How to File a Lemon Law Claim in Montana

Montana-themed title graphic for a guide on filing a Lemon Law claim, featuring the Montana state flag and RockPoint Law branding.

To file a Montana lemon law claim, confirm your new vehicle qualifies, document every repair attempt for the same defect, notify the manufacturer in writing, then submit your claim through the manufacturer's certified dispute program or the Montana Department of Justice arbitration forum. The law applies when a new or leased vehicle still has a substantial defect after a reasonable number of repair attempts, at which point the manufacturer must replace it or buy it back. Drivers who qualify can pursue a replacement vehicle, a manufacturer buyback, or a refund of the purchase price plus collateral charges.

What Is Montana Lemon Law?

With more than 900,000 registered vehicles on Montana roads, warranty disputes involving new cars, trucks, SUVs, and motorcycles affect a significant number of consumers across the state, according to the Montana Department of Justice, Motor Vehicle Division. Montana's lemon law is formally the New Motor Vehicle Warranty Act, codified at Mont. Code Ann. §§ 61-4-501 through 61-4-533. It protects people who buy or lease a new vehicle with a defect the manufacturer can't fix after a fair chance.

The Montana Department of Justice Office of Consumer Protection administers the New Motor Vehicle Warranty Act and runs the state arbitration forum where many of these disputes are settled. They also handle thousands of consumer complaints annually, making warranty and vehicle-related disputes a routine part of the state's consumer-protection work.

A vehicle becomes a lemon under § 61-4-503 when a defect substantially impairs its use, market value, or safety and persists after a reasonable number of repair attempts during the warranty period. The defect has to be covered by the express warranty, and ordinary wear, owner abuse, or unauthorized modifications don't count.

The statute puts the repair obligation on the manufacturer, not the dealer. Under § 61-4-502, once you notify the manufacturer in writing of a nonconformity during the warranty period, the required repairs must be made at the warrantor's expense even if the warranty later expires. Manufacturers must also disclose in the warranty that written notice is required before you're eligible for a refund or replacement.

Montana drivers also have backstops beyond the lemon law: the federal Magnuson-Moss Warranty Act lets a prevailing consumer recover attorney fees in many warranty cases, and the Montana Consumer Protection Act covers deceptive sales practices. For a borderline situation, a Montana lemon law attorney can tell you which path fits.

Does Your Vehicle Qualify Under Montana Lemon Law?

Montana's law covers new motor vehicles purchased, titled, or leased in the state, including motorcycles, and leased vehicles get the same protection as purchased ones. What it does not cover is used cars because Montana has no used-car lemon law, so a vehicle bought secondhand falls outside this statute, though a Magnuson-Moss or Consumer Protection Act claim may still apply.

To stay inside the protected window, the vehicle must be less than two years old and have 18,000 miles or fewer, whichever limit it hits first, measured from the date of original delivery. Some vehicles are excluded outright: those used primarily for business, trucks over 15,000 pounds gross vehicle weight, off-road and non-motorized vehicles, and the living quarters of a motorhome.

Leased vehicles deserve a note. Lease a new car in Montana that develops a qualifying defect, and you have the same right to a buyback or replacement as a buyer, though the refund and offset math works differently for a lease, one reason lease cases are worth running past an attorney.

The defect is the heart of any claim. It must substantially impair the vehicle's use, market value, or safety. These defects can include a recurring engine fault, a transmission that keeps failing, brakes that won't hold, and persistent stalling. A loose trim piece or a minor rattle won't meet the substantial-impairment standard the statute requires.

Montana Lemon Law Eligibility Requirements

The central requirement is a reasonable number of repair attempts. Under § 61-4-504, that's presumed when the same defect has been repaired four or more times during the warranty period and still isn't fixed. The Office of Consumer Protection advises sending certified written notice after the third unsuccessful attempt, giving the manufacturer a final chance on record.

There's a separate route based on downtime. The standard is also presumed met if the vehicle has been out of service because of the defect for a cumulative total of 30 or more business days during the warranty period, after you've notified the manufacturer or dealer. Those are business days, not calendar days, and the count is cumulative across visits, not 30 in a row.

