SERVICE BRAKES
There is a significant squeal when braking at low speed in both forward and reverse. I am unsure whether this is a safety issue or not, but there is evidence online that other owners are experiencing the same issue.

STRUCTURE:BODY, UNKNOWN OR OTHER
Sunroof tempered glass spontaneous explosion. Loud explosion startled me and my wife, good thing the sliding roof cover was closed otherwise small pieces of sharp glasses will hit us on our head, face and shoulders. Lexus of Oakland denied any product defect and blaming a foreign "magnetic" object hit the sunroof. I was only driving 20 mph in a residential neighborhood and no cars in front of me when the sunroof exploded. No warning lamp or symptoms prior to the incident. My wife and I were scared!

SEAT BELTS
Subject: Urgent Safety Concern – Driver Seatbelt Malfunction I am writing to formally report a serious safety concern regarding the driver-side seatbelt in my vehicle. The seatbelt does not retract properly and frequently becomes caught in the door. In addition, the retractor fails to pull the seatbelt back completely, leaving slack in the belt. More concerning, there have been multiple instances where the seatbelt did not properly engage or lock when braking was applied, even though it was securely fastened. I brought the vehicle to the dealership for inspection, but I was advised that this condition is “normal.” I strongly disagree with this assessment. A seatbelt that does not retract correctly or fails to lock during braking poses a significant safety risk and does not meet expected safety standards. This issue raises serious concerns about the reliability of the restraint system in the event of an accident. I am requesting a thorough inspection of the driver-side seatbelt system, including the retractor mechanism, and that any defective components be repaired or replaced immediately. Please document this concern formally and provide written confirmation of your findings and recommended corrective actions. I am very concerned for my safety and expect this issue to be handled with the urgency it deserves.

ENGINE
My engine failed as I was driving down the highway at high speed. I was thankfully able to move over lanes and park safely on side of the rode before it came to a complete stop. It never turned back on. Lexus had to send a tow truck to pick it up and has been @ Dealership in Lubbock tx since 3/9/26

UNKNOWN OR OTHER
The driver-side front door window developed a crack suddenly while the vehicle was in normal use. There was no known impact, and no object was seen or heard striking the glass. The crack originated near the edge of the window close to the side mirror and spread across the glass. There were no warning messages, alerts, or prior symptoms before the failure. The failure appeared spontaneous. This condition poses a safety concern because the integrity of the side window is compromised. The crack continued to spread, which could reduce occupant protection in the event of a side impact and may lead to sudden shattering. It also has the potential to affect driver visibility. The issue was not inspected by the dealership prior to repair. The dealership advised that they could not perform the repair in-house and directed the repair to a third-party glass facility, where the window was replaced. No definitive impact point was identified prior to replacement. Based on the fracture pattern and lack of impact evidence, the failure appears consistent with a stress-related crack rather than road debris damage. Additionally, there are multiple reports from other owners describing similar cracks occurring in the same location on this vehicle model, suggesting a possible defect trend. The original failed component is no longer available for inspection, as it was replaced during repair.

UNKNOWN OR OTHER
My less than a year old Lexus GX550 was sitting in the driveway and the sunroof exploded. The car was not moving and it exploded outwards into a ton of pieces. The dealership claims that it is not a warrantable part. No foreign object hit the sunroof, even then it shouldn't shatter, only crack. It is my assumption that defective glass from the factory was installed into my vehicle and caused the sunroof to shatter for no apparent reason.

SEATS
The driver’s seat is making cracking, clicking, popping, and creaking noises from the lower seat frame, seat rail, or mounting area where the seat attaches to the vehicle body. The noise is most noticeable during braking, acceleration, turning, driving over uneven roads, and when shifting body weight in the seat. It feels as though the seat has movement or play, as if the seat rails, frame, or mounting bolts may not be fully secure. This is a safety concern because the seat is part of the occupant restraint system and is critical for proper seat belt positioning and airbag protection. If the seat frame, rails, or mounting hardware are loose, damaged, worn, or improperly secured, the seat could shift during a sudden stop or collision. In an accident, movement of the seat could reduce seat belt effectiveness, alter occupant positioning relative to airbags, increase the risk of impact with the steering wheel, dashboard, door, or center console, and increase the likelihood of head, neck, chest, back, pelvic, or leg injuries. Unexpected seat movement could also affect driver control immediately before or during a crash. This should not be treated as a simple interior rattle. The seat mounting bolts, rails, locking mechanisms, adjusters, frame components, and floor mounting points should be fully inspected for looseness, improper torque, wear, cracking, or structural failure. I have also found numerous similar owner complaints online from Lexus GX owners reporting clicking, cracking, rocking, or shifting driver seats that feel loose or unstable. Based on forum discussions and owner reports, there appear to be dozens of similar complaints, suggesting this may not be an isolated issue.

