Lexus GX550

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…

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…

The GX 550 has many people online complaining about the windshields cracking from the bottom for no reason. The crack is getting worse and close to line of sight. This is happening without something striking it.

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

The issue started with the engine stalling while I’m driving, and one day the car failed to start. I towed it to the dealership who said there is nothing wrong with the fuel pump and advised me to replace the battery. I replaced the battery and drove it for a couple more months, while the engine continued to stall from time to time and eventually failed to start again yesterday. It’s very apparent that the issue is with the fuel pump, and there is a recall for the fuel pump for the 2015, 2016,…

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.
