The Law: Wisconsin Lemon Law and Double Damages
The statutes behind a Wisconsin lemon-law claim — § 218.0171 Lemon Law (with automatic double damages), Magnuson-Moss, and timing rules.
Wisconsin’s consumer-protection framework for defective vehicles is anchored by the § 218.0171 Lemon Law itself — which has a built-in damage multiplier (automatic double damages on 30-day non-compliance) and mandatory attorney fees, making it one of the few state Lemon Laws with both features in the statute itself.
The two pillars
- Wisconsin Lemon Law — Wis. Stat. § 218.0171. Refund or replacement; automatic double damages on 30-day non-compliance; mandatory attorney fees under § 218.0171(7). 1-year Rights Period; 4-attempt / 30-day OOS thresholds.
- Federal Magnuson-Moss Warranty Act — 15 U.S.C. § 2301 et seq. Civil court; § 2310(d)(2) attorney fees; federal-court access (E.D. Wis. — Milwaukee, Green Bay; W.D. Wis. — Madison).
Wisconsin is unusual in that the Lemon Law itself does so much of the damage-and-fee work that a separate state UDAP overlay (like Colorado’s CCPA or Massachusetts’s c. 93A) is less essential. The Wisconsin Consumer Act (Wis. Stat. § 421) is primarily consumer credit-focused and rarely deployed for vehicle defect cases.
Topics in this section
- Wisconsin Lemon Law statute (§ 218.0171) — Core eligibility, 1-year window, mandatory § 218.0171(7) attorney fees.
- Automatic double damages — The § 218.0171(7) doubling mechanism and Marquez v. Mercedes-Benz USA (2012 WI 57).
- Magnuson-Moss Warranty Act — Federal overlay.
- Repair-attempt presumption — The 4-attempt and 30-day OOS thresholds plus written election.
- Statute of limitations — Timing under each statute.
Why the § 218.0171 Lemon Law is unusually strong
Wisconsin’s Lemon Law has:
- Automatic statutory double damages on 30-day non-compliance — no willfulness required.
- Mandatory attorney fees on prevailing.
- Marquez strict-construction precedent — manufacturers cannot avoid doubling through substantial compliance.
This combination makes Wisconsin one of the strongest consumer-protection states for motor-vehicle warranty claims, despite the tight 1-year Rights Period.
Magnuson-Moss adds federal-court access (E.D. Wis. — Milwaukee, Green Bay; W.D. Wis. — Madison) and an additional fee-shifting basis under § 2310(d)(2) — but the Wisconsin Lemon Law’s own provisions typically dominate fee/damage recovery.
How they interact procedurally
Wisconsin consumers must navigate:
- Manufacturer-required informal dispute settlement procedure (if one is certified under § 218.0171(2)(c)) — typically BBB Auto Line.
- Written election of refund or replacement.
- 30-day clock for manufacturer to deliver elected remedy.
- Court action — Wisconsin Circuit Court or federal court (E.D./W.D. Wis.) under Magnuson-Moss concurrent jurisdiction. Automatic double damages attach if 30-day window missed.
