Hawaii Lemon Law

Hawaii’s lemon law — formally the Motor Vehicle Express Warranty Enforcement Act, HRS § 481I — is among the most consumer-favorable in the country. Disputes resolve through a fast, low-cost state-administered arbitration program (SCAP) run by the Department of Commerce and Consumer Affairs (DCCA); the remedy is a refund or replacement (the manufacturer elects between them under § 481I-3(b)); and the presumption thresholds are low. Layered on top is Hawaii’s powerful UDAP (HRS § 480-13), which gives a prevailing consumer automatic treble damages (or a $1,000 floor) plus mandatory attorney fees.

Hawaii is distinctive in five ways:

1. State-run SCAP arbitration. Under § 481I-4, the DCCA administers the State Certified Arbitration Program — a decision comes within 45 days, the manufacturer pays a $200 filing fee and the consumer just $50 (refunded if they win). It’s consumer-initiated and not a mandatory hurdle to court. See state arbitration board.
2. An automatic-treble UDAP with mandatory fees. HRS § 480-13 awards a prevailing consumer $1,000 or treble damages, whichever is greater — automatically — plus mandatory fees, with a $5,000 elder enhancement. This joins the automatic-treble tier with North Carolina and New Jersey.
3. Low presumption thresholds. The presumption needs only 3 attempts, 1 for a serious safety defect, or 30 business days out of service — among the easier triggers in the country. (The remedy itself, refund or replacement, is manufacturer-elected under § 481I-3(b).)
4. Motorcycles covered. HRS § 481I-2 covers motorcycles (per HRS 286-2) — unlike Arizona or Idaho. Mopeds, scooters, and vehicles over 10,000 lbs GVWR are excluded.
5. The island parts-delay factor. Because most parts ship from the mainland, vehicles sit out of service longer — making the 30-business-day threshold realistically easy to reach. Salt air and VOG also drive distinctive corrosion and electrical failures.

Who’s protected

The Hawaii Lemon Law (§ 481I-2) covers a self-propelled vehicle used primarily for personal, family, or household purposes — including motorcycles (per HRS 286-2), demonstrators, and individually registered business vehicles.

Excluded: mopeds and motor scooters, and vehicles over 10,000 lbs GVWR. For those, the UDAP and Magnuson-Moss remain available.

The presumption: 3 attempts, 1 for safety, or 30 business days

Under § 481I-3, within the Rights Period (2 yr / 24,000 mi, whichever earlier):

• 3 or more repair attempts for the same nonconformity; OR
• 1 attempt for a defect likely to cause death or serious bodily injury; OR
• 30 or more cumulative business days out of service.

Plus a written report of the nonconformity to the manufacturer during the Rights Period. See the repair-attempt presumption guide.

What you can recover

A successful Hawaii claim typically produces:

• Refund (consumer’s election) — full purchase price plus undercoating, dealer prep, transportation, options, and collateral/incidental charges, minus a 1%-per-1,000-mile use offset; or replacement.
• SCAP resolution within 45 days, with discretionary arbitration fees.
• UDAP § 480-13 — automatic treble or the $1,000 floor, plus mandatory fees, with the $5,000 elder enhancement.
• Magnuson-Moss § 2310(d)(2) fees.

Hawaii’s island environment

• Salt air / marine corrosion — coastal humidity and salt accelerate electrical, brake, and body corrosion (no road salt, but salt air is the driver).
• VOG (volcanic smog) on Hawai’i Island — sulfur dioxide can affect air-intake and corrosion.
• Mainland parts delays — lengthen the out-of-service count.
• Tropical heat / intense UV — stress EV batteries, paint, rubber, and interiors.
• Markets: Oahu/Honolulu (dominant), Maui, Hawai’i Island (Hilo/Kona), Kauai — with limited franchised-dealer networks per island.

What to do next

1. Report the defect in writing to the manufacturer during the Rights Period. See our evidence guide.
2. Document every repair attempt and day out of service — parts delays count.
3. Elect SCAP arbitration for a fast, low-cost decision — or go to court.
4. File within 1 year of the Rights Period’s end.
5. Pursue UDAP § 480-13 in court for automatic treble and mandatory fees.
6. Get a free case review from a Hawaii lemon-law attorney.
