Wisconsin Lemon Law Guide: Your Rights Under Wisconsin Lemon Law
What Is the Wisconsin Lemon Law?
The Wisconsin Lemon Law, officially codified as Wisconsin Statute § 218.0171, is a vital piece of consumer protection legislation designed to safeguard individuals who purchase or lease new motor vehicles that turn out to be defective. When a consumer buys a new vehicle, they expect it to function properly and safely. However, manufacturing defects can and do occur, leaving consumers with a vehicle that is unreliable, unsafe, or significantly diminished in value. The Wisconsin Lemon Law provides a legal remedy for these situations, ensuring that consumers are not left bearing the financial burden of a manufacturer's mistakes.
This statute protects consumers by requiring manufacturers to either replace the defective vehicle or refund the purchase price if the vehicle cannot be repaired after a reasonable number of attempts. The law applies to individuals who purchase or lease a new motor vehicle in Wisconsin for purposes other than resale. It also extends protection to those to whom the vehicle is transferred during the express warranty period, provided the transfer is not for resale. The Wisconsin Department of Transportation (WisDOT) and the Department of Agriculture, Trade and Consumer Protection (DATCP) serve as key resources for consumers seeking information and assistance regarding their rights under this law. The DATCP acts as the state's primary consumer protection agency, offering guidance and a platform for filing complaints against unfair business practices.
Which Vehicles Qualify Under Wisconsin Statute § 218.0171?
Understanding which vehicles are covered under the Wisconsin Lemon Law is crucial for consumers seeking relief. The law is specific about the types of vehicles and the conditions under which they qualify for protection.
New vs. Used Vehicle Coverage
The Wisconsin Lemon Law primarily covers new motor vehicles. If you purchase or lease a new vehicle in Wisconsin and it develops a serious defect within the first year of operation and before the warranty expires, it may qualify as a lemon.
It is important to note that used vehicles are generally not covered under the Wisconsin Lemon Law. If you purchase a used vehicle and experience problems, you cannot seek a replacement or refund under this specific statute. However, used car buyers in Wisconsin are not entirely without recourse. They may have rights under the federal Magnuson-Moss Warranty Act or state dealer regulations, particularly if the dealer failed to conduct a mandatory safety inspection or provide an accurate "Wisconsin Buyers Guide" prior to the sale.
Leased Vehicle Coverage
Consumers who lease a new motor vehicle are afforded the same protections under the Wisconsin Lemon Law as those who purchase a vehicle outright. If a leased vehicle meets the criteria of a lemon, the lessee has the right to demand a replacement or a refund from the manufacturer, just as a purchaser would.
Mileage and Time Limitations
To qualify for protection under the Wisconsin Lemon Law, the defect (nonconformity) must occur and be reported within a specific timeframe. The law stipulates that the defect must arise during the vehicle's first year of operation and before the expiration of the manufacturer's express warranty. Furthermore, consumers have 36 months from the date of the vehicle's initial delivery to file a Lemon Law claim.
Vehicle Types Covered
The Wisconsin Lemon Law covers a broad range of motor-driven vehicles required to be registered in the state. This includes:
- Passenger cars
- Trucks
- Motorcycles
- Motor homes
- Demonstrator or executive-driven vehicles
However, the law explicitly excludes certain types of vehicles, such as mopeds, semitrailers, trailers designed for use with a truck or truck tractor, non-motorized recreational vehicles, off-road vehicles (ATVs and UTVs), snowmobiles, and boats. Heavy-duty vehicles with a gross vehicle weight rating of more than 10,000 pounds are covered but are subject to slightly different rules regarding the timeline for providing a replacement vehicle.
What Qualifies as a "Lemon" in Wisconsin?
Not every vehicle with a defect is considered a lemon under Wisconsin law. The statute establishes specific criteria that must be met for a vehicle to qualify for a replacement or refund.
