Lemon Law

What It Means

Lemon laws are state-level consumer protection statutes that provide remedies to buyers of new (and in some states, used) motor vehicles that repeatedly fail to meet reasonable standards of quality and performance despite multiple manufacturer or dealer repair attempts. All 50 states and the District of Columbia have lemon laws, but the specific thresholds vary widely. The most common standard, modeled on California's Song-Beverly Consumer Warranty Act, requires the manufacturer to replace or refund when a substantial defect cannot be repaired after four repair attempts for the same defect, or after the vehicle has been out of service for at least 30 cumulative days within the first 18 months or 18,000 miles of ownership (whichever comes first). Several states extend to 24 months or 24,000 miles, and a few (Washington, New Jersey) apply to used vehicles as well. Lemon laws are distinct from federal warranty protections under the Magnuson-Moss Warranty Act (1975), which creates federal remedies but does not impose state-style repurchase triggers. Lemon laws are also distinct from NHTSA recall authority, because they address vehicle-specific failures (one car is a lemon even if the rest of the production run is fine), whereas recalls address fleet-wide defects. Lemon law cases are handled through state consumer protection agencies or state court, often with attorney fee-shifting provisions that allow plaintiffs to recover legal fees from manufacturers. Manufacturers that repurchase vehicles under lemon law must report those buybacks through title branding requirements in most states, so "lemon law buyback" appears in Carfax and AutoCheck reports, a critical signal for used-vehicle buyers because a repurchased vehicle may have been resold through dealer auctions with only limited disclosure to the next buyer. RecallCheck focuses on NHTSA data and does not directly track lemon law buybacks.

Lemon Law is one of the NHTSA or vehicle-safety concepts that recurs across RecallIndex. The definition above is the technical answer; below is how the concept connects to the NHTSA data that drives every vehicle page on the site.

In the RecallIndex Safety Score, this concept feeds one of the four factor weights — recall severity (40 percent), complaint frequency (30 percent), crash and fire reports (20 percent), or trend direction (10 percent). The methodology page on the site walks through every input in detail.
