When using adaptive cruise control, this vehicle will allow you to get close to the vehicle in front of you and aggressively apply brakes which throws you forward. The dealer has looked at this vehicle several times for this issue, changed several sensors but the problem still still exists. Because of this issue I cannot use my Adaptive Cruise Control.
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. BUICK WAS OF ZERO HELP ON THIS LEMON OF A PROBLEM AND REMINDED US THE LEMON LAW DOES NOT APPLY TO ACCESSORIES SUCH AS THIS BACKUP CAMERA. LANE CHANGE AND COLLISION DETECTION ALSO HAVE ISSUES OF FALSE REPORTING BUT NO SOLUTION EITHER. STAY AWAY FROM THIS SYSTEM AS IT IS FLAWED AND NO HELP FROM BUICK OR DEALER. DEALER ACTUALLY SUGGEST TAKING THE ISSUE TO ANOTHER DEALER - WOW VERY NICE AFTER SALE SUPPORT.
