Hyundai Cases Under Washington Lemon Law
Hyundai cases in Washington — Theta II engine failures, Smartstream transmission, Ioniq 5/6 EV, and Genesis luxury patterns.
Hyundai (including Genesis) has strong Washington market share — particularly Tucson, Santa Fe, Palisade, Elantra, Sonata, Ioniq 5 / 6, and Genesis G70 / G80 / G90 / GV70 / GV80. Hyundai cases are pursued under RCW 19.118 (Washington Lemon Law) and WCPA.
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 (Integrated Charging Control Unit) — 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.
Check NHTSA for your VIN.
WCPA Hangman Ridge fit
Hyundai cases strongly support WCPA Hangman Ridge public-interest impact:
- 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 Washington Lemon Law and WCPA. The Theta II engine pattern is among the strongest pattern evidence available across U.S. lemon-law practice.
