NHTSA Complaint #11524050 — 2019 GMC ACADIA

2019 Acadia originally displayed a shift to park message at 12K miles and vehicle was still under warrantee. New shifter harness was installed and a wire harness jumper added. GM covered the cost of repairs. At the time I was told hopefully the repair fixes it but a chance it won't and will need to bring it back in. Two years later at 36K miles it occurred again but was out of bumper to bumper warrantee so GM would not cover and dealer would not give any discount. Both the dealer and the GM claim rep I talked to were not able to adequately explain why this is not considered in the powertrain warranty which is still valid. GM did reimburse 50% of the cost of repair but I am still out ~$380. This issue seems well documented across numerous models / years of GM products.
