Hi guys, new to Trailblazer but not to Chevy. Just purchased a new 2024 Trailblazer RS FWD in Sterling Gray Metallic and have enjoyed it up until today. We were on a short trip (75 mi) to visit my daughter when out of the blue, everything on the DIC and Infotainment screen went black, along with satellite radio and OnStar but did have FM radio but was unable to get anything to work on DIC and touch screen. All DIC and touch screen were blank.

Stayed black for roughly 10 seconds and came back on. 5 or so min later, did the same thing again, over and over for about 6-10 times. I stopped the car and turned off the engine, opened the door and let the vehicle set for about 10 mins and restarted. Everything came back to normal for a few miles until it decided to do it again. Anyone have this same issue happen? I already have an appt. scheduled at the dealer.

Pictures on some of the issues.
If there is any moisture or frost on the windshield or grille, that warning will pop up. Also, your remote battery may be going dead and the car can't detect it. I've found that sometimes resetting a BCM, or the ECM by disconnecting the battery for a few minutes, can cure a lot of these little electronic bugs.

Mine(24 TB Activ) is in the shop until after the 1st year. The service manager told me he was going to have to get with GM to troubleshoot.
I took mine in for the 1st time at the end of October. They couldn't recreate the issue so it came home with me. I then kept a log of dates & occurrences. I emailed the service manager with the log of events. He had a loaner for me the next day.
I bought it in July & had the 1st hiccup at a stoplight a few weeks after purchase. The sporadic "hiccups" continued & started happening more frequently. It got to a point that I didn't know if I could even get back into my TB because the entire system would die so it wouldn't recognize the fob or app to enter the vehicle.

I came looking for information about my 2023 TBRS that the radio died on this weekend. 35k miles almost exactly when it happened. Going to the dealer tomorrow. As for the 2024s and newer. This is a common issue across the board on GM trucks for sure. Worst yet there are no replacement parts. For this reason my wife bought a 2022 Duramax Colorado. We could have bought a new 2024 for the same price but she refused to deal with the display issues as many of the controls are now in the display, including the light controls on many of them.

Many issues with these cars are software related anymore these days. My 21 TB has 83k now. PRetty much no issues. Burns some oil (based on a google search that is common with modern Turbo cars) Keeping the oil changed is KEY to keeping this little motor purring along. Let it run a min or so at startup when it has been sitting to let the oil get to the Turbo.

My daughter’s 2024 Trailblazer RS had intermittent electrical problems, where she would press the start button and it would start to turnover and then everything would go dead. Screen, lights, everything. The first time it happened. I jumped the car off and drove it straight to an auto box where they tested the battery. It was fully charged imperfectly good. Over the next four or five months something similar to this happened although sometimes she would just get in push the start button and everything was already dead and it didn’t even try to turn over. The last time it happened the auto start stop feature was engaged, and the car died as the engine was starting to turn over again and nothing would work no flashers no OnStar no ability to lock or unlock the vehicle. When I get the vehicle home, I noticed the ground wire that I’m pointing to in the photo was very loose. I could easily spin it off with one finger. Ground wires should not be loose at all so I’m hoping that is the cause of the intermittent problem.
