In my Focus RS the start stop was terrible. It had an issue where if you try to go quick there was a delay in throttle response after it restarted the engine causing me to stall sometimes. Luckily start/stop required a high state of charge on the battery and pretty much stopped working after the first year.

You can verify by removing the wire from the coil to the stop switch and testing again. You can also buy inline spark testers from Harbor Freight and most auto parts stores that light up a bulb, they're much It is not. Oddly enough, fired it up this morning and it was working like it never stopped. Not sure if resetting the radio and then letting the car sit off for awhile is what did it, but it's working now. I had something similar in my 2023 Sportage I believe. No audio, steering wheel controls wouldn't work, nothing. OeqieF0. 21131084145300125390467
