Where to Send a General Motors Complaint

General Motors has a formal complaint process, but the route depends on what you are complaining about. If the issue involves a vehicle defect, safety concern, or warranty dispute, you file through GM's Customer information Center. If you have a complaint about a dealer's conduct or sales practices, you may need to contact the dealer's management first, then escalate to GM if the dealer does not resolve it. If the complaint involves a safety defect that affects multiple vehicles, you can also report it to the National Highway Traffic Safety Administration (NHTSA), which maintains a separate database.

The fastest way to reach GM's complaint department is by phone: 1-800-462-8342. This line connects you to the Customer information Center, which handles warranty claims, vehicle defects, and service disputes. You can also mail a written complaint to General Motors, Customer information Center, 100 Renaissance Center, Detroit, MI 48243. Written complaints sometimes move slower, but they create a paper record that can be useful if you later pursue a warranty claim or lemon law case.

Key Takeaways

  • Call GM's Customer information Center at 1-800-462-8342 to file a complaint about a vehicle defect, warranty issue, or service problem.
  • Dealer complaints should go to the dealer's management first; if unresolved, escalate to GM's regional office or customer service line.
  • Safety defects can also be reported to the National Highway Traffic Safety Administration (NHTSA) at safercar.gov or 1-888-327-4236.
  • Keep records of all service visits, repair attempts, and communications with the dealer and GM, as these documents support lemon law claims in some states.
  • If GM does not resolve your complaint within a reasonable timeframe, you may have options under your state's lemon law or through arbitration programs.

What Information You Need Before You Call

Have your vehicle identification number (VIN) ready. The VIN is a 17-character code stamped on the driver's side door jamb and visible on your registration and insurance documents. GM's system pulls up your vehicle history, warranty status, and any previous service records using the VIN, so having it available speeds up the call.

You will also need the date the problem started, a description of what is happening (noises, warning lights, performance issues, or physical damage), and the dates and mileage of any service visits related to the issue. If the problem is a warranty claim, know whether you are still under the basic warranty (typically three years or 36,000 miles) or powertrain warranty (typically five years or 60,000 miles). If you have already taken the vehicle to a dealer for repair, bring the service tickets or work orders.

Complaints About Dealer Service or Sales

If your complaint is about how a dealer treated you—overcharging for repairs, refusing to honor warranty coverage, high-pressure sales tactics, or poor service—start with the dealer's management. Ask to speak with the service manager (for service issues) or the general manager (for sales or conduct issues). Explain the problem clearly and say what resolution you want: a refund, a repair at no charge, or a credit toward future service.

Give the dealer a reasonable window to respond—usually 10 to 14 business days. If the dealer does not resolve it, contact GM's regional customer service office. You can find the regional office for your area by calling 1-800-462-8342 and asking for the regional customer relations manager. Some states also have dealer licensing boards or attorney general offices that handle dealer complaints; these agencies can investigate independently of GM.

How to Report a Safety Defect to NHTSA

If you believe your vehicle has a safety defect—a problem with brakes, steering, airbags, seatbelts, or any system that affects safe operation—you can report it to NHTSA's Office of Defects Investigation. This is separate from complaining to GM, and NHTSA tracks complaints to identify patterns. If enough complaints come in about the same issue, NHTSA can open an investigation and require GM to issue a recall.

Go to safercar.gov and click "Report a Safety Problem." You will need your VIN, a description of the defect, and details about when it occurred. You can also call NHTSA's hotline at 1-888-327-4236 to report by phone. NHTSA does not repair vehicles or award compensation, but a complaint on record can support your case if you later pursue a lemon law claim or small claims court action.

Understanding GM's Response Timeline

After you file a complaint with GM's Customer information Center, expect an initial response within 5 to 10 business days. A representative will review your case, pull your service history, and may ask you to bring the vehicle in for a diagnostic inspection at a GM dealer. GM typically does not charge for this inspection if the vehicle is under warranty.

If the inspection confirms a defect covered by warranty, GM will authorize the dealer to repair it at no cost. If the defect is not covered by warranty but GM determines it is a known issue affecting multiple vehicles, GM may still authorize a repair as a goodwill gesture. If GM denies your complaint, they will explain their reason in writing. At that point, you can request escalation to a higher level of review or explore other options like arbitration or lemon law claims.

Lemon Law Claims and Arbitration

If a vehicle has a recurring defect that the dealer cannot fix after multiple attempts, you may have a claim under your state's lemon law. Lemon laws vary by state, but most require that the defect occur within a certain timeframe (often the first year or 12,000 miles) and that the dealer has had at least three attempts to repair it. Some states allow you to pursue a lemon law claim while GM's complaint is still pending.

GM also participates in the Better Business Bureau's Auto Line arbitration program in some states. This is a free, informal process where an arbitrator hears both sides and makes a binding decision. If you want to pursue arbitration, ask GM's customer service representative about it, or contact your local Better Business Bureau. Arbitration is faster than small claims court but does not allow you to recover attorney fees.

Documenting Your Complaint for Future Use

Keep a file with every piece of communication about your vehicle problem. This includes service tickets from the dealer, photos or videos of the defect, copies of your warranty documents, notes from phone calls with GM (write down the date, time, representative's name, and what was discussed), and any written responses from GM. If the problem persists and you later file a lemon law claim or take GM to small claims court, this documentation will be your evidence.

When you call GM or visit the dealer, ask for a case or reference number. Write it down and use it in all future communications. If you send a written complaint by mail, use certified mail with return receipt so you have proof GM received it. These steps may seem tedious, but they protect you if the complaint escalates.

Frequently Asked Questions

How long does GM have to respond to a complaint?

GM's Customer information Center typically responds within 5 to 10 business days. However, the full resolution—including any diagnostic inspection or repair—can take several weeks. If you do not hear back within two weeks, call 1-800-462-8342 and reference your case number to check on the status.

Can I complain about a used GM vehicle I bought from a private seller?

GM's complaint process is primarily for vehicles purchased through GM dealers or with GM financing. If you bought a used vehicle privately, your recourse depends on your state's lemon law (some cover used vehicles within a certain timeframe) and whether you have a written warranty. You can still report a safety defect to NHTSA regardless of how you purchased the vehicle.

What if my complaint is about a recall repair that was done incorrectly?

Contact the dealer that performed the recall work and ask them to redo it. If the dealer refuses or the problem persists after a second attempt, escalate to GM's regional customer relations office. You can also report the issue to NHTSA, which tracks complaints about recall repairs and can investigate if a pattern emerges.

Do I need a lawyer to file a complaint with GM?

No. You can file a complaint directly with GM by phone or mail at no cost. However, if you are considering a lemon law claim or small claims court action, consulting a lawyer who specializes in lemon law can help you understand your rights and whether you have a strong case.

Can I get a refund or replacement vehicle through GM's complaint process?

GM's primary goal is to repair the defect under warranty. If the defect cannot be fixed after multiple attempts, some states' lemon laws allow you to demand a refund or replacement, but this is not GM's decision alone—it depends on your state's law and whether you meet the legal threshold for a lemon law claim.
