My Kia EV9 Isn't Working — What to Check First

Kia's EV9 is a flagship 3-row electric SUV. Premium hardware = more service complexity. Most issues are software + ADAS calibration.

This guide is built from real Kia EV9 repair cases handled at ev.care's workshops in Delhi (expanding to 30+ Indian cities by 2027). Every step below has been verified by our DIYguru-certified technicians — the same engineers who fix these vehicles for the country's leading EV fleets. If you're stuck on any step, our free 2-hour callback will diagnose it for you.

2. GMP 800V system not entering 350kW charge mode

If a fault repeats after the steps above, if any dashboard error code is showing, or if you notice any unusual smell, heat, or sound from the battery pack — stop driving. Kia EV9 battery and motor faults compound: a minor BMS imbalance left untreated can kill the whole pack inside 6 months.
