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)

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2024 Lexus GX 550 verdict →
