How Long Do I Have to File a Montana Lemon Law Claim?
Montana's deadlines — the 2-year/18,000-mile warranty period (and the mileage trap), in-state arbitration, and the CPA and Magnuson-Moss clocks.
Montana’s lemon law is built around the warranty period — 2 years or 18,000 miles, whichever is earlier. In a high-mileage state, the 18,000-mile cap usually controls. See the full statute of limitations guide.
The clocks
| Claim | Period | Runs from |
|---|---|---|
| Lemon Law warranty period | 2 years or 18,000 miles, whichever earlier | Original delivery |
| Arbitration | Held in Montana; de novo if IDS nonconforming | After notice / IDS |
| Montana CPA | Montana general limitations | Accrual |
| Magnuson-Moss | 4 years | Tender of delivery |
The 18,000-mile trap
The defect history and presumption must arise within the 2-year / 18,000-mile warranty period — and because Montana has some of the longest driving distances in the country, a rural commuter or rancher can pass 18,000 miles in well under two years. Build the record and give written notice before the odometer closes the window.
In-state arbitration
Arbitration must be held in Montana (§ 61-4-515) — a certified IDS or the Department of Justice program, with arbitration de novo if an IDS was nonconforming (§ 61-4-520).
When the CPA and Magnuson-Moss matter
The Montana CPA runs on Montana’s general limitations, and Magnuson-Moss 4 years from delivery — both can outlast the lemon-law warranty window and (importantly) carry the attorney fees the lemon law lacks.
Bottom line
Build the lemon-law record and give written notice within the 2-year / 18,000-mile warranty period — and watch the mileage cap, which closes fast. The CPA and Magnuson-Moss (4 years) are the longer fallbacks and the fee engines. Get a free case review.
