“Catastrophic coolant loss due to failure of a known issue by manufacturer. The coolant loss resulted due to failure of the epoxy that held the hose to the manifold. The epoxy failure affected 3 of the hoses. This was part of a DOT bulletin affecting this model year. Failure on my vehicle came later after warranty had expired due to low mileage. Also in 2021 the rear lid spoiler failed (another known high failure issue known to manufacturer) due to hydraulic fluid loss. Both repairs came at a extremely high cost and manufacturer refused consideration for help unless vehicle was repaired at their own dealer. This after I had made contact and advised them of location of vehicle at a service facility that is recognized by manufacturer as a credible alternative to their dealer.”

IT TOOK TWO WEEKS AND SEVEN CONTACT ATTEMPTS TO GET ANYONE AT PORSCHE TO REPLY. THEY HAD THE CAR TAKEN TO PORSHE OF ORLANDO. PORSCHE OF ORLANDO REPLACED THE WINDOW THEN TOLD PORSCHE NA THERE IS NOTHING WRONG WITH THE CAR. AMANDA AT PORSCHE CALLED US AND TOLD US TO PICK UP THE CAR AND TURN IT INTO OUR INSURANCE COMPANY AS THEY WILL DO NOTHING MORE. REGARDLESS IF THERE IS A PROBLEM WITH THE CAR OR IF IT WAS A DEFECTIVE PIECE OF GLASS PORSCHE SHOULD BE RESPONSIBLE FOR FIXING THE DAMAGED PAINT AND FIXING THE INTERIOR (SCRATCHED INTERIOR PIECES, TORN SEAT.) THE CAR ALSO HAS A DIMENISHED VALUE NOW THAT IT HAS TO BE PAINTED AND IT IS…”
