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.

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.
