- 20,000+ miles
- What to inspect
- Check the 12V battery condition and ask about any flat battery history

A 2024 Kia EV6 is now 2 years old, so an average example has covered around 27,000 miles. A late-run car · the most reliable part of the generation, but higher-mileage wear items are usually the deciding factor. Check the state safety inspection and service history alongside the documented faults below, which are sorted by whether a 2024 car has usually reached the mileage where they appear.

Build my inspection planYes, they share the same platform and have a similarly strong reliability record.
Yes, early cars had some 12V drain issues, so a health check is a sensible precaution.
Not generally, but always request a battery state-of-health report before purchase.
Minor rattles around the centre console occur but are inexpensive to resolve.
While not strictly mandatory, it is highly recommended to fit EV-specific tyres featuring acoustic foam inserts. The EV6 is a heavy vehicle with instant torque, which accelerates tyre wear. Standard tyres will noticeably increase cabin resonance and road noise, detracting from the refinement expected by buyers. Always check tread depths carefully during appraisal.
A heat pump was optional on lower trims and standard on higher-spec models like the GT-Line S and GT. To verify, open the bonnet and inspect the front under-bonnet storage area. Models with a heat pump have a visibly different, more complex pipework arrangement on the right-hand side of the front boot surround.
