Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“On 3 separate occasions while making a left hand turn against traffic, the car has initiated emergency braking and shown the ‘collision warning’ alert on the dashboard. Each time there were no cars approaching and the car halted to a complete stop. The first two instances I had my 10 year old in the car. Tonight I was alone. It is terrifying and I know this is not a rare occurrence with Porsches. An online forum has tons of other Porsche owners saying the same thing and we are being encouraged to file a report with NHTSA.”

Onset of Failure & Dashboard Alerts - While maintaining speed, the vehicle suffered an immediate, simultaneous electronic and mechanical malfunction. The dashboard abruptly displayed an Adaptive Cruise Control (ACC) error/failure warning, along with auto start/stop failure. …”
