Porsche Cayenne owners have reported 1 problem related to automatic emergency braking (under the forward collision avoidance category). The most recently reported issues are listed below. Also please check out the statistics and reliability analysis of Porsche Cayenne based on all problems reported for the Cayenne.
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.
