When Is a Car a 'Lemon' in Michigan?
Michigan Lemon Law defines a lemon as a vehicle with a substantial defect reported within 1 year of delivery, with four repair attempts or 30 days out of service.
The short answer: a vehicle becomes a “lemon” under the Michigan Lemon Law when the manufacturer has had a reasonable number of attempts to repair a substantial defect — and the defect was reported within one year of delivery — and the consumer has served certified-mail notice plus a final repair opportunity.
The legal test
Under MCL § 257.1403:
- Substantial impairment of use or value (§ 257.1401(g)).
- Reasonable number of repair attempts.
- Personal, family, or household use.
- Defect reported within 1 year of delivery (the unique Michigan deadline).
- Covered vehicle type — passenger vehicle, SUV, pickup, or van (motor homes, buses, heavy trucks, and motorcycles excluded; no GVWR weight cap).
What counts as a “substantial” defect
See qualifying defects for common categories.
What counts as a “reasonable number of attempts”
- Four or more repair attempts for the same defect, OR
- 30 or more cumulative days out of service.
The 1-year reporting window — Michigan’s tightest requirement
Michigan has the shortest reporting deadline of any major lemon-law state. The defect must be reported to the manufacturer or dealer within 1 year of delivery under MCL § 257.1402. A defect that first manifests at month 13 is not a Lemon Law case — only Magnuson-Moss and (in limited cases) MCPA remain.
The mandatory certified-mail notice
Even after meeting the threshold, the consumer must send certified-mail notice with a final repair opportunity before invoking remedies.

- Defect was reported within 1 year of delivery.

What if you’re past the 1-year reporting window?
Magnuson-Moss (4-year limit) provides the primary remedy. MCPA (6-year limit) may apply with the Smith v. Globe Life narrowing caveat.
