Notes: The 2005 Honda Accord suffers from transmission failure. It's not a huge widesperad problem like in prior years, but definitely still something to consider.

The transmission begins slipping & eventually has to be replaced, typically soon after 90,000 miles & with a repair cost of over $2,000.

Transmission failure problems have been a huge problem for the Accord & several other Honda models all through the early 2000s model years. Honda eventually extended the transmission warranty to 93 months/109k miles for the 2000-2001 Accords as a class action lawsuit settlement, but owners of other Accord model years with transmission problems are out of luck.

I was driving on the highway and I when I removed my foot from the accelerator pedal the car kept up the same speed. I put my foot on the brake and it did not slow the car. I downshifted all the way down to first gear yet was unable to slow the car. I finally turned off the engine and was able to stop the car on the side of the highway. I had to go through a red light and fortunately there was no cross traffic. No accident occurred in this incident but there were four of us in the car. I had the car towed to my mechanic and he determined that the cause was the throttle body assembly failure. It is now repaired.

The contact owns a 2005 Honda Accord. While driving at any speed, the driver stopped at an intersection and the vehicle idled at a high speed. The driver had to apply extra pressure to the brake pedal to prevent the vehicle from accelerating. During the failure, the contact had to shift into neutral and turn off the vehicle. The vehicle was taken to an independent mechanic and the throttle body was replaced twice; however, the failure recurred. The manufacturer was notified of the failures. The failure mileage was approximately 167,000.

I was leaving a store on hull St. And my car was at about 40 mph and all of a sudden stopped moving and I felt that it was something bad so I cut the car off and restarted my car and it started up nicely once I switched gears from park to reverse the car didn't move. So I went to put car into park and there was a really loud noise which scared me crazy. I cut the car back off and it began to roll backwards in the park gear so I had to put the car emergency break on to keep in place. Monday morning which I'd today I get my car towed to aamco and they diagnostic my car as a shaft failure which had broken which caused the car to make the loud noise when placed in the park gear and the car doesn't realize which gear it's in because it is broken inside the transmission

This is the second time that this vehicle causes an accident due to involuntary acceleration defect. I was coming to a complete stop to park the car when all of a sudden it accelerated on its own and sped into a building. First it hit an iron bench pushing it into the wall. The car missed hitting a young mother and her four little kids by mere seconds. My insurance company sent one of their own adjusters to inspect the damages, and determined that the car should be repaired. In the meantime the people at the body shop where the car was towed to kept telling me that the car was not safe to be put on the road again. I pleaded with my insurer to have it totaled as I was too afraid to drive it again after two accidents, and my conscience did not allow me to sell the car after the repairs putting somebody else in same kind of danger. I also called Honda, but their reply was that Honda was not going to do anything about it. Honda folks were even annoyed that I called them saying that my insurer was the one to contact them through the proper channels. Finally my insurance agreed to total the car. However, I saw that the car was sold to an auction dealer listing it as "salvage title/rebuildable." The car is for sale again stating that it will cost $4,872 to fix it. My insurance company increased my premiums considerably considering me the party at fault. I ask NHTSA to act quickly to stop this unsafe and unfair practice.....updated 08/20/15 updated 9/30/2015

Car details: - 05 Accord SE coupe with ~65K miles (automatic transmission, 4 cylinder) recently, I have noticed that the car will not accelerate even when I keep pushing the gas pedal. Typically happens at around 50 to 60 mph marker (the mph needle will just stall at one location and not move). I have to tap the brake lightly a couple of times or let the car coast down without giving it any gas (it kind of releases whatever is holding the car from accelerating and releases the mph needle). I then accelerate the car again and it will go higher than 60 mph. Keeps happening often (not every time though). My gas mileage is lower which confirms that something is happening. This is a serious safety issue on highways. I am not sure if this is related to all the transmission failure issues that Honda Accord continue to see on models manufactured in the mid 2000S.

I was driving on interstate 20/59 near ft. Payne, Alabama with the cruise control set on 75 mph. I changed lanes to pass a slower car but did not touch the gas pedal. The car started to accelerate on its own. I tapped the breaks to turn cruise control off but the car continued to accelerate without touching the gas pedal. The acceleration was not a full throttle acceleration, just a moderate increase. I then shifted the car from drive to neutral and the RPM's jumped up to redline, again without touching the gas pedal. Luckily, a rest area was approaching and I managed to pull the car into the rest area parking lot playing with the drive/neutral of the transmission and using the brakes. Once I made it to a parking space I turned the car off and shifted it into park. I waited a few seconds and turned the car back on. The RPM's again jumped up to redline without me touching the gas pedal. I shut the car off again and put my foot underneath the gas pedal and pulled up. I cranked the car again and it acted normal. I checked under the hood and everything looked fine. After some deliberation, we decided to continue on our trip and the car was fine for the next 4.5 hours. We drove back Sunday, May 19 and the car again drove fine for 6.5 hours and hasn't had a problem since. The morning before the incident, I changed the alternator and oil. I strongly believe that this had nothing to do with the alternator or oil change. Also, I doubled checked the carpet mat in the car and it was not even close to the gas pedal. I am not sure if anyone else has experienced this problem with a Honda Accord. I am a mechanical engineer and I am dumbfounded by this. Being in a car with uncontrollable acceleration is quite unnerving.

My brother was driving our car on the 278-bqe in brooklyn, NY. The RPM on the car suddenly went to 7000 RPM and then the car started to decelerate. The car would not accelerate and it ended stopping on the express lane on the highway. He had the hazard lights on but cars were still coming at 60-70 mph, many barely missing the car as they swerved into the next lane. We took the car to the mechanic and though the car only has 78K miles on it, he said that the transmission is dead. Everything else was in order in terms of fluids. I took a look at and there are 43 complaints on this exact issues of 2005 Honda Accord owners with 60-80K miles on their car.
