NHTSA Complaint #11492119 — 2014 CADILLAC CTS

General Motor's design oversights irreversibly damaged the rear differential carrier of my 2014 Cadillac CTS4 around 75,000 to 80,000 miles. Unfortunately, there is no prior indication of the rear differential carrier assembly leaking fluid or damaging the bearing. Only after the problem occurs, the rear differential assembly starts to make a whining sound that can be heard in the cabin of the vehicle. Unfortunately, the whining sound is a clear indicator that the rear differential assembly is damaged irreversibly. The lack of differential fluid in rear differential carrier assembly can lead to a catastrophic failures. The complete failure of the rear differential assembly would result in internal gears seizing up and locking of the rear wheels. Likewise, there is no prior indicators of when the rear wheels will seize up. On highways speeds, this problem can create dangerous and even life threating conditions to the occupants of the vehicle as well as the other motorists sharing the road.
