STEERING

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.

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.

UNKNOWN OR OTHER

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

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.

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.

POWER TRAIN

The contact owns a 2025 Toyota 4Runner. The vehicle lost motive power while attempting to access the freeway on three occasions. The reduced power mode message was displayed. The vehicle was taken to the local dealer, and initially they were unable to determine the failure. The vehicle was taken to the local dealer again, where it was diagnosed that the sensor needed to be cleaned. The vehicle was repaired, but the failure persisted. The manufacturer was contacted, and a case was open. The failure mileage was approximately 11,000.

I am reporting a suspected manufacturing defect involving the exterior paint on my 6th generation Toyota 4Runner. The paint appears to be abnormally thin and is showing premature wear, including chipping and surface irregularities, under normal driving conditions. This vehicle has not been subjected to any abnormal environmental exposure, misuse, or neglect. The condition developed much earlier than expected for a new vehicle and raises concerns about inadequate paint application or quality control during manufacturing. While this issue is cosmetic in nature, it may lead to long-term structural concerns such as corrosion if the underlying metal becomes exposed. Additionally, this concern appears to be reported by multiple owners of the same generation vehicle, suggesting a potential pattern rather than an isolated case. I am requesting that this issue be documented and reviewed for possible investigation if additional complaints are received.

Driving 70 mph on a cloudy 73° day around 6:30 pm no cars immediately around me on I45. I heard a loud gunshot to the point I ducked in my car. Immediately pulled over walked around the car. My Sunroof exploded upwards. Took to Longo Toyota on Monday at 7am. Upon arrival they thought it would be covered under warranty. They brought in a specialist to evaluate and they can’t prove it but something must have hit it and they are denying warranty. The glass moved upward and was shattered but intact upon initial inspection. Upon online review this is a known problem w Toyota but one that needs to be addressed in a bigger scale as this could have caused an accident just from the sound alone or if the sunroof cover had been open glass raining down on passengers and driver.

UNKNOWN OR OTHER

Vehicle: 2025 Toyota 4Runner Summary of Issue: The rear tailgate cannot be opened if the rear window is even slightly lowered. This appears to be an intentional design feature; however, it creates a real-world safety concern. Description of Safety Concern: In normal daily use, I needed to quickly access the rear cargo area (to retrieve my child’s belongings) while parked with the vehicle turned off. The rear window was partially lowered, which prevented the tailgate from opening entirely. This resulted in a delay while I attempted to determine why the tailgate would not open and then had to return to the driver’s seat to raise the rear window before accessing the cargo area. During this time, my child was left standing in a parking lot longer than necessary. While the vehicle was stationary, the inability to quickly access the rear compartment created an avoidable safety exposure. Why This Is a Concern: The system does not account for vehicle state (e.g., parked, engine off, zero speed). A more appropriate design would allow the tailgate to open when the vehicle is stationary or automatically raise the rear window when the tailgate is activated. Instead, the current behavior enforces a strict lockout regardless of context, which can delay access in situations where timely access is important for safety. Requested Action: I request that this behavior be reviewed for potential safety implications and that consideration be given to a software update or design change that allows tailgate operation when the vehicle is stationary, or provides an automatic window-close function when opening the tailgate. Additional Notes: This behavior may be present across multiple model years and could affect a large number of vehicles.

SERVICE BRAKES

Brakes squeak/squeal very loudly and often, no matter if it’s cold, rainy, hot or humid. It was only squeaking/squealing when applying the brakes while backing up but now starting to squeak/squeal when applying the brakes while moving forward. Seems to be getting worse. Spoke to the dealer and they say there’s nothing they can do until Toyota comes up with a fix.

STEERING

While going around turns (left or right) over 30mph the vehicle has knocking that can be felt coming through the steering wheel. This is not the driver assist feedback. If the turn are longer (like highway on ramp) you can hear a slight clunk associated with the knocking that is felt.

SERVICE BRAKES

The brake system emits a high-pitched noise, which seems to be worn down to the discs when used in drive mode and reverse mode. At any moment, they could stop working or cause an accident. The problem was reported to the dealership on October 28, 2025, when the vehicle had only 3,171 miles. The vehicle is still under warranty. It has been inspected by the dealership. To date, it has not been repaired. The dealership reports that this problem has occurred in most of these vehicles. There were no warning lights or warning messages. The situation first occurred when the vehicle had approximately 3,100 miles and was reported to the dealership at 3,171 miles.
