The Heads up display seems to come up every other time the car is started. If it does not turn on, I can restart the car and it is fine. If I leave the car for a while and restart, it will not come on if it was on when I shut off engine.
Does anyone else have this problem?

2021 Cadillac CT4 - my heads up display stopped working as well with only 2000 miles on the car.
Dealer has no idea why except to bring it in for service.

Mine has worked consistently.

You have to be looking at the correct angle. When it doesn't work, move around or try to
adjust it, to make sure it's not working at all.

Confident it is not working at all - can't find a fuse nuber that is applicable to it and surprisingly memory seats stopped working at the same time ???? I did check the fuse for that one though which is in the trunk.
