Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

I was driving along and all of a sudden my car begin to accelerate on it's on. The engine was revving and when I went to apply the brakes the car didn't at first slow down. When I finally reached home and put the car in park the engine was still revving as if I was stepping on the gas. It was very scary and intimidating. The same identical thing happened to my husband when I asked him to drive the car around the block.

My 2005 Mercury Sable suddenly had the cruise control stop working approximately 30 days ago. The next day some serious issues began to happen. I was traveling down a curvy 4 lane road at the posted speed limit of 45mph. Knowing there was an up coming light I took my foot off the brake and anticipated the normal deceleration. Suddenly rather than slowing down my engine independently revved up to 3/4 RPM causing me to instantly jump to 50/55 mph. Apart from the immediate panic I have never had a vehicle react in this manner and was at a loss for what to do. I hit the brakes extremely hard to combat the acceleration while putting the car into neutral (still going 40+ mph). Despite having the car in neutral it was still revving itself at around 3 RPM. After slowing down to a safe speed I turned into a parking lot and immediately turned the car off. I left the car resting for about minutes and when started again, it immediately began revving the same as before. I am very concerned and have been since troubleshooting with my mechanic. This is clearly a very dangerous issue and significantly lowers my mpg while putting triple the stress on my brakes.

While driving recently, my 2005 Sable suddenly accelerated, forcing me to brake and put the car in neutral while at speed. This has happened 3 or 4 other the past. Now the cruise control does not work anymore.

Accelerating from a stop light and letting off accelerator paddle, the pedal. Approaching the next light, braking hard helped. But putting the car in neutral was the best option, given the speed and how close the light was when I was not able to stop the peddle from sticking. At the light in neutral, I pumped the accelerator pedal several times until it did not stick any more. If breaking hard and putting the car in neutral, if going the posted speed or more traffic, there definitely would have been an accident. That day I saw on different website complaints about this and called the dealership. They inspected the car and lubricated the accelerator cable throttle body and the cable just incase. But they could not find a problem.

My car has accelerated without application of the throttle. I did not have cruise control on or engaged and the car continued to function as if the gas pedal was depressed. This has happened on several occasions now. Once, while at a speed of about 30 mph, I was able to safely pull over and put the car in neutral. The engine rpms continued to race upward as if the car was under load and under throttle input. There were no floor mats or any other obstacles or objects making contact with any controls or devices.

Driving the vehicle at about 30 mph. The car accelerated to about 60 mph at which time I was riding the brakes the entire time till I could pull over. The engine goes to 4000 RPM while in park. If restarted its the same thing. This was happening off and on. I took to garage and they cleaned and checked carburetor and fuel pump. It continued again and I finally took it in again. This time they changes the cruise control cable. Again, it continued again and I finally took it to the dealership which they replaced the gasket. And again I am still having problems with the vehicle. I would love to sell this car and get a new one, but I cant afford it. I was hoping to be able to give this car to my 16 year old daughter, but that is totally out of the question as I do not feel the car is safe to be driving. I also can not afford to be taking this vehicle in the shop and paying for parts that just don't seem to be working. Please look in to this matter as I believe their are many people out there in my same situation, but have not taken action as they just give up. The last thing we need is for people to get injured or die from this problem.

My car is accelerating on its own like the gas pedal is stuck or something. The RPM goes all the way up to 4,000. It is very scary because you don't have control of the car speeding on its own which is very hard to come to a complete stop.when I finally manage to stop the car by putting the car in neutral and hitting my breaks, I then put the car in park. The car still continues to accelerates on its own. I have to tap the gas pedal to make it calm down or it will keep accelerating even if I turn the vehicle off and start it back up again.

While driving the vehicle in neighborhood situations or other situations the vehicle accelerates on its own beyond the on the desired speed this causes the car to be difficult to control and very difficult to stop increases the stopping distance needed to avoid an accident to stop at a red light or stop sign it also causes the engine to race even when placed in neutral. Recently why stop at a stop sign the car was pushing it South forward so hard I had a hard time keeping it stop and it actually moved me beyond the stop sign into a oncoming traffic. Extremely dangerous situation there will B fatalities if this is not corrected. This spontaneous acceleration even allows me to drive up hills without having my foot placed on the gas car will not slow down or stop easily. This started in March and it's happening everyday causing wear and tear on the brakes it makes it difficult to steer and I am in fear while driving. I've now started to drive with the brakes on 100 percent of the time in order to keep the car at a controllable speed I've read other complaints on mine similar to this I believe it's a known issue and I'm hoping for a speedy recall by Ford to correct the cause. Since this is a known issue and and I think they linked it to either the accelerator cables or the cruise control.while driving in neighborhood traffic at 25 miles an hour the car can accelerate above 50 very dangerous!!!!!!

2005 Mercury Sable with only about 60,000 miles car accelerates by itself nearly causing an accident. The acceleration is so strong that it overpowers the brakes and happens while driving at any speed. The only way to stop the car is to shift to neutral and hope for the best. Ford dealership said it was a faulty speed control line which they want nearly $500 to replace.

The car started accelerating on its own to 80 miles per hour in a 35 mph zone. There was a high risk of striking pedestrians. Immediately put the car in neutral and slammed the brakes and also engaged the parking brake. It was a very scary experience. Took the car to the dealer and the dealer was able to replicate the problem in the parking lot. Got the car throttle body replaced for $376. Apparently the throttle body sticks. Did some research on the internet and found that NHTSA has been investigating this issue for a long time. Not sure why a recall has not been issued? this defect could result in people getting killed -- I feel that I have a responsibility to ensure that something is done so that others do not experience the same problem.

I was driving 25 miles an hour with my children down the road for the start of a long trip and the car accelerated on its own and I had to use my brakes to not hit anything or run a red light. This has been continuous since that day and I can tell it has done damage to my brakes. They will have to be fixed but if this continues I'm afraid there will be an accident.

Vehicle maintained and accelerated speeds while on level ground with no cruise control engaged and foot off of the pedal. Depressing the brake slowed the car down, however rpms were still pushing 3.5X1000 according to the instrument panel. Turning cruise control on/off seemed to fix it. Upon starting the engine, car idles extremely high upwards of 2.75-3.00X1000 RPM's. turned cruise control on and off then I heard a click...then power cycled the engine and normal RPM's since. However cruise control does not work anymore.

Car started accelerating on its own and had to put the car in neutral and put both brakes to make it stop. The car lurches forward when it is stopped at signals.did some research online and found that this has been an issue that nhs has been investigating and is related to the throttle not closing. why no recall yet?

I was driving down the road and my car began accelerating on its own. When I came to a stop, it would lurch forward and rev very high. From a complete stop, the car was able to accelerate up to 50+ on its own without ever touching the accelerator. To get it to stop, I either have to shut the car off or "punch" the accelerator.
