A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single

Recalls on the 2021 Toyota 4RUNNER
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

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.

SERVICE BRAKES
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.

On 3/30/21 it was discovered that my 2021 4runner with 5500 miles caught fire while parked in my enclosed garage. This event happened while my family and I were sleeping. The fire was discovered @5am at which time the fire department was contacted. The fire was contained to the garage. The vehicle was a total loss and was determined to be the source of the fire that destroyed all of the contents in my garage and significantly damaged the garage structure resulting in a rebuild. The fire department performed an initial investigation, a 3rd party fire investigator performed an investigation, and State Farm along with a representative from Toyota conducted an investigation. Per my claims adjuster, the investigation determined that the fire originated in the vehicle but the exact cause could not be determined due to the damage to the wiring harness and the proximity to the condenser. This incident could have easily lead to significant injury or death to my family. The vehicle had not experienced any issues, no warning lights had indicated an issue, and the only maintenance that had been performed to the vehicle was a tire rotation at 5000 miles at the Toyota dealership.

STEERING
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.

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.

ELECTRICAL SYSTEM
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.

SERVICE BRAKES
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.

POWER TRAIN
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

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.

TIRES
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.
