Body 2

While vehicle was parked and not in use, upon entering the vehicle, the steering wheel/column dropped out of its locked position on its own. Disassembly of the steering column revealed that the tilt-lock mechanism's steering lock fracture bolt has broken in half on the right side. This cause the steering wheel to fall out of a locked position and allowed the entire column to rotate skewed to the left side. The steering wheel became dangerous to use as it was in a freed position that allowed the entire column to move while providing inputs into the steering wheel. Had this occurred while the vehicle was in motion, it could have caused a sudden loss of steering control and significantly increased the risk of a crash or injury. The problem was confirmed by an independent mechanic upon teardown of the steering column, who visually verified the broken fracture bolt and the resulting free movement of the column. There were no dashboard warning signs, error messages, or noticeable symptoms prior to this event. The column simply came loose and dropped when entering the vehicle after it had been parked. The vehicle had about 120,000 miles at the time of failure.

The power door lock actuators on both front doors of my 2021 Toyota 4Runner have failed. The problem developed progressively. The front door locks initially began working intermittently and became less reliable over time. Eventually, both front door lock actuators stopped operating. They have now been inoperative for more than six months. The front doors will not reliably lock or unlock using the vehicle's power locking system or key fob, while the rear power door locks continue to operate normally. I discussed the problem with a Toyota dealership and was told by dealership personnel that they have seen this door lock actuator failure happen countless times. Despite the apparent frequency of the problem, I am not aware of a recall covering my vehicle. I am concerned about the safety implications of multiple door lock actuators failing prematurely. The failure prevents the vehicle's power locking system from reliably securing or unlocking the front doors and could cause difficulty quickly unlocking a front door for a passenger or occupant in an emergency. There were no warning lights or dashboard messages before the failures. The primary warning was the progressively intermittent operation of each front door lock before it stopped functioning entirely. Both front doors experienced the same progressive malfunction. I am reporting this because the failure has affected multiple actuators on the same vehicle, has persisted for more than six months, and a Toyota dealership indicated that it has encountered this problem many times.

I just had the tires road force balanced on a haweka with lug-centric balance, and the steering wheel persists shaking from 55-65 mph. From what I have seen is this is a design flaw on this generation of 4 runners called the shimmy. For a newer vehicle this is not only dangerous, but unacceptable to not be considered for a recall when it is this widespread.

Brakes 2

Today while I was driving home from work, in a snow storm, suddenly a low braking power notification and ABS malfunction popped up on my console with loud beeping and my brakes completely stopped working. In order to avoid hitting the car in front of me I had to swerve to the shoulder and come to a stop.

My backup camera does not work consistently. It will sometimes come on and show objects behind me; other times it is a black screen. I have read where Toyota models from 2022 to newer, but not including the 4 Runner, are having major issues with the back up camera and are under recall. I believe this recall should include the Toyota 4 Runner, as mine seems to be having issues which affect my safety and others. I called the nearest Toyota dealership to verify if my car was under recall and they said no. I have not taken the vehicle to be inspected by the dealership. This issue started about 6 -8 months ago. No lights or warning messages appear on the dashboard. I thought maybe my camera was dirty, but wash the car and it still is inconsistently working. It fails more than it works.

Body 4

Rear backup camera has been failing or intermittently working, it is available for insp[ection upon request. This has created a situation upon reversing in driveway where I expect it to be on and dont see a vehicle or trailer behind me. I have hit a parked car because I was expecting it to work as I check rearview mirrors. This is now a habit and I did not realize it wasn't working at the time until i collided with the vehicle. The dealership will not confirm it or inspect it unless payment is rendered. No one has inspected it except for Virginia. Which I am unsure that is even something they inspect. They may have just inspected other things that allow for use on highway. No lamps or other warnings when it began in april 2023. I have not tried to get it fixed as this is a new vehicle and I wasn't willing to pay the dealer to diagnose and most likely decline my warranty coverage.

Vehicle was diagnosed from a mechanic with no fuel pressure due to not starting. Vehicle has approximately 135,000 miles and had no warnings or indications of problem. It appears when VIN was ran on gov. recall that Honda had issues with fuel pump. Vehicle will be inspected by Toyota dealer.

Several door lock actuators have prematurely failed. The first to do so was front passenger door in summer 2024; front driver door lock failed a few months after. Most recently, approximately 4 months ago, the lock actuator for liftgate failed. This poses safety hazard in easily exiting vehicle and/or entering it if in dangerous situation. I have been communicating with local Toyota dealership for months about repairing these defective items, They have acknowledged awareness of an issue with the actuators, but have offered no help. I have read there is a class action lawsuit pending about this issue. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Saturday morning July 12th after starting my vehicle, a warning was presented “SRS AIRBAG SYSTEM MALFUNCTION”. I immediately took it to the dealership where they ran diagnostics. The service advisor admitted he nor his mechanic had ever seen anything like that before. They were unable to detect the issue that day. We planned to return the vehicle Thursday July 17. I dropped it off at 10am and never heard from the dealership again that day. Friday, July 18th I contacted the service advisor around 10 am to get an update in which he said they were looking into it. Friday afternoon, I received a call from the service advisor letting me know that the front passenger Occupant ECU had malfunctioned, costing approximately $1000. After researching this, I learned that Toyota has issued many recalls on this issue with other models. I called Toyota headquarters to see how they would rectify this but ended the conversation with no solution other than it is the consumer’s liability. This is a safety issue that should fall back on the manufacturer, especially given the history of recalls issued on this specific defect.

