Beginning one year after buying this used 2020 Subaru Crosstrek base trim the starter failed and battery fully died after failing to start from a stop. The engine was OFF due to the auto-stop system and failed upon lifting my foot from the brake on a slight incline, causing a constant warning beep and a starter system failure message on the dash display. Immediately after failing to start the brake pressure significantly dropped causing my car to roll into the front of the car behind it. The car was stranded in the road and required a jump start. Since this event the issue has occurred twice more on two brand new batteries on no incline, and I now fully disable the auto-stop feature before driving to avoid an accident. The car starts properly with no battery damage if started from the full ignition off position, even if auto-stop originally stopped the engine, pointing to a failure of the auto-stop system specifically. Importantly, I have also personally seen this exact failure occur to a separate 2020 Subaru Crosstrek, with the sport trim.
