Suspension Problems of Cadillac ATS

My 2016 Cadillac Ats coupe has a serious repeating safety defect. The vehicle violently shakes, vibrates, and becomes unstable while driving. This happened twice. Both times the rear bolts came out except one. Both mechanics who inspected it said they have never seen this before. The first time, I paid $4,000 out of pocket at another shop. The problem happened again, proving this is a manufacturing defect. My axp diagnostic on November 4, 2025 confirms major rear differential/axle issues. The vehicle is unsafe and undrivable. One mechanic told me do not drive it. Cadillac told me the opposite — “safe to pick up” — even though they did no real diagnostic. Cadillac refused to give anything in writing, refused a loaner, and ignored multiple emails. A Cadillac representative told me they reviewed the previous calls, meaning they know the full history. They still refused to fix the dangerous defect. I have paid over $33k, paid $4k for the first repair, still owe $7k, and Cadillac now wants another $7k for the same issue. This is a major safety risk to me and other drivers.

My ball joints on both sides were completely gone, my struts have given out repaired all at the same time, because of those things going out it completely ruined my tires to where they squeak down the road. Both differentials are leaking and my transmission shutters, I also had to replace my water pump that was leaking cooling everywhere.

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. . Read more...
