2020 Cadillac CT5 other reported problems

UNKNOWN OR OTHER

The left passenger door will not open manually nor with key fob. It has caused me to not allow back seat passengers including grand children for fear if necessary to get out in an emergency and I am left to wonder if the driver door will go into lock position during a collision and that would be life threatening. I tried holding the lock and unlock at the same time for 3sec and that didn’t work. The dealership said it would cost around $800 or more to take the door off and try to find the problem and I would probably have to get a new door and try to match the paint. I really need help with this issue because I have less than 20,000 miles on my car. I have seen online that there’re many people dealing with this problem being it the back doors and some the front. These cars cost the customers a lot of money when purchasing them. I would greatly appreciate the issue being reviewed for recall repairs. Thanks

There is some type of mechanical or electrical malfunction with the door locking system. I can not unlock or enter the car using the fan or by any mechanism from outside the car. This has left my fiance & infant trapped in the car. My fiance has to reach over and manually open the driver side door from inside the vehicle. However, I can no longer drive with only my infant in the car for fear she will be trapped inside.

The rear passenger driver side outside door handle stopped working about 3 days ago. I have three small grandchildren and if there is an accident or any other emergency I cannot open the back door to get them or anyone out of the vehicle to safety, which can lead to bodily harm or worse. I have already had the driver outside door handle replaced on March 18 2025 for the same problem. There should be a recall on the door handles to prevent the chance of bodily harm upon anyone. Also, to prevent this from happening again, the door handles could possibly be replaced with regular door handles. Thank you

While key FOB is operational, next to car door and under moderate temperature conditions, the exterior door handle(s) wont open the car door. The doors freeze, remain latched in place from the outside. The interior door handle on the same door remains operational. This makes it difficult to get into the vehicle to remove people from inside the car should dangerous conditions be present while they are unable to operate the interior handle themselves and/or its difficult to enter the vehicle for safety should dangerous conditions be present outside the vehicle. The doors are jammed, we cant get to you!! There are reports of this happening to all four doors. The dealership says the exterior door handle must be replaced for the door to open from the outside again and it is uncertain if the replacement handle has the defect corrected or not. The latch freeze could occur again, anytime unless the replacement is improved. My vehicle had only 8500 miles on it and the exterior handle failed on the front drivers side. How many times will this condition repeat itself without warning during the lifetime of the car. CadillacForum has discussion on the matter including how some with the problem are disassembling the part and “repairing” the handle defect from the inside. This unnecessary risk could develop into an event that contributed to injuries. A reliable part must be installed asap though many cannot afford the $480 expense to replace it at the dealership. I had a 2000 Cadillac CTS for 20 years and didn’t have a problem with doors locking up from the outside - door handles not responding to efforts to open the door with a correct and operational key fob present.

For no apparent reason my vehicle is shifting itself into Neutral while driving. The car will suddenly completely slow down to a stop and in order to restart the car, I have to put it in park. It doesn't matter what speed or the road condition, it simply comes to a slow stop because it is no longer in driving mode, it has shifted itself into Neutral. The recall has been serviced and after more than 10 days of being in 2 different Cadillac service centers, I am advised they are unable to simulate the issue, thus the issue is not resolved. It is most definitely a safety issue because the vehicle will just stop moving with the flow of traffic. My concern is being rear-ended or having any type of accident since the car abruptly stops without warning.

In reverse infotainment display instead of showing backup cameras, shows a blue screen with a camera error msg. Has occurred since vehicle was new. As it becomes more frequent, we've taken it to the dealer and they serviced it (keeping the car for 2 weeks each time). Upon return it does it occasionally again. Ongoing for 3+ years with no resolution.

Cameras not displaying. Backup or surround. Instead, we get a blue screen with message "service camera system). This has happened every other day or so since purchased new in March 2020. In May 2021 it would continually occur (never function correctly). Dealer had it for 2 weeks replacing different components. The radio, the video processing unit, a communication harness, 2 cameras. Finally got it back to us where it would once again work 80% of the time. Then in Feb 2023 it would continually occur again (always blue screen). Dealer had it for 2 1/2 weeks. Replaced again multiple components this time at the direction of GM corporate techs and a field engineer. Replaced coaxs, cameras, video processing unit. Finally got it back to us where it would once again work 80% of the time. Now just 5 months later, it's continually occuring again.

PURCHASED MY 2020 CT5 IN APRIL 2020. SINCE THEN THE VEHICLE HAS BEEN AT THE DEALERSHIP 5 TIMES FOR THE SAME SERVICE DRIVER ASSIST AND FORWARD COLLISION SYSTEM UNAVAILABLE. GM HAS DISPATCHED A SENIOR ADVISOR TO TEST THE VEHICLE AND EVEN LEFT A CODE READER IN THE VEHICLE TO TRACK ITS PERFORMANCE. MESSAGES CAME ON AGAIN. I RECORDED IT AS INSTRUCTED AND THE DEVICE WAS SENT BACK TO THE GM ENGINEERS. IT HAS BEEN OVER A MONTH TODAY 18 SEPTEMBER AND STILL NO UPDATE AS TO WHAT'S WRONG WITH THIS CAR. THEY'VE REPLACED AND REINSTALLED CAMERAS AND DEVICES AND IT STILL DIDN'T FIX THE ISSUE. I GET A CALL TODAY FROM THE DEALERSHIP SAYING THE RECALL CAME OUT. I'M EXTREMELY FRUSTRATED AND I KNOW THEY STILL CAN'T FIX THE ISSUE AFTER MY CAR HAS BEEN THE FIRST CASE AND GUINEA PIG OF RESEARCH. THIS HAS BEEN GOING ON SINCE DATE OF PURCHASE. IT'S INTERMITTENT AND AT ANY TIME OF DAY

WHEN THE VEHICLE IS TRAVELING OVER 50 MPH, AND TAKES SWEEPING TURNS / GRADUAL BENDS ON THE HIGHWAY, IT BECOMES APPARENT THAT TURNING RIGHT IS MUCH HARDER THAN TURNING LEFT. THE STEERING WHEEL IS MUCH STIFFER AND FEELS HEAVIER WHEN MAKING RIGHT TURNS AT SPEED, ALMOST LIKE IT'S PERMANENTLY STUCK IN SPORT MODE WHEN THE WHEEL IS TURNED RIGHT. IT IS CONSTANTLY FIGHTING TO GET BACK TO CENTER WHEN TAKING THOSE RIGHT TURNS AT SPEED. LEFT TURNS ARE FINE. ON TWO OCCASIONS, THE WHEEL SUDDENLY AND VIOLENTLY JERKED LEFT, TRYING TO GET BACK TO CENTER AS I WAS IN THE MIDDLE OF A TURN/GRADUAL BEND ON THE HIGHWAY. I ALMOST CRASHED INTO THE MEDIAN, AND THE OTHER TWO TIMES, ALMOST RAN SIDEWAYS INTO THE CARS TO MY LEFT. THE DEALER "CANNOT DUPLICATE" HAS NOT CHECKED ALIGNMENT, OR TAKEN OTHER STEPS TO INVESTIGATE. I BOUGHT THE CAR NEW, AND HAVE OWNED IT FOR LESS THAN TWO WEEKS.
