Where to file a car complaint depends on what went wrong and who you're complaining about

A car complaint can go to your state's attorney general, your state's consumer protection agency, the Federal Trade Commission (FTC), the National Highway Traffic Safety Administration (NHTSA) if it involves safety, or your state's motor vehicle department depending on whether the problem is with the dealer, the manufacturer, or the vehicle itself. The route matters because different agencies have different powers — some can force refunds or recalls, others can only investigate and publish findings.

Start by identifying who caused the problem. If a dealer sold you a defective car or misrepresented it, your state's attorney general or consumer protection office is usually the fastest path. If the manufacturer built a defective part into the car, NHTSA handles safety complaints and can order recalls. If you're complaining about a repair shop, your state's motor vehicle department or licensing board may oversee them. If you're disputing a charge or financing term, the Consumer Financial Protection Bureau (CFPB) takes complaints about lenders and credit reporting.

Key Takeaways

  • Safety defects go to NHTSA (safercar.gov), which can order recalls; other problems go to your state attorney general or consumer protection agency.
  • You will need the vehicle identification number (VIN), the date you bought or discovered the problem, and documentation of what went wrong — repair receipts, photos, or written correspondence with the dealer.
  • Most state agencies and the FTC accept complaints online and do not require a lawyer; filing is free.
  • Response time varies from two weeks to several months depending on the agency and the complexity of the complaint.
  • Filing a complaint does not automatically get you money back, but it creates an official record that can support a small claims case or lemon law claim.

NHTSA complaints for safety defects and recalls

The National Highway Traffic Safety Administration (NHTSA) is the federal agency that investigates safety defects in cars. If your complaint involves a safety problem — brakes failing, airbags not deploying, steering loss, fire, or a defect that could cause injury — file with NHTSA at safercar.gov. You can file online, by phone at 1-888-327-4236, or by mail. NHTSA does not handle cosmetic problems, poor fuel economy, or comfort issues.

When you file, include the VIN, the year and model, the current mileage, a description of what happened, and when it happened. If you have repair records showing the dealer or manufacturer acknowledged the problem, attach them. NHTSA will assign your complaint a number and may contact you for more details. If enough complaints come in about the same defect, NHTSA can open an investigation and order a recall. You will not get money directly from NHTSA, but a recall can force the manufacturer to repair or replace the vehicle at no cost to you.

State attorney general and consumer protection complaints

Your state's attorney general or consumer protection office handles complaints about dealers, manufacturers, and repair shops that involve fraud, misrepresentation, or breach of warranty. These agencies can investigate, negotiate on your behalf, and in some cases force a refund or settlement. Most states accept complaints online through their website; search "[your state] attorney general complaint" or "[your state] consumer protection complaint."

You will need the business name and address, the VIN or description of the vehicle, the date of purchase or service, what was promised versus what happened, and copies of any written agreements, receipts, or correspondence. Some states have a lemon law that requires manufacturers to buy back or replace vehicles with repeated defects; filing a complaint with your attorney general creates an official record that supports a lemon law claim. Response time is typically two to eight weeks, though complex cases take longer.

Federal Trade Commission (FTC) complaints

The FTC handles complaints about deceptive advertising, financing fraud, and unfair business practices by dealers and manufacturers. File at reportfraud.ftc.gov. The FTC does not resolve individual disputes but uses complaints to identify patterns and take action against companies that harm many consumers. Your complaint becomes part of a public database that other consumers, regulators, and attorneys can search.

Include the business name, what was advertised or promised, what actually happened, and when. If you were charged hidden fees, misled about financing terms, or sold a vehicle with undisclosed damage, the FTC wants to know. You will not receive a direct response from the FTC about your individual case, but if the agency finds a pattern of fraud, it can sue the company and force restitution to affected consumers.

