car, I noticed the cc was on. I did not turn it on and do not know how it activated. I want a record of the event. It left me shaken and want to insure that if there are other reports to nthsa actions be taken to advise owners of the problem. Drove to other locations without further problems. …
