Kia EV9 owners report battery issues and long repair delays

TL;DR

  • •Kia EV9 traction battery shows false charge levels and reduced capacity
  • •Diagnostic scans found damaged modules inside the battery pack
  • •Warranty battery replacements delayed by supply chain issues
  • •Dozens of cases reported in the UK and US without official recall

Why it matters

Battery failures in electric vehicles undermine consumer confidence and create financial risks for manufacturers. Kia's slow response to these defects could damage its reputation in the rapidly growing EV market segment.

Technical Details

Kia EV9 owners report erratic battery behavior: charge levels jump from 82% to 100% while the estimated range drops suddenly. Diagnostic scans show the battery only stores 71 kWh instead of the advertised 99.8 kWh when displaying 100% charge. Multiple modules inside the battery pack are damaged.

Context and Background

The issue began with a drained 12V battery that prevented the car from unlocking. Kia service centers confirmed the defect and offered full battery replacement under the 8-year warranty. However, part shortages have created indefinite repair delays.

Industry Impact

Dozens of similar cases have been reported in the UK and US. Owners are stuck waiting for new battery packs, which could accelerate skepticism toward EV technology. Kia has not issued an official recall, raising concerns about its crisis management in the competitive EV market.