Timing rounds it out. The defect must arise, and your written notice must reach the manufacturer, during the two-year/18,000-mile warranty window. Problems that surface only afterward, defects from accidents, neglect, or aftermarket changes, and cosmetic issues that don't impair use, value, or safety generally don't qualify. Because Montana's deadlines turn on the warranty period, acting early protects your claim.

How to File a Lemon Law Claim in Montana

Filing a lemon law claim in Montana is a process that depends on good documentation and following the required steps in order. From reporting the defect to giving the manufacturer a reasonable opportunity to make repairs, each stage helps strengthen your claim and protects your rights. Each step builds the record the next depends on. Here's how to move through the process from start to finish.

Step 1: Determine Whether Your Vehicle Qualifies

Confirm the vehicle is new or leased, inside the two-year/18,000-mile window, and that the defect substantially impairs its use, value, or safety.

Step 2: Gather Repair and Warranty Records

Collect your purchase or lease agreement, the warranty booklet, and every repair order tied to the defect.

Step 3: Track Repair Attempts and Vehicle Downtime

Log each visit for the same defect and the business days out of service---you're building toward the four-attempt or 30-business-day presumption.

Step 4: Document All Communications With the Dealer and Manufacturer

Save emails, texts, service notes, and call records so nothing turns into a "we were never told" dispute.

Step 5: Notify the Manufacturer of the Defect

Send written notice by certified mail, return receipt requested---a step the statute requires before you're eligible for a refund or replacement.

Step 6: Allow Additional Repair Opportunities if Required

After notice, give the manufacturer its final chance to fix the defect and document the result.

Step 7: Prepare Your Claim Documentation

Organize the agreements, repair orders, downtime log, and notice letter into one clean package that tells the story start to finish.

Step 8: Submit Your Montana Lemon Law Claim

File through the manufacturer's certified dispute program if one exists; if not, bring the dispute to the Montana DOJ arbitration forum. The state requires you to use a certified manufacturer program first when one is available.

Step 9: Pursue Settlement, Buyback, Replacement, or Legal Remedies

If that doesn't resolve it fairly, a lemon law attorney can press for a buyback, replacement, or settlement and litigate under warranty law.

Montana Lemon Law Documents Checklist

Filing a lemon law claim in Montana is a process that depends on good documentation and following the required steps in order. From reporting the defect to giving the manufacturer a reasonable opportunity to make repairs, each stage helps strengthen your claim and protects your rights. Each step builds the record the next depends on. Here's how to move through the process from start to finish.

  1. Purchase or Lease Agreement: Proves you bought or leased the vehicle new in Montana and fixes the original delivery date.
  2. Registration and Title Records: Confirm ownership and that the vehicle was titled in the state.
  3. Warranty Documentation: Shows the express warranty terms and that the defect is covered.
  4. Repair Orders: Each one documents a separate repair attempt for the same defect.
  5. Service Invoices: Itemize the work and dates, backing up your attempt count.
  6. Vehicle Repair Records: The full service history ties every visit together in sequence.
  7. Service and Maintenance Records: Show you kept up routine maintenance, closing off a common manufacturer defense.
  8. Communications With the Dealer and Manufacturer: Emails, letters, and notes that show what was reported and when.
  9. Proof of Vehicle Downtime: Loaner paperwork or dated service tickets establishing the cumulative business days out of service.
  10. Claim Filing Documents: Your written notice and any arbitration or program submission forms.

What Are the Manufacturer Notification Requirements in Montana?

Notify the manufacturer in writing while the vehicle is still inside the warranty period, not after it expires. Under § 61-4-502, that written notification keeps the repair obligation alive and makes you eligible for a refund or replacement, and the Office of Consumer Protection recommends doing it after the third unsuccessful repair.

The notice should identify the vehicle by VIN, describe the defect, summarize the repair history with dates, and state that you're invoking your rights under Montana's New Motor Vehicle Warranty Act. Precision here makes it harder for a manufacturer to claim it didn't understand the problem.

Send the notice to the manufacturer or its authorized agent, the entity that issued the express warranty, not just the selling dealer. The warranty booklet usually lists the correct address.

Delivery method matters for proof. Use certified mail, return receipt requested, and keep the letter and green card with your claim file. That receipt often becomes key evidence later.

