Electronic Alerts & Nags

5 issues reported

The speed limit warning system beeps when exceeding posted limits but reactivates automatically every time the car starts, requiring multiple menu presses or button sequences to disable again.

The driver assistance eye sensor detects when the driver looks away from the road and issues loud alerts or chimes, often after just 3 seconds, with no permanent disable option.

After front sensor removal (e.g., during service), the car emits beeps at every stop and turn, requiring a button press each time to silence.

The second-row seat belt alarm cannot be permanently disabled, even with a child seat installed, forcing manual intervention each drive.

After installing V2X OTA update v25.6.1, the EV9 fails to charge, potentially bricking the battery management system (BMS) with error P1AA700, requiring full battery replacement per dealer diagnosis.

Incomplete or failed OTA updates cause driving errors like C28B186, initially mistaken for 12V issues, resolved only after successful satellite/GPS-based update completion.

Post-'V2X Enhancement' OTA update, Kia Connect app remote commands fail with 'OTA Update Task could not be performed' error, though battery status updates; multiple users report the issue.

OTA updates lead to excessive phantom drain on 12V battery and random top-off charges (e.g., 79% to 80%), linked to features like mobile key and wireless charger.

12V battery dies unexpectedly after Kia software update, despite prior reliability and precautions against parasitic drain.
