Dear Sir or Madam:
This law firm represents [CONSUMER FULL NAME] ("Consumer" or "Client") regarding the above-described vehicle, which qualifies as a "lemon" under the Wisconsin Motor Vehicle Lemon Law, Wis. Stat. § 218.0171, and the federal Magnuson-Moss Warranty Act, 15 U.S.C. § 2301 et seq.
This letter constitutes the mandatory written notice of nonconformity required by Wis. Stat. § 218.0171(3) and demands repurchase or replacement of the defective vehicle. The manufacturer has one (1) final repair opportunity as provided by the statute. Time is of the essence.
I. WISCONSIN LEMON LAW — KEY PROVISIONS THAT DISTINGUISH WISCONSIN FROM OTHER STATES
A. Leased Vehicles Are Fully Covered
Wisconsin's Lemon Law expressly covers leased vehicles, not just purchased ones. Under Wis. Stat. § 218.0171(1)(d), "motor vehicle" includes any new motor vehicle that is "the subject of a retail purchase or retail lease in this state." Many states exclude leased vehicles; Wisconsin does not. Our Client's vehicle is a ☐ purchased / ☐ leased vehicle and is fully protected under Wis. Stat. § 218.0171.
B. The Coverage Period — One Year from Delivery (Shorter Than Most States)
The Wisconsin Lemon Law's coverage period is the earlier of: (a) the full term of the manufacturer's express warranty, or (b) one (1) year from the date of original delivery to the consumer. Wis. Stat. § 218.0171(2)(a). This is a shorter coverage window than many states' lemon laws, which is why it is critical to act promptly once defects arise. All nonconformities described in this letter first manifested within the coverage period.
C. Reduced Safety Defect Threshold — Only 2 Repair Attempts Required
Wisconsin imposes a reduced threshold for safety defects: under Wis. Stat. § 218.0171(2)(b)1m, if a nonconformity is one that is likely to cause death or serious bodily harm if the vehicle is driven, the presumption of lemon status is established after only two (2) repair attempts. This lower threshold reflects Wisconsin's particularly consumer-protective approach.
For non-safety defects, the standard threshold under Wis. Stat. § 218.0171(2)(b)1 is four (4) repair attempts for the same defect, or thirty (30) or more calendar days out of service.
D. Consumer Chooses the Remedy — Refund or Replacement
Under Wis. Stat. § 218.0171(2)(b)3, the consumer — not the manufacturer — chooses whether to receive a full refund or a comparable replacement vehicle. The manufacturer cannot dictate the remedy. Our Client elects the remedy identified in Section VIII below.
E. No Mandatory Arbitration Before Filing Suit
Wisconsin is one of a limited number of states that does not require consumers to submit to manufacturer-sponsored arbitration before filing a civil action in court. Wis. Stat. § 218.0171(6) allows the consumer to elect to use any informal dispute settlement mechanism established by the manufacturer, but this election is entirely voluntary. Our Client ☐ elects / ☐ does not elect to use manufacturer arbitration and ☐ will / ☐ will not proceed directly to court if this demand is not resolved.
F. Mandatory Attorney's Fees — No Discretion
Under Wis. Stat. § 218.0171(7), if the consumer prevails in a civil action, the court shall (mandatory, not discretionary) award the consumer reasonable attorney's fees and costs. This fee-shifting provision is one of the strongest in the country.
G. Civil Forfeiture for Manufacturer Non-Compliance
Under Wis. Stat. § 218.0171(8), any manufacturer who violates the Lemon Law may be subject to a civil forfeiture of $100 to $10,000 per violation, in addition to the consumer's individual relief. This forfeiture is payable to the State of Wisconsin and may be sought by the Wisconsin Department of Justice.
H. Mileage Offset Calculation
Wisconsin's refund formula includes a mileage offset calculated as:
Offset = (Full Purchase Price) × (Miles at First Report of Nonconformity ÷ 100,000)
This calculation is set by statute at Wis. Stat. § 218.0171(2)(b)3.a. The offset is based on miles at the time of the first written report of the nonconformity, not current mileage. Accordingly, it is essential that the mileage at first complaint be accurately documented.

WISCONSIN-SPECIFIC PRACTICE NOTES
-
Safety Defect — Act Immediately: The two-repair threshold for safety defects under Wis. Stat. § 218.0171(2)(b)1m is significantly lower than other states. If the defect is safety-related (brake failure, steering loss, fire risk, etc.), qualification for lemon law relief may occur after just two unsuccessful repairs.
-
Leased Vehicle Documentation: For leased vehicles, secure the lease agreement, capitalized cost disclosure, and any residual value documentation. The refund formula under Wis. Stat. § 218.0171(2)(b)3 applies to both purchases and leases.
-
One-Year Coverage Period: Wisconsin's one-year coverage window is shorter than many states. Clients who delay beyond one year from delivery lose their Wis. Stat. § 218.0171 rights, even if the manufacturer's warranty is longer. File promptly.
-
Consumer Elects the Remedy: The manufacturer cannot override the consumer's election between refund and replacement under Wis. Stat. § 218.0171(2)(b)3. Document the election clearly in writing.
-
No Mandatory Arbitration: Wisconsin does not require manufacturer arbitration before suit. This is a significant strategic advantage — consumers can proceed directly to court without delay.
-
Mandatory Fee Award: Because attorney's fees are mandatory (not discretionary) under Wis. Stat. § 218.0171(7), manufacturers face substantial exposure if they litigate and lose. Use this as a settlement lever.
-
Wisconsin DOJ Role: The Wisconsin Department of Justice can independently pursue civil forfeitures against non-compliant manufacturers under Wis. Stat. § 218.0171(8). A contemporaneous DOJ complaint can increase pressure on the manufacturer.
-
Mileage at First Complaint — Key Date: Document the odometer reading at the first written complaint to the dealer. This reading is used in the statutory offset formula and should be preserved from the first repair order.

About This Template
A demand letter is a formal written request to fix a problem or pay what is owed, sent before anyone files a lawsuit. It gives the other side a real chance to settle, creates a record of your attempt to resolve things, and in many cases (unpaid debts, insurance claims, broken contracts) starts a legally required response window. A well-written demand letter lays out what happened, what you want, and a deadline to act, which is often enough to get results without ever going to court.
Important Notice
This template is provided for informational purposes. It is not legal advice. We recommend having an attorney review any legal document before signing, especially for high-value or complex matters.
