1 Service Brakes problem

Failure Date: 03/12/2023

Corrosion of pistons in front brake calipers results in an increase in braking stopping distance. Everytime the front brake pads are replaced the same issue is encountered, defect has taken place three times. In the four piston brake caliper the inside pistons on both the left and right caliper are frozen in place . The brake pads on the outside position have twice as much wear as the inside pads. This is an indication of uneven braking leading to increased stopping distance . Toyota maintains , there is not a problem, yet in forums on the web there are many experiences with owners having the same problem , resulting in costly repair bills. There is no warning of reduced braking efficiency .

2 Service Brakes problem

Failure Date: 11/24/2021

My 2006 Toyota 4 runner, I've found a large amount of rust through out the frame of the vehicle. I feel the vehicle is not safe to drive. Toyota has frame replacement recalls to the tundras, and sequias but not the 4runner. I feel this is an issue that Toyota is aware of. I also feel that something should be done for manufacturing a vehicle with defective chassis.

Corrosion related issues not found on other makes based on personal experience with other boxed ladder frame vehicles extreme corrosion involving disintegration of the rear trailing arm already haphazardly repaired with steel doubler ladder frame is disintegrating from interior of frame penetrating towards the exterior facade compromises structural integrity and safety of vehicle that is seen beyond on many 4runners beside this particular example brake calipers sticking due to corrosion requiring replacement on multiple occasions binding of brake components cause severe pull under highway speed braking.

4 Service Brakes problem

Failure Date: 09/13/2020

Just recently I have noticed that when I apply the brake pedal it "sticks" takes ( when driving) couple seconds to resume it original position and I can hear a click. I am taking it to my mechanic to ensure is not critical. Just wanted to know if there is a recall on this. Also, since approximately 2014 the original manufacture paint have gradually being deteriorating to the point which the whole body needs a new paint job. Specifically, the paint have completed faded on most parts of the body, the clear coat is completely peeling off. I am the only owner of this vehicle and I have taken good care of it, only 125 k registered.

5 Service Brakes problem

Failure Date: 12/03/2019

The frame is so rusted everywhere that it is unsafe to drive. One huge hole is completely broken through both sides of the frame and the bottom plate has cracked through. I have a highly reputable welding shop set to repair and patch this but I feel Toyota needs to take care of this before it costs me everything.

6 Service Brakes problem

Failure Date: 10/18/2019

The breaks pulse when your stopping and there have been two instances when I experienced the breaks unexpectedly went out or slipped. . . It's hard to explain exact feeling but it was scary. The traction control light came on when I was at a stop sign at a slight hill and the breaks made a strange noise this happened twice however the light only came on the one time. Then while driving the abs, traction, break, and another light all came on at once. This was just random while driving normally. About 20min later they went out. Also while setting at the light or being stopped while in great the car pushes forward while the break is depressed. These things fave been random when the breaks felt as if I had lost them I was turning a corner and stepped on the breaks while in the turn they made a slight noise and I let up when I felt as if I was losing them then depressed again. The second time it happened I was in a normal straight road and depressed the breaks and again it felt as if I had lost them. . . I jerked a little as it scared me being in traffic then I let up and depress them again and if felt normal. Again it has been totally random. Also my tire pressure light comes on quite frequently and I keep losing a little pressure in all tires.

Rusty frame, rusted brake, transmission lines.

8 Service Brakes problem

Failure Date: 09/07/2016

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.

9 Service Brakes problem

Failure Date: 04/21/2013

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.

11 Service Brakes problem

Failure Date: 05/04/2009

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.

12 Service Brakes problem

Failure Date: 08/10/2006

We own a 2006 Toyota 4runner - during the first year we took it in three times and told them that when we are at a stop the SUV would shift fwd while still applying the brake. We took it back again the 2nd year, still with the same complaint. Each time they had no answer as to what the problem was cause they could never get the problem to repeat. To date the SUV still does it and would say at least once every two days so much so we have just become used to the problem.

13 Service Brakes problem

Failure Date: 01/01/2006

Starting at this date: its happened 4 times since while driving when needing to apply my brakes suddenly. I apply the brakes, medium hard tension, opposed to jamming on the brakes, then momentarily let off brakes and then taped brakes to more gently ease off the situation. The car then bucks violently as if hitting something. Extremely shocking. One time I had a passenger and as she was shocked too, asked me what I was doing? I replied, "nothing, the car did it! I read online that others have experienced the same issue I describe.
