Michigan Lemon Law: What Qualifies and How to Get a Refund or Replacement (2026)

Michigan has one of the longest lemon law protection periods in the United States. Under MCL § 257.1401 et seq., new vehicle buyers and demo car purchasers have up to 4 years or 50,000 miles to file a lemon law claim—whichever comes first. This extended coverage gives Michigan drivers a significant advantage when dealing with defective vehicles. If your car develops a serious defect and the manufacturer can’t fix it after a reasonable number of repair attempts, you’re entitled to a full refund or replacement vehicle.

With the requirement for BBB Auto Line arbitration before litigation and strong attorney fee recovery, Michigan’s lemon law offers practical and affordable pathways to justice for buyers stuck with defective cars.

Michigan Lemon Law: Key Facts

What Qualifies as a Lemon in Michigan

A vehicle qualifies as a lemon if it has a defect that impairs its use, value, or safety and that defect:

• Occurs within the coverage period (4 years or 50,000 miles)
• Is covered under the manufacturer’s warranty
• Cannot be repaired after reasonable attempts by an authorized dealer
• Is not caused by abuse, neglect, or unauthorized modifications

Michigan law defines “reasonable attempts” as:

• 4 repair attempts for the same defect, OR
• 1 repair attempt if the defect creates an imminent safety hazard (such as brake failure, steering problems, or faulty airbags), OR
• The vehicle is out of service for 30 cumulative days during the warranty period, even if different defects are involved

The extended 4-year/50,000-mile timeframe is generous compared to most states and gives Michigan buyers considerable protection.

How to Document Your Lemon Claim

Proper documentation is essential for a successful lemon law claim. Maintain records of:

• All repair orders and invoices: Obtain copies from the dealership showing the date, mileage, defect description, and work performed
• Warranty documentation: Keep your purchase agreement, original warranty booklet, and any extended warranty papers
• Communication logs: Document all phone calls with dealer service departments and the manufacturer (date, time, person spoken with, summary of conversation)
• Defect timeline: Note when the problem first occurred, when you first reported it, and dates of all subsequent repair attempts
• Out-of-service calculation: Track the total number of days the vehicle was with the dealer for repairs
• Photos and videos: Document the defect if visible (warning lights, mechanical issues, etc.)
• Written correspondence: Keep copies of emails and letters sent to the dealer or manufacturer

How to File a Lemon Law Claim in Michigan

Step 1 — Send Written Notice to the Manufacturer

Send a formal notice to the manufacturer’s zone representative or headquarters. The notice should include:

• Your full name, address, and phone number
• Vehicle identification number (VIN), year, make, model, and current mileage
• Date of original purchase and delivery
• Detailed description of the defect(s)
• Dates and results of all repair attempts (with copies of service records)
• Statement that repairs have been unsuccessful
• Request for either a refund or replacement vehicle
• Reasonable deadline for response (typically 10 business days)

Send via certified mail with return receipt requested.

Step 2 — Attempt Manufacturer Arbitration (BBB Auto Line)

Michigan law requires BBB Auto Line arbitration before filing a lawsuit. After the manufacturer receives your notice:

• The manufacturer has one final opportunity to repair the vehicle
• If the repair fails or is refused, either party can request BBB Auto Line arbitration
• At arbitration, both you and the manufacturer present evidence to a neutral arbitrator
• The arbitrator determines whether the vehicle qualifies as a lemon and awards refund, replacement, or repair
• The arbitration decision is binding on the manufacturer but you can appeal in court if you disagree

File your arbitration claim through the BBB Auto Line by visiting www.bbbautoline.org or calling the program office.

Step 3 — File a Lawsuit (If Necessary)

If arbitration doesn’t resolve the claim or you disagree with the decision:

• File a lawsuit in District Court (for claims under $25,000) or Circuit Court
• Your attorney can recover all attorney fees and court costs if you win
• You may also pursue claims in small claims court if eligible

Real Situations in Michigan

Detroit: A buyer purchased a 2023 Ford F-150 that experienced repeated transmission failures within the first year and 22,000 miles. After 4 repair attempts at the Ford dealership, the transmission continued to slip and hesitate. The buyer sent formal notice to Ford and pursued BBB Auto Line arbitration. The arbitrator ruled in the buyer’s favor, and Ford issued a full refund of the $48,000 purchase price.

Grand Rapids: A buyer bought a 2022 Chevrolet Traverse that spent a cumulative 35 days in the dealer service department for various electrical and mechanical issues within 18 months and 25,000 miles. Although different defects were involved, Michigan’s “30 days out of service” rule applied. The buyer filed for lemon law protection and accepted a replacement vehicle of equal value from Chevrolet.

Ann Arbor: A buyer purchased a 2023 Honda CR-V that developed a serious brake warning system failure within the first 3 months. This safety issue triggered the “1 attempt” rule. After the initial repair failed, the buyer documented the defect and sent notice to Honda. Rather than proceed to arbitration, Honda proactively settled with a full refund.

Common Mistakes Michigan Lemon Law Buyers Make

• Not pursuing arbitration: Michigan requires BBB Auto Line arbitration before litigation. Skipping this step delays resolution and may complicate later court proceedings.
• Mixing defects without tracking days out of service: While Michigan counts repair days even for different defects, buyers often fail to add up total days out of service. Keep a running tally to reach the 30-day threshold if needed.
• Failing to send formal written notice: Informal complaints to the dealer or manufacturer won’t start the lemon law clock. You must send a formal written notice via certified mail to create legal documentation.
