Hyundai Cases Under Montana Lemon Law

Hyundai and Genesis cases in Montana — Theta II engine failures/fires, oil consumption, and Ioniq EV defect patterns, with cold and high-mileage factors.

Hyundai (including Genesis) has a solid Montana market share — Tucson, Santa Fe, Kona, Elantra, and Palisade are common, with AWD trims favored for winter. Cases are pursued under the Montana Lemon Law, the CPA, 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), cold-weather charging.
  • Theft-vulnerability software issues (Kia/Hyundai immobilizer).

Montana Hyundai market

  • Tucson / Santa Fe / Kona / Palisade AWD for winter driving.
  • Elantra sedan volume.
  • Growing Ioniq EV presence.

Safety + CPA leverage

Theta II engine fires are a serious safety matter, and the deep recall/class-action history supports a CPA theory with a discretionary treble. Extreme cold aggravates Ioniq ICCU 12V issues; mag-chloride drives electrical corrosion.

Bottom line

Hyundai cases — Theta II engine failures/fires, oil consumption, and Ioniq ICCU — are strongly positioned under Montana law. Use in-state arbitration, and act before 18,000 miles. Get a free case review.
