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.

On two occasions so far, when making a left turn in a four way intersection, the pre-sense system detected an oncoming car way too early and applied the brakes hard just as I was well into the turn and needed to get out of the intersection before I became a danger to the oncoming car. This put me into a potentially very dangerous situation. I am aware that the sensitivity can be adjusted but, in this case, there was no danger at all until my car braked suddenly as I was trying to complete my turn safely. That actually created a hazard. As with other similar complaints that I have read about, I believe that the software is still somewhat imperfect. I have since selected the least sensitive setting and have had no further problems. The pre-sense system has also braked hard several times when backing up even though any potential danger was still well away from my car. The braking is so harsh and startling, that alone could cause unintended consequences.

This is another occurrence therefore a continuation of complaint number 11258717. On a second occasion while driving in the express lanes of an expressway, the pre-sense displayed a crossroad indication on the instrument display and applied the brakes while I was going approximately 75 mph on a limited access expressway in the express lanes. Can you imagine what would have happened if I had a car tailgating me at that time" there is some serious software defects with this system. Is anyone going to respond to this"

I was stopped in a turn lane to make a left turn across 3 lanes of opposing traffic on a major us highway.. I started the turn and the pre-sense system stopped the car as it was entering the opposing lane of traffic almost causing a disaster as the oncoming traffic was moving approximate 50-60 mph. Fortunately for the oncoming car, the lane adjacent was empty at the moment so they could move over and pass me safely as I was stuck in the lane of the oncoming traffic with the brakes automatically applied.
