Summary
13313 - SPECIAL COVERAGE. SOME VEHICLES, EQUIPPED WITH A 6.2L V8 ENGINE (LSA), MAY HAVE A CONDITION WHERE THE ENGINEÂ’S SUPERCHARGER MAY NOT FUNCTION AS DESIGNED. IF THIS WERE TO HAPPEN, THE SUPERCHARGER MAY DEVELOP A NOTICEABLE RATTLE NOISE AT IDLE. THE NOISE WILL TYPICALLY GO AWAY WHEN THE ENGINE RPM IS RAISED SLIGHTLY ABOVE IDLE. HOWEVER, IF LEFT UNCORRECTED, THE PROBLEM, OVER TIME, MAY LEAD TO CONTAMINATION OF THE LUBRICATING GREASE AND CAUSE THE BEARING TO SQUEAL. IF LEFT UNADDRESSED, THE BEARING MAY OVERHEAT AND CAN CAUSE ENGINE SEIZURE OR A NO-START CONDITION. DEALERS ARE TO REPLACE THE SUPERCHARGER.
