There are 5 owner-reported fuel system complaints for the 2024 Kia EV9in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
At least one cell of the ev battery is defective and the battery will not charge. The dealer determined that it is unsafe to drive. We are pending repairs and under warranty for over 40 days now and Kia can provide de no estimate for when the car will be repaired.
Vehicle range went from 320+ miles on a 100% charge to just 100 miles on 100% charge. Looks to be a bad battery cell or battery itself. No warning lights of any kind. Just super degraded range. Vehicle is new and has around 5800 miles. Dealer doesn't have techs to work on batteries, so they are having to play telephone game with Kia tech line in Korea.
Starting on Feb 22, 2025, we observed that our Kia EV9 had dramatically reduced range. Normally, when charging was complete the dashboard would show well over 250 miles of range, even in cold weather. On Feb 22nd we started to see the range had dropped to around 60 miles, even when the dashboard reported the battery at 100% charge. The actual range seemed to be even worse, dropping dramatically even after a short drive around our town. By all appearances, the high voltage battery seems to be defective and is causing a safety issue because it could result in a sudden loss of power during driving or an unexpected shutdown of the vehicle. This may also be a symptom of an even more serious battery defect that could result in a battery fire. We brought the vehicle to the dealer, and they were able to reproduce the severe drop in range. No components have been replaced yet, we are still waiting to hear which parts will be replaced under warranty service. During this entire time the vehicle has given zero warnings or alerts, including no warning messages nor the check engine light.
Vehicle failing to charge beyond 65% state of charge. Error message P1AA700 (warning) appearing on the dash with an electrical charging system issue. Kia Customer Care Case Number: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
I recently had recall 24V693000 completed on my vehicle. After the recall while using the remote vehicle movement feature it no longer stops at all. While demonstrating the feature for a friend interested in purchasing a similar vehicle it did not stop and I had to move and release the remote to stop the vehicle. I have tested it again twice and the same problem occurs, the vehicle does not detect a pedestrian behind it and does not attempt to stop or stop.
