The Law: Montana Lemon Law and the Consumer Protection Act

Montana’s lemon law — the New Motor Vehicle Warranty Act, Mont. Code Ann. § 61-4-501 to -533 — delivers a refund or replacement through arbitration held in Montana. Because the lemon law has no fee provision of its own, the Consumer Protection Act (§ 30-14-133) and federal Magnuson-Moss carry the attorney fees and multiplier.

The three pillars

1. Montana New Motor Vehicle Warranty Act — § 61-4-501 to -533. A 4-attempt / 30-business-day presumption; a 2-year / 18,000-mile warranty period; a manufacturer-elected refund or replacement; and arbitration (certified IDS or Department of Justice program) that must take place in Montana.
2. Montana Consumer Protection Act (CPA) — § 30-14-101 et seq., private action under § 30-14-133. Actual damages, discretionary treble (up to 3x, no dollar cap), and discretionary attorney fees (capped at $250/hour; no fees if the consumer recovers $100,000 or more). A lemon-law violation is a per se CPA violation (§ 61-4-533).
3. Federal Magnuson-Moss Warranty Act — 15 U.S.C. § 2301 et seq. Civil court; § 2310(d)(2) attorney fees; federal-court access (D. Mont.).

Montana pairs a manufacturer-elected lemon-law remedy with a CPA that supplies the discretionary multiplier and fees.

Topics in this section

• Montana Lemon Law statute (§ 61-4-501) — Eligibility, the 2-year/18,000-mile period, the presumption, the manufacturer-elected remedy, and the 100,000-mile offset.
• Montana Consumer Protection Act (§ 30-14-133) — Discretionary treble, discretionary fees, the caps, and the per se lemon-law violation.
• Magnuson-Moss Warranty Act — Federal overlay and fee hook.
• Repair-attempt presumption — The 4-attempt and 30-business-day thresholds and the written-notice prerequisite.
• Statute of limitations — The 18,000-mile trap, the warranty period, and the CPA and Magnuson-Moss clocks.

Why three statutes instead of one

The Warranty Act delivers refund or replacement through Montana arbitration. The CPA adds:

• Actual damages for a deceptive practice.
• Discretionary treble damages (up to 3x, no dollar cap; the $100,000 limit applies to attorney fees).
• Discretionary attorney fees — the lemon law’s only realistic fee path (via § 61-4-533).

Magnuson-Moss adds federal-court access (D. Mont.), § 2310(d)(2) fees, and a 4-year runway — an important fee engine given the lemon law’s silence and the CPA’s discretionary, capped fees.

How they interact procedurally

1. Give written notice to the manufacturer (§ 61-4-502(3)) and document repair attempts (4 attempts or 30 business days).
2. Arbitration in Montana — a manufacturer’s certified IDS (a prerequisite to its protections, § 61-4-507) or the Department of Justice program (§ 61-4-515); arbitration de novo if an IDS is nonconforming (§ 61-4-520).
3. Civil action — Montana court, pairing the Warranty Act with the CPA and Magnuson-Moss for fees.
