TIRES
Purchased size 265/70R17 tires (Michelin Defender LTX M/S2) exhibiting severe highway vibration immediately post-installation. The vibration persisted continuously for two years across every rotation, posing serious handling and steering risks. For two years, local shop staff gaslit the customer, claiming an "out-of-round" tire or casing defect was impossible to avoid warranty obligations. During a visit in front of store management, staff repeated the claim in front of management. The customer then presented real-time technical data from Google on the spot, forcing staff to admit casing defects happen. Despite this, management cleared the driver to leave, assuring the vehicle was safe to operate with an infant inside. To obtain objective proof, an authorized TOYOTA dealership inspected the vehicle. The dealer verified steering, suspension, and alignment were completely sound and documented the root cause in writing: "Found front left tire has casing deformation." When escalated to corporate executives—including Robert Moyer and top management—an internal email chain revealed local shop management and corporate leadership actively placing profit over safety, contradicting logs and technical facts to deny warranty coverage. Confronted with dealer documentation and caught in their deceptive paper trail, the company fully refunded all tire replacement and balancing costs. Internal casing deformation is a critical safety hazard; belt/casing failure at highway speeds creates extreme risk of sudden tread separation or blowout. Dealership diagnostic documentation and the deceitful Executive email chain are available upon request. I also have video of shaking while on the freeway with my infant child in the car moments after Costco management assured me we were safe.

LATCHES/LOCKS/LINKAGES:ELECTRONIC LOCK/LATCH ACTUATOR
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.

POWER TRAIN, WHEELS, UNKNOWN OR OTHER
**Vehicle:** 2026 Toyota 4Runner SR5- -700Miles I am reporting a persistent vibration issue that appears to come from the engine bay and is transmitted through the driver's side floorboard into the driver's left foot and leg. The vibration is most noticeable when the transmission is engaged and the vehicle is under load. If the transmission is disengaged while the vehicle is still moving, the vibration disappears, even though the driveshaft, axles, and other drivetrain components are still rotating. This suggests the issue may be related to the engine or transmission rather than the tires or other rotating components. My daily one-way commute is approximately 30 minutes. By the time I arrive at work, I experience a noticeable vibration sensation in both feet, especially my left foot. The sensation continues for more than an hour after driving and is concerning enough that I believe it could have health implications if the issue continues over time. I have found reports from other owners describing similar vibration concerns, which suggests this may not be an isolated incident. I believe this issue deserves investigation because continuous vibration transmitted directly to the driver's foot and leg can affect driver comfort and may have potential health and safety implications during extended driving. I respectfully request that NHTSA review this complaint and determine whether this condition represents a broader vehicle defect requiring investigation.

ELECTRICAL SYSTEM
I am a fire investigator for the Olathe (KS) Fire Department. On July 3, 2026 at 1255 hrs our crews were called to a vehicle fire for the above listed car. The vehicle was reportedly being driven when smoke entered the passenger compartment causing the driver to pull over. He opened the rear tailgate and saw flames coming from the base of the rear cargo area. He called 911. Olathe PD utilized a fire extinguisher and Olathe FD units extinguished the fire. I responded to conduct an origin and cause investigation. I determined that the fire originated at/near the battery/electronics bay of the rear cargo area. I did not conduct any destructive testing. The driver reported that this is a loaner car from the dealer while his vehicle is being serviced. There was no evidence of vehicle collision or other mechanical problems. The driver did not report noting an vehicle issues prior to the smoke.

STEERING, LANE DEPARTURE: WARNING, LANE DEPARTURE: ASSIST
The LKA system steers the vehicle into the oncoming lane of travel under specific and repeatable conditions. The defect occurs as follows: While the vehicle is traveling and the LKA system is following the left lane marking, the vehicle approaches a marked left-hand turn lane or turnout where no fog line is present on the right-hand side of the road. In this situation, the system abruptly attempts to steer the vehicle toward the turn lane. Because the turn lane is positioned to the left of the driver’s actual lane of travel, this steering input pulls the vehicle toward and into the oncoming lane of traffic. This steering intervention happens without warning and without any input from the driver. Given that it moves the vehicle into a lane carrying oncoming traffic, it presents a direct risk of a head-on collision. Manufacturer Response I contacted Toyota regarding this issue and was told that this behavior is normal, and that the system will use whatever lane marking is available to determine its steering path. Toyota did not indicate that a fix or software update was planned. I do not consider “the system follows whatever line it has” an acceptable explanation for a feature that actively steers a vehicle into oncoming traffic. Why This Is a Safety Defect 1.The system takes an abrupt steering action with no driver input and no warning. 2.The result of that action is movement into a lane used by oncoming traffic, which is the most dangerous possible outcome of a lane keep assist malfunction. 3.The condition that triggers this behavior (a marked left turn lane with no right-side fog line) is common on ordinary two-lane roads and is not something a driver can always anticipate or avoid. 4.The manufacturer has acknowledged the behavior exists and has characterized it as expected operation rather than a defect.

