2016 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.

I’ve only had this vehicle for about 2 years now. I purchased it off of Carvana and had 30 days I could’ve returned the vehicle if there was issues. When I first got it, I noticed the vehicles gas pedal would shutter a tad while going up a hill or at a higher speed like on the highway. It would also jolt a little while taking off but when I took it to the dealership they were saying everything is normal and I believed everything was fine since there was no lights on the dash, it was my first time ever buying a car myself, and I had no reason not to trust them. The vehicle is now at a little less than 85,000 miles and I can’t drive it because of how bad it’s jerking, I did a little more research and come to find out this is a huge issue with GMs vehicles transmissions within that years range however my vehicle in particular isn’t on that list. The CTS and i believe even a few ATS Vs were on there but mine is doing the same exact behaviors as they’re describing. If there’s any way you guys can help me out it would honestly be a blessing

The contact owned a 2016 Cadillac ATS. The contact stated while driving 40-50 MPH and entering the expressway, she engaged the turn signal and verified that the road was cleared. The contact stated that while she was making the turn, an 18-wheeler truck suddenly hit the vehicle, causing the vehicle to crash into another vehicle. The contact stated that the vehicle was hit three times and spun onto the median, where the vehicle continued to spin until it hit the fence. The contact stated that her sister was occupying the front passenger's seat at the time of the accident. The air bags failed to deploy. Both the contact and her sister were transported to the hospital by emergency units. The contact stated that she sustained injuries on the left side of her body. The contact sustained severe pain on the left shoulder, left arm, left wrist, lower back, on and the neck down to under the shoulder blade.

Reporting a case for GM recall N182161890. I bought my vehicle in 2022. I was informed that my car had all the recalls completed on that vehicle. My vehicle had exactly what this recall was for happen to it on 10/20/23. After contacting Cadillac, they informed me that this recall was never completed on my vehicle. Cadillac then told me that this recall was expired so it can no longer be completed. They said that the recall expired on 11/30/2020. I was under the impression that recalls do not expire, especially ones that can cause lose of power steering and could lead to collision or injury. Cadillac told me it expired because it was a "Customer Satisfaction Program" recall and not a "Product Safety" recall. I'm confused on how the lose of steering is not a product safety issue. Cadillac is unwilling to fix the recall at this time, even though they have confirmed it had never been completed.
