What's wrong, in plain English

Some Cayenne GTS vehicles have an engine problem where cracks can develop on the surface inside the engine cylinder. Over time, these cracks may cause damage to the engine, which could make the engine stall while you are driving, or cause the engine to develop an oil leak. Porsche dealers will replace the entire engine completely, free of charge, to fix the issue with these vehicles.
