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.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
