2024 Porsche Macan Forward collision avoidance Problems

“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. …”

“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.”