What Remedies Are Available Under Montana Lemon Law?

The primary remedy is a manufacturer buyback. Under § 61-4-503, when a qualifying defect can't be fixed after a reasonable number of attempts, the manufacturer must replace the vehicle or, alternatively, take it back and refund the full purchase price less a reasonable allowance for your use. That choice between replacement and refund rests with the manufacturer, not the consumer.

A replacement vehicle has to be the same model and style and of equal value, or, if that exact vehicle isn't available, one of comparable market value. For many drivers, that's the simplest outcome.

A refund isn't just the sticker price. The statute requires the full purchase price plus reasonable collateral charges and incidental damages, paid to you and any lienholder in proportion to your interests. The manufacturer does get to subtract a reasonable allowance for your use, and Montana sets that by a fixed formula under § 61-4-501: the total contract price multiplied by the miles you drove before the vehicle's return, divided by 100,000. In plain terms, a car with more miles on it carries a bigger deduction, one more reason acting early protects the value of your claim.

Incidental costs are recoverable too. Costs such as towing, rental, and similar out-of-pocket expenses tied to the defect are often recoverable. If your matter moves to arbitration, § 61-4-519 lets the arbitrator award expenses and costs to the prevailing party, and federal warranty law often allows a prevailing consumer to recover attorney fees, which is why RockPoint clients typically pay nothing out of pocket.

What Are the Common Mistakes That Can Hurt a Montana Lemon Law Claim?

Waiting too long is the big one. If you let the two-year/18,000-mile window close before reporting the defect in writing, you can lose the protection entirely, so report issues the first time they appear.

Thin records are the second. Verbal complaints and missing repair orders make it nearly impossible to prove the four-attempt or 30-business-day threshold. Get a written repair order every visit, even when the dealer says it couldn't replicate the issue.

Skipping the written notice trips up otherwise solid claims. Calling the dealer isn't enough. The statute requires written notice to the manufacturer, with certified mail as proof. A missing notice or disorganized records hands manufacturers an easy defense.

Finally, don't assume one denial is the end. Manufacturers routinely reject first requests, and drivers who stop there leave buybacks and replacements on the table when arbitration or an attorney could have changed the result.

Montana Lemon Law Examples

These examples are illustrative, not actual RockPoint cases or clients, and only show how the law tends to apply.

Consider a new SUV bought in Bozeman that starts stalling at highway speed within the first year. The owner brings it in four times; the dealer reflashes software, swaps sensors, and replaces a fuel component, but the stalling returns. Because the same safety-related defect survived four repair attempts inside the warranty period, the reasonable-attempts presumption is met and a buyback claim becomes realistic.

Transmission defects follow a similar pattern. Picture a new truck in Great Falls that shudders and slips between gears, spending well past 30 cumulative business days at the dealership while the problem persists.

Here the downtime route can apply even before a fourth repair, because the vehicle has been out of service long enough to trigger the presumption. A driver in that spot might call RockPoint Law for a free consultation, send over the repair orders and downtime records, and let the team handle the manufacturer notice and claim, pursuing the buyback, replacement, or settlement the firm is built around, with no fee unless it wins. Past results never guarantee a similar outcome.

What Is the Montana Lemon Law Timeline?

Understanding the Montana lemon law timeline helps you know what to expect after discovering a serious vehicle defect. While every case is different, most claims follow a similar path, from reporting the problem and documenting repair attempts to requesting a refund or replacement if the issue cannot be fixed. Most Montana lemon law claims move through a recognizable sequence, mapped below from each stage to its typical action. The timeline below outlines each step and what typically happens next.

Ready to Speak With a Montana Lemon Law Attorney About Your Claim?

The pattern is consistent: confirm your new or leased vehicle is inside the two-year/18,000-mile window, document every repair attempt and day out of service, notify the manufacturer in writing by certified mail, and pursue the buyback, replacement, or refund you're owed.

You don't have to manage that against an automaker's lawyers alone, and waiting rarely helps. "Most people don't realize how much the written record decides their case," says Aaron Waldo, a lemon law attorney at RockPoint Law. "Every repair order and every day out of service is leverage and we put it in the right order and make the manufacturer answer for it." A short conversation can tell you whether you qualify and what your claim is worth.
