What 2026 Porsche Cayenne owners say
Driver assistance
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.
The warning system continues to showing warnings and the Blind Spot and Adaptive Cruise Control render the car unsafe to drive. The other warnings has no impact of the functioning of the cars ability to be driven. After many false warnings, my wife almost ran a car off the road the first time the blind spot failure waring appeared as she had not notice it.
