Kia Cases Under Washington Lemon Law

Kia cases in Washington — Theta II engine failures (shared with Hyundai), Smartstream transmission, EV6 / Niro EV, and Telluride patterns.

Kia (Hyundai Motor Group sibling) has strong Washington market share — particularly Sportage, Sorento, Telluride, Forte, K5, EV6, Niro EV, and the new EV9. Kia cases are pursued under RCW 19.118 (Washington Lemon Law) and WCPA.

Common Kia defect patterns

  • Theta II GDI engine failures — shared with Hyundai (long-standing class action).
  • Smartstream IVT / 8-speed transmission issues.
  • EV6 / Niro EV / EV9 ICCU failures (shared E-GMP platform with Ioniq).
  • Telluride infotainment / electrical issues.
  • Sportage / Sorento transmission issues.
  • Stinger issues (limited remaining inventory).
  • K5 GT-Line / GT issues.

EV6 / EV9 / Niro EV patterns

  • ICCU (Integrated Charging Control Unit) failures — paradigmatic E-GMP issue.
  • DC fast-charging throttling.
  • 12V auxiliary battery dead.
  • OTA update history.
  • Range degradation.

Kia TSB / recall overlay

Heavy TSB pattern (shared with Hyundai):

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

Check NHTSA for your VIN.

WCPA Hangman Ridge fit

Kia cases strongly support WCPA Hangman Ridge public-interest impact because of the shared E-GMP and Theta II platforms with Hyundai — pattern evidence translates directly across the corporate group.

Bottom line

Kia cases mirror Hyundai cases — Theta II GDI engine and E-GMP EV patterns provide strong WCPA pattern evidence. The Pacific Northwest’s strong Kia market share creates substantial case volume.
