WHILE IN MOTION- BLIND SPOT SENSORS TURN ON WHEN THEY SHOULD NOT AND VICE VERSA. TRACTION CONTROL HAS FAILED MULTIPLE TIMES WHILE DRIVING. PREDICTIVE BRAKING HAS ACTIVATED IMPROPERLY MULTIPLE TIMES WHILE DRIVING. CAMERAS WENT OUT AND THEN BATTERY COMPLETELY DIED. WAS TOLD FIXING BATTERY WOULD FIX VEHICLE. THIS HAS PROVEN TO BE UNTRUE. VEHICLE IS CURRENTLY IN FOR SERVICE FOR THIRD TIME. REMAINS UNDER WARRANTY, AS I HAVE HAD IT THREE MONTHS. MOST RECENT DATE HAS BEEN USED BUT I'VE HAD PROBLEMS SINCE LITERALLY THE FIRST FULL DAY I HAVE HAD IT.

TWO DAYS AFTER PURCHASING A NEW 2020 GMC ACADIA I GET AN ERROR ON THE DISPLAY "SD CARD REMOVED" ALONG WITH VARIOUS OTHER ERROR MESSAGES. DEALER TALKS TO GMC TECH LINE AND THEY ADVISE TO REPLACE RADIO. RADIO WAS REPLACED AND ERRORS BEGAN SAME DAY I PICKED IT UP. DEALER IS REPLACING RADIO AGAIN, BUT UNSURE IF THIS WILL FIX THE ISSUE. THE VEHICLE DOES NOT WORK AS INTENDED AS WHEN YOU PRESS THE NAV BUTTON VARIOUS ERROR MESSAGES POP UP AND NAVIGATION DOES NOT WORK.

pre-purchase inspection list. Back to the
