2013 CADILLAC ATS Suspension Problems

2011 Cadillac ATS 3.6, Rear Differential went out, Repairmen has stated that this part is not available anywhere, and that Cadillac should have recalled this in the ATS, because there is a shortage of this part. Due to the inefficiency of the Rear Differential. But, Cadillac would have been out of a lot of money. Without this part, the Cadillac is undrivable.

I was making a left turn and I heard a loud popping noise. I pulled the vehicle into a parking lot. After stopping it would not move. When I put the car in gear I would hear a loud grinding noise coming from the back wheel base. I had the vehicle towed to a repair shop. I was told that the roll pins that connect the axel to the rear differential had come out. I am unable to have the car repaired because there are no rear differentials available in that there is a nationwide back order and no one knows when they will be available. This seems similar to the problem that led to a recall of the 2014-15 Cadillac CTS model. NHTSA Recall No. : 20V-038 https://www.autoblog.com/2020/02/03/cadillac-cts-v-sport-recall/
