Statute of Limitations for Montana Lemon Law Claims
Timing rules for Montana vehicle claims — the 2-year/18,000-mile warranty period (and the mileage trap), the in-state arbitration, and the CPA and Magnuson-Moss clocks.
Montana’s lemon law is built around its warranty period — 2 years or 18,000 miles, whichever is earlier (§ 61-4-501(7)). The defect and repair history must accrue within that window, and in a high-mileage state the 18,000-mile cap usually controls.
The clocks
| Statute | Period | Runs from |
|---|---|---|
| Lemon Law warranty period | 2 years or 18,000 miles, whichever earlier | Original delivery |
| Arbitration | Held in Montana; arbitration de novo if IDS nonconforming | After notice / IDS |
| Montana CPA | Montana general limitations | Accrual |
| Magnuson-Moss | 4 years (UCC § 30-2-725) | Tender of delivery |
The 18,000-mile trap
Montana’s lemon law doesn’t fix a separate filing deadline so much as a window: the presumption and the defect history must arise during the 2-year / 18,000-mile warranty period. The mileage cap is the catch — Montana has some of the longest average driving distances in the country, so a rural commuter or rancher can pass 18,000 miles in well under two years. If you have a recurring defect, build the record and give written notice before the odometer closes the window.
In-state arbitration
Montana requires arbitration to take place in Montana at a place reasonably convenient to the consumer (§ 61-4-515). If the manufacturer has a certified IDS, the consumer resorts to it first (§ 61-4-507); a nonconforming IDS decision opens arbitration de novo (§ 61-4-520). See state arbitration board.
Build the claim within the warranty period
- Satisfy the presumption (4 attempts or 30 business days) before 2 years / 18,000 miles.
- Give written notice to the manufacturer (§ 61-4-502(3)).
- Pursue arbitration (certified IDS or the Department of Justice program).
When the CPA and Magnuson-Moss matter
The Montana CPA runs on Montana’s general civil limitations, and Magnuson-Moss 4 years from delivery (UCC § 30-2-725) — both can outlast the lemon-law warranty window and are useful fallbacks, especially since they (not the lemon law) carry attorney fees.
Bottom line
Satisfy the presumption and give written notice within the 2-year / 18,000-mile warranty period — and watch the mileage cap, which closes fast in a high-mileage state. The CPA and Magnuson-Moss (4 years) are the longer-running fallbacks and the fee engines.