Brakes 2

My brakes and rotors are requiring replacement after less than 10,000. I purchased my vehicle used with less than 15,000 miles. My brakes and rotors have been replaced three times in the last 45,000 miles. The dealership denies any malfunction or error with the breaking system. I have seen multiple complaints online from other 4Runner owners with the same issues. My vehicle has less than 60,000 miles and I commute 5 miles a day to work on surface streets. I do not take it off Roading. I do not tow. I drive 5 miles to work and 5 miles home. I have been driving for over 30 years and have never had to replace brakes and rotors every nine months. Right after we purchased the vehicle, we brought it in saying the brakes did not feel right. My husband thought they needed to be adjusted. We were told the brakes are hydraulic brakes and do not require adjustment. But the brakes have felt off since we first got them. Toyota service insist that they have inspected the vehicle fully and have found no issues.

Transmission 2

As the vehicle was traveling on a highway at 35 mph the vehicle shut off electronically three times and powered itself back on after 15 seconds or so of continuous cruising on the highway. Unable to accelerate or control the vehicle while the electronic component shut off in the vehicle. Three days later, a series of warning lights and check engine lights turned on, which has occurred 6 other times, and has been brought to local Toyota dealer multiple times (over six times) and no fix has been conducted to repair the vehicle other than resetting the vehicles ECU. When all of the warning lights turn on, the vehicle loses 2nd gear and juts itself forward and becomes extremely difficult to control to the point where I have almost gotten into life threatening accidents over 4 times. Toyota has acknowledged that they do not know what is wrong with the vehicle and is unsure how to fix it. This is a safety concern that is not getting enough attention and needs to be rectified before someone or myself ends up killing ourselves

TRD PRO MODEL Clunk at low speeds. FOX shocks on TRD PRO make clunking sound at low speeds. Toyota replaced 3 shocks under warranty. The 3rd one they charged me labor but covered the shock. Car has highway miles and very little time spent off road as I live in NY. As of today clunking is back in full force. Seems to be an ongoing problem if you google clunking fox shocks Toyota TRD 4Runner.

While pulling this vehicle in to my garage about halfway in the brake pedal went to the floor and the vehicle hit a bench on the opposite side of the entrance. After pumping the brakes after waiting about 10 minutes they seemed to work normally. I backed the vehicle out of the garage and saw NO fluid under the vehicle. The next morning the vehicle was towed the the dealer collision shop and then taken to the service department at the dealer. This problem; ,after almost 2 months was never solved....corporate offices checked the data recorder...no conclusions.....and implied this problem did not occur. The body is now being repaired yet no brake problem has been ever repaired. ( under warranty....31,967 miles ). I understand a similar problem occured in New Jersey although on the road and the driver had to be removed through the sunroof and the vehicle was totaled.

I have a Toyota 4runner 2021. I'm actually presenting steering wheel shake and a feeling of unstable suspension issues in the front end during highway speeds more than 60 MPH. I when to the dealership and they align and balance the tires. But problem still happens. They said that not problem has been found when they verified the vehicle but they noticed the issue.

I purchased the vehicle from a Dealer. During a test drive I noticed a shake in the steering wheel that represented a wheel balance issue. The dealership acknowledged that, according to their techs that it was a wheel issue. A new set of tires was ordered mounted and balanced. I have been dealing with the issue of sometimes excessive steering wheel shake and a feeling of unstable suspension issues in the front end during highway speeds of 60-70 MPH. In researching this model of Toyota it appears this is a well documented problem that has not been addressed by Toyota.

At speeds above 45 miles and hour, the steering wheel begins to nibble / shake which creates an unsafe driving situation. Vehicle has had alignment performed, and new tires balanced which still has not resolved issue.

Yokohama 245/60r20 Geolander G96 that came with my brand new 2021 Toyota 4Runner Limited I purchased in December 2020. Over the last several weeks every 7 to 10 days I have needed to put air in all 4 tires. Then I was driving on a smooth paved street arriving at work my low pressure warning light came on. I got out and had a flat tire. I found the inner sidewall failed at only 28,000 miles. I didn’t hit anything on the road, or hit a curb etc. just normal driving on paved roads. Putting on the spare I took my 4Runner to the Toyota dealership a few miles away. The service technician at our local Toyota dealer today stated they, “are seeing this issue as a common problem with this particular tire on Toyota 4Runners in our Colorado Cold climate, is causing the rubber to become excessively brittle. Even with normal use, the smallest stones/sand used in our highway plows/sanding trucks cause catastrophic premature tire failure. They may be fine for use in California warm clients but not here in Colorado.” This explains why recently every 7 to 10 days I have needed to put additional air in all 4 tires. The rubber is prematurely becoming brittle/rot in cold weather thus not properly sealing the air. The technician recommended going with 4 new tires from a different manufacturer, stating the problem will continue with the other 3 Yokohama tires and likely a new Yokohama tire as well. He agreed the tire should be recalled as this is unacceptable especially for a tire with a M+S (mud and snow rating), only 28,000 miles on and properly taken care of. At $400+ per tire this is a huge expense and clearly a HUGE safety issue in cold climates. In cold weather having to refill tires with air every 7 to 10 days is a real hassle as well. Good thing I have my own air compressor at home. I only drive with the correct air pressure per my owners manual as stated on my drivers door. The Toyota dealer drew a white chalk square around the tire failure area.
