Kentucky Repair-Attempt Presumption (4 attempts / 30 days OOS)

Ky. Rev. Stat. § 367.842 — standard 4-attempt threshold within the 12-month / 12K Rights Period, OR 30 cumulative calendar days OOS. Written notice to manufacturer is a procedural prerequisite.

Kentucky applies the “reasonable number of attempts” presumption under Ky. Rev. Stat. § 367.842 when the manufacturer has failed to repair a nonconformity. KY uses the standard 4-attempt threshold — same tier as the majority of state lemon laws — with a written-notice-to-manufacturer prerequisite before the refund/replacement obligation attaches.

The two presumption pathways

A consumer establishes the “reasonable number of attempts” presumption under § 367.842 by showing either:

Pathway 1 — Four attempts

  • The same nonconforming condition has been subject to four or more repair attempts by the manufacturer or its agents; AND
  • Within the 12-month / 12,000-mile Rights Period.

Pathway 2 — 30 cumulative OOS days

  • The motor vehicle is out of service due to repair attempts; AND
  • For a cumulative total of 30 or more calendar days within the Rights Period.

Where KY’s 4-attempt threshold fits

KY joins the standard 4-attempt tier:

Less consumer-favorable than 3-attempt jurisdictions:

Distinct from Alabama’s “3 + final manufacturer attempt” structure (which effectively requires 4 attempts but with a separate manufacturer-level final attempt after written notice). KY’s 4 attempts are at the dealer/manufacturer level without a separate procedural step.

The 30-day OOS pathway in detail

The 30-day pathway under § 367.842 is often the faster route to the presumption:

  • Cumulative count — not consecutive. Vehicle in for 10 days in January, 12 days in March, 9 days in June meets threshold at 31 cumulative days.
  • Calendar days — NOT business days (more conservative than the 30-business-day jurisdictions: Colorado, Massachusetts, Indiana, Missouri, Oregon, North Carolina (20-business-day)).
  • Within the Rights Period — must occur within the 12-month / 12K window.
  • In custody for repair — counts time the vehicle is at the dealer/manufacturer awaiting or undergoing repair.

The written-notice prerequisite — distinctive

§ 367.842 requires the buyer to report the nonconformity in writing to the manufacturer before the refund/replacement obligation attaches. This is distinctive among peer states:

  • Most peer states require implicit notice through repair attempts at authorized dealers — written notice not separately required.
  • KY makes the written notice a specific procedural prerequisite — skip it and the manufacturer has a defense.

Best practice for the written notice:

  • Send by certified mail with return receipt requested.
  • Include:
    • Consumer name and contact information.
    • Vehicle VIN, year, make, model.
    • Date of delivery and current mileage.
    • Description of the persistent nonconformity.
    • List of prior repair attempts (dates, dealer, RO numbers).
    • Demand for refund or replacement under § 367.842.
  • Keep the certified-mail receipt AND return-receipt card as evidence of compliance.

Documentation requirements

To establish either pathway, the consumer needs:

  • Repair orders for each attempt — dates, mileage, customer complaint, technician notes, parts replaced.
  • Consistent complaint language — same words describing the same nonconformity across visits.
  • Days-out-of-service log documenting cumulative count for the 30-day pathway.
  • Photographs/video of the recurring defect when possible.
  • Communications with dealer service writers and manufacturer customer relations.
  • Written notice to the manufacturer (with certified-mail receipts).

Bottom line

KY’s standard 4-attempt or 30-day OOS presumption under § 367.842 is consistent with most peer states. The 30-day calendar-day counting is more conservative than business-day jurisdictions. The written-notice-to-manufacturer requirement is a procedural prerequisite that distinguishes KY from many peer states — skip it and the manufacturer’s refund/replacement obligation doesn’t attach. Combined with KY’s 12-month / 12K Rights Period and 2-year action SOL, the presumption framework requires fast, disciplined documentation and notice strategy.
