On the backside of this v8 engine there is a coolant distribution tube that has coolant barb pressed into the cast aluminum distribution tube with adhesive. While driving from wor to home, the adhesive failed 19mar20 causing the barb to slip out of the tube allowing large amounts of coolant to gush over the hot exhaust and out from under the Cayenne. The engine control unit recognized low coolant level the dash panel flagged "low coolant" and the vehicle was pulled over before overheating the engine. Fortunately due to the teleworking status of where I work there was no traffic behind me and thankfully no motorcyclist. I would expect more a $71,145 vehicle from Porsche even after 12 years and 140k mi.
