NHTSA Complaint #10150962 — 2005 CADILLAC CTS

I HAVE A 2005 CADILLAC CTSV WITH A FAULTY REAR UNDER-ENGINEERED REAR CARRIER UNIT THAT SUPPORTS THE REAR DIFFERENTIAL. IT IS LEAKING. CADILLAC HAS REPLACED THESE UNITS WITH THE SAME FAULTY UNDER-ENGINEERED UNITS MANUFACTURED BY GETRAG WITH 2006 UNITS. THIS SOLUTION HAS BEEN NOTHING MORE THAN A BAND-AID AND THE RESULT OF THE LEAKING IS FAULTY ENGINEERING AS DETERMINED BY SEVERAL HIGHLY RESPECTED ENGINEERING COMPANIES SUCH AS LINGENFELTER AND KATECH THAT GM DOES THERE ACTUAL OUTSOURCING TO. I AM VERY CONCERNED TO DRIVE THIS VEHICLE OUT OF FEAR THAT THE REAR END WILL FAIL AND CAUSE ME TO LOSE CONTROL OF THE VEHICLE AND CAUSE PROPERTY DAMAGE AND POSSIBLE FATAL BODILY INJURY. RATHER THAN CADILLAC ISSUING A RECALL TO REPLACE THIS UNIT WITH A PROPERLY ENGINEERED UNIT TO SUPPORT THE REAR WHEEL TORQUE THAT IS GENERATED BY THIS VEHICLE; THEY HAVE INSTEAD HID BEHIND A TECHNICAL SERVICE BULLETIN AND HANDLE THESE CASES ON A CASE BY CASE BASIS. I REMAIN HOPEFUL THAT YOU WILL TAKE ACTION BEFORE WE ARE DEALING WITH ANOTHER FIRESTONE TIRE ISSUE AS CADILLAC WAS MADE AWARE BY GETRAG THAT THIS REAR CARRIER DIFFERENTIAL WAS NOT "UP TO PAR" WITH THE ENGINE THAT THEY INSTALLED IN THE 2004 AND 2005 CADILLAC CTSV. *JB
