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.

Frame rot excessive rust on frame, compromising the integrity and putting the passengers lives at risk if the frame should fail. Contacted Toyota, they informed me that no recalls or service campaigns are available for frame rot on 4runners, however Tacoma, sequoias, and Tundra have had frame rot recalls. Very unhappy as to how this matter is being treated especially after all the other frame issues from Toyota vehicles.

Purchased a tcuv in 2012 and live in eastern nc. Took vehicle in for diagnostic and was told that frame was severely rusted. Was not made aware when purchased. Called Toyota and awaiting a call but rep says that its out of warranty and will not assist. Vehicle can't go from fine to severe in 3 years and was certified by Toyota to be fine or "like new". something has to be done and a recall has to be issued. This is an ongoing issues that many individuals are experiencing and a severe safety hazard should something go wrong on the freeway. No one should have to die before something gets done and it would be in poor taste for this to happen before this complaint moves from its current status to investigation by our government to protect us from companies like this.

I am the original owner of this vehicle and have kept this vehicle in excellent condition. I have spent lots of money on routine maintenance of this vehicle as well as more involved tune-ups. I have also washed this vehicle regularly including the underside of this vehicle, especially during the winter months to clean off road salt. There are no existing mechanical or other problems with this vehicle and can potentially drive this vehicle for many more years to come. However, during a routine visit to my local Toyota service center, I was told that there exists a large perforation on the frame of this vehicle due to rust. I was further told that this frame perforation makes this vehicle unsafe to drive and was instructed not to use this vehicle since it could result in a deadly situation for the occupants of this vehicle if the frame broke (which I was told will happen) while driving. I am now unable to use this vehicle due to safety concerns. I called Toyota hq to complain, but they told me that they cannot help me and that my vehicle is out of warranty.

The frame rust on my 2006 4runner is becoming extensive and the amount for the year that can become potentially dangerous in the near future is inexcusable quality at best. There are areas on the frame that I am able to push in with my fingers because of the rust. There are also other parts where other parts that have been bolted on to the frame or welded on have completely rusted off. I am able to in spots peel the frame apart piece by piece like an onion only exposing the ridiculously thin amount that is left. I have a 2003 Chevy pickup that drives in same conditions as the 4runner and looks years newer underneath than the 4runner that is actually the newer of the two. I would like to make it known that frame rust from other research regarding these vehicles as well as my own is something worthy of a Toyota recal or buy back program such as what was done with other generation Tacoma.

The contact owns a 2006 Toyota 4runner. The contact stated that there was an extensive leak of an unknown fluid under the front of the vehicle. The vehicle was taken to the dealer. The technician diagnosed that the hydraulic system needed to be replaced. Also, the vehicle was taken to an independent mechanic for a second opinion who diagnosed that the suspension system needed to be replaced. The manufacturer was made aware of the failure. The approximate failure mileage was 109,000.

I had a 2006 Toyota 4 runner, limited. The brake system never was right and that is why we got rid of the car. At a light, car would continue to inch forward. I complained to the dealer several times and when it lurched forward when stopped in a school zone this past spring, we immediately got rid of it, since the dealer kept telling me nothing was wrong.

Not until I read the article on yahoo (inside Washington missed signs in Toyota recalls) did I realize I do have a problem with my 2006 Toyota 4runner. My 4runner constantly lurches foward as I have my foot on the brake in a stopped postion. I always thought it was just the way the truck was made since it was my first Toyota. Now I realize what the problem is. But how do I get it fixed? I do not see the 4runners as having the recall on them.

I was coming into dewitt Arkansas on highway165 on 12/13/09 at about 12:30pm with my cruise control on at about 60 mph. I tapped the brake to disengage the cruise control and slowed down to make a right hand turn into an exxon MINImart. My 2006 Toyota 4runner suddenly accelerated as I attempted to stop near the front door. As I applied pressure to the brakes I heard the anti lock brakes clicking and suddenly the 4runner lunged forward striking a large pole that was in front of me. The rear wheels were spinning wildly and the back end was bouncing up and down. The 4runner was bouncing to the side and I slammed the shift lever into park. The power to the back wheels stopped. I sat back and took my foot off the brake pedal, then I noticed that the engine was still running wide open throttle. I reached up and turned the key off. I looked at the floor mat and it was in its normal location with no contact with the gas pedal. The two hooks were attached holding the floor mat in place. There was no way it could have been involved. Two employees came out and asked if I was okay. I told them I was okay, but scared to death. I told them I had heard about Toyota having a sudden acceleration problem, but I never thought I would be involved in one. I had to walk around a while to calm down. I got the employees names and phone numbers in case I needed them. I went back outside and started the 4runner up again and it ran normal. I drove it to my dad's and left it there. I called the Toyota dealer the next day and had them come pick it up. The dealer had a local technician check it out. They said they could find nothing wrong and said I should come and get it. I told them that was unacceptable. They had a regional specialized field technician evaluate it. He said that there was no safety hazard with my 4runner. The dealer wants me to come and get the vehicle. Nothing has been fixed or repaired.
