What 35 owners told NHTSA about the 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.

WHEN OPERATING MY VEHICLE INTO DRIVE MANY TIMES WHEN TURNING THE FRONT WHEELS THE CAR LOOSE IT POWER AND STALLS. THIS CAN BE VERY DANGEROUS WHEN TURNING VEHICLE INTO OTHER CROSS SECTIONS OR SMIPLY TURNING. PLEASE LOOK INTO THIS BEFORE SOMETHING SERIOUS HAPPENHIS. THIS INCIDENT OCCURS WHEN STATIONARY OR MOVING FORWARD SLOWLY. I WAS MOVING FORWARD OUT OF MY DRIVEWAY AND INTO ON GOING TRAFFIC. LUCKLY I WAS ABLE TO BAGBACK INTO DRIVEWAY .

WE BOUGHT A USED 2016 ATS WITH 14,000 MILES. WITHIN 2 YEARS, WE HAVE HAD 4 CRACKED CADILLAC WHEELS. WE ALSO HAVE RUN FLAT TIRES, FACTORY INSTALLED. DRIVING UNDER NORMAL CONDITIONS, POT HOLES AND SEAMS IN ASPHALT SEEM TO BE WHAT CAUSED OF CRACKED RIMS. I SUSPECTED A DEFECTIVE ISSUE AFTER 2ND CRACKED WHEEL. I ASKED AT LOCAL DEALERSHIP ABOUT A RECALL AND THEY SAID THEY DIDN'T SEE ONE. I SEE A NUMBER OF COMPLAINTS ONLINE AND FINALLY FOUND A COMPLAINT THROUGH CARCOMPLAINTS.COM THAT WAS NOTED ON NHTSA. THIS IS A KNOWN ISSUE, FACTORY DEFECT AT CANNON CADILLAC IN LAKELAND, FL. IF DRIVEN ON RUN FLATS APPROX 15 MILES TO REPAIR FACILITY, TIRES CAN ALSO BE DAMAGED AND HAVE TO BE REPLACED WHICH WAS MY SITUATION. MY LAST WHEEL PURCHASED LASTED ME 1 YR, 3 WEEKS AND CRACKED BECAUSE OF SEAM IN ASPHALT ON THE FREEWAY. THIS NEEDS TO BE A RECALL. I NOW HAVE 35K MILES AND I'M LOOKING AT THE EXPENSE OF REPLACING ALL 4 WHEELS DUE TO CADILLAC STANDING BEHIND THIS DEFECTIVE WHEEL

ALL 4 RIMS ARE CRACKING AND CAUSING AIR TO LEAK FROM THE TIRES. CANNON CADILLAC IN LAKELAND FL., HAS STATED THESE RIMS ARE A FACTORY DEFECT, BUT HAVE DENIED THE CLAIM TO REPLACE ALL THE RIMS WITH AN ACTIVE 2 YEAR WARRANTY STILL IN EFFECT. I ONLY NOTICED THIS PROBLEM ONCE I HAD JUST PURCHASED A NEW TIRE AND SEEN THAT THE AIR PRESSURE WAS LOW ON THE TIRE. ONCE I TOOK MY CAR TO THE TIRE SHOP, THE TIRE TECHS INFORMED ME THE RIMS WHERE DEFECTIVE, AT THAT MOMENT I MADE A APPOINTMENT AT CANNON CADILLAC. THE PROBLEM IS STILL NOT RESOLVED
