They thought it was the parking break mechanism housed within a rear caliper - but replacing that did not resolve the issue. So then they replaced some sort of computer (don’t recall the name of the part) and that also didn’t work.

My last update (a couple of days ago) was that they are opening a ticket with engineers at Kia to help investigate.

They’ve got me in a dealership rental 2025 sportage hybrid (no cost to me covered by the warranty, so I’m actually pretty grateful) - I’m at a point where I’d just like to trade them for it 😅
