2020 Cadillac CT6 Complaint Log

The vehicle was shifting harshly and my wheels were experiencing lock up while in motion which was very dangerous. I experienced this on the parkway as well as streets and almost had a few accidents due to this problem. I drive my wife and children in this vehicle. Our safety and lives were put at risk. There were no warning lamps to advise of troubles. I also have some computer problems that are supposed to be addressed. Gm dealer has had my car for four months and have tried to replace valve four times and all four times the part they received was defective and unsuccessful. I have made many calls to GM and they are giving me the run around. Now they want to replace the entire transmission but wanted to use aftermarket part which more than likely is also defective. They are having a hard time obtaining a new transmission and also advised me I would be responsible for the cost of this replacement when they get a new transmission. At this point I am not willing to risk mine or my families life by driving this car after they try to replace transmission. I’m also not willing or able to pay for this repair that was no fault of mine. I am not sure how to proceed in getting them to replace entire vehicle but that is the safest option at this point.

CALLS, EMAILS, POSTS TO CADILLAC AND GENERAL MOTORS GO UNANSWERED. DEALER TELLS ME CADILLAC ENGINEERS FROM CORPORATE COME AND GO WITH NO SOLUTION. I'VE MADE 2 PAYMENTS TO DATE WITHOUT MY CAR.

ON FRIDAY, NOVEMBER 13, 2020 I WAS STOPPED AT A STOPLIGHT IN MARYSVILLE, OHIO. IT APPEARED THAT TRAFFIC STARTED TO MOVE, SO I TOOK MY FOOT OFF THE BRAKE. ALMOST IMMEDIATELY THE EMERGENCY BRAKING FEATURE ENGAGED. WHILE THIS TENDS TO STARTLE YOU BECAUSE IT IS SO ABRUPT, ALMOST LIKE A HEAD-ON COLLISION, I PRESSED ON THE BRAKE. THE BRAKE DID NOT STOP THE CAR. IT WAS SIMILAR TO WHEN ANTI-LOCK BRAKING IS ENGAGED. THE BRAKES FELT LIKE THEY WERE PULSATING, SO THE CAR CONTINUED TO MOVE FORWARD UNTIL IT PRESSED UP AGAINST THE CAR IN FRONT OF ME. I HAVE HAD SOME INSTANCES WHERE WHEN BACKING UP, IN A COMPLETELY EMPTY PARKING LOT OR STREET AND THE CAR WILL BRAKE ON ITS OWN. THERE ARE NO POSTS, TREES OR ANY OBJECTS LIKE THAT ANYWHERE NEARBY TO TRIGGER THE BRAKING. THE MARYSVILLE (OHIO) POLICE DEPARTMENT RESPONDED TO THE ACCIDENT. THE FILE NUMBER FOR THE POLICE REPORT IS 20.01993. I WAS NOT CITED BECAUSE I WAS IN ESSENCE UNABLE TO STOP THE CAR. THERE WAS PLENTY OF TIME TO STOP THE CAR AS I DON'T BELIEVE I PRESSED THE ACCELERATOR AT ALL. THE CAR CURRENTLY HAS A WARNING APPEARING THAT INDICATES DRIVER ASSIST SYSTEM NEEDS SERVICE. I'M NOT SURE IT'S SAFE TO OPERATE THIS VEHICLE SINCE THIS HAPPENED WHILE IN TRAFFIC.

CAR WAS ACQUIRED IN FEBRUARY AND SCRAPING NOISE IN FRONT BRAKES WAS NOTICED IN MAY. WAITED TO SEE IF THE NOISE WOULD GO AWAY BY ITSELF BUT BECAME LOUDER AND TOOK TO CADILLAC DEALER, MILLER CADILLAC IN ELLICOTT CITY MD TELEPHONE 410-750-1100 ON JULY 30. I WAS TOLD THE MECHANIC COULD HEAR THE NOISE BUT COULD NOT IDENTIFY THE SOURCE. HE CALLED GM AND THEY TOLD HIM THERE WAS TECH BULLETIN #PIC6290C INSTRUCTING THE MECHANIC TO TELL CUSTOMER THE NOISE IS NORMAL DOES NOT AFFECT SAFETY OR RELIABILITY OF THE CAR BUT WOULD NOT TELL THE MECHANIC THE CAUSE OF THE NOISE, WHICH IS GETTING WORSE! HOWEVER THE TECH BULLETIN STATES THE CAUSE WAS DETECTED AND CORRECTED ON OCTOBER 30, 2017! THE ISSUE OBVIOUSLY IS NOT CORRECTED AND IS NOT GOING AWAY. I AM CONCERNED THE CAR IS NOT SAFE TO DRIVE ESPECIALLY SINCE GM WOULD NOT TELL THE TECHNICIAN THE CAUSE SO I CAN MONITOR IT. THE BRAKE NOISE OCCURS ON ALL ROADWAYS WHETHER FAST OR SLOW WHETHER TURNING OR STRAIGHT AS CONFIRMED BY THE LOCAL MECHANIC. WHY WON'T GM INFORM OWNERS AND MECHANIC SO THEY CAN ASSESS THE PROBLEM AND UNDERTSAND THE DRIVING RISK?
