EVIDENCE, NOT A SCORE
WHAT THIS DATA CAN TELL YOU ABOUT RELIABILITY
Official records can provide useful research context, but each source has a different meaning. Complaint counts are not failure rates; recalls are formal safety campaigns; manufacturer communications are technical or service documentation; and investigations reflect formal NHTSA activity. Data Confidence measures evidence availability, not vehicle quality. CarIQ does not publish a composite Reliability Score.
Available evidence summary: 36 NHTSA owner complaint records; 1 safety recall campaign; 0 manufacturer communications; 0 applicable NHTSA defect investigations.
EVIDENCE AVAILABILITY — NOT VEHICLE RELIABILITY

NORMALIZED COMPLAINT CONTEXT
Production-normalized complaint data is not currently available for this vehicle.
This metric compares the number of NHTSA owner complaint records retrieved by CarIQ with NHTSA-reported production volume for the corresponding vehicle population.
It is not a vehicle failure rate. Complaint reporting behavior, vehicle age, time on the road, production definitions, and other factors can affect the result.

OFFICIAL NHTSA OWNER COMPLAINT DATA
PROBLEMS REPORTED IN NHTSA RECORDS
CarIQ groups available NHTSA owner complaint records for the 2021 Toyota 4Runner by vehicle system to make recurring documentation easier to research. Most represented complaint categories describe the retrieved records—not failure frequency.
MOST REPRESENTED COMPLAINT CATEGORIES
A complaint may list more than one component and therefore contribute to multiple categories. Percentages show the share of categorized complaint records that mention each component—not the percentage of vehicles affected. Category percentages may overlap.

RECENT OWNER COMPLAINTS
Steering
Owner-submitted NHTSA complaint · ODI 11761925Read complaint narrative
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.

Steering
Owner-submitted NHTSA complaint · ODI 11741081Read complaint narrative
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.
Service Brakes
Owner-submitted NHTSA complaint · ODI 11722616Read complaint narrative
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.
Back Over Prevention
Owner-submitted NHTSA complaint · ODI 11712755Read complaint narrative
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.
Back Over Prevention
Owner-submitted NHTSA complaint · ODI 11707218Read complaint narrative
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.
Fuel/propulsion System
Owner-submitted NHTSA complaint · ODI 11704362Read complaint narrative
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.
NHTSA complaints are reports submitted by vehicle owners and other consumers. Complaint counts do not represent the percentage of vehicles affected and do not by themselves establish that a safety defect exists.
A higher complaint count can partly reflect how many vehicles were sold, vehicle age, and other factors. CarIQ does not yet normalize complaint counts by vehicles sold.

OFFICIAL NHTSA MANUFACTURER COMMUNICATION DATA
MANUFACTURER COMMUNICATIONS
No NHTSA manufacturer communication records were returned for this year, make, and model.
Manufacturer communications include service bulletins and other technical information submitted by manufacturers to NHTSA. The existence or number of communications does not establish how often a condition occurs or whether an individual vehicle will experience it.
Some manufacturers may issue more detailed service documentation than others, so communication counts should not be used alone to compare vehicle reliability.

NHTSA DEFECT INVESTIGATIONS
No applicable NHTSA defect investigation records were returned for this year, make, and model.
NHTSA investigations evaluate potential motor-vehicle safety defects. The existence of an investigation does not by itself establish that a safety defect exists, and the absence of an investigation does not establish that a vehicle is problem-free.
Open and closed describe NHTSA's process status, not a CarIQ reliability judgment.
