Ignit switch intermittent latency/hesitates starting, AC blows warm

Hello, this sounds quite frustrating, to be sure. The unfortunate part is that if the compressor has indeed failed, there is no way to correlate this to an engine replacement or engine failure. The same with your ignition - first, they'd have to duplicate the concern then determine what is causing it. You can certainly get second opinions from a non-dealership shop near you. If they find something related to engine replacement, then you'll have information to share that could help you get help. If not, then you'll have an independent assessment at least and maybe a better price for repairs. You can also reach out to Kia itself, corporate, to share your concerns and plead your case for assistance. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
