Indiana Lemon Law Guide: Your Rights Under Indiana Lemon Law
What Is the Indiana Lemon Law?
The Indiana Lemon Law, officially known as the Motor Vehicle Protection Act (Indiana Code § 24-5-13), is a consumer protection statute designed to help vehicle buyers and lessees who end up with a defective vehicle. If you purchase or lease a vehicle in Indiana that suffers from persistent, unrepairable defects, this law provides a legal pathway to obtain a replacement vehicle or a full refund.
The primary purpose of the Motor Vehicle Protection Act is to ensure that manufacturers stand behind their warranties. When a vehicle fails to meet basic standards of reliability and safety, and the manufacturer or its authorized dealers cannot fix the problem after a reasonable number of attempts, the consumer is protected from being stuck with a "lemon."
The Indiana Attorney General's Consumer Protection Division oversees consumer rights in the state and provides resources for individuals dealing with deceptive business practices, including issues related to defective vehicles. Consumers can file complaints and seek guidance through the Attorney General's office.
Which Vehicles Qualify Under the Motor Vehicle Protection Act?
To be protected under the Indiana Lemon Law, a vehicle must meet specific criteria regarding its type, weight, and the timeframe in which the defects occur.
New vs. Used Vehicle Coverage
Unlike many states that restrict lemon law protections exclusively to brand-new vehicles, Indiana's Motor Vehicle Protection Act applies to all motor vehicles sold, leased, transferred, or replaced by a dealer or manufacturer in Indiana. This means that used cars are covered under the Indiana Lemon Law, provided that the vehicle is still within the "term of protection" and the manufacturer's original warranty is still in effect.
Leased Vehicle Coverage
The Indiana Lemon Law explicitly covers leased vehicles. If you lease a vehicle in Indiana and it turns out to be a lemon, you have the same rights to a refund or replacement as someone who purchased their vehicle outright.
Mileage and Time Limitations
The "term of protection" under Indiana Code § 24-5-13-7 is strictly defined. The protection period begins on the date of the original delivery of the motor vehicle to the buyer. It ends at the earlier of two milestones:
- Eighteen (18) months after the date of original delivery.
- The time the motor vehicle has been driven 18,000 miles after the date of original delivery.
Any defect or nonconformity must be reported to the manufacturer or its authorized dealer within this 18-month or 18,000-mile window to qualify for a claim.
Vehicle Types Covered
The law covers self-propelled vehicles with a declared gross vehicle weight of less than 10,000 pounds that are intended primarily for use on public highways and are required to be registered or licensed.
However, the statute explicitly excludes several types of vehicles, including:
- Conversion vans
- Motor homes and RVs
- Farm tractors and agricultural machinery
- Road building equipment
- Truck tractors and road tractors
- Motorcycles and motor-driven cycles
- Snowmobiles
- Vehicles designed primarily for off-road use
What Qualifies as a "Lemon" in Indiana?
Not every car with a mechanical issue is considered a lemon. Under Indiana Code § 24-5-13-6, a vehicle must have a "nonconformity," which is defined as any specific or generic defect or condition that substantially impairs the use, market value, or safety of the motor vehicle, or renders it nonconforming to the terms of an applicable manufacturer's warranty.
The "Presumption" Threshold: Number of Repair Attempts
Indiana law establishes a presumption that a reasonable number of repair attempts has been undertaken if the manufacturer or its authorized dealers cannot fix the nonconformity after a specific number of tries. According to Indiana Code § 24-5-13-15, a vehicle is presumed to be a lemon if the nonconformity has been subject to repair at least four (4) times, but the defect continues to exist.
Days Out of Service Threshold
Alternatively, a vehicle can qualify as a lemon if it is out of service by reason of repair for any nonconformity for a cumulative total of at least thirty (30) business days, and the nonconformity continues to exist. This 30-day period can be extended if repair services are unavailable due to events like strikes, natural disasters, or acts of war, provided the dealer offers a free rental vehicle during the delay.
Substantial Impairment Standard
The defect must be significant. Minor annoyances, such as a rattling speaker or a small cosmetic flaw, typically do not qualify. The defect must substantially impair the vehicle's use, market value, or safety.
The Indiana Lemon Law Claims Process
Navigating a lemon law claim requires strict adherence to statutory procedures and timelines.
Required Steps and Manufacturer Notification
Before you can demand a refund or replacement, you must give the manufacturer or its authorized dealer a reasonable opportunity to repair the vehicle. If the vehicle meets the threshold of four repair attempts or 30 business days out of service, you must notify the manufacturer in writing of the ongoing nonconformity and your demand for a refund or replacement.
Documentation Requirements
Success in a lemon law claim relies heavily on documentation. You should keep meticulous records of:
- The original purchase or lease agreement.
