2024 Lexus GX

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

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.

My car was stolen via a can-bus attack - it was locked while it happened. The alarm was going off and they still stole the car. It took less than 3 minutes.

I have a 2024 Lexus GX 550 Overtrail with about 4,500 miles on it bought in December 2024. I went to start it this afternoon and I got a message saying "Low Steering Power". All the electrical things on the car seemed to be working: lights, dash lit up, courtesy lights, all the screens, etc. It just wouldn't turn over. I shut the car off and gave it a minute or two then tried again. Nothing. At the same time, the car started to make a low, continuous humming sound and made a couple of clicking noises about every 10 seconds. It sounded like the hum of a refrigerator and seemed to be coming from the front half of the car. The car was totally turned off at this time. I then called Lexus Roadside assistance (the car was in my garage; hadn't used it in about 48 or so hours). When the flatbed driver arrived he tried to start it a few times. When he did this the car began to smoke from the fuse box. A significant amount of acrid smoke and severe odor of burning plastic developed. The flatbed driver and I immediately pushed the car out of the garage for fear of a fire starting and engulfing more than just the car. The fuse box and some of the fuses in it were melting. No flames developed but I'm quite certain that was a possibility. This just happened today. The dealer said they are going to begin investigating the issue. I'm very concerned that if others have this problem it could develop into something more serious. From what I've discovered from an internet search is that the combination of the "Low Steering Power" error message and the smoking fuse box condition "indicates a likely electrical short or significant component failure that could lead to a fire." I've uploaded a pic of the partially melted fuse box. I have no paperwork from the dealer service department as yet.

I was just getting off from work starting the engine, the driving meters screen and the head up display were completely off black, I thought that it will turn on after driving but it didn’t. I was driving more than 5 minutes on the free way and both screens were still dark. This is not the first time that this happened. The last time when this was happened, I brought my vehicle to the dealership where I purchased it, but then everything went back normal when I got to the dealership parking lot. They never performed any diagnostic or checking anything. Also the navigation/multi media scene flashing quite a bit. This car electrical system didn’t function properly and correctly when driving and could cause serious accidents or deaths, depending on who was driving. I really don’t know what more failure after this. In the past, Lexus had history of vehicle brake failures and couldn’t stop that claimed someone lives. This issues should be addressed before something else happens. ( I also have video available to support this concern)

Some 2022 – 2026 model year LX 600, 2024 – 2026 model year GX 550, and 2025 – 2026 model year LX 700h vehicles may exhibit a condition where the front brakes produce a squealing noise when driving forward or in reverse

Some 2024 – 2026 model year GX 550 vehicles may exhibit a vibration at idle when in drive. The Engine Control Module (ECM) logic has been modified, in addition to improved exhaust hangers, to help improve this condition.

Some 2024 – 2025 model year GX 550 vehicles may exhibit a harsh downshift (2 – 1) when slowing to a stop. The Electronic Controlled Transmission (ECT) ECU logic has been modified to address this condition.
