Montana’s Lemon Law may help if your new vehicle has a serious problem that the manufacturer cannot fix. The problem must affect the vehicle’s safety, use, or value, and it must be covered by the warranty.
In general, the law applies if the problem happens within two years after delivery or before the vehicle reaches 18,000 miles.
Keep copies of all repair orders, note how many days the vehicle is in the shop, and notify the manufacturer in writing.
If your vehicle qualifies, you may be entitled to a replacement vehicle or a refund. Eligibility depends on the repair history, deadlines, and your documentation.

Do You Qualify for Montana Lemon Law?
Do You Qualify for Montana Lemon Law?
You may qualify for protection under Montana’s Lemon Law if you bought or leased a new vehicle with a serious problem that’s covered by the manufacturer’s warranty.
The problem must continue even after the dealer or manufacturer has had a reasonable number of chances to fix it.
A serious defect is one that affects the vehicle’s safety, use, or value. Examples may include repeated brake problems, electrical issues, engine trouble, or defects that significantly reduce fuel economy.
Keep detailed records of every problem, repair visit, invoice, and conversation with the dealer or manufacturer. Report issues as soon as possible and request repairs while the vehicle is still under warranty.
Do not accept a claim that the issue is “normal maintenance” unless the dealer provides a clear written explanation. Good records can help protect your rights if the problem can’t be fixed.
Vehicles Covered Under Montana Lemon Law
Montana’s Lemon Law may protect you if you buy or lease a new vehicle that has serious defects and meets the law’s requirements. Before you file a claim, make sure your vehicle is covered. Coverage can depend on the type of vehicle and how it’s used.
Some vehicles may not qualify, including certain recreational vehicles, off-road vehicles, commercial vehicles, and used vehicles.
Eligible New Motor Vehicles
Montana’s lemon law may cover new vehicles sold or leased in Montana if they come with a manufacturer’s written warranty. This can include cars, trucks, vans, motorcycles, and some recreational vehicles.
Your vehicle may qualify if:
- You bought or leased it new in Montana.
- It has a written manufacturer’s warranty.
- You mainly use it for personal, family, or household transportation.
- You reported warranty problems quickly and kept records of repair visits.
Keep copies of your purchase or lease paperwork, warranty booklet, repair orders, and important dates. These documents can help show whether your vehicle is covered.
Excluded Vehicle Categories
Not every new vehicle is covered by Montana’s lemon law, even if it has a manufacturer warranty. Before asking for a buyback or replacement, make sure your vehicle qualifies.
The law generally does not cover vehicles made mainly for off-road use or certain large commercial vehicles. If your vehicle is not covered, you may still have rights under the manufacturer’s warranty, a service contract, or other consumer-protection laws.
| Vehicle type | Usually covered? | What to do next |
|---|---|---|
| Passenger car | Yes | Keep records of every problem and repair visit. |
| Pickup truck under the legal weight limit | Yes | Ask the dealer to repair the problem and save all paperwork. |
| Motorcycle | No | Review your warranty and any service contract. |
| Off-road vehicle | No | Check for other legal or warranty options. |
Keep copies of repair orders, warranty documents, letters, emails, and other communications with the dealer or manufacturer.
Defects That Support a Lemon Law Claim
Defects That May Support a Montana Lemon Law Claim
A vehicle problem may support a Montana lemon law claim if it seriously affects the vehicle’s safety, value, or ability to be used normally, and the manufacturer or an authorized dealer can’t fix it after a reasonable number of repair attempts.
Keep records of the symptoms, repair visits, invoices, and how the problem affects your daily driving. Problems that may qualify include:
- Safety problems, such as brake, steering, airbag, or electrical failures.
- Reliability problems, such as engine, transmission, or starting issues that make the vehicle hard to depend on.
- Value-related problems, such as water leaks, ongoing warning lights, or structural defects that lower the vehicle’s value.
- Repeated problems that keep coming back and interfere with normal driving or use of the vehicle.
Routine maintenance issues and unrelated financial concerns usually don’t qualify. The key question is whether the defect has a serious effect on your vehicle and whether it has been reasonably repaired.
