Which Repair Shop Should I Use for a Montana Lemon Law Claim?

Why you must use an authorized dealer for repairs to count toward Montana's lemon-law presumption — and how the 18,000-mile cap and long distances interact.

For repairs to count toward Montana’s lemon-law presumption, you must use the manufacturer or an authorized dealer — not an independent shop.

Why the authorized dealer matters

The 4-attempt / 30-business-day presumption counts only repairs by the manufacturer or an authorized dealer. Independent-mechanic visits and DIY repairs don’t count — and unauthorized modifications can trigger an abuse defense.

Best practices

  • Use an authorized franchised dealer for every warranty repair.
  • Get a repair order at each visit describing the nonconformity in your words.
  • Log your mileage at each visit — the warranty period ends at 18,000 miles, which Montana drivers reach quickly.
  • Give written notice to the manufacturer (§ 61-4-502(3)).
  • Report the same nonconformity consistently to preserve the count.
  • Keep all paperwork, including parts-on-order notes — see documenting evidence.

The long-distance reality

Montana is a vast state with few dealers. The nearest authorized dealer can be hours away, and parts can take time to arrive — which lengthens out-of-service days (counting toward the 30-business-day threshold) but also means you should plan visits carefully against the 18,000-mile clock.

Tesla and direct-service brands

For Tesla and similar direct-service manufacturers, the manufacturer’s own service is the “authorized” channel — rural owners may travel far or wait on mobile service.

Bottom line

Always use the manufacturer’s authorized dealer so repairs count, log your mileage against the 18,000-mile cap, give written notice, and keep every repair order. Get a free case review.
