Indiana's Repair-Attempt Presumption (4 Attempts / 30 Business Days OOS)

How Ind. Code § 24-5-13-15 establishes 'reasonable number of attempts' — 4-attempt or 30-business-day OOS thresholds within the 18-month / 18,000-mile Rights Period.

Under Indiana Lemon Law (§ 24-5-13-15), the manufacturer has had a “reasonable number of attempts” to repair when statutory thresholds are met. Once met, the burden shifts to the manufacturer to prove the vehicle is not a lemon.

The two thresholds

Either threshold satisfies the presumption:

  1. Four or more repair attempts for the same nonconformity within the Rights Period; OR
  2. 30 or more cumulative business days out of service for any nonconformity.

Both apply within the 18-month / 18,000-mile Rights Period.

The 4-attempt rule

§ 24-5-13-15 sets a 4-attempt presumption. Each “attempt” must be:

  • At a manufacturer-authorized service facility.
  • Documented in a repair order.
  • For the same nonconformity (consistent complaint language).
  • Within the 18-month / 18,000-mile Rights Period.

The 30-business-day OOS rule

§ 24-5-13-15 provides for 30 or more cumulative business days out of service. Indiana’s business-day counting joins:

Business-day counting is more consumer-favorable than calendar-day jurisdictions (CT, GA, VA, CA, NJ, NY, TX, WA, OH, IL, PA, WI, TN at 30 calendar days).

30 business days = approximately 42 calendar days (excluding weekends).

Written notice requirement

§ 24-5-13-12 requires the consumer to give the manufacturer written notice of the defect and at least one final opportunity to repair before the Lemon Law applies. The notice should:

  • Identify the nonconformity.
  • Reference the prior repair attempts.
  • Demand a final repair opportunity.
  • Be sent via certified mail (return receipt requested).

Indiana sits in the middle on attempts (4) but is consumer-favorable on OOS counting (business days). No single-attempt safety exception.

Bottom line

Indiana requires 4 attempts or 30 business days OOS within the 18-month / 18,000-mile Rights Period plus written notice of a final repair opportunity. The business-day OOS counting is consumer-favorable.
