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.

4Runner 4WD 6-cyl

I have owned this vehicle for over 7 years. Today, the only occasion of the following occurred. Driving I-95 in North Florida at approx. 72 mph, I removed my foot from the accelerator to begin a lane change as I approached a slower vehicle to the front. The accelerator, of its own Accord, pressed itself to the floor and the vehicle began to accelerate on its own, reaching a speed of 93 mph within a few seconds. I applied the brakes, which were totally ineffective; the vehicle continued to increase in speed. I came within a few feet of rear-ending the car I had begun to go around, and just before impact I turned off the ignition, which cut off the motor. I moved from the middle lane to the shoulder of the road, and while coasting, turned the key back to the 'on' position, without starting the motor. Instantly the motor revved on its own to tach redline, and I turned the key to the 'acc' position; the motor shut off. This occurred three times, and the entire time the accelerator pedal was pressed to the floor. It was not stuck under the floor mat, as I checked this while coasting. The pedal could not be pried up by my toe, but was stuck fast. I had reduced speed to about 30 mph. After 1/2 mi coasting, the pedal returned to the normal position on its own, and I was able to start the car. It drove normally the entire way home, about 60 miles. If I had panicked and not turned off the engine within the few seconds I had, I would have certainly impacted the car in front of me which would have resulted in a crash in excess of 90mph. There was traffic around me at that point, and it would have resulted in a multiple-car crash. This is my wife's car and I cannot let her drive the car again. I find no recalls, but this situation most certainly was very real, and very dangerous. This is not to be dismissed by calling it 'driver error', or a pedal stuck under a mat. I stayed rational, and controlled the situation. Do something meaningful before someone else dies, NHTSA.

I have a 1998 Toyota 4-runner. It, too, has random acceleration problems. Over the years I have had it checked by a mechanic for problem identification no less than 10 times but no problems were identified and therefore nothing was fixed.. the occurrences are sporadic and unpredictable. I do a lot of freeway driving and thus, most have occurred on freeways and without any significant consequence, the car was bought used.
