I was driving and without any warning the car shutdown down, the car controls would not respond. The car continued till it lost momentum stopped, there was no/or very little braking and steering assistance/control. ** called Toyota and reported the problem, no assistance was provided*** the dashboard flashed lights, the vsc, AWD and other lights came on. Fyi - the car has been regularly maintained. There are numerous controls on these similar issues, vsc AWD ECU etc, but there seems to be no acknowledgement from Toyota.

Highlander 4WD 6-cyl

  • 114,600 miles
2007 Toyota Highlander hybrid, V6, 4X4 --- on November 23rd, 2011, at approximately 10:00am, I was driving with my family on I-5 South in the central valley of California. The cruise control was on, but not engaged because the traffic was too heavy. My speed was approximately 65 miles-per-hour, going uphill. Unexpectedly, the engine began to race. I applied the brakes to keep the car at the speed of traffic and examined my cabin for clues of the problem. The transmission lever was still in "D". I turned off the cruise control, but that made no difference. I momentarily released the brake and used my right foot to ensure that the accelerator was not stuck. It was not. During that time the engine power meter jumped up to full power around 200 kw. I re-applied the brakes to decelerate and brought the car to a stop on the right shoulder of the highway. As soon as the car was completely stopped, I shifted to "P" and turned the key to the off position. Some smoke appeared for about two seconds, which I presumed was from the brakes. I then examined the floor mat, but it was not out of position. I waited about 30 seconds and turned the key back to the on position and the "ready" signal illuminated on the dash. The acceleration problem was gone. I drove about 15 miles to the next exit and stopped for gas. I checked the oil, coolant, and brake fluid levels, which were all good. The problem did not re-occur during the additional 250 miles that I drove during that day. There were no injuries. I called "crown Toyota", where I had purchased the vehicle new and spoke to a representative there. He told me that he did not know of any other acceleration problems other than those that were floor mat related.

On May 9, 2007 we purchased a new 2007 Toyota Highlander. About a month later it unexpectedly accelerated and ran through the end of our carport while being driven in to park. Luckily no one was in front of it. The auto sustained about $650 in damages and the carport received similar monetary damages. About a month later we had a similar incident while parking in a parking lot. At first we attributed the incidents to my wife's foot someway slipping off the brakes and on to the accelerator. Now, after the recent national publicity, we are not so sure. Perhaps the accelerator mechanisim or software in this vehicle is defective in this model Toyota also. In the mean time, I now wonder if this model vehicle is safe to drive. I will bring this issue up to our Toyota dealer in the near future. I hope this information will be useful in helping the government and Toyota to solve this important issue.

Parking my 2007 Toyota Highlander in my parking space at work. I go to park and my gas pedal is stuck and accelerated into two other vehicles resulting in $3000 to my vehicle and unknown amount to the other two vehicles. Nothing has been done so far to correct the problem. It has only occurred once so far.

I have a 2007 Toyota Highlander that had mat entrapment--I had after market mats as none were given to me when I bought the vehicle--I reported this to Toyota corporation and had vehicle inspected at dealership and rep said there was no defect in my accelerator--the vehicle had accelerated and I hit a picnic table and 2 bird feeder and a fence in my yard before I got the vehicle to stop. I would like to know what is different about my accelerator as the 2007 is not on recall but I feel it should be--they did not explain that to me just told me that my floor mat caused this to happen--I realize that but I would like an answer to my question--I blew a Michelin tire and have damage to my bumper--total cost--about $600 according to Toyota garage--no answer from them except to say this was my fault.

Highlander 6-cyl

  • 5,000 miles
2007 Toyota Highlander 6-cyl limited running under cruise control will slowly begin to accelerate when "resume" is pressed in order to get back up to the cruising speed. However as the speed nears (within 4-5 mph) the cruising speed, the transmission downshifts resulting in a hazardous quick acceleration that requires braking or quickly turning off the cruise control. This occurs regularly during high speed highway driving. The problem can only be avoided by manually returning the vehicle to cruising speed before pressing resume. The dealer states they have no knowledge of this problem.

Acceleration & de-acceleration problem: When the vehicle is in forward motion, on a highway, and I press on the accelerator to rapidly speed up, there is an approximately one second time delay in the vehicles response to my request to accelerate. Frequently, this delay has almost caused an accident. On the occasions that I want to speed up to pass a vehicle, or to change lanes or to avoid a potentially serious situation, this delay is very startling. Because of the vehicles response delay, I then sometimes suddenly take my foot of the accelerator to cancel my accelerate request. However, the vehicle, after its initial acceleration delay, will then accelerate for just a moment even though I have now just taken my foot off the accelerator. In my almost 50 years of driving many vehicles, accelerators always responded instantly. That's because there was a linkage cable that mechanically connected the gas pedal to the carburetor. Now, in this Toyota, it is computer controlled. When I complained about this delay to my local Toyota dealer, they tested the vehicle and advised me that everything is operating normally. However, they explained to me that the acceleration is now computer controlled and the computer is operating as intended. I insisted that this was a design flaw and that the computer should not question my decision to accelerate when ==> I <== want to accelerate. I was advised that there is no fix for this and that this is how it is. I purchased this vehicle new from a Toyota dealer. This problem has always existed.

The contact owns a 2007 Toyota Highlander hybrid. When applying pressure to the brake pedal, the engine would occasionally rev making braking more forceful. He speculated that the engine control system failed. The vehicle was taken to an authorized dealer for inspection. The technician stated there was no diagnostic testing equipment available to detect the malfunction. The failure mileage was 40,000. The current mileage is 42,000. Updated 02/1710 updated 02/19/10 updated 03/02/10 the consumer believed the problem was engine idle, not accelerating or braking. Updated 03/22/10. The consumer stated the problem he experienced was not due to a stuck accelerator, because the accelerator pedal also runs the hybrid motor. The hybrid motor is not accelerating the vehicle like the gas engine. If the gas pedal was the problem, the vehicle would still run away in electric motor. Therefore, it is definitely an engine problem, not an electric motor or electric generator. And it is something that controls the engine and the hybrid electric motor. Updated 04/09/10. The consumer stated he experienced sudden acceleration again. Updated 05/03/10

The contact owns a 2007 Toyota Highlander. While he was attempting to apply the brakes at 5 mph the pedal fell to the floor. The vehicle lurched forward over a stone ledge. The vehicle was taken to the dealership, but the technicians could not duplicate the failure, therefore they could not provide a remedy. The current and failure mileages were 18000.

My accelerator pedal got caught between my toes and bottom of my foot and the bottom of an open-toed shoe and I could not pull myself free to stop my car and I ran into a stopped car in front of me at an intersection, which was pushed into another car. I was traveling very slowly, but my activity in trying to free my foot caused my car to accelerate some. This had never happened to me before. When I told a neighbor she said the same thing had happened to her, but that she was not out in traffic at the time. I noticed that both of our vehicles have very narrow accelerator pedals, and that this could have happened to anyone. I have not been driving with sandals since then, but a great many people do.
