Build my inspection planHyundai Ioniq 5 · frequently asked questions
Is the Ioniq 5 reliable?
Yes, it has a strong reliability record, with most issues being minor software glitches.
Should I check the 12V battery?
Yes, early cars had some 12V drain issues, so checking its health is a sensible precaution.
Is battery degradation a concern?
Battery health is generally strong under the manufacturer warranty, but a health check report is still worthwhile.
Are there any structural concerns?
None significant, though checking for panoramic sunroof wind noise is worthwhile if fitted.
What are the servicing requirements for the high-voltage battery coolant?
The Ioniq 5 uses a specialised low-conductivity coolant for the high-voltage battery system. This must be replaced every 40,000 miles or 3 years, whichever comes first. It is a costly service procedure requiring diagnostic tools to bleed the system, so check the service history to ensure this has been completed on schedule.
Does the Ioniq 5 suffer from accelerated or uneven tyre wear?
Yes, due to the vehicle's kerb weight of over two tonnes and instant electric torque, rear tyre wear can be rapid, particularly on dual-motor AWD variants. Inspect the inner edges of the rear tyres carefully, as factory camber settings can cause the inner shoulders to scrub out significantly faster than the outer tread.
