Hyundai Ioniq air conditioning not working - is this a manufacturer fault?

My 2021 Hyundai Ioniq Electric's air conditioning has been out of order for two months and has had four separate visits to the dealer, who doesn't seem to have any idea what to do to fix it. It is now with Hyundai technical. The dealer is awaiting their advice.

They initially said it probably needed a regas, then it needed a new compressor, then said it needed more extensive diagnostics, now they are seeking advice from Hyundai.

Are you aware of many other similar complaints? I have found reports of this issue from other countries but not the UK.

It reads as if the AC system has failed. Either the compressor has seized up or the joints have dried out and the gas is escaping quicker than they can top it up.

If the problems are linked by a manufacturing fault then it should be covered by Hyundai's warranty. However, if you the problems are caused by lack of use them your warranty claim may be rejected.

The AC system is designed to be used all year round. Switching it off for the winter months will increase the likelihood of the joints during out or the condenser failing.
