2023 CHEVROLET COLORADO Complaints

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.

The first day of driving a brand new, 2023 Chevrolet Colorado, my turn signal shifter started to fail. When I move my turn signal left down (left turn position) then back to the neutral position, the left turn signal stays active. The turn signal shifters also binds and gets stuck in the neutral position and will not allow me to move the turn signal shifter upwards (right turn position). To fix this, I have to move the turn signal shifter back to the left turn position to get the shifter unstuck then it will allow me to move the turn signal shifter back upwards to the right turn position. I have been on the highway and unable to use my right turn signal to change lanes which is extremely dangerous. I am worried that it will cause an accident or that I will get a ticket for not using my turn signal. I have a video of the issue occuring, but the video is 25 MB. The issue occurs every time I drive but not 100% of the time when I try to use the right turn signal. When the issue does occur, it's always due to shifting the turn signal shifter into the left turn position and becomes mechanically stuck in the neutral position.

Driver backed the truck out of a parking spot and the brakes did not engage. The service engine soon light then came on and said it was an anti-lock brake failure. Their have been two guesses so far as to what caused this. A faulty master cylinder or an issue with the engine control module relaying info to the brake control module and/or transmission control module.
