Michigan Lemon Law

Michigan’s lemon law — formally the New Motor Vehicle Warranty Act — is codified at Mich. Comp. Laws § 257.1401 et seq. It is court-driven (subject to a mandatory manufacturer informal dispute settlement procedure under § 257.1407(1) if one is certified) and uses a notably shorter eligibility window than most major states: defects must be reported within one year of delivery or before the express warranty expires, whichever is earlier.

Michigan presents a unique problem among major lemon-law states: the Michigan Consumer Protection Act (MCPA) has been functionally narrowed by the Michigan Supreme Court’s interpretation in Smith v. Globe Life Insurance Co., 460 Mich. 446 (1999). The court read MCL § 445.904(1)(a)‘s regulated-industry exemption broadly to exempt any transaction “specifically authorized” by federal or state law — and follow-on cases like Liss v. Lewiston-Richards, Inc., 478 Mich. 203 (2007) extended that narrowing. As a practical matter, MCPA’s reach for motor-vehicle warranty cases is limited and contested, meaning Michigan consumers don’t get the same automatic treble-damages overlay that North Carolina UDTPA, Ohio CSPA, or Georgia FBPA provides. This makes the federal Magnuson-Moss Warranty Act structurally load-bearing for Michigan attorney-fee recovery.

Who’s protected

Michigan’s Lemon Law covers:

• New motor vehicles purchased or leased in Michigan for personal, family, or household use.
• Demonstrators sold under new-vehicle warranties.
• Subsequent transferees during the warranty period.

Coverage is defined by vehicle type, not weight. Under MCL § 257.1401, a “motor vehicle” is one designed as a passenger vehicle or sport-utility vehicle; the statute excludes motor homes, buses, trucks other than pickup trucks and vans, and vehicles designed to travel on fewer than 4 wheels (motorcycles). There is no GVWR weight cap.

The 1-year window

Michigan’s eligibility window under MCL § 257.1402 requires the defect to be reported within one year of delivery — or before the express warranty expires, whichever is earlier. This is shorter than most major states:

• Georgia, North Carolina, Texas: 24 months / 24,000 miles
• Ohio: 12 months / 18,000 miles
• Illinois, Pennsylvania: 12 months / 12,000 miles
• Michigan: 1 year (no mileage cap)

Michigan has no mileage cap within the 1-year window, which is unusual. The defect simply needs to be reported within one year — the repair attempts and court action can occur later, provided they’re within the statute of limitations.

Outside the 1-year reporting window, Magnuson-Moss (4 years from delivery) remains available. MCPA’s narrowed status makes it a less reliable backup than peer-state consumer-protection acts.

The “reasonable number of attempts” test

Michigan applies thresholds under MCL § 257.1403:

• Four or more repair attempts for the same nonconformity; OR
• 30 or more cumulative days out of service for repair.

See our repair-attempt presumption article.

The certified-mail notice requirement

Before invoking Lemon Law remedies, the consumer must serve written notice by certified mail to the manufacturer under MCL § 257.1403(1). The manufacturer then has a reasonable opportunity (typically 5 business days) to designate a repair facility and an additional reasonable time for the final repair. See how-to-file article.

The mandatory informal dispute settlement procedure

Under MCL § 257.1407(1), if the manufacturer has established an informal dispute settlement procedure that meets federal 16 C.F.R. Part 703 requirements, the consumer must use it before filing court action. This is most commonly BBB Auto Line for participating manufacturers. See manufacturer arbitration article.

What you can recover

A successful Michigan Lemon Law case typically produces:

• Refund — purchase price, taxes, fees, financing charges, minus reasonable use deduction.
• Replacement — comparable new vehicle.
• Attorney fees under § 257.1407(2) — discretionary (“the court may award”).
• Reimbursement of incidental damages.

The Lemon Law itself does not include treble damages or punitive damages.

The Magnuson-Moss two-track approach

Because MCPA’s reach is limited and § 257.1407(2) Lemon Law attorney fees are discretionary, federal Magnuson-Moss claims are the primary fee-recovery engine in Michigan lemon-law cases. Magnuson-Moss provides:

• Mandatory attorney fees under 15 U.S.C. § 2310(d)(2).
• Federal-court access (Eastern or Western District of Michigan) for amounts over $50,000.
• 4-year limitations under Michigan UCC § 440.2725.

Most experienced Michigan lemon-law strategy pairs the Lemon Law with Magnuson-Moss in federal court for the fee-shifting hook.

What to do next

1. Document everything. See our evidence guide.
2. Report the defect within 1 year of delivery — the reporting deadline is unforgiving.
3. Send certified-mail notice to the manufacturer.
4. Use BBB Auto Line if manufacturer has a certified IDS procedure (mandatory under § 257.1407(1)).
5. File court action with parallel Magnuson-Moss claims.
6. Get a free case review from a Michigan lemon-law attorney.
