Build my inspection planFrequently asked questions
Is the EV6 as reliable as the Ioniq 5?
Yes, they share the same platform and have a similarly strong reliability record.
Should I check the 12V battery before buying?
Yes, early cars had some 12V drain issues, so a health check is a sensible precaution.
Is the EV6's battery health a concern?
Not generally, but always request a battery state-of-health report before purchase.
Are there any trim quality concerns?
Minor rattles around the centre console occur but are inexpensive to resolve.
Do I need to fit specific EV tyres to the EV6?
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.
How can I tell if a specific EV6 is fitted with a heat pump?
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.
