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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

CarComplaints.com Notes: Although it has a stellar record in terms of vehicle problems, initially the 4th generation (2003 - 2009) 4Runner didn't earn our top "Seal of Awesome" rating because it received poor crash test ratings for rear impacts. However it's proven to have one of the lowest driver death rates out of all vehicles (not just SUVs), so we've bumped it back up to our top award.

Sudden unintended acceleration occurred in our 2008 Toyota 4runner. While sitting in a turn lane, foot on brake, transmission in drive, the vehicle engine suddenly increased power dramatically on its own. With foot on brake the vehicle accelerated forward on its own. It continued forward for about 800 feet before it returned to normal. No damages or injuries. Vehicle was parked and Toyota dealer came and got it. Said they will run tests. This was not a imagined event. This is our second 4runner model and we have had no complaints with the vehicle until this incident. Additionally, I note that this vehicle is not on Toyota's current recall list. There is nothing Toyota can say or do that would restore my safety confidence in this vehicle after this incident. Thus, we will trade it in on another brand once we get it back. I would like for NHTSA to consider requiring Toyota to put this vehicle model on their recall list. Even one defect of this nature is unacceptable. Also 10328962 smch

Started my 2008 Toyota 4runner. Never touched the accelerator pedal. Engine raced uncontrollably to around 7-8000 RPM and shuddered terribly. Immediately turned the engine off and then tried it again. Did same thing. Took vehicle to the dealership where they said they couldn't duplicate the symptoms and said there weren't any codes stored in the computer. Was told they would call Toyota technical to report issue. Never have been contacted. This incident only reinforces the belief that Toyota has issues other than the "recall fix". I believe that it is an electrical/computer problem. It should be noted that my vehicle is not even on the recall list.

I was in the smoky mountains in Dec 2009-Jan 2010 where the temperatures were very low and the vehicle was outdoors. Temps were mid 20S in the day time and mid teens at night. No icing was an issue. I was driving my 2008 Toyota 4-runner into a parking space slowly around 2 pm getting ready to apply the brakes. Before I could do so the vehicle took off. I immediately slammed on the brakes and the vehicle did stop, however it had traveled approx 10 ft before I could do so and it slammed into a tree. I owned a new 2003 4-runner and never had this happen. I bought this vehicle in Jan 2008 new. This is the only time this has happened. This crash resulted in $1768.35 in damage. I took the vehicle to a Toyota dealer and they removed my all weather mats. (I inspected these immediately after the accident and they were in place as they should be locked down) Toyota set up an appointment and looked at the vehicle at the dealership and sent a letter that stated "no system failure was found in either the braking system or the accelerator system" they further stated that "the fact your vehicle is not included in the current safety service campaign involving floor mats/unintended acceleration would indicate that this incident was not the result of this issue." "?? if not what is the issue..cruise control computer " the dealership stated that the only vehicles affected were made in the usa and my vehicle was made in Japan, therefore it was not having a problem. What happens next time and I go off a cliff. We need some answers. I don't know what to do. I spent alot of money on this vehicle and I am not sure it is safe and if I sell it I stand to lose enough money to keep me from buying a vehicle of equal value. We need to put our foot down and make them solve this. Thank you NHTSA.

I own a 2008 Toyota 4runner. I know it is not on the recall list, but a year ago I had an accident that fits the description of the sudden accelleration. No one at the time believed me when I said that I did nothing wrong, that the car just took off. In February 2009 I was on my way to work at around 6 am, everything was good. Then the next thing I remember I felt the car go over a curb and run into a building. The damage was great to the vehicle. The speed limit was 35 miles/hour. I remember pressing on the brake, but it had no effect. I was charged with careless driving, had to pay to fix the building and my car, and I now also have higher insurance cost. This happened in florence SC.

  • Automatic transmission
  • 16,000 miles
The contact owns a 2008 Toyota 4runner. The contact stated that the vehicle accelerated unintentionally while driving 50 mph. She had to depress the brake pedal with such force that she destroyed the entire braking system. The dealer had to replace the entire braking system because the brakes were so hot that they destroyed the rotors and the pads. The vehicle is still at the dealer and the contact does not want to pick it up. The VIN was unknown. The failure mileage was 16,000.
