2024 Porsche MacanRecalls, problems, MPG & safety

“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.

At the next light, I shifted into Park and then back into Drive; the revving temporarily subsided. I stopped briefly at a drive-through pharmacy and then drove directly home. As I pulled into my driveway with my foot on the brake, the vehicle suddenly accelerated sharply on its own and struck my home, causing significant damage to the house and vehicle. Smoke came from the front of the vehicle. Because I live in an attached home and my neighbors were inside, I attempted to back the vehicle a few feet away. With my foot on the brake, I shifted into Reverse, and the vehicle again…”
