2008 Saturn Sky Engine Problems

I AM TRYING TO REPLACE THE TURBOCHARGED UNIT BUT ALL 3 PURCHASE HAD AN INTERNAL CRACK. IS THIS A COMMON PROBLEM UNKNOWN BY CONSUMERS? SHOULD I BE WORRIED THAT THIS PROBLEM WILL CONTINUE?

TL* THE CONTACT OWNS A 2008 SATURN SKY. WHILE DRIVING VARIOUS SPEEDS, THE COOLANT WARNING INDICATOR ILLUMINATED. THE CONTACT MENTIONED THAT COOLANT WAS ADDED TO THE VEHICLE EVERY TWO DAYS. AN INDEPENDENT MECHANIC STATED THAT THE COOLANT SYSTEM NEEDED TO BE FLUSHED. THE VEHICLE WAS REPAIRED; HOWEVER, THE FAILURE PERSISTED. THE VEHICLE WAS TAKEN TO HARRY GREEN CHEVROLET NISSAN (1858 E PIKE ST, CLARKSBURG, WV 26301) WHERE THEY FLUSHED THE COOLANT SYSTEM. THE VEHICLE WAS REPAIRED; HOWEVER, THE FAILURE PERSISTED AGAIN. THE VEHICLE WAS TAKEN BACK TO THE HARRY GREEN DEALER WHERE IT WAS DIAGNOSED THAT THE THERMOSTAT AND THERMOSTAT HOUSING NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED AND WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE THE CAUSE OF THE FAILURE WAS UNDETERMINED. THE CONTACT STATED THAT THE VEHICLE STALLED WITHOUT WARNING, OIL WAS LEAKING FROM THE VEHICLE, AND THE COOLANT WAS NOT IN THE VEHICLE. THE VEHICLE WAS TOWED TO ANOTHER INDEPENDENT MECHANIC WHERE THEY STATED THAT THE OIL PRESSURE NEEDED TO BE REPAIRED, THE VALVE TIMING WAS NOT IN SYNC WITH THE PISTON, AND THE INTAKE CAM SHAFT WAS OVER ADVANCED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURES. THE APPROXIMATE FAILURE MILEAGE WAS 106,000.

TRYING TO FIND OUT ABOUT THE LONG DELAY IN GETTING THE IGNITION PART FOR MY VEHICLE . I CONTACTED MY DEALER FAULKNER GMC OF TREVOSE PA BACK IN APRIL THEY ORDERED THE PART AND AS OF THIS E MAIL HAS NOT RECEIVED THE PART FROM GM. I WOULD LIKE TO KNOW WHY IT IS TAKING SO LONG . I HAVE KEPT MY DRIVING TO A MINIMUM IN THE VEHICLE BUT A 5 MONTHS DELAY IS INEXCUSABLE AS WELL AS DANGEROUS. *TR
