Example complaints

“The coolant line connectors that come out of the engine / block are dislodging from the engine blocks and blowing out all of the coolant in a matter of seconds. Porsche used some sort of adhesive to hold the connectors in the block instead of welding them in; as the cars age and go through lots of heat cycles, the adhesive is wearing out and the connectors are blowing out of the engine block causing a massive coolant dump which can be dangerous if traveling at freeway speeds.”
