Hyundai Cases Under Arizona Lemon Law

Hyundai (including Genesis) has strong Arizona market share. Hyundai cases are pursued under A.R.S. § 44-1263 and Magnuson-Moss.

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 (Arizona heat).
Bluelink connectivity failures.

Ioniq 5 / 6 EV patterns

ICCU failures.
DC fast-charging throttling.
12V auxiliary battery dead.
OTA update history.
Range degradation in Arizona heat.

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; paradigmatic CFA pattern evidence).
ICCU TSBs / OTA updates.
Bluelink connectivity TSBs.
Smartstream IVT TSBs.

Bottom line

Hyundai cases — particularly Theta II GDI engine and Ioniq 5/6 ICCU cases — are well-positioned for Arizona Lemon Law. The Theta II engine pattern is among the strongest pattern evidence available across U.S. lemon-law practice — supporting CFA punitive pleading within Arizona’s 1-year SOL.
