NHTSA Complaint #11539035 — 2019 VOLKSWAGEN GOLF ALLTRACK

After being in hot sunlight all day(95+ degrees), car started and about three minutes into drive the engine and all electronics died while going approximately 15mph, warning display flashed up on center lcd display that ignition was off, please pull over, and then to check the starter. The power steering turned off so I had very limited steering. The car would not restart, took about 5 minutes of waiting and had to remove the key and reinsert it before it would start again. I was only going 15mph on an empty residential road, so no damage, but if it happened on a busy highway it might have resulted in a crash. Dealer could not reproduce the fail, but read codes that showed the ignition switch was faulty, and they replaced that. The car was at the dealership to look at another issue(the blind spot monitor lights not turning off), and I picked it up from the dealership minutes before this ignition switch issue occurred. They found no issues or error codes with the blind spot monitoring or any other electrical system, the ignition switch issue only occurred after the car was sitting outside in direct sunlight for 5 hours. I believe the heat was the issue, I have found multiple online forum posts where owners of 2019 VWs of different models have the same issue on hot days.
