As I was accelerating on a city street, going uphill, the accelerator got stuck in the pedal-down position and the car started revving on its own. At the time, I was going about 10-15 MPH and the car accelerated to about 25mph before I was able to stop it. I quickly removed my foot from the accelerator and stepped on the brakes which slowed down the acceleration, but did not stop the revving or the acceleration. I tapped the accelerator with my foot which seemed to loosen the accelerator (it became unstuck) and stopped the revving of the engine. I pulled over to calm myself before driving on. This was the third time I have experienced this; the other two times happened on the freeway and was resolved the same way; by stepping down on the accelerator to make it unstuck. The action is very similar to the emergency-brake engage/disengage function on the toyota sienna.

On mon 10/22/2012 at 11:15 am I experienced sudden uncontrolled acceleration driving my van. I was traveling on I-696e in detroit at a constant 70mph, then slowed to 45mph due to construction. As traffic cleared the construction, I pushed the accelerator pedal to pass a semi-truck. I felt the accelerator continue to depress, I completely pulled my foot off but the pedal did not come back nor did the vehicle slow down. Rather, it did just the opposite and continued to accelerate. I attempted to brake hard with no response--the vehicle did not slow down. Then I put the van in neutral to slow down the engine with no results, the van continued increasing 60+MPH with no foot on accelerator. This is when I became extremely frightened. The vehicle was pulling from side to side. I looked down to see if there was any interference from the floor mat and none was seen. I tapped gas pedal - no response. Next I put van back in drive and braked --no response again. Then I downshifted to 4th, the engine did not slow, and further downshifted to 3rd gear. Finally, the engine responded and slowed. I used the gas pedal cautiously as I then shifted to 4th so that I could exit the freeway. I parked at my office & immediately called my husband first and explained what happened and I then immediately called the our toyota suburban dealer. They told me to bring it in for inspection. I was still shaking when I brought the vehicle in and extremely upset. After two inspections, they stated sudden acceleration was caused by the floor mat. Although this seems reasonable, it does not explain why brakes failed to overcome the engine, and shifting to neutral failed to disengage the transmission. The vehicle scares me to death. I do not know what to do next. I consider myself a serious witness as a registered nurse (rn/bsn) with 20 yr manual driving. Ref toyota case #[xxx] and #[xxx]. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

Engine/powertrain hesitates for 1-3 seconds when accelerating slowly, or accelerating quickly after slowing down such as when slowing down in an intersection, making a turn, or in slow traffic. Engine has piston slap for 3-5 minutes after a cold start in weather below 40 f. The slap becomes louder with colder temps. Shifting into gear with a cold engine can cause the vehicle to lurch due to high idle. Driver must have foot firmly on brake before shifting into gear. Problem diminishes if engine is allowed to warm for 45-60 seconds. When parking, the driver must keep the brake fully depressed, shift into park, pause 1-2 seconds before releasing brake. It seems there is a brief delay between gear lever being placed into park, and powertrain actually going into neural/park position. Releasing the brake too soon will allow vehicle to roll ahead 3-6 inches.
