2016 Chevrolet Silverado 2500 Electrical Problems

Had new Western Wideout snowplow (recommended by Western) installed by Western dealership on a 2016 Chevrolet Silverado 2500hd with the factory snow plow prep package (RPO VYU). Vehicles instrument cluster, HVAC, Radio and other electrical systems cut out while operating snowplow. GM is well aware of this issue per GM Service Bulleting NO.: PIT5387C (Feb 2016) through PIT5387P (10/17/2024), as well as GM Upfitter Integration UI Bulletin #124K (11/7/2019). All list this specific vehicle. This issue effects snowplows by all manufactures and is not confined to Western. Per the above bulletins published by GM, GM is to supply and install a wiring harness under a unique one time warranty procedure that does not expire with the vehicles base warranty. GM dealerships as well as GM's consumer assistance hotline state that GM part number 84043394 (fitting 2014-2019 vehicles) referenced to in PIT5387C and other bulletins has been discontinued. UP Bulletin 124k refers to and instructs to install GM part number 84288774 VYU Snow Plow Jumper harness per the latest version of GM service Bulletin PIT5387. With a note stating "this jumper harness and installation will be provided (one time) without charge". GM dealerships and GM customer assistance (parts) state that PN 84288774 does not appear in their parts system as a valid GM part. The official GM parts store [XXX] lists this part but shows that it does not fit this vehicle. Therefore neither GM nor Western is able to provide any actionable solution to this known and documented issue. GM manufactured, sold, promoted, advertised and continues to state that snowplows can be installed on these vehicles with (or without) GM's factory snow plow prep option. Additionally GM continues to issue and publish Bulletins instructing GM dealerships how to fix this issue despite being fully aware of this impossibility. GM has also made it impossible for GM to honor GM's own warranty that is still in effect for A KNOWN SAFTY ISSUE. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATI

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.

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.

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!
