Hyundai Cases Under Massachusetts Lemon Law

Hyundai (including Genesis) has strong Massachusetts market share. Hyundai cases are pursued under § 7N½ (Massachusetts Lemon Law) and Chapter 93A.

Common Hyundai defect patterns

• Theta II GDI engine failures (long-standing pattern; multiple class actions; ongoing recalls).
• Smartstream IVT (CVT) issues.
• 8-speed automatic shift issues.
• Ioniq 5 / 6 ICCU (Integrated Charging Control Unit) failures.
• E-GMP platform OTA, BMS issues.
• Palisade / Telluride electrical glitches.
• Sonata Hybrid battery cooling issues.
• Bluelink connectivity failures.
• N-line / N performance models clutch issues.

Ioniq 5 / 6 EV patterns

• ICCU failures (paradigmatic Hyundai EV issue).
• DC fast-charging throttling.
• 12V auxiliary battery dead.
• OTA update history.
• Range degradation.

Genesis-specific patterns

• G80 / G90 air suspension issues.
• GV70 / GV80 infotainment crashes.
• Electrified GV70 EV BMS issues.

Hyundai TSB / recall overlay

Heavy TSB pattern:

• Theta II GDI engine recalls (broad scope).
• ICCU TSBs / OTA updates.
• Bluelink connectivity TSBs.
• Smartstream IVT TSBs.

Chapter 93A willfulness fit

Hyundai cases strongly support c. 93A willfulness:

• Theta II GDI class-action history (paradigmatic pattern evidence).
• ICCU emerging class-action pattern.
• Multi-state lemon-law actions.

Bottom line

Hyundai cases — particularly Theta II GDI engine and Ioniq 5/6 ICCU cases — are well-positioned for Massachusetts Lemon Law and Chapter 93A. The Theta II engine pattern is among the strongest pattern evidence available across U.S. lemon-law practice.
