I drive an 2019 Audi A5 and there is a terrible auto start/stop malfunction and cruise control malfunction that has made this car unsafe to drive. The auto start is featured on the A5 to "save gas," but however malfunctions and cuts off while driving or coming to a stop. Tonight on 1/21/2025 at 1:44 am it did just that. While sitting at the light it stalled out, manually crank it up attempt to get thru the light and it cuts off leaving my son and I stranded dead center of the intersection leaving the two of us sitting ducks. I look and there is traffic coming and we were nearly taken out by an oncoming vehicle after my 5th attempt to start up the car before finally pulling off. Prior I was alone in traffic where the auto stop again malfunctioned, cut off, and caused me to roll backwards almost hitting a vehicle behind me. The cruise control also malfunctions at random. This vehicle has become not only a high risk but a danger to operate on any highway at this point and I've only had it 2 years. It is an extremely beautiful car, but is not worth my life, my son's, or anyone else sitting in the car.
