THE CARS AUTO IDLE OFF FUNCTION THAT SAVES FUEL BY TURNING THE ENGINE OFF AT STOP SIGNS AND LIGHTS IN INOPERATIVE. I HAVE HAD IT INTO MULTIPLE DEALERS 4 TIMES SINCE 12/2020 WITH THE COMPLAINT. IN MY OPINION THERE IS A TEMPERATURE SENSOR THAT IS MALFUNCTIONING AND NOT ALLOWING THE CAR TO GO INTO THE FUEL SAVING MODE. I AM TOLD THAT THEY ARE NOT ABLE TO MAKE THIS FUNCTION WORK PROPERLY. WASN'T THE CAR CERTIFIED FOR EMISSIONS AND FUEL ECONOMY WITH THIS FUNCTION IN PLACE?

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 full 2019 Porsche 911 Carrera 4s Cabriolet verdict →
