I just bought a 2019 Sierra Denali 1500 6.2L. It comes standard with the HUD display that since day one is malfunctioning. When I turn the car on it seems to be all working and all the information is projected as it should. The problem happens when the car starts moving. The speed just disappears. It doesn’t matter if It is forward or reverse. Everything else stays there but the speed. I already brought it to the dealer and they have no clue. They updated the software hoping it would solve the problem but it didn’t. I also called GM and I am waiting for them to call me back with a solution. My car has now 800 miles and the dealer said there is nothing they can do. So I paid 60k for a car with defective equipment and they said that’s my problem now. Any suggestions? Did it happened to anyone else?
