My Karoq 1.5 Tsi Drive, manual, new on March 1st, 2024, had the same symptoms...losing power randomly at junctions and roundabouts. I was left in dangerous situations on several occasions. The car would fire up again after 5-10 seconds, only by pressing the ignition button on the column. I took it to the nearest Skoda dealer three weeks after delivery. They found nothing wrong after diagnostic testing. They, too, said the issue was new to them. Another dealer refused to test the car, saying that their diagnostic equipment would be the same, so not to bother bringing the car in for testing. Every time I got in the car, the first thing I did was to turn off the start/stop function. I tried E5 petrol...no difference. I began to plan my driving routes so as to avoid as many junctions/roundabouts as I could. My car was on a 3-year Personal Hire Contract. Eventually, after regular stress to my passengers and myself, I got Skoda Finance involved. I managed to get my contract terminated, without penalty. I am now awaiting delivery of a Qashqai! Let's hope for better times ahead!