Substantial Impairment Standard
The core requirement is that the vehicle must have a "nonconformity." A nonconformity is defined as a condition or defect that substantially impairs the use, value, or safety of the motor vehicle and is covered by an express warranty. Minor issues, such as an irritating rattle or a cosmetic flaw, typically do not meet this threshold. The defect must be significant enough to affect the vehicle's reliability, market value, or the safety of its occupants. Furthermore, defects resulting from abuse, neglect, or unauthorized modifications by the consumer are not covered.
The "Presumption" Threshold: Number of Repair Attempts
The Wisconsin Lemon Law requires consumers to give the manufacturer or its authorized dealer a "reasonable attempt to repair" the defect. The law presumes that a reasonable attempt has been made if the dealer fails four times to fix the same nonconformity within the vehicle's first year and before the warranty expires. If the vehicle has been brought in for repair for the exact same issue on four separate occasions and the problem persists, it meets the criteria for a lemon.
Days Out of Service Threshold
Alternatively, a vehicle can qualify as a lemon if it is out of service for an aggregate of at least 30 days due to warranty nonconformities during its first year and before the warranty expires. A vehicle is considered "out of service" if it is in the possession of the manufacturer or dealer for repairs, or if it is in the consumer's possession but cannot be used because of a defect that seriously affects safety or use, provided the dealer has attempted to repair it at least twice.
The Wisconsin Lemon Law Claims Process
Navigating the Lemon Law claims process requires careful documentation and adherence to statutory procedures.
Required Steps and Manufacturer Notification
If you believe your vehicle is a lemon, the first step is to report the problem to the manufacturer or an authorized dealer as soon as possible to allow them an opportunity to repair it. If the repair attempts fail to resolve the issue and the vehicle meets the statutory criteria, you must formally notify the manufacturer.
You must request that the manufacturer either replace the vehicle or provide a refund. The Wisconsin Department of Transportation provides a form, the Motor Vehicle Lemon Law Notice and Nonconformity Report (MV2691), which can be used for this purpose. This notice should be sent directly to the manufacturer, preferably by Certified Mail, to ensure proof of delivery.
Documentation Requirements
Thorough documentation is essential for a successful Lemon Law claim. You should maintain meticulous records, including:
- Repair Orders from the dealer for every service visit, detailing the reported problems and the dates the vehicle was in the shop.
- A log of the dates the vehicle was out of service and the specific defects causing the downtime.
- Copies of the purchase contract, warranty information, and all correspondence with the manufacturer or dealer.
Arbitration Requirements
If the manufacturer denies your claim or fails to provide a satisfactory resolution, you may need to pursue arbitration. Arbitration is an informal dispute resolution process where an impartial third party reviews the case and makes a decision.
In Wisconsin, if a manufacturer has an arbitration program that is certified by the Wisconsin Department of Transportation, you are required to use that program before you can file a lawsuit under the Lemon Law. If the manufacturer's program is not certified, participation is optional. Arbitration is generally free for the consumer and does not require legal representation, though having an attorney can be beneficial.
Timeline Expectations
Once the manufacturer receives your formal Lemon Law claim requesting a replacement vehicle, they have 30 days to agree in writing to provide a comparable new vehicle. Following this agreement, they have until the 45th day after receiving the initial claim to deliver the replacement (or 120 days for heavy-duty vehicles). If you request a refund, the manufacturer must provide it within 30 days of your offer to transfer the vehicle's title.
Remedies and Compensation Under Wisconsin Law
When a vehicle is deemed a lemon, the Wisconsin Lemon Law provides specific remedies to make the consumer whole.
Vehicle Replacement
If you opt for a replacement, the manufacturer must provide a comparable new motor vehicle. While it may not be identical in every detail (e.g., color), it should be of a similar trim level and have comparable options. When accepting a replacement, you must return the lemon vehicle and transfer its title to the manufacturer.
