Vehicles and the Lemon Law
Montana’s
New Motor Vehicle Warranty Act
helps consumers who have bought a new vehicle that qualifies as a “lemon.” When repeated attempts at repair have been unsuccessful, the law may require the manufacturer to replace or repair the defective vehicle.
The Lemon Law covers
Vehicles purchased, titled or leased in Montana, provided they are less than two years old and have 18,000 miles or less on the odometer. This includes motorcycles.
Substantial defects that impair the use, market value or safety of the vehicle
The Lemon Law does not cover
Vehicles purchased for business use
Trucks over 15,000 lbs. GVW
Non-motorized and off-road vehicles
The “residential” portion of motor homes
Defects resulting from accident, abuse, neglect, modification or alteration by anyone other than the manufacturer or authorized dealer
Warranty Period
The warranty period ends two years after the date of the vehicle’s original delivery to the consumer, or the first 18,000 miles of operation, whichever occurs first. This period can be extended for up to a year if a defect is reported,Â
in writing
, to the dealer or manufacturer during the warranty period but has not been cured by the expiration of the period.
Required Documentation
Keep all records of warranty repairs and all written communications with dealers and manufacturers. Work orders provide the best proof as to when a problem was first reported.
To prove that a vehicle is a lemon, be prepared to produce:
All purchase (or lease) documents
All maintenance records
All repair orders
Receipt for maintenance supplies
Certified letter of notification to the manufacturer (copy)
Any and all other documents relating to the defect
Lemon Law Process
Notify the manufacturer. If the problem is a substantial defect or condition that recurs or still exists after the third repair attempt, notify the manufacturer by certified mail, return receipt requested, of the need to repair the defect or condition on the fourth attempt. This notification procedure is not required under the Lemon Law, but does serve as notice to the manufacturer of your intentions.
If the manufacturer fails to correct any substantial defect or condition following your written notification, the manufacturer must either refund the full purchase price – plus any reasonable expenses directly incurred because of the vehicle’s condition – or provide an identical or reasonably similar replacement vehicle. If the vehicle is bought back, the manufacturer can deduct an amount for the use of the vehicle calculated based on the odometer reading at the time of repurchase.
If you think you are entitled to a refund or replacement and the manufacturer is unwilling to provide either remedy, you must first submit your dispute to a state-certified dispute settlement program approved by the Montana Department of Justice. Contact the Office of Consumer Protection for further assistance.

## Vehicles and the Lemon Law
Montana’s [New Motor Vehicle Warranty Act](http://leg.mt.gov/bills/mca/title_0610/chapter_0040/part_0050/sections_index.html) helps consumers who have bought a new vehicle that qualifies as a “lemon.” When repeated attempts at repair have been unsuccessful, the law may require the manufacturer to replace or repair the defective vehicle.
## The Lemon Law covers
- Vehicles purchased, titled or leased in Montana, provided they are less than two years old and have 18,000 miles or less on the odometer. This includes motorcycles.
- Substantial defects that impair the use, market value or safety of the vehicle
## The Lemon Law does not cover
- Vehicles purchased for business use
- Trucks over 15,000 lbs. GVW
- Non-motorized and off-road vehicles
- The “residential” portion of motor homes
- Defects resulting from accident, abuse, neglect, modification or alteration by anyone other than the manufacturer or authorized dealer
## Warranty Period
The warranty period ends two years after the date of the vehicle’s original delivery to the consumer, or the first 18,000 miles of operation, whichever occurs first. This period can be extended for up to a year if a defect is reported, **in writing**, to the dealer or manufacturer during the warranty period but has not been cured by the expiration of the period.
## Required Documentation
Keep all records of warranty repairs and all written communications with dealers and manufacturers. Work orders provide the best proof as to when a problem was first reported.
To prove that a vehicle is a lemon, be prepared to produce:
- All purchase (or lease) documents
- All maintenance records
- All repair orders
- Receipt for maintenance supplies
- Certified letter of notification to the manufacturer (copy)
- Any and all other documents relating to the defect
## Lemon Law Process
1. Notify the manufacturer. If the problem is a substantial defect or condition that recurs or still exists after the third repair attempt, notify the manufacturer by certified mail, return receipt requested, of the need to repair the defect or condition on the fourth attempt. This notification procedure is not required under the Lemon Law, but does serve as notice to the manufacturer of your intentions.
2. If the manufacturer fails to correct any substantial defect or condition following your written notification, the manufacturer must either refund the full purchase price – plus any reasonable expenses directly incurred because of the vehicle’s condition – or provide an identical or reasonably similar replacement vehicle. If the vehicle is bought back, the manufacturer can deduct an amount for the use of the vehicle calculated based on the odometer reading at the time of repurchase.
3. If you think you are entitled to a refund or replacement and the manufacturer is unwilling to provide either remedy, you must first submit your dispute to a state-certified dispute settlement program approved by the Montana Department of Justice.
