"I am requesting that dot the federal safety agency investigate the driver's contribution to unintended acceleration (ua) and toyota's accelerator/brake pedal designs that make it possible. I was driving my toyota 4 runner in the neighborhood street of my community. My speed was less than 30mph and it accelerated suddenly. I applied the brake and instead of slowing down the vehicle began to gain speed. I pressed harder on the brake and it accelerated. The harder I tried to stop the car, the faster it went. I took my foot off the brake for a moment and the vehicle stopped accelerating. My foot was on the brake. It accelerated and would not stop so I pulled the car from the street to the curb covered by grass. It slowed down to some extent and then I intentionally to a turn and hit the median curb & tree to stop the car. I have continued to investigate unintended acceleration and have collected partial information.... Please formally investigate."

While traveling under cruise control at 55- 60 MPH on a rural 2 lane highway in nc, I came upon a vehicle in my lane traveling at a slower rate of speed. As I approached the vehicle, I accelerated to pass. While passing I could tell that the vehicle felt like it was moving faster than the 60 - 65 MPH it should have been for the amount of gas I gave it, but I was concentrating on completing the pass and did not look at the speedometer. After passing and pulling back into my lane, I depressed the brake to slow down. My vehicle slowed slightly but felt odd, like it was pulling. When I removed my foot from the brake, my vehicle began rapidly accelerating on its own, quickly getting to about 70 - 75 MPH before I depressed the brake again. Again the vehicle slowed slightly but felt odd, like it was pulling. When I removed my foot from the brake, my vehicle again rapidly accelerated on its own, at which point I realized something was wrong and depressed the brake harder. The vehicle pulled harder this time and started vibrating severely. I removed my foot from the brake and the vehicle again began accelerating. I shifted to neutral and brought the car to a stop on the side of the road. Over the next ~ 20 minutes I tried ~ 4 - 5 times to crank the car. Each time the engine immediately revved such that the tachometer almost instantly hit red zone, and I cut the engine off. I called toyota's "800" phone number, and they told me to get the car to a totota dealer. Before calling a tow truck, I tried cranking the car one more time, and that time the engine cranked normally.

When the air conditioner is running the vehicle idles at different RPM's causing it to lunge forward when the A/C compressor shuts down, increasing the RPM's. This has almost caused a fender bender several times while at a stop light.

This was the fourth occurrence of unintended acceleration. Each incident occurred upon shifting from park into either reverse or drive. The engine revved up to the red line upon shifting from a stopped position. This occurred with both a cold engine and a warmed up engine. I slammed on the brake and shifted into neutral. The accelerator pedal did not depress. Pressing the accelerator pedal in neutral brought the idle back to a normal levels.

I experienced a sudden acceleration on 10-5-10 in my 2007 toyota 4runner, 4wd. As I was turning onto a busy street at an intersection with lights, I pushed on the brake at the stop sign as the oncoming traffic approached, but the car continued accelerating into the lane at the intersection, and I pushed as hard as possible on the brake. I pushed the gear lever forward as the oncoming car veered into the next lane to avoid me. Continuing to push on the brake, I shifted into reverse, but the acceleration was still active and my tires squealed in reverse, so I shifted down into neutral and stopped, and the traffic had stopped also. Since the acceleration stopped I was able to drive normally, and there was no collision, thankfully. Toyota inspected the vehicle as usual, finding nothing, and said they adjusted the mat and that was that. I emailed the general manager about my situation and he said he would look at it again. I said I am aware of the intermittent problem with the electrical accelerator and would like to have him buy my 2007 and sell a 2011 4runner with the "smart pedal" technology. He agreed and now I own a new 2011 4runner.

I have a 2007 4runner, limited, v8 with the clunk in the driveshaft that appeared about 5k miles and hasn't let up now at 16k miles. I pull up to a stop sign and it feels like I've been rear ended. Then, when I start out, it feels like the brake release is delayed with another clunk. This happens at every stop. If the brake is not pressed firmly when coming to a stop, the vehicle will lunge forward. I first reported this problem to toyota at about 8,000 miles and they said that it was a lubrication and maintenance issue, stating that the propeller shaft was supposed to be lubed at every oil change. When I asked them to show me the maintenance plan in the manual, they admitted that this task was not listed in the maintenance plan for this frequency.
