2024 Porsche Macan

While driving on a major highway ([XXX]) at over 60 MPH, we had a complete and catastrophic system wide shut down of our vehicle, culminating in our car grinding to a halt. This entire process elapsed over a 15-20 second period. We barely were able to get our vehicle to the "left" shoulder along the median of the highway where we had to sit for over 75 minutes with oncoming traffic racing past us until 911 arrived to tow us. It was a life-threatening situation where we were virtual "sitting ducks" without any means to remove ourselves from harms way. The car was immovable and unresponsive. We tried to restart the car with the assistance of our Porsche Dealer but nothing worked. We had no choice but to pray for our safety. We have completely documented our experience: photos, videos and phone calls with 911. NOTE: your system is not allowing us to upload any of our photos or videos but we would like to provide these to you directly so please reach out to me to let me know how we can share these with you. When the car malfunctioned, it seemed that every alert in the car's computer system flashed in serial fashion - Engine Control Error, P Button Defective, E Sound Error, Lane Assistance Malfunction, Electrical Parking Brake Error. It should be noted that we have had the car for less than two years and have logged a little over 11,000 miles driven. Ultimately, we were towed by flat bed to the nearest Porsche Dealer in White Plains where the car is parked. We left a message for the service department at the Dealer telling them who we are, what happened and to call us before they begin an inspection.

Collion Warning alarm came on with full application of brakes with no vehicles in front or behind. No onward traffic either. Visibility was clear, and driving conditions good. Driving at 35-40 mph. Informed dealer three times (and three different individuals) on December 31 and despite a bevy of promises they have taken no action. Placed warning on Macan.com and several other (purported) owners claimed to have experienced an identical issue. This is self-evidently highly dangerous. Lack of responsivess from Porsche dealer [XXX] ) has also been derisable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My car has intermittently triggered false collision warnings—approximately 8 to 10 times over ~8,500 miles. Each time, while driving between 20–40 mph with no visible obstacles, the system issued an orange collision alert, sounded an alarm, and abruptly applied the brakes. This sudden braking poses a serious safety risk, as it could cause a rear-end collision. The vehicle has been at the dealer for 14 days and remains there, as they’ve been unable to replicate the issue or find any stored fault codes.

I was driving at 40mph on a town road on a dry, sunny day when, without warning, the brakes slammed on extremely forcefully, almost to a full stop, and a big triangle showed on the dashboard with the words COLLISION WARNING. I don’t recall if there was an audible alarm or not. The warning disappeared and the car resumed forward motion almost as quickly as it had appeared. My body jolted forward against my seat belt and items on the passenger seat went flying forward and fell on the floor. There were no other cars on the road at the time but, if there had been anyone in back of me, it very well could have caused an accident. My neck and chest are quite sore the day after this happened. I stopped the car and walked around outside and did not see anything out of the ordinary - nothing in the road either. It was a paved secondary road without potholes in the immediate vicinity. The dealership will be picking up the car to inspect it and implement an “alert” upgrade service for the front camera system that may or may not have any connection to the problem.
