I bought a new Honda Accord about 7 months ago. I noticed after driving it a month or more that every long once in a while it was showing me a defect known as "unintended acceleration". I took it in to the dealer and after they examined it, put it on the computer machine and test drove it a few miles, they found it to be perfect, nothing wrong with it. I took it back and continued driving it thinking that perhaps I did something that caused it.as I continued on with it, I pulled into my handicap space at my parking lot. Front end up to a concrete bunker with the handicap sign standing tall in front. I was about to put the car in park and shut the key off, when suddenly while my feet were off the pedals the car zoomed up to 40 mph, I turned the wheel left to try and avoid the sign after it hit the bunker and as it sped into the next parking lane I braked and shifted to neutral.luckily there was no traffic in the second lane or I would have killed somebody as well as myself.I took it to two more dealers with a damaged passenger fender and they all said after looking and testing again that there is nothing wrong with the car. The last dealer brought a Honda expert mechanic in from the manufacturer and he too said nothing's wrong. Without evidence they can do nothing for me.if we can't find the trouble you say is there, we can't accomodate you. I said, so your sending me home now to get killed?sorry but there's no proof. I called Honda manufacturer and they would do nothing.

While overtaking a large truck (semi), in the fast lane of a four lane divided highway, the adaptive cruise control flashed a warning and automatically applied heavy braking as my vehicle was even with the rear of the semi trailer. This caused the vehicle behind me to nearly rear-end my car. This has happened several times over the past year, and seems to be more frequent lately. I am nervous about using the acc when approaching or passing a large semi tractor trailer. I have seen other comments regarding the same situation posted on the internet. I believe this is a serious safety issue, and should be investigated.

While driving in stop and go traffic, either on the highway or on residential streets, occasionally, the vehicle will hesitate. This hesitation will last 1-3 seconds and then the vehicle will accelerate as expected. This hesitation can cause a dangerous situation since the vehicle will not move as expected. The vehicle was purchased new, and this has occurred since its purchase. I've taken it to the Honda dealer, but they can not duplicate it since it is an intermittent issue. Their response was to stop using the econ button. I have stopped using this feature, but the issue has persisted, (although it has lessened in occurrences). The issue can occur 1-2 times per week, with the last occurrence on 12/8/15. There is a technical service bulletin on the vehicle 15-036, which may or may not be related, but last time at the dealer, they couldn't find the tsb, so the software update likely has not been made to the vehicle.

Intermittently, but always upon acceleration (could be pulling onto the highway from a stopped position, merging/speeding up to get on the highway or pass another vehicle, or starting to move when the light turns green) the car will fall flat with no power. It doesn't stall, just doesn't respond to the gas pedal. Most times, happens in second gear. Releasing the gas pedal and then pressing it again most times resolves the problem. Sometimes, it takes a few tries. This is a very dangerous problem, and I have had many motorists swerve around me or blow the horn at me because I can't get the car moving fast enough. I just spent $30,000 on this new car, and the dealership cannot duplicate the problem so they're sending me on my way with a vehicle that's a potential death trap.
