Hyundai Lemon Law Cases in Connecticut

Hyundai (and its Kia + Genesis siblings) has growing Connecticut market share. Connecticut Lemon Law applies fully.

Common Hyundai defect patterns

• Theta-II 2.0L / 2.4L engine — Sonata, Santa Fe, Tucson (older). Recall + extended warranty. Connecting-rod failure.
• Nu 1.8L / 2.0L — engine seize issues.
• Smartstream 2.5L — newer engine, fewer issues so far.
• DCT — Veloster, Tucson DCT issues.
• Ioniq 5 / Ioniq 6 ICCU — Integrated Charging Control Unit failure (recall). 800V system.
• Kona EV / Kona ICE — both have separate defect patterns.
• Palisade — infotainment, fuel-system issues.
• Genesis G70 / G80 / G90 — generally reliable; sporadic transmission, infotainment.
• Bluelink connectivity — service issues.

Theta-II engine recall

Massive recall covering 2011-2019 Hyundai Sonata, Santa Fe, Tucson (and Kia Optima, Sorento, Sportage). Connecting-rod failure leading to engine seize / fire.

Lifetime warranty extension on engine for recalled VINs. Lemon Law claims still viable where:

• Engine fails post-recall remedy.
• Repair not completed by Hyundai.
• Refusal to provide loaner / rental.

Ioniq 5 / 6 ICCU recall

Integrated Charging Control Unit failure in 800V Hyundai/Kia EVs (Ioniq 5/6, EV6, Genesis GV60). Recall + extended warranty. Strong CT case if ICCU fails post-recall.

Hyundai IDS / arbitration

Hyundai uses BBB Auto Line as certified IDS. CT consumers can:

• File DCP arbitration.
• File BBB Auto Line.
• File court action.

DCP is generally preferred.

CUTPA in Hyundai cases

• Theta-II disclosure — known issues across model years.
• TPMS / Kia Boys — anti-theft deficiency CUTPA claims.
• Ioniq 5 charging — promised charging speeds vs. real-world.

Bottom line

Hyundai is fully covered under Connecticut Lemon Law. Theta-II engine failures, ICCU recall, and EV charging issues are the primary case patterns. File DCP arbitration or court action.
