“I have a 2004 Honda Accord that had a transmission failure with no warning. It had 88,000miles on it and very well maintained. I was driving on the highway about 2 hours away from home when the car started slowing down or downshifting on its own. I felt like I was just coasting or in neutral. I pulled over to the side of the road and waited a couple minutes and tried to start my car up again...it did. I started driving again and not even 3/4 of a mile later the same thing happened. …”

“I did the routine maintenance on my Honda Accord. I have followed all of the specifications regarding oil changes, maintenance on the transmission, timing belt replacement, etc. Unfortunately, even with the routine maintenance performed on this car, my transmission failed on a road trip on july 7, 2012. I was driving on the interstate going 75 miles per hour when my Honda Accord would not accelerate anymore. Thankfully, I was able to safely pull across three lanes of traffic in order to get to the shoulder. …”

“When parking the car in a parking lot, as I was turning into the parking space the car jumped (went very fast forward and hit the wall in front of me) even though I had my foot on the brakes I felt I had no control of the car and the engine turned off on it's own. I also noticed it jumped gears, it was no longer on d but d3. This incident caused damage to the bumper of the car.”

“On january 2, 2004 we purchased a Honda Accord ex. The car is red in color. Total cost was $25,998.50. We have enjoyed this car since we purchased it and about 6 months ago we made the decision to replace the timing belt. That was on april 8, 2011 as the mileage neared 100,000. Since that time (probably in may 2011) we started to notice some peeling on the front above the windshield and also some around the rear window. It has gotten worse with each passing day. Had we known this was going to happen we would not have replaced the timing belt. …”
