SEVERAL TIMES A MONTH WHEN MY CAR COMES TO A STOP THE BRAKES MALFUNCTION AND THE BRAKE PEDAL GOES TO THE FLOOR AND THE POWER STEERING STOPS WORKING. IT TAKES UP TO ANOTHER CAR LENGTH TO FULLY STOP WHEN THIS HAPPENS - SOMETIMES JUST A FEW EXTRA FEET. IT HAS CAUSED ME TO DAMAGE THE FRONT END BY DRIVING INTO A BUSH. THE DEALER REFUSES TO DO ANYTHING BECAUSE THEY CAN'T REPLICATE THE BRAKE PROBLEM AND THEY STATE THE STEERING PROBLEM IS NORMAL. I HAVE BEEN ABLE TO REPLICATE THE STEERING PROBLEMS TO THEM BUT BECAUSE THE BRAKE ISSUE HAPPENS ONLY A FEW TIMES A MONTH I WAS NOT ABLE TO.

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 Cayenne verdict →
