Filing a Wisconsin Lemon Law Claim for Defective RVs, Motorhomes, and Travel Trailers

Purchasing a recreational vehicle (RV) is supposed to be the gateway to freedom, allowing you to explore the beautiful state parks of Wisconsin and beyond. However, discovering that your expensive new motorhome or travel trailer is riddled with defects can turn your dream vacation into a stressful nightmare. Leaking roofs, slide-outs that get stuck, or engines that stall on the highway are unfortunately common in the RV industry. The legal rules for returning a defective RV in Wisconsin are significantly more complicated than returning a standard passenger car.

RV manufacturers are notorious for pointing fingers at each other, leaving the consumer trapped in the middle of a warranty dispute. Because the laws treat different types of campers very differently, pursuing a claim requires strategic legal knowledge.

The Dual-Warranty System: Chassis vs. Living Quarters

The most confusing aspect of buying a self-propelled motorhome (Class A, B, or C) is understanding how it is built. A motorhome is essentially two entirely different products bolted together. First, there is the chassis and engine, typically built by a major automotive manufacturer like Ford, Mercedes-Benz, or Freightliner. Second, there is the coach or living quarters (the walls, bed, kitchen, and slide-outs), usually built by a specialized RV company like Thor, Winnebago, or Forest River.

Under Wis. Stat. § 218.0171(1)(d), Wisconsin's Lemon Law strictly defines a motor vehicle to include self-propelled motorhomes, without any statutory exclusion for coach living quarters. Unlike states that limit Lemon Law coverage strictly to the chassis, Wisconsin law protects motorhome buyers against warranty defects in both the chassis and the coach living area. This means you can pursue state Lemon Law remedies whether the defect involves engine overheating or coach failures like severe slide-out malfunctions and plumbing leaks. Indeed, in Nancy Stough v. Newmar Corp., 295 Wis. 2d 842 (WI Court of Appeals 2006), an RV manufacturer was held liable under the Wisconsin Lemon Law for slide-out water intrusion defects in the living quarters, applying the substantial impairment standards recognized in cases like Dieter v. Chrysler Corp., 234 Wis. 2d 670 (WI Supreme Court 2000).

Towable Travel Trailers and the Magnuson-Moss Act

If you purchased a towable travel trailer or a fifth-wheel, the situation changes again. Under Wis. Stat. § 218.0171(1)(d), trailers and semitrailers are explicitly excluded from the definition of a motor vehicle. Because towable campers do not have engines and are not self-propelled, they do not qualify as motor vehicles under Wisconsin's Lemon Law. However, this does not mean you are out of luck.

For defects in towable travel trailers (as well as standalone component warranties on third-party appliances), your attorney will typically file a claim under the federal Magnuson-Moss Warranty Act (15 U.S.C. § 2301). Often referred to as the federal Lemon Law, this act protects consumers when any manufacturer fails to honor their written warranty after a reasonable number of repair attempts. It allows you to sue the RV manufacturer for a refund, replacement, or cash compensation for the diminished value of the camper.

The 30-Day Out of Service Rule

For your motorhome covered by the Wisconsin Lemon Law, you must prove the manufacturer failed to fix the defect. The law states you qualify if the vehicle has been subject to repair four times for the same defect, or if it has been out of service for a cumulative total of 30 days due to warranty repairs during the first year.

In the RV world, waiting 30 days for a repair is incredibly common due to massive delays in shipping specialized parts to local dealerships. Every single day your motorhome sits on the lot at a repair facility waiting for a part counts toward that 30-day limit. If you reach this threshold, you can file Form MV2691, Wisconsin, Department of Transportation, Motor Vehicle Lemon Law Notice with the Wisconsin Department of Transportation, Madison and the chassis manufacturer to demand a resolution.

Taking Legal Action in Wisconsin

If the manufacturers refuse to honor your claim, your attorney can file a civil lawsuit. For state Lemon Law or federal Magnuson-Moss claims, lawsuits are typically filed in the county where the vehicle was purchased, such as the Dane County Circuit Court, Madison or the Brown County Circuit Court, Green Bay. Having a lawyer coordinate the claims against both the chassis manufacturer and the coach builder simultaneously is the most effective way to force a settlement.
