The infotainment center seems to malfunction and push buttons on it's own or not respond to input, which seems related to a more serious problem I experienced where the gauge cluster was not reading anything out when I was driving, including not knowing what speed I was at or what gear I was in. I had to turn the vehicle off several times and restart it several times before the issue resolved.

My trailer brake warning bell keeps coming on all the time saying service trailer brake , then says connected. I have pulled the fuse as to not here this bell all the time. I just changed the module and it still does it. It is very annoying and not haveing brakes for the trailer really sucks. When will this be fixed.

I’m getting a service trailer brake system notification( it’s has been showing up for awhile now). I’ve seen several times where this has come up with individuals that own the same year and makes. Why hasn’t Chevrolet address this situation yet. Any solution would be helpful.

Failure of the HMI caused a flickering screen during driving operations with warnings and cautions constantly flashing making it very difficult to concentrate on the road conditions and traffic. Parking the vehicle using the back up camera was also affected making it impossible to see approaching objects from the rear.

WHILE DRIVING ON A CITY STREET I SMELLED SOMETHING BURNING I HEARD A SIZZLING SOUND AND LOOKED IN THE BACK AND SMOKE WAS ROLLING FROM BEHIND MY PASSENGER BACK SEAT. I REALIZED IT WAS COMING FROM THE WIRE CONNECTION FOR REAR DEFROSTER. THE SMOKE STOPPED AFTER ABOUT 10 SECONDS SO I CONTINUED DOWN THE ROAD AND AFTER ABOUT 30 SECONDS A LOAD BOOM OCCURRED AND THE PASSENGER REAR SECTION OF MY ELECTRIC SLIDING WINDOW WITH DEFROST EXPLODED. I TOOK IT TO THE DEALER AND THEY SAID IT WASN'T COVERED BY WARRANTY OR RECALL. THIS IS BEING RECALLED IN CANADA ON THE SAME TRUCKS BUT NOT U.S. TRUCKS.

THIS IS NOT A SAFETY ISSUE BUT I AM EXPERIENCING A PROBLEM WITH MY AUDIO SYSTEM IN THE 2016 SILVERADO 2500 HIGH COUNTRY TRUCK. THE AUDIO SEEMS TO GO IN AND OUT OF STEREO SOUND AND ALSO SSEMS TO BE CHANGING ITS EQUALIZATION PERIODICALLY. THERE DOESN'T SEEM TO BE AND RHYME OR REASON WHEN THIS HAPPENS; DOESN'T HAPPEN WHEN I HIT A BUMP, OR STOP SUDDENLY, OR ANYTHING LIKE THAT. THE SOUND SYSTEM WILL JUST RANDOMLY CUT IN AND OUT IN THE MANNER DESCRIBED ABOVE. IT IS MILDLY ANNOYING AND IF ANYONE KNOWS WHAT THIS COULD BE I'D APPRECIATE THE HEAD'S UP. IT'S BEEN TO THE DEALER FOR MAINTENANCE AND I ASKED THEM TO TAKE A LOOK AT IT WHICH OR COURSE, THEY DIDN'T FIND ANYTHING. I KNOW I'M WHINING BUT WHEN YOU SPEND $51K FOR A VEHICLE YOU WANT EVERYTHING TO WORK ON IT, RIGHT!