Repurchase and Refund
If you choose a refund, the manufacturer must reimburse you for the full purchase price of the vehicle. This refund must also include:
- Any sales tax paid
- Finance charges
- Amounts paid at the point of sale
- Collateral costs (expenses incurred in connection with the repair, such as alternative transportation)
Mileage Offset Formula: The manufacturer is permitted to deduct a "reasonable allowance for use" from the refund. In Wisconsin, this deduction is calculated using a specific formula: the vehicle's purchase price is multiplied by the number of miles driven before the defect was first reported, and that result is divided by 100,000 (or 20,000 for motorcycles).
Attorney's Fees and Civil Penalties
The Wisconsin Lemon Law includes provisions that allow consumers to recover attorney's fees if they are successful in a lawsuit against the manufacturer. This fee-shifting provision makes it financially feasible for consumers to hire legal representation. Additionally, if a court finds that a manufacturer willfully violated the Lemon Law, it may award the consumer pecuniary loss, costs, disbursements, and reasonable attorney fees.
When to Hire a Wisconsin Lemon Law Attorney
While consumers can navigate the Lemon Law process independently, there are several scenarios where hiring an experienced attorney is highly advisable.
Complexity of Claims and Manufacturer Resistance
Lemon Law claims can become legally complex, especially when manufacturers dispute the severity of the defect or argue that the required number of repair attempts has not been met. Manufacturers have teams of lawyers dedicated to minimizing their liability, and they may employ delay tactics or offer inadequate settlements. An attorney who specializes in Wisconsin Lemon Law understands the nuances of the statute and can effectively counter the manufacturer's arguments, ensuring your rights are protected.
Fee Structure
One of the most significant advantages of hiring a Lemon Law attorney in Wisconsin is the fee structure. Because the statute includes a fee-shifting provision, most Lemon Law attorneys work on a contingency basis. This means that you do not pay out-of-pocket legal fees; the attorney's fees are paid by the manufacturer if you win your case. This arrangement allows consumers to access high-quality legal representation without financial risk.
What to Look for in an Attorney
When seeking legal counsel, look for an attorney with a proven track record of success in handling Wisconsin Lemon Law cases. They should have extensive experience dealing with major auto manufacturers and a deep understanding of state and federal consumer protection laws, including the Magnuson-Moss Warranty Act. A reputable attorney will offer a free initial consultation to evaluate the merits of your case.
Frequently Asked Questions About Wisconsin Lemon Law
Q: Does the Wisconsin Lemon Law cover used cars? A: No, the Wisconsin Lemon Law (Wis. Stat. § 218.0171) specifically applies to new motor vehicles. Used vehicles are not covered under this statute. However, if you purchased a defective used car, you might have legal recourse under the federal Magnuson-Moss Warranty Act or state laws regarding dealer misrepresentation and mandatory safety inspections.
Q: How long do I have to file a Lemon Law claim in Wisconsin? A: You have 36 months from the date the vehicle was delivered to you to file a Lemon Law claim. However, the defect itself must have occurred and been reported during the vehicle's first year of operation and before the manufacturer's express warranty expired.
Q: What happens if the manufacturer's arbitration program is not certified by the state? A: If the manufacturer's arbitration program is not certified by the Wisconsin Department of Transportation, you are not required to participate in it before filing a lawsuit. You can choose to proceed directly to litigation if your claim is denied. If the program is certified, you must go through arbitration first.
Q: Can I get a refund for the accessories I added to my lemon vehicle? A: The Lemon Law requires the manufacturer to refund the full purchase price, which includes amounts paid at the point of sale. If the accessories were installed by the dealer at the time of purchase and included in the purchase contract, they should be part of the refund. Modifications made after the purchase are generally not covered.
Q: Do I have to pay for a Lemon Law attorney? A: In most cases, no. The Wisconsin Lemon Law includes a fee-shifting provision, meaning that if you win your case, the manufacturer is required to pay your reasonable attorney's fees. Most Lemon Law attorneys work on a contingency basis, so you will not have to pay upfront costs.
