Hyundai Cases Under Hawaii Lemon Law

Hyundai and Genesis cases in Hawaii — Theta II engine failures/fires, oil consumption, and Ioniq EV defect patterns, with salt-air and heat factors.

Hyundai (including Genesis) has strong Hawaii market share — Elantra, Tucson, Santa Fe, Kona, and Sonata are common. Cases are pursued under the Hawaii Lemon Law, the HRS § 480-13 UDAP, and Magnuson-Moss.

Common Hyundai defect patterns

  • Theta II 2.0T/2.4L engine — bearing failure, seizure, engine fires (extensive recall/class-action history).
  • Nu / Gamma engine oil consumption.
  • Rod-bearing knock and stalling.
  • Dual-clutch (DCT) issues.
  • Ioniq 5 / Ioniq 6 EV — ICCU failure (12V drain/no-start), charging.
  • Theft-vulnerability software issues (Kia/Hyundai immobilizer).

Hawaii Hyundai market

  • Elantra / Tucson / Kona core volume.
  • Santa Fe / Palisade family segment.
  • Growing Ioniq EV presence.

Safety + UDAP leverage

Theta II engine fires are a serious safety matter — one-attempt-rule territory — and the deep recall/class-action history strongly supports a UDAP automatic-treble theory. Salt air aggravates electrical and Ioniq ICCU issues.

Bottom line

Hyundai cases — Theta II engine failures/fires, oil consumption, and Ioniq ICCU — are strongly positioned under Hawaii law, with the engine-fire history supporting UDAP treble. Use SCAP for speed or court for treble. Get a free case review.