SERVICE BRAKES, POWER TRAIN, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
On April 17, 2025, while driving a 2024 Lexus GX 550 Luxury Plus with a minor passenger in the vehicle, the vehicle locked up without warning as I was exiting the highway. The sudden lockup caused skid marks on the tires. The failure occurred at low speed only because I had just turned off the highway — had it occurred moments earlier at highway speed, the consequences could have been fatal. The failed component appears to be the drivetrain or braking/locking system. The vehicle is currently in the possession of the Lexus dealership and is available for inspection. A Lexus field inspector has been scheduled for early May 2025. Safety was put at serious risk. A child was in the vehicle. The lockup was sudden and without warning, with no ability to anticipate or respond. This incident was preceded by two prior issues with the same vehicle: (1) approximately one month prior, a transmission concern was reported to the dealer, who attributed it to abnormal driving habits and took no corrective action; (2) on April 7, 2025, brake rotors were replaced under a recall for rotors that squeak when exposed to moisture. The problem has been confirmed by the dealership, which has retained the vehicle since April 17, 2025. I am aware of at least 8 to 10 other reported incidents involving the same model vehicle with the same lockup failure. No warning lamps or messages appeared prior to the failure.

ENGINE
Vehicle experiences a persistent and abrupt harsh downshift (jerk/thud) specifically during 2nd-to-1st gear transitions when rolling to a stop. This issue persists despite the dealership performing the recommended Transmission Control Module (TCM) software update at 5,000 miles. The smooth shifting returned briefly for approximately 500 miles post-update before the abruptness returned. Additionally, there is a noticeable vibration/harmonic change in the engine as the oil reaches approximately 3,000 miles of use. Concerned that this transmission behavior is a secondary symptom of internal engine drag or main bearing stress, as documented in similar V35A-FTS engine failures. This abrupt downshifting creates a safety concern regarding predictable vehicle deceleration in stop-and-go traffic. Vehicle is currently at 6,700 miles.

POWER TRAIN, VEHICLE SPEED CONTROL, SEATS
I am reporting two safety-related problems in my 2022 Lexus GX 460, both present since shortly after purchase and the vehicle is available for inspection upon request. 1. Power Train / Speed Control (delayed acceleration / no throttle response): When I transition from the brake pedal to the accelerator pedal quickly (normal driving), the vehicle intermittently displays a warning message indicating the accelerator is being pressed while the brake is also pressed (or similar wording). When this happens, the vehicle does not respond to the accelerator for several seconds even if I press the accelerator to the floor. This has put my safety and the safety of others at risk because the vehicle fails to accelerate when needed (e.g., when merging, turning, or avoiding traffic), creating multiple dangerous near-miss situations. The warning message appears at the time of the event; I did not notice a warning lamp or message consistently prior to the event. This issue has not yet been reproduced or confirmed by a dealer or independent service center. A dealer service visit is scheduled for next week. The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives for this problem. 2. Seats (driver seat causes leg numbness/spasms impairing pedal control): The driver seat bottom is unusually firm, and after approximately 30 minutes of driving my legs become numb from the lower thighs down to my feet and I experience spasms to the point that I cannot safely operate the brake and accelerator pedals. This is a safety risk because it can prevent proper pedal control while driving. This condition has been consistent since shortly after purchase. It has not yet been confirmed by a dealer or independent service center, and the vehicle/seat has not yet been inspected by the manufacturer, police, or insurance representatives for this issue.

SERVICE BRAKES
Notice brakes would not hold vehicle and begin to drift into intersection. Depress brake pedal more and it would stop then start to drift again, then placed into neutral as the brake pedal was almost to the floor. So as you were at a red light the brake pedal never moved but wasn't applying constant pressure to keep vehicle stationary then I'd have to apply more brake pedal and repeat. Ma aged to get to work safely and had it towed to Rohrick Lexus and they kept it for two day having a mech take it home. They could not duplicate!

SERVICE BRAKES
While driving my 2022 Lexus GX460, I experienced a sudden and unexpected loss of braking capability while stopped. After bringing the vehicle to a complete stop, the brake pedal pressure gradually decreased while my foot remained firmly on the brake. As pressure lessened, I applied additional force, but the brake pedal continued to travel downward until it reached the floor. At that point, the vehicle began to move forward at idle despite the brake pedal being fully depressed. I rolled towards the intersection (at a stop light). I took my foot off the brake and applied again. It stopped, and then this repeated. I then put the car in park while I waited for the light to turn green. My destination was only 1km away. When I got there, I turned off the car, and have since been unable to replicate the issue. I took it to a dealership (Lexus on the Park) and they charged me for an investigation and told me the car is good to drive. I need Toyota/Lexus to be informed. Note that I am in Canada but a friend advised for me to submit here. I posted my issue on a Lexus forum and a person named Patrick said he had the same issue in September and was told by the dealership everything is fine. I've asked him to submit to NHTSA as well. His VIN is [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