Motor vehicle department and repair shop complaints

If your complaint is about a repair shop — overcharging, doing unnecessary work, or poor repairs — contact your state's motor vehicle department or the licensing board that oversees repair shops. Some states have a separate automotive repair board; others handle it through the attorney general's office. Search "[your state] repair shop complaint" to find the right agency.

You will need the shop's name and address, the date of service, an itemized receipt, and a description of what went wrong. If you took the vehicle to another shop and got a second opinion showing the first shop overcharged or did unnecessary work, bring that documentation. Some states can order the shop to refund money or redo the work; others can suspend or revoke the shop's license if complaints are serious enough.

Consumer Financial Protection Bureau (CFPB) for financing and credit issues

If your complaint involves how you were financed, the terms of a loan, credit reporting errors related to a car purchase, or a dispute with a lender or credit company, file with the Consumer Financial Protection Bureau at consumerfinance.gov/complaint. The CFPB handles complaints about banks, credit unions, finance companies, and credit reporting agencies.

Describe what happened, when it happened, and what you tried to do to resolve it. Include the lender's name, the loan amount, and any written correspondence. The CFPB will send your complaint to the company and give them 15 days to respond. You will receive a copy of their response. If the company does not respond or you disagree with the response, you can submit a rebuttal. The CFPB publishes complaint data and uses it to identify companies that need enforcement action.

What to include in any car complaint

Regardless of which agency you file with, gather these documents before you start: the vehicle identification number (VIN), the purchase date and price, the dealer or manufacturer name and address, a timeline of what went wrong and when, repair receipts or invoices, photos of damage or defects, written correspondence with the dealer or manufacturer, and the current status of the vehicle (still owned, traded in, sold, in repair).

Write a clear, factual description of the problem. Stick to what happened, not opinions. Instead of "the car is a lemon," write "the transmission failed at 15,000 miles, the dealer replaced it under warranty, it failed again at 22,000 miles, and the dealer has refused to replace it a second time." Include dates, mileage, and specific actions taken. The more specific you are, the more seriously the agency will treat your complaint.

What happens after you file

After you file, the agency will assign your complaint a reference number and may contact you for more information. Some agencies acknowledge receipt within a few days; others take longer. If the complaint goes to a business, that business typically has 15 to 30 days to respond. You may receive a response from the business before you hear from the agency.

Filing a complaint does not automatically get you money back or force a repair. It creates an official record. That record can support a small claims case, a lemon law claim, or a lawsuit. If many people file the same complaint about the same defect, the agency may open an investigation or take enforcement action against the company. Some agencies publish complaint data publicly, which can pressure companies to change their practices.

Frequently Asked Questions

Do I need a lawyer to file a car complaint?

No. All the agencies listed here accept complaints directly from consumers at no cost. You can file online, by phone, or by mail without a lawyer. However, if you want to pursue a lawsuit or a lemon law claim, consulting a lawyer who handles consumer or automotive law may be worth the cost.

Can I file a complaint if I already sold the car?

Yes. You can file a complaint about a defect that existed when you owned it, even if you no longer own the vehicle. Include the sale date and the name of the buyer if you know it. The complaint still creates an official record and may support a claim against the dealer or manufacturer.

What's the difference between filing with my state and filing with a federal agency?

State agencies (attorney general, consumer protection) focus on fraud and deception by the business and can often negotiate refunds or settlements. Federal agencies (NHTSA, FTC, CFPB) investigate patterns of harm across many consumers and can take enforcement action against companies. Filing with both is allowed and sometimes recommended.

How long does it take to get a response?

Response time varies. NHTSA typically acknowledges safety complaints within a few days. State attorney general offices may take two to eight weeks. The FTC does not respond to individual complaints but uses them for enforcement. The CFPB requires companies to respond within 15 days, and you will receive a copy.

What if the company disputes my complaint?

The agency will investigate both sides. If you have documentation — repair receipts, photos, written correspondence — include it with your complaint. If the company's response contradicts yours, the agency may ask for more evidence from both parties. You can submit a rebuttal if you disagree with the company's response.
