Indiana Lemon Law

A plain-English guide to Indiana's Lemon Law (Ind. Code § 24-5-13), the Indiana Deceptive Consumer Sales Act (IDCSA), and the path to refund or replacement.

Indiana’s lemon law — codified at Ind. Code § 24-5-13 (“Indiana Motor Vehicle Protection Act”) — pairs an 18-month / 18,000-mile Rights Period with a 4-attempt or 30-business-day OOS threshold. Layered on top is the Indiana Deceptive Consumer Sales Act (IDCSA) under Ind. Code § 24-5-0.5 et seq., which provides treble damages and mandatory attorney fees for uncured deceptive acts. The IDCSA’s distinctive pre-suit cure notice requirement under § 24-5-0.5-5(a)(2) gives manufacturers 30 days to cure before treble damages attach — a procedural step that must be followed precisely.

Indiana is distinctive in five ways:

  1. 18-month / 18,000-mile Rights Period — a distinctive combination sitting between Virginia’s 18-month with no mileage cap and 2-year states. Tighter than most major states.
  2. IDCSA pre-suit cure notice requirement under § 24-5-0.5-5(a)(2) — 30 days for “incurable” deceptive acts to be cured before treble damages attach. Procedural step unique to Indiana’s UDAP.
  3. IDCSA treble damages or $500 minimum under § 24-5-0.5-4(a) — discretionary treble damages OR $500 statutory minimum, whichever greater. Plus mandatory § 24-5-0.5-4(d) attorney fees.
  4. FIVE home-state OEM manufacturing operations — more than any other US state:
    • Toyota Princeton (Highlander, Sequoia, Sienna, Grand Highlander)
    • Subaru of Indiana Automotive (SIA) Lafayette (Outback, Legacy, Impreza, Ascent)
    • GM Fort Wayne (Silverado HD, Sierra HD)
    • Honda Greensburg (Civic, CR-V)
    • Elkhart County RV manufacturing hub — Thor HQ, Forest River, Jayco, Keystone, Heartland, Coachmen, Newmar, etc. — roughly 80% of US RV production.
  5. 2-year IDCSA SOL under § 24-5-0.5-5(b) — moderate; longer than Tennessee’s 1-year TCPA but shorter than 6-year UDAPs like Pennsylvania UTPCPL and Minnesota Private AG Statute.

Who’s protected

Indiana’s Lemon Law (Ind. Code § 24-5-13-1) covers:

  • New motor vehicles purchased or leased in Indiana for personal, family, or household use.
  • Demonstrators sold under new-vehicle warranties.
  • Subsequent transferees during the Rights Period.

The statute excludes vehicles purchased for commercial use only, motor homes (except chassis), and vehicles weighing more than 10,000 lbs GVWR.

The 18-month / 18,000-mile Rights Period

Indiana’s eligibility window under § 24-5-13-7 is 18 months from original delivery OR 18,000 miles OR end of express warranty, whichever first. This 18/18K combination sits between:

Outside the 18/18K window, IDCSA (2-year SOL) and Magnuson-Moss (4-year UCC SOL) remain available.

The “reasonable number of attempts” test

Indiana applies thresholds under § 24-5-13-15:

  • Four or more repair attempts for the same nonconformity within the Rights Period; OR
  • 30 or more cumulative business days out of service.

See our repair-attempt presumption article.

IDCSA cure notice — distinctive

Under § 24-5-0.5-5(a)(2), before filing a treble-damages IDCSA suit for an “incurable deceptive act,” the consumer must give the supplier written notice and a 30-day opportunity to cure. If the supplier cures, no treble damages. If the supplier does not cure (or refuses), treble damages attach plus mandatory fees.

This is a procedural step unique to Indiana and must be followed precisely — failure to give pre-suit cure notice can defeat treble damage exposure.

Manufacturer IDS — BBB Auto Line

Under § 24-5-13-19, if the manufacturer maintains a certified IDS procedure (16 C.F.R. Part 703 compliant), the consumer must first use that procedure. Most major manufacturers’ IDS in Indiana is BBB Auto Line.

After IDS, the consumer may file court action — Indiana does NOT have a separate state-administered Lemon Law arbitration board.

What you can recover

What to do next

  1. Document everything. See our evidence guide.

  3. Identify the 4th repair attempt (or 30 cumulative OOS business days).
  4. Send written notice with final repair opportunity under § 24-5-13-12.
  5. For IDCSA treble damages: Send separate IDCSA cure notice under § 24-5-0.5-5(a)(2) giving 30-day cure window.
  6. Use manufacturer’s IDS (BBB Auto Line) if certified — required first.
  7. File court action with parallel IDCSA + Magnuson-Moss claims.
