Indiana lemon law protection can force a manufacturer to refund or replace a qualifying defective vehicle. You must report the defect during the protection period. That period ends after 18 months or 18,000 miles, whichever comes first.
A vehicle may qualify when a covered defect remains after four repair attempts. It may also qualify after 30 business days out of service for repairs. Eligible buyers can choose a comparable replacement or refund, subject to statutory rules and any required notice or dispute process.

What the Indiana Lemon Law Covers
Indiana calls this statute the Motor Vehicle Protection Act. It covers qualifying vehicles that an Indiana dealer or manufacturer sells, leases, transfers, or replaces. Buyers must acquire the vehicle for a purpose other than resale or sublease.
A covered motor vehicle generally weighs less than 10,000 pounds. It must be intended mainly for public highways and require registration or licensing. The statute excludes motorcycles, motor homes, conversion vans, snowmobiles, and several commercial or off-road vehicle types.
The protection period starts on the vehicle’s original delivery date. It ends after 18 months or 18,000 miles, whichever happens first. Reporting the defect during that window is critical, even when repairs continue later.
Does a Used Car Qualify?
Indiana does not create a separate used-car protection period starting at each resale. The statutory clock runs from the vehicle’s original delivery date. That timing means many ordinary used vehicles will already be outside the state-law window.
Still, the statute does not exclude every used vehicle. A later dealer transfer may occur while the original protection period remains open. Buyers should verify the original delivery date, mileage history, warranty status, and seller type before assuming coverage.
Private-party sales generally fall outside the chapter’s dealer-or-manufacturer application language. Other warranty or consumer laws may still provide remedies. Lawflowa’s consumer protection lawyer guide can help readers understand broader consumer-rights issues.
What Defects Count as a Nonconformity?
A minor annoyance does not automatically trigger a refund or replacement. Indiana defines a nonconformity as a substantial impairment or a failure to meet an applicable manufacturer warranty. The problem can affect use, market value, safety, or warranty conformity.
Examples can include serious steering, braking, electrical, transmission, or repeated warning-system failures. The facts and repair history matter more than a defect label. A manufacturer can defend a claim by showing abuse, neglect, or unauthorized modification caused the problem.
If a defect caused an injury, other legal theories may also matter. Defective-product claims can involve different proof, damages, and deadlines. Lawflowa’s product liability attorney guide explains those separate claims.
How Many Repair Attempts Are Required?
Indiana treats four repair attempts as a reasonable number when the nonconformity still exists. The attempts must involve the manufacturer, its agent, or an authorized dealer. Detailed repair orders help show what problem was reported and what work occurred.
There is also a 30-business-day route. The vehicle must be out of service for repairs for at least 30 cumulative business days. The nonconformity must still exist after that period. Indiana counts business days, not calendar days. Certain extraordinary events can extend the 30-day period when repair services are unavailable. The manufacturer must show that an allowed event directly caused the delay.
What Should You Do After Repeated Repair Failures?
- Report the defect promptly. Describe the same symptoms consistently and request written repair documentation.
- Use an authorized repair facility. Repairs by the manufacturer, its agent, or authorized dealer support the statutory record.
- Save every document. Keep repair orders, mileage readings, towing receipts, rental receipts, emails, and warranty materials.
- Check notice requirements. Review the warranty or owner’s manual for required written notice to the manufacturer.
- Review dispute procedures. You may need to complete a manufacturer-certified process before filing a lawsuit.
- Calculate deadlines early. Track both the protection period and the separate deadline for filing a civil action.
Do not rely only on what a service adviser says verbally. Ask for a written repair order every time the vehicle is examined. Written records can show dates, mileage, complaints, parts, labor, and whether the same problem continued.
Financing problems can create separate risks while a defect dispute continues. Missed payments may lead to repossession issues even if the warranty dispute remains unresolved. Lawflowa’s car repossession guide covers lender and borrower issues separately.
