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.

I have a 2004 Toyota 4 runner, which I believe is not subject to a recall, and on three occasions the accelerator has become stuck. Each time it occurred when I accelerated more than normal, and each time once my foot went off the pedal the car kept accelerating. Each time I was able to stop it by braking. Two of the occasions occurred back to back less than a minute apart. I am somewhat afraid to drive the car and certainly afraid to accelerate hard. There was a floor mat and I have removed it.

I have a 2004 Toyota 4-runner. About 2 years ago as I was driving down a local highway at about 45 mph, my 4-runner suddenly took off as if the cruise control engaged. However, the cruise control was not on. This is the one & only time this happened. I feel like this incident should be noted since Toyota has not recalled any 4-runners. Maybe there have been other similar complaints on the same vehicle as mine.

4Runner

  • 40,400 miles
The contact owns a 2004 Toyota 4runner. While driving approximately 5 mph into a parking space with her foot on the brake pedal, the vehicle accelerated on its own without warning. She applied extreme pressure to the brake pedal; however, the vehicle failed to stop and crashed into another vehicle. The front end of the vehicle was damaged and repaired. The mechanic test drove the vehicle, experienced the failure and advised the contact that they would not release the vehicle since it was too dangerous to drive. The dealer was notified and advised the contact that an inspector within their legal department would diagnose the failure since it was involved in a crash. The failure and current mileages were 40,400. Updated 03/04/10

4Runner

  • 78,000 miles
I have a 2004 Toyota 4runner and a few months ago the accelerator pedal got stuck under the rubber floor mat. I purchased the rubber floor mat from a Toyota dealer and it was made specifically for the 4 runner. When the pedal got stuck, the engine was running wide open. I managed to get the vehicle in neutral and stopped before hitting anything. It was very frightening. It appears like the mat slid forward and that was what caused the pedal to get stuck. I had recently cleaned the mat and may not have had it positioned properly when I reinstalled it. I think the design of the mat is not safe due to the thickness of the mat at the front near the pedal. Future incidents are likely if the mat is loose and slides forward. I did have a carpeted mat under the rubber mat. The carpeted mat came with the 4runner when I bought the vehicle. This likely contributed to the rubber mat coming loose and sliding forward. If not installed properly, it appears like the carpeted mat could also slide forward and may cause the accelerator to get stuck.
