2019 Cadillac Cts

The backup camera grid on our 2019 vehicle disappears most of the time when we start in reverse after turning on the engine. We have taken our vehicle into local Cadillac dealership service departments over the past 3 years and they have replaced cables, backup camera, radio equipment, interface screen, etc. with no resolution. This issue with the backup camera grid also seems to be tied to a problem with loading profiles upon startup, radio issues, etc. We are writing to NHTSA because we feel that the backup camera grid disappearing is a safety issue.

My 2019 CTS Cadillac CUE screen shattered for no reason. I was not driving the car. I went out to the car on Thursday, May 27, 2021 and the screen had shattered over night. The system is still working but it is hard to see the screen. The car is leased and only has 20,586 miles. I have only had it 2 years and 5 months. Is this my responsibility to repair or is it covered by warranty?

I LEASED A CADILLAC 2019 CTS IN DECEMBER 2018. THE CAR'S ENGINE ACCELERATES SPORADICALLY ON ITS OWN. IT HAPPENED TO ME APPROXIMATELY 10 TIMES WHILE DRIVING AT VERY LOW SPEED, DURING STOP AND GO TRAFFIC AND AS I WAS ENTERING A PARKING SPOT. THREE SUCH EVENTS OCCURRED WITHIN TEN MINUTES WHILE INCHING MY WAY TO MERGE AND ENTER THE QUEEN'S MIDTOWN TUNNEL IN NY. EACH TIME I MANAGED TO STOP THE CAR BY LEANING VERY HEAVILY ON THE BRAKE PEDAL AND MOVING THE TRANSMISSION INTO THE NEUTRAL POSITION. THE DEALER UNSUCCESSFULLY TRIED TO DETERMINE THE CAUSE OF THE PROBLEM, AND THE CAR WAS IN HIS SHOP FOUR TIMES FOR OVER 20 DAYS. CADILLAC CLAIMS THAT THEY UNAWARE OF ANY SUDDEN ENGINE ACCELERATION PROBLEM. THE LATEST PROPOSAL THAT CADILLAC OFFERED IS TO INSTALL A DIAGNOSTIC DEVICE IN THE CAR WITH THE HOPE THAT THE FAULT WILL SHOW UP. IN THE MEANWHILE CADILLAC EXPECTS ME TO DRIVE THE CAR, ENDANGERING MYSELF, INNOCENT PEDESTRIANS AND OTHER FELLOW DRIVERS.