ELECTRICAL SYSTEM, FUEL SYSTEM, GASOLINE, EXTERIOR LIGHTING
The contact owns a 2025 Toyota 4Runner. The contact stated that the message “Headlights On” was erroneously displayed. The fuel gauge indicated 71 percent. Additionally, the 12-volt charging system malfunctioned with the message “See the Dealer” displayed. Several unknown orange warning lights were illuminated. The vehicle was restarted, and the warning lights turned off. The window on the passenger’s side was violently shaking. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure, but an undisclosed software was reprogrammed. The vehicle was taken back to the local dealer, where it was diagnosed and determined that the fuel pump was replaced. The vehicle was repaired. The dealer was contacted and informed about a diagnostic test. The manufacturer was contacted, and a claim was filed. The failure mileage was unknown.

The driver’s side window rattles in its tracks when open 2-3”, and when all the way down. Any rough roads will induce the rattle. Toyota master technician has confirmed the rattle in my vehicle and a new 4Runner, which displays the same problem. It appears to be a defective design.

Traveling on highway with no other cars anywhere around. Going 80 mph on an 80 degree day when sun roof on 2025 Toyota 4 runner exploded. Sun roof was closed at the time, but could have had devastating consequences if it had been open. Toyota rep did not take a look at the broken glass to check for imperfections or manufacturing issues, just told us we needed to make an insurance claim.

ENGINE, FUEL/PROPULSION SYSTEM
We were traveling north on hwy 23 in southern Minnesota pulling a 5000 lb trailer in the rain and it was windy. When the road split to 4 lane I stepped on the gas to speed up from 55 to 65 and the vehicle studderd and lost all power. Many warning lights cam on and I think it said stop within .3 miles. We pulled to the side of the road and basically coasted to a stop. It was on hybrid power. We called the nearest Toyota dealership and they suggested restarting the vehicle and see if we could make it to them. The engine did restart still with all the warnings on and we were able to drive it to the dealer being really gentle with the throttle. They pulled codes and it was intake related. They removed the air filter and it was dripping wet. The raised intake ingests water when it's raining and if it's working hard enough it pulls it through the filter into the intake and causes the vehicle to suddenly lose power which could possibly cause a accident. I am also concerned about water pulling dirt with it into the motor and causing damage. I have driven the vehicle in the rain since this happened but not pulling a trailer and really working it and so far it hasn't shut down on me yet but I've pulled the filter and it was wet. I have brought this issue to my dealer but they said they are not aware of a problem. I will attach a video of the wet filter I pulled from the air box after driving in a rain storm and a video of the warning lights that appeared. I don't think the dealership I took it too has any records of it because it was just after closing and they used a handheld scanner. They just dried our filter off and cleared the codes.

Purchased used car from champion motorsports. I was handed a clean carfax report and was told the sunroof had no issues. 8 days later the seal around the sunroof came off and allowed water into the car. I scheduled a repair and brought it to passionauto body. On June 16th they notified me the car was unsafe to drive due to two support brackets being cutout and not replaced. After some research Toyota of calumet city had top coverage in some service notes. Car was also brought back to the shop on December 15th 2025 due to the sunroof not closing. Of course there were no notes on the service ticket.

AIR BAGS
The contact owned a 2025 Toyota 4Runner. The contact stated that while driving at an undisclosed speed, the contact observed a large piece of debris in the roadway. The contact stated that traffic ahead was maneuvering erratically to avoid the debris, causing the contact to lose control of the vehicle. As a result, the vehicle left the roadway, struck several trees, and then collided with a brick wall. The contact stated that the air bags failed to deploy during the crash. A police report was filed. The contact sustained injuries to the leg, arm, and back and was transported to a local emergency room for medical treatment. The contact stated that surgery might be required due to the nerve injuries sustained in the crash. The vehicle was towed by the insurance company and was deemed a total loss. The contact believed that the failure may have been related to an improper repair for a battery replacement previously performed by the dealer. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 9,500.

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.

VISIBILITY/WIPER
While driving my 2025 Toyota 4Runner in rainy conditions, the vehicle’s stamped hood channels act as a reservoir, trapping and pooling large volumes of standing water. Upon braking or decelerating—even at low, around-town speeds—the pooled water surges forward off the front nose of the hood onto the windshield. The vehicle's forward aerodynamics catch this massive sheet of water and instantly launch it backward across the entire windshield, causing total and sudden loss of forward visibility. This creates an unpredictable, immediate crash hazard that catches the driver completely off guard, as the windshield wipers cannot clear the sudden volume of water fast enough to maintain a safe view of the road. This occurs around town driving (25mph to 45mph) and highway speeds (60mph - 70mph). I understand you can turn the wipers on high, but it catches you off guard when it happens.

SERVICE BRAKES
New, strange noise started in Dec'25 (41K miles; 2yrs 9 months). No warning lights. Diagnosed as failed brake accumulator (first at an independent shop, later at the dealer). Apparently the accumulator is part of the full master cylinder assembly which must be replaced. Toyota has quoted $3,200 to complete this repair and is telling me it must be out of pocket.
