The first incident happened when I was slowing down for a stop sign. At about 45 MPH the car suddenly downshifted. The rpms registered approx. 5000 then returned to around 2000. I turned and while accelerating to highway speed, the car downshifted then corrected 3 times. I parked on the shoulder, shut the car off, then on again. I proceeded with no further issues. The next day, feb 26, 2015, the car downshifted at approx. 45 MPH then corrected. Each time the rpms jumped to approx. 5000 before settling back to approx. 2000. This happened a couple more times. Later the same day, I was on the freeway driving on cruise control at approx. 65 MPH when the car downshifted then corrected. This happened again a couple minutes later. I parked on the shoulder, shut the car off, then turned it back on. I did not have another incident driving to my destination. Feb 27th, I headed to my final destination. About 150 miles into my trip, I was slowing down on the freeway for a slower car in front, when my car downshifted then corrected. This same situation happened three more times before getting to my home. At no time did any diagnostic lights illuminate. I have not contacted the dealer yet, as they are closed today. After reading multiple reports about this incident I do not have confidence that honda will work to resolve this potentially dangerous issue.

Drive window and cruise control stopped working. Hondas are supposed to be the best cars, in my opinion I think they are the worst. I wouldn't never own another one. Everything brakes in hondas.
On backing into a spot in a private parking lot I struck a short steel post. I then moved forward, the backed again to park, however, the car shot back and kept ramming the post. I shifted into d with foot on the brake thinking I had a problem only in r, but the car shot forward and, in 5 seconds, entered the roadway, rammed a taxi, crossed the road, entered a sidewalk area, took out 2 lampposts and was finally stopped by hitting a car parked at the curb. In the entire episode, my foot never left the brake as skid marks attested. Unfortunately, I did not have the presence of mind to turn the key off. The impression given was the car was attempting to reach a cruise control speed which was normally set for approximately 110kph (68mph).
I bought my accord ex when it was 2 years old. The light on the radio didn't light up, so the dealership fixed it before I bought it. They told me it cost them $300. Also, my cruise control has gone out. And it's not the fuse.
Cruise control will not fully disengage. It causes sudden acceleration. *ak tapping the brake when the cruise control was engaged caused one to two second disengagement followed by sudden acceleration. The vehicle attempted to resume to the previous or another speed. This occurred with no operation. *scc
Cruise control disengaged while being on.manufacturer was not contacted at the time of the call.
My 2003 honda accord experienced an unintended acceleration while in motion. I increased speed from 40 MPH to 50mph to pass a slower moving vehicle in my lane and experienced a surge of power that I could not control by taking my foot off the gas. I needed to brake to restrain the vehicle. The tachometer went to 6000 RPM and stayed steady the entire time putting the vehicle in neutral as I prepared to kill the ignition returned control and the vehicle resumed responding. I have returned the vehicle to the dealer for inspection and am getting a response from the dealer that they have found nothing wrong with the car. I am a 47 y/o male with 30 years driving experience and am quite sure of the circumstances. Cruise control was not engaged as I was in morning rush hour traffic I have opened a problem ticket with honda n0112-17-00080. Thank you