Montana Lemon Law Repair Attempt Rules
To qualify under Montana’s lemon law, you usually must give the manufacturer or an authorized dealer a fair chance to fix the same problem.
Report the issue as soon as possible. Explain the problem the same way each time, and keep copies of every repair order, invoice, text, email, and diagnostic report.
If you take the vehicle in several times for the same problem and it still isn’t fixed, that may support your claim—even if the dealer gives different reasons for the problem each visit.
Make sure the repair paperwork clearly states your complaint and what work the dealer performed. Don’t accept vague descriptions if they don’t accurately explain the issue.
Good records can help show that the dealer had repeated chances to repair the defect but didn’t fix it.
The 30-Day Out-of-Service Rule
Keep track of every day your vehicle is in the shop for warranty repairs, including repeat visits for the same problem.
If your vehicle is out of service for 30 total days, you may have rights under Montana’s Lemon Law.
Save all repair orders, service records, and receipts to help support your claim.
Calculating Out-of-Service Days
Montana’s 30-day out-of-service rule may support a lemon law claim if warranty repairs keep your vehicle unavailable for a total of 30 or more business days. Add up all the business days the dealer has your vehicle for covered repairs, even if the repairs happen over several separate visits.
- Keep every repair order. Make sure it shows the date you dropped off the vehicle and the date you picked it up.
- Count business days only. Don’t count weekends or legal holidays.
- Count days the vehicle is waiting for parts if the dealer keeps the vehicle during that time.
- Compare your total with service invoices, repair records, and your calendar.
Good records can help show how long your vehicle was actually unavailable and reduce disagreements about the repair timeline.
Rights After Thirty Days
If your vehicle has been in the shop for warranty repairs for 30 or more business days, you may have rights under Montana’s lemon law. You don’t have to keep waiting while the same problem leaves you without your vehicle.
Keep records of every repair visit, including dates, repair orders, rental car costs, and messages with the dealer or manufacturer. The 30 days can be added together from separate repair visits—it doesn’t have to be one long stay in the shop.
You may need to notify the manufacturer in writing and give them one final chance to fix the problem. Depending on the situation, you may be able to request a replacement vehicle, a refund, or other relief.
Document Every Montana Lemon Law Repair
Why does documentation matter under the Montana Lemon Law? Your records show what went wrong, what the dealer tried to fix, and whether the problem was actually repaired. Good records can help protect your rights and support your side of the story.
- Keep every repair order, invoice, and diagnostic report.
- Make sure each document includes your complaint, the vehicle’s mileage, the date, and the work performed.
- Save emails, text messages, appointment confirmations, and other communications with the dealer.
- Take photos or videos of warning lights, leaks, damage, and recurring problems when they happen.
If a repair order leaves out your complaint or describes the problem incorrectly, ask the dealer to correct it right away.
Montana Lemon Law Deadlines to Know
Deadlines matter in a Montana Lemon Law claim. If your vehicle keeps going back for the same problem, don’t wait too long to act.
Montana Lemon Law protections generally apply during the first two years after delivery or before the vehicle reaches 18,000 miles, whichever happens first. Keep careful records of every repair visit, the mileage on each date, and the number of days your vehicle is out of service.
You may also have a limited time to take legal action after the coverage period ends. Check the current deadline as soon as possible. Review your warranty, save all repair paperwork, and consider speaking with a lawyer before your filing deadline passes.
Notify the Manufacturer About the Defect
Meeting Montana’s deadlines is important, but you should also notify the vehicle manufacturer in writing about the defect. Written notice shows that you gave the manufacturer a chance to address the problem and helps create a record of what happened.
Notify the manufacturer in writing to document the defect and give them an opportunity to address the problem.
In your notice, include:
- Your vehicle’s year, make, model, and VIN.
- A clear description of the defect and when it occurred.
- The dates of any repair visits and what repairs were attempted.
- Any ongoing safety issues or problems using the vehicle.
- A request for written confirmation that the manufacturer received your notice.
Keep copies of the letter, delivery confirmation, repair records, and any messages you receive from the manufacturer. Stick to the facts and focus on the vehicle problem.
