My 2023 Colorado's speedometer and infotainment digital display, which includes my ability to turn on and off my headlights, are both broken and not working. This makes it impossible to know my speed, how much gas I have, or turn on my lights at night. This was my core concern when getting the new 23 Chevy - too much reliance on displays - and it has come true. I have seen on Reddit and other boards that TONs of other users are facing similar issues, and it seems to be because of a botched software update. Please investigate.

Vehicle was purchased brand new with 3 miles on it. The vehicle informant system was malfunctioning not allowing phone calls to be made or connection with OnStar. No audio was being produced through the speakers and the headlights were not responding when pressing the headlight buttons on the informant system. Battery was disconnected for 10 minutes and informant system was back online with no issues after that. Vehicle now has 554 miles on it with no problems. The dealership stated this has occurred with a few other 2023 Colorado's.

I've had two problems both dealing with the truck's infotainment system. The first problem was that the software "glitched" and the screen became unusable (see attached pictures). The headlight controls are exclusively accessed through this screen and I had to remove the negative battery cable for 10+ minutes to recover this screen and access my headlight controls. The second problem was an over the air updated pushed to my truck over the weekend of 7/21/2023 to 7/24/2023. The update did not install and caused my truck's battery to drain while not in use. I was forced to jump start the vehicle the morning of 7/24/2023. The truck had 7500 miles at the time of battery failure.
