2016 BUICK REGAL Unknown Or Other Problems

I purchased the buick regal new in Feb 2016. After about two years, it skid on a perfect road surface in a perfect weather, the traction control light and the engine light came on, but disappeared after 30 seconds or so. The problem was scary enough that I brought the car to a neighborhood dealership to see if there was any safety recall for that issue. There was none. The replaced a sensor or something to fix the problem. It has not happened again until two weeks ago. Exactly the same thing happened, skid briefly on a perfect road surface in a perfect weather condition, skid light and the engine light came on, but disappeared after a minute. I brought back the car to the dealership and asked them find the original record for fixing the problem. But, they insisted it was not the same issue, this time it was...

DRIVER INFOTAINMENT CENTER HAS MANY ISSUES, REMAINS BLANK WHILE RADIO IS PLAYING AND CAN BE CONTROLLED BY STEERING WHEEL CONTROLS AND HVAC VIA EXTERNAL BUTTONS. ALSO BACKUP CAMERA INTERMITTENTLY JUMPS THE VIDEO FROM CAMERA BUT NOT THE CGI LINES. THIS MAKES YOU STOP DUE TO REFLEXES THINKING SOMETHING RAN OUT IN THE WAY OF BACKING UP. ON OCCASION THE DISPLAY HAS SHOWN SYSTEM ERROR AND ALSO HVAC CONTROL NOT OPERABLE. ALSO HAVE SEEN THE CGI DIRECTIONAL LINES NOT SHOW UP UNTIL PLACED IN FORWARD GEAR JUST BEFORE THE DISPLAY TURNS OFF THE CAMERA. DEALER AND BUICK HAVE BEEN NOTIFIED AND MECHANIC COULD NOT DUPLICATE THE INTERMITTENT PROBLEM SO THEY WILL NOT REPLACE ANY COMPONENTS YET THIS PROBLEM OCCURS DAILY BETWEEN TRIPS BUT CANNOT BE REPLICATED TO SHOW DEALER. WE HAVE VIDEOS OF THE PROBLEM AND PHOTOS OF THE ERROR MESSAGES. DEALER HAS REPROGRAMMED THE SYSTEM MULTIPLE TIMES NO FIX YET....
