Yesterday, when driving around for errands, the main screen(the one with the speedometer, etc.) on the GLS went black. Its about 3 months old and has 6300 miles. I tried turning off the car and restarting - no luck.

I was able to get in touch with a local dealer, there are only two here in Northern NM, and the service advisor suggested after turning off the car, then locking it and waiting for 5 to 10 minutes. Bingo that worked. He said it was likely a software issue and the car needed to go to “sleep”.

I don’t know about that but it did work.

Cars are more computers than not these days so doing a cold reboot every now and then probably is the answer!

I had the same issue yesterday. Main screen went black after picking up groceries. Drove 5 minutes to my next stop. Locked the car. Main screen seemed to reset itself and was fine afterwards.

Sorry you had the same issue - glad I am not the only one - happy that it reset. Mine has worked fine since I reset it.

So they tell us we don't need buttons....

I'll leave the brand if I have to deal w/a blank screen and can only use voice recognition. Did voice even work when the screen was blank?!!!

I didn't try since only drove a few blocks to my next stop. Heads up display was still working as was Waze on the center screen.

We had the same experience this week. Just turning it off and back on was not enough to get it back but it did come back after letting the car sit for a while.

That is what I tried and it didn't - had to have the car locked for more than 10 minutes and it had reset.

How did you end up resolving this issue?

A couple of years ago, my 2022 GLS 450 wouldn't start. Got in, pushed the start button and there was nothing, just plain nothing. Call my dealer and he said the same thing - take all the keys, lock the car, and go away for 30 minutes. That's what I did, and when I came back the car started up just fine and I haven't had a problem since. These computer cars are weird, but I guess we all have to learn to live with them now.

Something similar happened to me as well but I didn't know this solution. I just parked the car and was sitting in it for maybe 5min, engine was turned off but radio was still playing. I then decided to re-park thinking that I might be to close to the stop sign (curbs were covered in snow so I couldn't see any red curbs). I tried to start it and it would turn over the motor but when I tried to change gears the engine would kill. Tried several times and then I said to hell with it, left it and ate lunch. It was a stressful lunch not knowing my car would start and thinking I might have to get it towed out of the mountain town I was in. Anyway, it started just fine after lunch and haven't had an issue since. No codes were thrown and SA said the same as you. Lock it up and let is sleep and try again. I've never had this issue a second time.

I received a similar black screen last month.
I had started loading maps from my thumb drive, then It went black.
I looked at my Mercedes me app and it said another download was in progress.
I waited. Next time I got in the car the screen was alive and the map download had resumed.

So in the above mentioned cases, I wonder if there was a simultaneous download that I was competing for screen time.
