Instrument Cluster/panel Problems of Chevrolet Silverado 2500

Had new western wideout snowplow (recommended by western) installed by western dealership on a 2016 Chevrolet Silverado 2500hd with snow plow prep package. Vehicle's instrument cluster, hvas, radio and other electrical systems cut out while operating snowplow. Gm is well aware of this issue which has been discussed and documented per gm service bulletin no. : pit5387c (Feb 2016)- pit5387p (10/17/2024), as well as gm upfitter integration ui bulletin #124k (11/7/2019). Western states the fix for this issue is for gm to supply and install a wiring harness (per the above gm bulletins) gm dealerships as well as gm consumer assistance hotline state that gm part number 84043394 (fitting 2014-2019 vehicles) referenced to in pit5387 and other bulletins has been discontinued. Therefore gm can not nor will ever be able to obtain or install this wiring harness in the future. Gm upfitter integration bulletin #124k instructs to install a different part number 84288774 vyu snow low jumper harness per the latest version of gm service bulletin pit5387. "note: that this jumper harness and installation will be provided (one time) without charge. " gm dealerships state pn 84288774 does not appear in their system as a valid gm part. Parts. The official gm parts store at [xxx] , list this part but shows it does not fit this vehicle. Therefore neither gm nor western is able to provide any actionable solution to this known safety issue. Western (and other manufactures) still manufacturing, recommending and installing snowplows for this specific vehicle. Gm, manufactured, sold, promoted, advertises and continues to recommend snowplows to be installed on these vehicles (with the gm factory snow plow prep option), and continues to issue bulletins instructing gm dealerships how to fix this issue despite being fully aware gm cannot supply these parts. Therefor gm has made it impossible for gm to honor their own warranty that still currently in effect, for a known saftey issue. Information redacted pursuant to the freedom of information act.
