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.

Takata inflators, ABS. Purchased vehicle used 08/12/2016 the following mil codes were cleared by selling dealership. C1223, P0456, B1150, CR123, C1241, B1152. Needed repair immediately, passed state inspection even needing the following repairs, both front axles, serp belt, sway bar link and rear brakes.08/24/2016 vehicle repaired by selling dealer and returned with flat tire, I had it towed to tire garage because spare was too old and incorrect size. After I picked up from tire repair I made an appointment for an unrepaired safety recall from 2012 on the ABS at a local dealership. Prior to service appointment I was driving over a speed bump and the vehicle would not drive over bump, ABS lights came on and vehicle rolled backwards. Had towed to Toyota dealer for service(I have receipt for tow) a couple days later dealer said recall was completed but would not provide any documentation for repairs. That dealership broke a lug stud on the front tire in but did not repair it. They said its ok to drive on 5 lugs its a 6 lug rim. I then brought the vehicle to another Toyota dealer for repairs because the vehicle started rolling backwards on inclines and not accelerating. Very scary because I almost rolled back into cars, also tire pressure light was on but all tires were inflated. They had it from 09/12/2016-09/26/2016. Unfortunately could not duplicate concern but did repair the lug stud, tire pressure sensor and recalibrated the ABS and airbag light(I was not informed until picked up about the airbag). I also had an oil change. Vehicle having issues as of today right turns I hear a loud clunking sound and wobble when hitting bumps on highway speeds.. the ball joints might be bad. I can see them covered in grease and have play. I am concerned that the vehicle is unsafe and was in an undisclosed major accident prior to purchase. Next app is not until 10/24.

I have a 2006 Toyota 4 runner that has been developing excessive rust flaking on the rear axle housing, brake components, frame and rear suspension componets.we have had warranty work performed approx. 1 year ago and the mechanics at Toyota stated they needed to replace or repair various transmission lines before they would return the vehicle to my wife. I asked them what am I suppose to do about all the rust problems and they really didnt have a answer and said I need to talk to the service manager that was not there at the time. I have made every attempt to radicate this issue that has been getting worse over time. Vehicle is garage kept and was purchased new as we are the only owner of this vehicle. Myself and everyone else know Toyota knows about this problem and refused to do anything about it. My fear is that we are on a trip and have catastrophic failure of one or more components and getting in a accident. There was no accident yet.

The contact owns a 2006 Toyota 4runner. The contact stated that while having routine maintenance performed, the technician stated that the pistons were frozen and the front brake calipers needed to be replaced. The vehicle was repaired. The contact stated that the front brake caliper was replaced once every year from the date of purchase. The manufacturer was notified of the failure. The failure mileage was 45,000.

The pistons in both front calipers have frozen up and had to be replaced twice. The first time at 90,000 miles and again at 160,000. Many forums on the 4th gen 4runners document many people others having had the same problem. I asked the dealer and they said that it was not a problem they were aware of. This seems to be a design/factory defect. It is very dangerous.

Coming to a stop sign at about 30 mph I applied brakes at normal pressure. There was a loud snap and car suddenly veered hard left. Took it to service center for evaluation. The front right rotor was broken. The disc had separated from the hat. Service center replaced both front rotors and inspected all brakes, on July 24th, the same thing happened with the front left rotor, which is only a few months old. Something very dangerous is wrong with the brake system on this vehicle that is actually breaking the rotors. If this were to happen at higher speeds it could cause complete loss of control of the vehicle.

We were stopped at a stop light at the time of the incident. An alarm went off in the car and the red brake light came on. At that point we rolled the car to see if the brakes were working. This is when we realized there were no brakes and the only break we had was our emergency brake. It was taken to a nearby mechanic where it was determined that a caliper over-extended causing the brake fluid to leak out- losing the hydraulic brake system all together. Luckily we were not moving at the time of the incident because having lost the entire break system while moving could have been extremely dangerous.

Driving in rain on freeway connector road, 25 mph, required to use brakes due to another driver illegally swerving from slow lane of freeway adjacent to connector road, across two solid lines, in front of a car that hit their brakes, and was rear-ended by a second car, which was in front of me. I had plenty of distance to stop, but when I stepped on my brakes, they instantly locked up and my 4runner immediately began to control at all to slow down, and it felt like I actually increased speed. I know what ABS feels like, and my brakes are new, installed in July 2012 at a Toyota dealer service dept. This ABS system failed! no pulsating feeling, nothing but locked up brakes, which resulted in my hitting the car in front of me. The truck that made the change, and was almost 90 degrees to the lane we were in then took off. He was not hit, but I chased and caught him for chp. My 4runner is crushed because of an idiot, and the failure of my ABS to properly function. I have been safely driving 44 years.

I brought my car in for regular service and new brake pads and rotors. I was told one of the brake calipers on the front wheels was frozen. If the brake caliper is frozen, then the car has significantly reduced stopping power. There was no engine light indicating the problem. Multiple people have complained about calipers on the 4 runner. Please conduct an investigation and seek a response from Toyota.