- All repair orders and invoices, ensuring they accurately describe the problem, the dates the vehicle was in the shop, and the work performed.
- All correspondence with the dealer and the manufacturer.
Arbitration Requirements
Before filing a lawsuit, Indiana consumers may be required to participate in an informal dispute settlement procedure (arbitration) if the manufacturer has established a program that complies with federal regulations (such as the Magnuson-Moss Warranty Act) and state law. Programs like BBB AUTO LINE are commonly used. If the arbitration decision is unsatisfactory, the consumer retains the right to pursue a civil lawsuit.
Timeline Expectations
Lemon law claims can take several months to resolve, depending on whether the manufacturer agrees to a settlement, whether arbitration is required, and whether litigation becomes necessary.
Remedies and Compensation Under Indiana Law
If your vehicle is determined to be a lemon, the Motor Vehicle Protection Act provides specific remedies. The choice between a refund and a replacement vehicle generally belongs to the consumer.
Vehicle Replacement
If you choose a replacement, the manufacturer must provide a comparable motor vehicle of equal or greater value.
Repurchase and Refund
If you opt for a refund, Indiana Code § 24-5-13-11 dictates that the manufacturer must refund the full contract price of the vehicle, including all credits and allowances for any trade-in vehicle, less a reasonable allowance for use.
Mileage Offset Formula: The reasonable allowance for use (mileage deduction) is calculated using a specific statutory formula: (Total Contract Price) × (Miles driven before the manufacturer's acceptance of return ÷ 100,000)
Incidental Damages
In addition to the vehicle's purchase price, the refund must include reimbursement for incidental costs, such as:
- All sales tax.
- The unexpended portion of the registration fee and excise tax.
- All finance charges actually expended.
- The cost of all options added by the authorized dealer.
- Towing and rental car costs incurred due to the nonconformity.
Attorney's Fees and Civil Penalties
If a consumer prevails in a civil lawsuit under the Indiana Lemon Law, the court may award reasonable attorney's fees and costs. This fee-shifting provision makes it possible for consumers to hire legal representation without paying out of pocket. Furthermore, if a court finds that a manufacturer willfully violated the law, it may award damages up to three times the amount of actual damages.
When to Hire an Indiana Lemon Law Attorney
While consumers can pursue claims on their own or through arbitration, hiring an experienced Indiana lemon law attorney is highly recommended.
Complexity of Claims
Lemon law cases involve strict statutory deadlines, complex mileage offset calculations, and detailed evidentiary requirements. An attorney understands how to navigate the Motor Vehicle Protection Act and the federal Magnuson-Moss Warranty Act to maximize your compensation.
Manufacturer Resistance Patterns
Automakers have teams of lawyers dedicated to minimizing payouts and denying lemon law claims. They may argue that the defect does not substantially impair the vehicle, that the issue was caused by consumer abuse, or that the repair attempts were not properly documented. An attorney can counter these tactics effectively.
Fee Structure
Most lemon law attorneys work on a contingency basis or rely on the fee-shifting provisions of the law. This means they only get paid if you win your case, and their fees are typically paid by the manufacturer, not deducted from your settlement.
What to Look for in an Attorney
When seeking legal representation, look for an attorney who specializes in consumer protection and auto defect litigation in Indiana. They should have a proven track record of taking cases to trial if necessary and a deep understanding of state and federal warranty laws.
Frequently Asked Questions About Indiana Lemon Law
Does the Indiana Lemon Law apply to used cars?
Yes, the Indiana Motor Vehicle Protection Act applies to used cars, provided the vehicle is still within the statutory term of protection (18 months or 18,000 miles from the date of original delivery to the first buyer) and the manufacturer's warranty is still active.
How many repair attempts are required in Indiana?
A vehicle is presumed to be a lemon if it has been subject to repair for the same defect at least four (4) times, or if it has been out of service for a cumulative total of at least thirty (30) business days.
Are motorcycles or RVs covered under the Indiana Lemon Law?
No. The Indiana Lemon Law explicitly excludes motorcycles, motor-driven cycles, motor homes, conversion vans, and off-road vehicles.
What is the mileage offset deduction?
If you receive a refund, the manufacturer is allowed to deduct a "reasonable allowance for use." In Indiana, this is calculated by multiplying the vehicle's purchase price by the number of miles driven before the return, divided by 100,000.
Do I have to go through arbitration?
If the manufacturer has a certified informal dispute settlement program, you generally must participate in it before filing a lawsuit. However, the arbitrator's decision is not legally binding on you, and you can still sue if you are unhappy with the outcome.
Will I have to pay out of pocket for a lemon law attorney?
Typically, no. The Indiana Lemon Law includes a fee-shifting provision, meaning that if you win your case, the manufacturer is required to pay your reasonable attorney's fees and court costs. Most lemon law lawyers will evaluate and take your case without charging upfront fees.
