Consumer Description

THE DIFFERENTIAL IN MY CAR HAS STARTED TO WHINE AFTER ~11K MILES DESPITE, PERHAPS, THE LEAST ABUSIVE DRIVING THAT IS REASONABLY POSSIBLE, ESPECIALLY CONSIDERING THAT THIS CAR IS A CTS-V. TO SAY I AM DISAPPOINTED WOULD BE AN UNDERSTATEMENT. AFTER A LITTLE BIT OF INVESTIGATION, IT APPEARS THAT GM HAS USED AN UNDER-ENGINEERED PART FOR ITS DIFFERENTIAL FOR REASONS I'M NOT REAL CERTAIN OF. MULTIPLE FAILURES ARE BEING REPORTED ALL ACROSS THE COUNTRY, MANY WITH SIMILAR DRIVING HABITS THAT I HAVE. THE CTS-V DIFFERENTIAL IS A LIMITED SLIP 3.73 APPLICATION AND REQUIRES ~ 7% FRICTION MODIFIED OIL. SUCH FLUID WAS CHANGED SEVERAL THOUSAND MILES AGO AS A PRECAUTIONARY MEASURE AND THE PROPER OIL WAS ADDED. I PLAN ON TAKING MY CAR IN FOR EVALUATION/SERVICE IN THE NEAR FUTURE, BUT I BELIEVE THAT GMS DECISION TO INSTALL A CLEARLY KNOWN "BAD" PART IS WHOLLY EGREGIOUS. *JB