How to Start a Montana Lemon Law Claim
To start a Montana Lemon Law claim, collect all records related to your vehicle and its repairs. Keep copies of your purchase or lease agreement, warranty, repair orders, and any messages with the dealer or manufacturer.
Make a simple timeline showing:
- Each problem you reported
- The dates the vehicle was taken in for repairs
- What repairs were attempted
- Whether the problem continued after repair
- How many days the vehicle was unavailable because of repairs
You should also send written notice to the manufacturer if required and keep proof that it was delivered. Clear, organized records can help show that the vehicle has a warranty-covered defect that was not fixed after reasonable repair attempts.
| Document | Why You Need It | What To Do |
|---|---|---|
| Purchase or lease agreement | Shows when you obtained the vehicle | Keep a complete copy |
| Warranty documents | Shows what defects may be covered | Save all warranty paperwork |
| Repair orders and invoices | Shows the defect, repair attempts, and repair dates | Request complete copies from the dealer |
| Messages with dealer or manufacturer | Shows what you reported and how they responded | Save emails, letters, and texts |
| Written notice and delivery proof | Shows the manufacturer received your notice | Keep the letter and delivery receipt |
Submit accurate copies promptly, but keep the originals in your own files.
Montana Lemon Law Arbitration Options
You may be able to use the vehicle manufacturer’s arbitration program before going to court. Check whether the program’s decision is binding or nonbinding. A binding decision may limit your ability to take further legal action.
For the hearing, gather your repair records, warranty documents, emails or letters with the manufacturer or dealer, and proof showing how the problem affects your vehicle’s use, value, or safety.
Manufacturer-Sponsored Arbitration Programs
Manufacturer-sponsored arbitration programs may offer a faster, free way to resolve a Montana lemon law dispute if your vehicle’s manufacturer participates.
You can submit repair records, warranty papers, and other proof showing that the problem continued after reasonable repair attempts. Keep your case focused on the vehicle defect and how it affects the vehicle’s use, value, or safety.
- Check whether the manufacturer offers an arbitration program for your vehicle.
- Collect repair invoices, service dates, mileage records, warranty documents, and messages with the dealer or manufacturer.
- Prepare a simple timeline showing the recurring problem and each repair attempt.
- Attend the hearing prepared. Clearly explain the problem, its impact on the vehicle, and why the repairs didn’t fix it. Keep copies of everything you submit.
Asking about or using an arbitration program doesn’t mean you give up your consumer rights.
Binding Versus Nonbinding Decisions
Whether an arbitration decision is binding depends on the program’s rules and any agreement you sign. In Montana, read the warranty, arbitration clause, and program materials before you participate.
A nonbinding decision usually means you can reject the result and still pursue other options, including going to court.
A binding decision may limit your right to sue, so make sure you understand the deadlines, appeal rights, and exceptions before you agree to the process.
Do not let the manufacturer dismiss these terms as unimportant or unrelated. They can directly affect your bargaining power, available remedies, and right to seek a refund, replacement, or damages under the law.
Ask for the terms in writing and keep copies.
Preparing For Arbitration Hearings
Once you know whether the arbitration decision will be binding, prepare as though you may need to prove every part of your Montana lemon law claim.
Gather evidence showing the problem with the vehicle, its repair history, and the manufacturer’s chances to fix it. Stay focused on the vehicle defect and avoid unrelated issues.
- Bring repair orders, invoices, warranty documents, and emails or letters with the dealer or manufacturer.
- Make a timeline showing when the problem started, each repair visit, and how many days the vehicle was out of service.
- Take photos or videos of the problem when it happens, if it’s safe to do so.
- Practice a short, clear explanation of how the defect affects the vehicle’s use, value, or safety.
Ask for copies of the manufacturer’s documents before the hearing. Point out any errors or missing information, and ask the arbitrator to consider all relevant evidence.
Refunds and Replacements for Lemon Vehicles
If your vehicle qualifies as a lemon under Montana law, you can ask the manufacturer for either a replacement vehicle or a refund. You can choose the option that best fits your situation, as long as you meet the legal requirements.
