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.

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.

WHILE DRIVING ON THE FREEWAY, A CAR WAS MERGING INTO MY LANE. I QUICKLY TURNED INTO THE NEXT AVAILABLE LANE AS IT WAS EMPTY, AND WHEN I TURNED THE STEERING WHEEL SLIGHTLY TO THE LEFT, IT OVERCOMPENSATED AND VIOLENTLY TURNED THE STEERING WHEEL TO THE LEFT, LEADING TO THE CAR SPINNING OUT ON THE FREEWAY. IT WAS DIFFICULT TO STRAIGHTEN THE WHEEL AT THAT POINT, UNTIL IT OVERCOMPENSATED TO THE RIGHT CAUSING ME TO SPIN OUT SOME MORE. THIS LED TO AN ACCIDENT, AND IT WAS A MIRACLE NO ONE WAS KILLED. DURING THE TIME OF THIS ACCIDENT, THE ROAD WAS IN GOOD SHAPE, VISIBILITY WAS GOOD, THE WEATHER WAS GOOD, IT WAS AROUND 60 DEGREES OUTSIDE, I HAD JUST GOT ON TO THE FREEWAY, AND WAS TRAVELLING AROUND 60 MPH WHEN THIS HAPPENED (I.E. NO SPEEDING), AND I WAS DRIVING WITH MY LEFT ARM (IT IS A MANUAL, AND MY RIGHT HAND WAS NOT ON THE STEERING WHEEL AT THE TIME) AND DUE TO THE POSITIONING (MY LEFT ARM RESTING ON THE ARMREST), IT WOULD HAVE BEEN IMPOSSIBLE FOR ME TO HAVE TURNED THE STEERING WHEEL ENOUGH TO HAVE SPUN OUT.
