Genesis Electrified G80
Dual-motor EV on Hyundai's E-GMP platform — 800V architecture, 18-minute 10-80% DC fast charging. Instant torque, zero mechanical drama. The ICCU recall (2022-2024) is the defining issue: the charging control unit overheats, stops feeding the 12V battery, and the car loses drive power. Nearly 150,000 Hyundai/Kia/Genesis EVs recalled. Even after the fix — fuse replacement, software update — 12V drain persists. Genesis recommends running the car 30 minutes every few days to keep the 12V alive. That is an unacceptable workaround for a $60k+ EV. Range is 236-282 miles EPA; degradation data still limited.
Silent luxury — if the 12V battery cooperates
The Electrified G80 is a 365 hp electric sedan with 800V charging and a 282-mile range. The ICCU recall is critical — without it, the 12V battery dies and the car won't drive. Even after the fix, some owners report persistent drain issues. The ride is serene, the torque is instant, and the cabin is the best version of the G80 interior. Range anxiety is manageable for commuters. A compelling alternative to the EQE if the recall is confirmed complete.
Engine Weaknesses 2
The Integrated Charging Control Unit (ICCU) can overheat and stop charging the 12V battery, causing loss of drive power. Nearly 150,000 Hyundai/Kia/Genesis EVs recalled. Dealer fix includes ICCU inspection, fuse replacement, and software update to reduce thermal loading and peak voltage. Affects 2022-2024 Electrified G80 and GV70.
Symptoms: 12V battery dead, vehicle won't start, loss of power while driving, dashboard warnings
Even after the ICCU recall fix, owners report the 12V battery draining within days of parking. High-tech systems stay active when the vehicle is off. Genesis recommends running the vehicle for 30 minutes every few days — an unacceptable workaround for a luxury EV. Multiple forum threads document ongoing issues across model years.
Symptoms: Dead battery after days parked, no-start, need for jump start, 12V low warning
Vehicle Weaknesses 4
Front seat belt pretensioners may explode during deployment, projecting metal fragments into the cabin. Affects 2021-2023 G80, 2020-2023 GV80, 2022-2023 GV70. NHTSA recall — free dealer repair. Critical safety issue.
Parasitic drain from always-on systems (DSC, TPMS, connected services) can kill the 12V battery within days of parking. Not limited to EVs — ICE G80 models affected too. Genesis recommends periodic driving to maintain charge. Some owners install battery tenders.
AC evaporator coil breaks at the same joint repeatedly — dealers go through dozens of coils monthly. Dashboard removal required for replacement (2-day job). Condensers also fail routinely on early models. No formal recall despite widespread complaints.
Same paint quality concerns as the G70 — soft clear coat, easy chipping, premature peeling. Door handle clear coat delamination documented on multiple G80 units. Part of the Genesis-wide class action (Russo v. Hyundai, 2024).
