As Im old school Bmw where brake trouble was as simple as taking her off the ground and manually cleaning/replacing & recalibrating the brake system. What the hell is going on with this car. Ok, electronic brakes.... Electronic wind back, Sticking calipers, (which a speed ramp is enough to trigger) One caliper randomly failing. This is not acceptable as the stopping safety of a vehicle, but yet its not covered on Hyundai warranty. Its mechanically, a great car, but unfortunately, not safe on stopping in emergency situations. I ran it through an NCT, National road safety test in Ireland. And horrifically, it passed on brake testing. Which leads me back to my theory of a random intermittent caliper fail. I stripped this caliper down, to find gritty/sticking caliper pistons and slide pins. At 70k this is not expected but ok, nothing is perfect. Replaced these parts along with new pads and discs and also reset the system, all good so far.. 4k later. Cant wait to sell it.
