How to Escalate a General Motors Complaint
Start with the dealership or support route closest to the issue. For a repair, warranty, parts, service, or recall complaint, contact the GM dealer involved and ask for the service manager. For a sales, delivery, order, or purchase issue, contact the sales manager or general manager. For financing, lease, title, payoff, or payment issues, contact GM Financial. For connected services, Wi-Fi, vehicle app, or subscription issues, contact OnStar or the appropriate GM owner-support route.
If the dealership or first support route does not resolve the complaint, contact the correct brand customer assistance center for Chevrolet, Buick, GMC, or Cadillac. Keep your VIN, repair orders, dealer name, mileage, photos, support history, and requested resolution ready. Ask for a case number and keep written records of every response.
If the matter remains unresolved after using normal dealer and customer-service routes, you may contact General Motors corporate office. Written corporate correspondence may be sent to General Motors Company at its current headquarters or to the official GM correspondence P.O. Box. Corporate correspondence is best used for unresolved or higher-level issues after dealer, brand, GM Financial, OnStar, and owner-support routes have been attempted.

GM Dealer, Warranty, and Repair Complaints
GM dealer complaints may involve service appointments, repair delays, warranty decisions, parts availability, repeat repairs, diagnostic fees, loaner vehicles, communication with the service department, or disagreement over whether a concern is covered by warranty. Start with the dealer’s service advisor and service manager, then escalate to the correct GM brand customer assistance center if the matter is not resolved.
Before escalating, collect repair orders, diagnostic reports, warranty statements, photos, service advisor emails, and dates the vehicle was in the shop. If the issue involves a repeated repair, document each visit separately and keep copies showing the mileage, complaint, repair attempt, and final invoice.
GM Recalls, Safety Campaigns, and Vehicle Concern Complaints
Recall and safety complaints may involve recall notices, parts delays, dealer scheduling problems, campaign completion, warning lights, airbag notices, battery concerns, engine concerns, transmission concerns, braking concerns, software updates, or safety-related vehicle behavior. Use GM’s official recall lookup, the brand support page, or the National Highway Traffic Safety Administration recall lookup for current recall information.
If you believe a vehicle has a safety defect that is not being handled properly, keep documentation and consider reviewing official safety-reporting options such as the National Highway Traffic Safety Administration. For public comments, describe the issue generally and avoid posting your VIN, license plate, insurance records, or personal identifying details.
GM Financial, Loan, Lease, Title, and Payment Complaints
GM Financial complaints may involve payments, payoff quotes, lease-end inspections, excess wear charges, mileage charges, title issues, billing statements, autopay, account access, late fees, repossession concerns, or vehicle purchase options. Start with GM Financial at 1-800-284-2271 and keep payment confirmations, lease documents, inspection records, payoff letters, title records, and account messages.
If your complaint involves a dealer sale, trade-in, lease return, payoff, registration, or title issue, the dealer and GM Financial may both be involved. Ask for written confirmation of the payoff, account status, title status, mileage charges, inspection findings, or lease-end obligations before escalating.
OnStar, My GM Account, App, and Connected Services Complaints
OnStar and connected-services complaints may involve account access, subscriptions, cancellation, remote vehicle features, Wi-Fi, vehicle location services, diagnostics, safety services, emergency services, data privacy, the vehicle mobile app, digital features, or communication between the vehicle and app. Start with OnStar at 1-888-466-7827 or the support route tied to your GM account.
Because connected services can vary by vehicle brand, model year, equipment, trial status, subscription plan, software version, and account status, support may need detailed vehicle and account information. Do not post your VIN, app account email, password, location details, or one-time passcode in public comments.
