NHTSA Complaint #11706942 — 2016 CHEVROLET SILVERADO 2500

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
