Procedural Details in Missouri

Missouri's lemon law (R.S.Mo. Section 407.560 et seq.) covers new motor vehicles and applies when the same defect cannot be repaired after four repair attempts, or the vehicle is out of service for 30 or more cumulative days — within one year or 12,000 miles of original delivery. Missouri requires informal dispute settlement before filing a lawsuit if the manufacturer has such a program. Missouri's Merchandising Practices Act is notable: it prohibits any "deception, fraud, false pretense, misrepresentation" in connection with any sale — a broad definition that Missouri courts have applied expansively. Private actions under the MPA allow actual damages, punitive damages, and attorney fees. Insurance bad faith in Missouri is addressed under common law and the MPA. The statute of limitations for MPA claims is five years. The Missouri Department of Commerce and Insurance handles insurer complaints.

Frequently Asked Questions

What triggers Missouri's lemon law?

Missouri lemon law applies after four repair attempts for the same defect or 30 cumulative days out of service — within one year or 12,000 miles. The manufacturer's informal dispute resolution must be exhausted before filing suit. Keeping complete written documentation of every repair visit is essential.

Why is Missouri's Merchandising Practices Act considered broad?

Missouri courts have interpreted the MPA expansively to cover virtually any deceptive or misleading conduct in connection with a sale — even if unintentional. This broad definition makes it one of the most plaintiff-favorable consumer fraud statutes. Private actions allow actual damages, punitive damages, and attorney fees with a five-year SOL.

Are punitive damages available for consumer fraud in Missouri?

Yes. Missouri's MPA allows courts to award punitive damages for intentional or reckless deceptive conduct. This is in addition to actual damages and attorney fees. The five-year statute of limitations is longer than many states, providing more time to identify and pursue fraud claims.

How does Missouri handle insurance bad faith?

Missouri recognizes first-party bad faith claims under common law and through the Merchandising Practices Act when insurer conduct is deceptive. If an insurer unreasonably denies or delays a valid claim, you may have grounds for both regulatory complaint and private litigation. The Missouri Department of Commerce and Insurance handles consumer complaints against insurers.
