Lexus GX550

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…

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.

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…

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…

Car’s brake fluid leaked out of the brake lines into the master cylinder or brake booster resulting in significant loss of brake fluid to the system and a hazardous driving condition.

My vehicle made a stange sound and then stopped in the middle of the roadway causing a safety risk to myself and others. No warning light appeares until thia incident. Many vehicles were forced to switch lanes to avoid a collision with my vehicle. I had to called the local police to assist me in getting my vehicle to a safe location. I had the vehicle towed to the local Lexus Dealership and it was determined that the vehicle had a fuel pump failure. I am aware that the 2013 Lexus GX 460 was…

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…
