NHTSA Complaint #11366520 — 2017 BUICK ENVISION

ON AT LEAST 5 DIFFERENT OCCASIONS THE DASH BOARD LIGHTS AND INFOTAINMENT SYSTEM HAVE WENT COMPLETELY BLACK THIS IS AT VARYING SPEEDS FROM 25 MILES TO 60 MILES AND EVEN SITTING AT A STOP LIGHT THIS HAS HAPPENED. WHEN IT DOES HAPPEN ITS ONLY FOR COUPLE SECONDS. THIS HAS ALSO HAPPEN TWICE WHILE MY TEENAGE SON WAS DRIVING AND SCARED HIM QUITE A BIT. MOST RECENTLY WHILE AT A STOP LIGHT I LET MY FOOT OF THE BRAKE AND PUSH GAS I GET A MESSAGE SAYING PARK BRAKE RELEASED THE DOORS UNLOCK THEN LOCK. I TRY TO MOVE THE STEERING WHEEL BUT ITS HARD LIKE IT'S LOCKED I THEN GET MESSAGE SAYING POWER STEERING HAS BEEN REDUCED DRIVE CAREFULLY. THEN A FOLLOWING MESSAGE SAYING ALL WHEEL DRIVE HAS BEEN TURNED OFF. THIS HAS HAPPENED ABOUT 7 OR 8 TIMES RANDOMLY AFTER COMING TO A STOP FOR A RED LIGHT IN WHICH LIGHT TURNS GREEN I TRY TO PROCEED THAN ALL THIS MESSAGES AND WHEEL TIGHTENS AND CAR FEELS LIKE IT STALLS FOR A SECOND.
