Push start button malfunctioned. The vehicle would not turn off last night and took about 30 minutes to get vehicle to turn off. Next day, had the same issue where vehicle would not start and left me stranded. After calling for a tow truck, I was able to start the vehicle. When researching the problem online, I saw several other complaints of the same issue where the buttons malfunctioned and could either not start their vehicle or turn the vehicle off.

On three separate instances (two after paying $3,000 to "fix" it) my 2021 Trailboss is flashing warnings of: Park Assist Off, Steering Assist is Reduced Drive with Care, Service 4WD, Service Trailor Brake System...all while driving down the rode and losing all gauges/flatlining and no fuel warning engaging (had a 1/2 tank). The Chevrolet Dealer claims it's not producing a code (Thankfully I recorded the evidence)...Truck has just over 40k miles and has been driven with care. **Pictures are all while driving down the road** Serious electrical and SAFETY ISSUE and it needs to be RECALLED and addressed!

I bought this vehicle brand new off the lot in 2021. Truck hasn’t had any problems until this year. Every few weeks it will randomly just not want to start, I’ll usually check the battery and the battery will be completely drained. I can’t figure out what is causing the battery to drain like this, but something needs to be done as I have literally been stranded places due to my truck just deciding not to start randomly. Today i’m having this exact problem, my trucked was parked overnight in my garage and I went to go to work this morning and once again the truck won’t start and battery is drained. All my doors are shut and no interior lights are left on.

The ESC, parking light, traction control, and engine light came on while driving home. The engine started to shake. There was an issue with braking and steering the vehicle that made it difficult to control. A message on the dash said Service ESC. A report was sent via OnStar Notifications that said An issue with the emissions system is detected. After trying to restart the vehicle a few times, the lights will not go away. The truck is driving rough.

INFOTAINMENT SYSTEM DOES NOT WORK ALL THE TIME. XM RADIO HAS NO SOUND AT ALL, OR AS I AM DRIVING DOWN THE ROAD THE XM RADIO VULUME ON ITS OWN GOES SO LOW YOU CAN NOT HEAR IT AND THEN YOU CAN NOT TURN IT UP OR DOWN WITH THE VOLUME CONTROL ON THE DASH OR THE ONE ON THE STEERING WHEEL. TO CORRECT THIS ISSUE ONE HAS TO TAKE THIER EYES OFF THE ROAD AND USE THIER PHONE IF IT IS PAIRED WITH THE SYSTEM OR TURN THE RADIO TO FM OR AM. AFTER DOING THIS THE VOLUME CONTROL WORKS ON XM. THIS HAS HAPPENED SINCE I GOT THIS VEHILCE NOV 30,2020 UNTIL NOW ON AND OFF.
