On Saturday 10/24/26 at approximately 6:45 PM I pulled into my garage and pressed the engine button to shutdown the car after parking in my home garage.

issue occurring with automatic start/stop function. car stalls on occasion trying to restart, goes into neutral, even though battery is new and in good condition. hard to replicate and occurs randomly. car has to be turned off and on again. this is the 4th time this has happened over the course of 3 years. seems to be happening to others based on forums as well.