Manufacturer Notice and Dispute Procedures
Written notice to the manufacturer is required only when the manufacturer made the statutory disclosure. That disclosure should appear clearly in the warranty or owner’s manual. It should also provide the name and address for sending notice.
A manufacturer may also have a certified informal dispute process. Buyers who received adequate written notice may need to use that process first. Skipping a required process can create a procedural problem before litigation begins.
The Indiana Attorney General advises consumers to review warranty instructions and retain repair orders. Its consumer materials also explain complaint options and contact information. Filing a complaint does not replace individualized legal advice from a private attorney.
Refunds, Replacements, and Related Costs
After a reasonable number of failed attempts, the manufacturer must accept the vehicle’s return. The buyer may choose a comparable replacement or qualifying refund. The manufacturer generally has 30 days to provide the selected remedy.
For a purchased vehicle, the refund starts with the full contract price. It includes trade-in credits and certain qualifying charges. The manufacturer then deducts a statutory use allowance based on mileage before accepting the return.
The use allowance multiplies the contract price by miles traveled, then divides by 100,000. The refund can also include specified taxes, prepaid fees, finance charges, and dealer-added options. Necessary towing and rental costs tied to the defect can also be reimbursable.
Replacement vehicles carry separate transfer and sales-tax reimbursement rules. Manufacturer-related financing cannot become less favorable solely because of the replacement. Buyers should compare written replacement terms with the original financing documents before signing.
How Long Do You Have to File a Lawsuit?
A civil action generally must start within two years after the buyer first reports the nonconformity. This deadline differs from the 18-month or 18,000-mile reporting window. The two periods serve different purposes and should both be tracked.
Using a qualifying informal dispute procedure can toll the two-year filing period while that process is underway. Tolling rules can be fact-sensitive in practice. Anyone approaching a deadline should get individualized advice before assuming extra time exists.
A prevailing buyer may recover reasonable costs and attorney’s fees under the statute. That rule can affect the economics of hiring counsel. It does not guarantee a free case or a successful result.
Common Mistakes That Can Weaken a Claim
- Waiting until after 18 months or 18,000 miles to report the defect.
- Leaving the dealership without a written repair order.
- Using inconsistent descriptions for the same recurring problem.
- Ignoring written manufacturer notice requirements in warranty materials.
- Skipping a required certified dispute process.
- Assuming a used vehicle is automatically covered or automatically excluded.
- Missing the separate two-year deadline for a civil action.
Frequently Asked Questions
Does Indiana lemon law coverage apply to used cars?
Sometimes, but the key clock starts at the original delivery rather than resale. A later dealer transfer may still occur within that original window. Most older used vehicles fall outside the state statute because time or mileage has already expired.
Is four repair attempts always required?
No single route controls every qualifying claim. Four attempts can satisfy the repair threshold when the nonconformity continues. Thirty cumulative business days out of service can provide another statutory route.
Can you choose a refund instead of a replacement?
Yes, a qualifying buyer can choose between a comparable replacement and a refund. Refund calculations include a statutory allowance for vehicle use. The exact amount depends on contract figures, mileage, and eligible charges.
Do you have to notify the manufacturer in writing?
Whether you must notify the manufacturer in writing depends on whether the manufacturer made the required statutory disclosure. Check the warranty and owner’s manual for notice instructions and an address. Keep proof of delivery when sending any required notice.
Do you need a lawyer to bring a claim?
The statute does not require every buyer to hire a lawyer. A private attorney can evaluate coverage, notice duties, deadlines, and remedies. The Indiana Attorney General cannot act as a private lawyer for individual consumers.
Next Steps for Indiana Vehicle Owners
Start by organizing the purchase contract, warranty, repair orders, and mileage records. Compare your dates against the protection period and two-year lawsuit deadline. Then check whether the manufacturer requires notice or a certified dispute process.
Consumers can also review the Indiana Attorney General’s Consumer Protection Division guidance and its complaint process. A complaint may help document a consumer issue, but it is not private representation. A qualified attorney should provide legal advice after reviewing the specific facts.
