Hyundai & Kia E-GMP Common Problems (IONIQ 5, EV6, GV60)

Common E-GMP issues

1. 12V battery drain - the most reported E-GMP issue. Fix: update software (the recall campaign) and keep the 12V charged; some owners install a solar trickle charger.
2. ICCU failure warnings - a known recall; the dealer replaces the integrated charging control unit under warranty.
3. Slow port open / charge delay - usually a software update fixes charge-port latency.
4. AWD models and efficiency - expect less range than RWD; not a fault.
5. Kia Connect / Bluelink app delays - update and re-login.

What to do

1. Install all recall software updates - Hyundai/Kia push fixes via dealer visits.
2. Keep the 12V battery healthy - drive regularly or use a maintainer.
3. For anything electrical, book a dealer - E-GMP systems need factory diagnostics.

Bottom line

The E-GMP drivetrain is excellent. Most reported issues are the 12V battery and ICCU, both covered by recalls.
