When starting from a full stop and traveling approximately 25 mph, a car crosses in front of me. I make an emergency stop to avoid a collision. The car will then not shift out of first gear. I then must safely get off the highway, stop the car and when I restart the car everything works fine. This has occurred three times under almost the exact scenario over the first year of operation. This problem provides an unsafe condition for the car’s occupants as well as others on the road. I have had the car inspected by three separate Porsche dealers. Their position is that they can find no problem with the car, but have never tried to reproduce the event (to dangerous). I have volumes of reports from Porsche, all saying that they can find no problem with the car .

Brakes slammed on and hard left turn initiated. Collision warning light flashed. There was nothing in front of me. Action caused an artery to tear in my lung. Hospitalized with life threating injury. Car had recently received 1st year service. Called dealer service manager to report failure, he said the car could not do this. Car has not been inspected at this time. Lawyer advised not to drive car, but also said his team had no equipment to review failure, needed to be taken to dealer who would probably not work with him. There are many of these failures on the internet, Also have friends how have had similar issues multiple times. How do i proceed?

Vehicle suddenly slammed on brakes on highway I90 in Chicago for NO apparent reason at 25mph. The car came to an immediate halt and if not for shoulder cars behind me would have stuck me. I am afraid to drive car. Dealership down plays faulty sensor, car has 2,000 miles. What assurance do I have to trust new sensor. System not redundant. I had no control of my vehicle and my life was at jeopardy. I will not trust.cat. Porsche is aware of issue for years yet nothing done to resolve. Phantom braking concerns litter the internet
