When vehicle was purchased new there was a slight bearing wear noise at the front driver side, which grew louder with years. Noise synchronized with tire rolling rpm. Replacing (my self) front trans axle, the brake pads, shaving rotors, & wheel hub bearing did not fix noise. Next; Dealer shop reported that the AWD front transfer case (differential) had a bad bearing AND that this was a common problem with the model car. $1600 repair bill.

Fuel system
Filed Aug 7, 2026
During refueling the gas station pumping nozzle would shut off indicating a full gasoline fuel tank; but, the dash board fuel gage indicated the fuel was not full. Had to dribble in fuel to fill. Dealer Mechanic found: Crash roll over gasoline vent safety valve was stuck in the crashed roll over cut off state. No gas tank ventilation. This caused back pressure in car gasoline tank to shut off gas station filler nozzle as though the car was full . Entire gas tank had to be replaced. Still under warranty.

Front differential case ripped in half and separated from the ring gear. The broken chunk of differential case and pinion was still attached to the driveshaft while coming to an abrupt stop. Damage done within driveshaft tunnel. No warning, no vibration, no cause for concern, just catastrophic failure. Differential and propeller shaft were replaced by an independent mechanic. Cadillac has not been notified as of today, receipt for repair available upon request.

The brake makes a rattling and metal grinding sound, the dealership said nothing is wrong with the brakes, still problematic. The transmission shifts too hard. Dealer said nothing wrong. Yet cat kicks too hard.

ON MAR 1, 2021 WHILE DRIVING SUPER CRUISE MODE, MY CAR JERKED VIOLENTLY TO THE LEFT ALMOST STRIKING ANOTHER CAR. I WAS ON THE FL TURNPIKE ABOUT 20 MILES NORTH OF ORLANDO HEADING SOUTH. THE HIGHWAY WAS INCREASING FROM 2 LANE TO 3 LANE SOUTHBOUND AND I WAS IN THE RIGHT LANE. WHEN I ENTERED THE LANE TRANSITION, THE CAR DRIFTED RIGHT . AS THE CAR CAME UPON THE NEW WHITE LINE THE CAR ABOUT CENTERED IT. THE CAR TURNED HARD LEFT, AND TURNED OFF SUPER CRUISE. FORTUNATELY, I WAS ABLE TO GRAB THE STEERING WHEEL AND CORRECT THE TURN. WE DID NOT CRASH, BUT IT WAS MOST UNSETTLING.
