Unintended acceleration with car going out of control on the highway and the car failing to slow down after pressing on the brake. Most terrifying experience of my life.

- Hummelstown, PA, USA

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 carcomplaints.com and there are 43 complaints on this exact issues of 2005 Honda Accord owners with 60-80K miles on their car.

I have an 05 Honda Accord coupe. Neither window will roll down, had the relay switch replaced but 6 months later back to the same problem. Radio would go on and off, even when car was off. Now the radio will not come on at all unless I unplug/plug the battery, then the result is only temporary. Now the cruise control button will not work. If I push it down the green indicator light comes on but the button will not stay engaged. I've seen so many of the same complaints I was sure there was a recall I missed but there isn't??!!

On Saturday at 11:50 pm, I was cruising at the 169th & maple rd, omaha, ne parking lot.. at a front parking junction, I made a right turn at about 2-3 mph speed. I slowed and braked for a pedestrian walking across my path. My car started revving and accelerating rapidly. I immediately pressed the brake pedals harder. The harder I pressed, the harder the acceleration became. I became very concerned and scared that the car might accelerate suddenly and may cause a terrible accident. I quickly move the gear hand pedal shifters foward to (P)ark. The car jerked forward a bit and then stood still; however, the engine started revving with a loud din and then back to normal.I started to slowly move the gear back into (D)rive mode. The car behaved normally and I parked my car in a available parking slot. Prior to this incident, I had a minor incident similar to this. This was a about 2 weeks back. I was slowed and stopped at a traffic light to make a right turn to maple. While in stop mode pressing the brake, the car started jerking and accelerating forward slowly. I quickly pressed the brake harder and it jerked forward and stopped. At that point, I just shrugged it off, thinking that was unusual but wasn't really bad to take issue. All this happened when I changed my Accord hybrid battery and a hybrid controller over a month back when I had a hybrid battery and the controller that needed to be replace on account of a safety issue with the car. The car felt ok after the change. However, I had the car since 2005 and never did I encounter a sudden acceleration on this car, not once until after the battery and controller change. I can only relate now to what actually has happened and is very concerned for my life and my family to whoever drives the vehicle.

I previously drove my aunt's 2005 Honda Accord hybrid on several occasions. Almost as soon as the vehicle was purchased, on more than one occasion, the brakes failed and caused accidents. The accelerator would also accelerate on its own. The car would simply speed up on its own. The car would also at times stop or turn off on its own. I assumed because the car was a hybrid or different that it was normal. At times when accidents would occur, I couldn't believe what had happened. The car literally drove away. A few times others drove the car and mentioned the same. My aunt previously tried trading in the vehicle, but it was too expensive to trade in. On January 11,2011. A fatal accident occurred while driving this vehicle. My mother, whom is a precautious driver was driving my cousin to school and were involved in a fatal car accident. The Honda struck a school bus right in the middle. I believe the car like on many other occasions accelerated on its own or the brakes failed. I feel devastated that I have lost my mother and cousin because of this accident, but feel that my mother was not at fault. She was always a safe driver and in this case I believe the vehicle was at fault.

Sudden acceleration of car. Pulling into a car bay, almost stationery. Accelerator appeared to be sucked away from under foot. Brakes applied, but car accelerated very fast over the curb and into wooden bollards (hitting so hard it ripped them out of ground, and broke in two), the car felt like cruise control had kicked in. I did not "accidentally" hit the accelerator, and my floor mats are no where near the accelerator (they are hooked down).

Service engine soon light comes on and it indicates that the throttle position sensor is defective I brought the car a month ago and it only has 64K on it. My experiences with this code are bucking and jerking of the car idling surges sudden stalling hesitation while driving and a sudden surge in speed while driving on the parkway also my fuel drops drastically. I called Honda and I was told by a service repairman that I need to change the tps sensor but I would have to buy the whole throttle body totaling 500 since the tps sensor($45) is not sold separately. Also this is causing my shifter to get stuck I cannot shift my car into drive.
