Cadillac Cts 2007 rear differential broke was driving on the high way and suddenly lost control of the car. The back wheels locked completely. No apparent trigger. Put on brakes (I was scared I was close to the edge of the overpass), shut off the car and the smoke dissipated. No warning at all; no other damage but quite terrifying. Cadillac was extremely responsive and has replaced the rear differential.

Driving approximately 65 mph on I64 in Virginia when gears locked up and lost all acceleration. Pulled off to the side and could smell a burning sensation, car then would not move. Back wheels locked up and when car attempted to be moved for a tow, entire back end rattled and grinded. Took vehicle to the dealer as it is still under warranty and has only 15K miles, dealer reported that it was an "exploded rear differential." All parts were replaced by dealer, who remarked they had replaced many rear differentials in the past yet has never seen one explode like that before. Luckily, driver remained in control of car and pulled over at the very instant there was a problem otherwise this could have resulted in a catastrophic loss while traveling at a high speed on the interstate.

I own a 2007 Cadillac Cts-V.since purchased the vehicle has been leaking differential fluid from numerous points of rear end assembly.I have taken the vehicle to service 5 times and five times the problem was not corrected.the differential assembly on theses types of Cadillac are very weak and not able to withstand the power of the vehicle. I think this is deffinetly a safety concern and have done much research and found numerous complaints from other Cts-V owners who have had complete differntial failure where the unit has blown up into several peices which may cause loss of control of vehicle.I think something should be done to correct this problem from the manufacturer.in my case they changed numerous seals and gaskets but after driving vehicle home the leaks always reoccur from the unit flexing because its weak
