Hawaii's Repair-Attempt Presumption (3 Attempts / 1 for Safety / 30 Business Days)

Hawaii’s presumption thresholds are among the most consumer-favorable in the country: just 3 attempts for an ordinary defect, 1 attempt for a serious safety defect, or 30 business days out of service — all under HRS § 481I-3. The island context makes the out-of-service threshold especially easy to reach.

The three thresholds

Test	Threshold
Same nonconformity, repair attempts	3 or more (and the defect persists)
Nonconformity likely to cause death or serious bodily injury	1 attempt (and it persists)
Cumulative business days out of service	30 or more

Any one threshold, met within the Rights Period (express-warranty term or 2 years / 24,000 miles, whichever earlier), raises the presumption.

The 3-attempt and 1-attempt-safety standards

Hawaii’s 3-attempt ordinary-defect threshold is more consumer-favorable than the 4-attempt norm of Arizona and Idaho. The 1-attempt serious-safety-defect rule covers any defect likely to cause death or serious injury — broader than Idaho’s braking/steering-only rule — joining Georgia, Virginia, and West Virginia.

The island parts-delay angle

The 30-business-day out-of-service threshold is unusually easy to reach in Hawaii. Because most replacement parts ship from the mainland, a vehicle can sit out of service for weeks awaiting parts — running up the cumulative-day count faster than on the mainland. Track every day the vehicle is in the shop (or waiting on parts the dealer has taken it in for); these delays work in the consumer’s favor on the OOS threshold.

The written-notice requirement

The presumption applies only if the consumer reported the nonconformity in writing to the manufacturer (or its agent/distributor/dealer) during the Rights Period, and the manufacturer had a reasonable opportunity to repair (§ 481I-3(a)). Distinctively, the dealer must notify the manufacturer upon a second notice of the nonconformity, or once the vehicle has been out of service more than 20 business days.

What counts as a repair attempt

• Vehicle was at the manufacturer’s agent or an authorized dealer, documented by a repair order.
• The same nonconformity persists.
• “No problem found” visits count if the defect was reported.
• Independent-mechanic visits and routine maintenance don’t count.

The presumption is rebuttable

Meeting a threshold creates a presumption, not an automatic win — the manufacturer can argue the defect doesn’t substantially impair use or value, or resulted from abuse or unauthorized modification. Clean documentation defeats these.

Bottom line

Three attempts, one for a serious safety defect, or 30 business days out of service — within the Rights Period, with a written report to the manufacturer — raises Hawaii’s presumption. The island’s mainland parts-shipping delays make the 30-day OOS threshold a realistic path; document every day out of service carefully.