If your vehicle qualifies as a lemon in Montana, you may choose a replacement vehicle or a refund from the manufacturer.
A replacement vehicle should be very similar to the one you bought and include the same options and warranty coverage.
A refund usually includes the purchase price, taxes, registration fees, and other covered costs. The manufacturer may subtract a reasonable amount for the time you used the vehicle before the first repair attempt.
Review any refund offer carefully. Keep copies of your purchase documents, repair records, and receipts. If the manufacturer leaves out costs you believe should be included, you can challenge the calculation.
Loans, Leases, and Trade-Ins After a Claim
A lemon-law refund or replacement can affect your car loan, lease, or trade-in. Make sure you handle these responsibilities as part of your claim.
- Ask your lender for the exact payoff amount and confirm whether your payments are current.
- If you lease the vehicle, review your lease agreement for mileage limits, fees, and early-termination terms.
- Collect trade-in records that show the vehicle’s value, loan balance, and any credits you received.
- Keep your insurance active until you’re officially no longer responsible for the vehicle.
If you receive a refund, the money may be used first to pay off your remaining loan balance. If you receive a replacement vehicle, you may need to complete new financing paperwork. Don’t assume the dealer will automatically close your loan or lease account.
Get written confirmation of every payoff, credit, title transfer, and account closure. Track important deadlines and make sure your records match the final outcome of your claim.
When to Contact a Montana Lemon Law Attorney
Contact a Montana lemon law attorney if the manufacturer denies your claim, keeps delaying repairs, offers an unfair settlement, or you’re close to a legal deadline. You don’t have to accept unclear answers, repeated failed repairs, or pressure to trade in a defective vehicle.
A lawyer can review your repair records, warranty, emails, texts, and other documents to see whether you may qualify for a refund, replacement vehicle, or other compensation. Get legal advice before signing a release or settlement agreement, since it may limit your rights.
Keep records of the vehicle’s problems, repair visits, time without your vehicle, and related costs. Acting quickly can help protect your claim and preserve important deadlines.
Frequently Asked Questions
Does Montana Lemon Law Cover Used Vehicles?
Generally, Montana’s Lemon Law does not cover used vehicles. It mainly applies to new vehicles that come with a manufacturer’s warranty.
If you bought a used vehicle, you may still have options if the seller gave you a warranty, made false statements about the vehicle, or violated the terms of your contract. Review your purchase paperwork, keep records of repairs and communications, and ask the seller in writing to address the problem.
Are Motorcycles Protected Under Montana Lemon Law?
Motorcycles are generally not covered by Montana’s lemon law. The law mainly applies to new cars and light trucks, so motorcycle owners may not have the same legal protections or warranty remedies. Used vehicle coverage is also limited.
Can I Recover Attorney’s Fees in a Lemon Law Case?
If you win your lemon law case, the manufacturer may have to pay your attorney’s fees and court costs. However, there can be limits on how much you can recover. Keep records of all expenses and talk with a lemon law attorney about your options.
Does Montana Lemon Law Apply to Vehicles Bought Out of State?
Yes—Montana’s Lemon Law may apply to a new vehicle bought in another state if you register it in Montana. For example, a new truck purchased in Idaho could be covered once it is registered here.
Used vehicles usually are not covered unless they still have an applicable manufacturer’s warranty.
Can a Business-Owned Vehicle Qualify for Lemon Law Protection?
Yes. A business-owned vehicle may qualify for Lemon Law protection if it meets the legal requirements. However, vehicles used as part of a fleet may be excluded.
To determine whether your vehicle qualifies, consider why it was purchased, whether it is covered by a warranty, its repair history, and its weight.
Conclusion
You may be wondering whether Montana’s Lemon Law can help if your vehicle has serious, repeated problems. It can—if your vehicle qualifies and the defect affects its use, value, or safety.
Keep records of every repair visit, invoice, and day your vehicle is out of service. Do not assume repeated repairs are normal or that you have to live with an unreliable vehicle. Deadlines may apply, so it is important to act quickly.
A Montana Lemon Law attorney can review your situation and help you seek a refund or replacement vehicle.
