The Michigan Lemon Law (MCL § 257.1401)

The Michigan New Motor Vehicle Warranty Act — commonly called the Michigan Lemon Law — is codified at MCL § 257.1401 et seq. Michigan’s framework pairs a relatively narrow 1-year reporting window with a moderate set of remedies — refund or replacement plus discretionary attorney fees under § 257.1407(2). Because Michigan’s MCPA has been narrowed by case law, the federal Magnuson-Moss Warranty Act carries unusual weight as the primary attorney-fee engine.

The core promise

MCL § 257.1403 requires a manufacturer to refund or replace a new motor vehicle when:

• The manufacturer (or its authorized agent) cannot repair a defect or condition that substantially impairs the use or value of the vehicle within a reasonable number of attempts; AND
• The defect was reported to the manufacturer or its dealer within one year of delivery; AND
• The consumer has given written notice by certified mail and a reasonable opportunity to repair.

Who’s covered

The Act covers:

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

Coverage is defined by vehicle type, not weight. The “motor vehicle” definition in MCL § 257.1401 covers vehicles designed as passenger vehicles or SUVs and explicitly 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 reporting window — Michigan’s most distinctive feature

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 every other major lemon-law state:

• 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)

Two important nuances:

1. No mileage cap within the 1-year window — unusual. The defect simply needs to be reported within one year. A consumer driving 30,000 miles in the first year still gets full coverage if the defect was reported during that period.

2. “Reported” vs. “manifested” — what matters is whether the consumer reported the defect to a dealer within the 1-year window. The repair attempts and court action can occur after the 1-year mark, provided the original report was timely and the case is filed within the statute of limitations.

Beyond the 1-year reporting window, Magnuson-Moss and (with caveats) MCPA remain available.

What “substantial impairment” means

The Michigan Lemon Law defines a “defect” (§ 257.1401(g)) as one that substantially impairs the use or value of the vehicle. Two-prong test (use OR value) — slightly narrower than the three-prong “use, value, or safety” tests in Ohio or Georgia. Safety considerations factor into Michigan’s “use” prong because an unsafe vehicle cannot reasonably be used.

See our qualifying defects guide.

What “reasonable number of attempts” means

Michigan’s framework under MCL § 257.1403:

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

See our repair-attempt presumption article.

The certified-mail notice requirement

Before invoking Lemon Law remedies, the consumer must serve written notice to the manufacturer by certified mail (or another method that requires a return receipt) under MCL § 257.1403(1). The manufacturer then has a reasonable opportunity to designate a repair facility and an additional reasonable time for the final repair (typically 5 business days for designation, then a reasonable repair window).

Missing the certified-mail notice is a common procedural defect in Michigan Lemon Law cases.

The mandatory informal dispute settlement procedure

If the manufacturer has established a qualifying procedure under § 257.1407(1) (typically BBB Auto Line meeting 16 C.F.R. Part 703), the consumer must use it before filing suit. See manufacturer arbitration article.

What you can recover

• Refund — purchase price plus Michigan sales tax plus collateral 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.

§ 257.1407(2) discretionary attorney-fee shifting

MCL § 257.1407(2) provides:

The court may award reasonable attorney fees to a prevailing party.

The word “may” is the operative limit. Unlike Ohio’s mandatory § 1345.75 or North Carolina’s mandatory § 20-351.8(3), Michigan’s Lemon Law fee provision is discretionary. The word “prevailing party” also means a manufacturer that prevails could theoretically recover fees from a consumer — though this is rare in practice.

Because § 257.1407(2) is discretionary and MCPA is narrowed, Magnuson-Moss § 2310(d)(2) — which mandates attorney fees on prevailing — is the primary attorney-fee hook in Michigan lemon-law practice.

Court action

Michigan Lemon Law cases are pursued in Michigan Circuit Court. Magnuson-Moss provides concurrent federal-court jurisdiction (Eastern District of Michigan in Detroit, Western District in Grand Rapids) for cases over $50K. Federal-court filing is unusually common in Michigan compared to peer states because of Magnuson-Moss’s load-bearing role.

How Michigan compares to other states

State	Enforcement	Rights / reporting window	Same-defect attempts	Statutory attorney fees in lemon law	State consumer-protection act	Primary attorney-fee engine
Michigan	Court (after IDS if mandatory)	1 yr (no mileage cap)	4	Discretionary	MCPA (narrowed)	Magnuson-Moss (federal)
NC	Court (after BBB if mandatory)	24 mo/24K mi	4	Mandatory	UDTPA (mandatory treble)	NC Lemon Law + UDTPA
Georgia	State arb OR court	24 mo/24K mi	3	Discretionary	FBPA (treble)	FBPA + MMWA
Ohio	Court	12 mo/18K mi	3	Mandatory	CSPA (treble)	OH Lemon Law + CSPA
California	Court	4-yr SOL	2 (varies)	Mandatory	None equivalent	Song-Beverly
Texas	TxDMV	24 mo/24K mi	4	No	DTPA (treble)	DTPA
Florida	Mfr arb → NMVA	24 months	3	No	FDUTPA	FDUTPA + MMWA
New York	Court OR AG arb	2 yr/18K mi	4	Mandatory	§ 349 (3×)	NY Lemon Law + § 349
Illinois	Court	12 mo/12K mi	4	No	ICFA (treble)	ICFA
Pennsylvania	Court OR AG arb	12 mo/12K mi	3	Mandatory	UTPCPL (treble)	PA Lemon Law + UTPCPL

Bottom line

Michigan’s Lemon Law is moderate-strength on its own — refund/replacement plus discretionary attorney fees within a tight 1-year reporting window. The unique feature is the load-bearing role of federal Magnuson-Moss as the primary attorney-fee engine because MCPA has been narrowed by Smith v. Globe Life Insurance Co. (1999) and its progeny.
