Manufacturer dispute resolution and owner grievance arbitration on the 2023 GMC are regulated by General Motors customer assistance centers, zone manager reviews, and independent automotive mediation boards.
How to Fix It:
-
Contact Customer Support: Call the toll-free GMC customer assistance line to report your vehicle issue and open a formal case file.
-
Request Case Review: Ask your assigned representative to escalate the matter to a regional service manager for a secondary evaluation.
-
Explore Mediation: Utilize third-party dispute resolution services like the BBB Auto Line if factory negotiations do not resolve your concern satisfactorily.
