MY 2011 PORSCHE CAYENNE HAS AN "AUTO STOP" FEATURE THAT KILLS THE ENGINE WHENEVER THE CAR IS STOPPED AT A STOP LIGHT OR STOP SIGN. WHEN THE DRIVER'S FOOT IS REMOVED FROM THE BRAKE, THE CAR ENGINE RESTARTS. THE STOP-START DELAY IS POTENTIALLY DANGEROUS. I WAS ALMOST REAR-ENDED BY A CAR THAT WAS BEHIND ME BECAUSE THE DRIVER WAS ANXIOUS TO "MOVE" AND MY CAYENNE'S ENGINE HAD TO RESTART BEFORE IT WOULD MOVE FROM THE STOP LIGHT. THIS SPECIAL FEATURE CAN BE TURNED OFF, BUT YOU MUST TURN IT OFF EVERY TIME YOU START THE CAR. OTHERWISE, THE AUTO STOP FEATURE WILL CONTINUE TO OPERATE. I CONSIDER THE AUTO STOP FEATURE TO BE PROBLEMATIC. *TR

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your
pre-purchase inspection list. Back to the
