State lemon law · checked October 23, 2026
Verified against the statute / official state publicationM.C.L. §§257.1401–257.1410
| Presumption window | Michigan's clock is unusual: the FIRST repair must happen within the warranty term or 1 year of delivery; the 4 attempts then have 2 years from the first attempt to accumulate. The 30 days out must fall inside the earlier of the warranty term or 1 year. |
|---|---|
| Same defect | 4+ repair attempts |
| Days out of service | 30+ calendar days |
The presumption is the set of numbers that shifts the burden to the manufacturer. A claim can exist outside the presumption — it is a shortcut, not the whole road. Read why.
Formula (refund only): (consumer miles before the first report of the defect + all miles beyond 25,000) ÷ 100,000 × purchase price. Miles between the first report and 25,000 are not charged.
After the 3rd repair attempt (or 25 days out of service), send written notice by return-receipt mail. The manufacturer must name an accessible repair facility, and then has 5 business days after you deliver the vehicle — the statutory last chance (§257.1403(5)).
Dispute route: If the manufacturer maintains a Part 703-compliant program, you must use it before the lemon law remedies apply.
Attorney's fees: Michigan makes manufacturers pay the consumer's attorney's fees in a successful claim.
Michigan's operative clocks are the first-repair window, the 2-year accumulation window for attempts, and the last-chance notice sequence.
