When Is a Car a Lemon in Wisconsin?
Wisconsin's Lemon Law thresholds — 4 attempts or 30 cumulative calendar days OOS, plus written election triggering the 30-day clock and automatic doubling on non-compliance.
A vehicle qualifies as a “lemon” under Wisconsin’s Wis. Stat. § 218.0171(1)(h) when:
The thresholds
| Test | Threshold |
|---|---|
| Same nonconformity, repair attempts | 4 or more |
| Cumulative calendar days out of service | 30 or more |
PLUS:
- Defect substantially impairs use, value, or safety.
- Within the 1-year window (or end of express warranty).
- Written election sent to manufacturer.
What happens after thresholds are met
- Write election — refund or replacement.
- 30-day clock starts on manufacturer’s receipt.
- Manufacturer must comply within 30 days.
- Day 31 — automatic § 218.0171(7) doubling if not fully delivered.
What counts as a “repair attempt”
- Vehicle was at an authorized service facility.
- Consumer reported the defect.
- Repair order documents the visit.
- “No problem found” visits count.
- Different symptoms in the same visit can count separately.
- Independent-mechanic visits don’t count.
- Routine maintenance doesn’t count.
What “substantially impairs” means
Three-prong test (use OR value OR safety) — typical examples that qualify:
- Stalling.
- Brake failure.
- Steering failure.
- Transmission slipping.
- Engine fires.
- Phantom braking.
- HVAC defroster system failure (critical in Wisconsin winter).
Bottom line
If you’ve had four repair attempts on the same defect or 30+ cumulative calendar days out of service — within the 1-year window — you likely qualify. Send the written election and start the 30-day clock. Get a free case review to confirm and ensure precise 30-day clock documentation.
