2017 Buick Envision

WHILE DRIVING DOWN INTERSTATES AND HIGHWAYS, THE VEHICLE'S DASHBOARD COMPLETELY SHUTS DOWN. THE RADIO, METERS, DASH DISPLAY, ETC. ALL GO DARK AND TURN OFF FOR A SPAN OF 5-20 SECONDS. THIS HAS HAPPENED MULTIPLE TIMES OVER THE COUPLE YEARS OF OWNERSHIP. THE VEHICLE IS ALWAYS GOING AT LEAST 60 MPH AND, WHILE IT DOESN'T TURN THE ENGINE OFF, IT DOES TURN THE AIR OFF AND, OVERALL, CAUSES A HUGE DISTRACTION FOR THE DRIVER.

ENTIRE DASH CLUSTER HAS GONE OUT. SCREEN COMPLETELY BLACK. INCLUDING AFTER UPDATE IN JUNE 2019. CAR WAS IN MOTION, HAPPENS AT VARIOUS SPEEDS. ALMOST CAUSE AN ACCIDENT. DEALER UNABLE TO SOURCE ISSUE AFTER 3 VISITS TO DATE IN 2019. GM TECHNICIANS UNABLE TO SOLVE ISSUE. GM AND DEALER DOES NOT BELIEVE THIS TO BE SAFETY IS AND KEEPS ALLOWING CAR TO BE RETURNED TO SERVICE.

REAR TAILGATE REQUIRES MANUAL OPERATION TO OPEN, CLOSE, AND LOCK. THE VEHICLE IS EQUIPPED WITH AUTOMATIC LIFT GATE CONTROLS ON THE DRIVER DOOR AND ALSO BY SWIPING FOOT UNDER REAR BUMPER. I HAVE DOCUMENTED FOUR TIMES IN THE PAST MONTH THAT THE TAILGATE WILL NOT OPERATE PROPERLY. EACH TIME HOWEVER THAT I BRING THE VEHICLE TO THE DEALERSHIP, THE TAILGATE WORKS PROPERLY. THE MECHANIC SAID IT IS PROBABLY THE ACTUATOR, BUT UNTIL I CAN BRING IT TO THEM WHEN IT'S NOT WORKING THERE IS NOTHING THEY CAN DO. THERE WAS ONE INSTANCE WERE THE TAILGATE WOULDN'T LOCK EVEN WHEN MANUALLY OPERATED. I HAD TO DRIVE THE VEHICLE WITH THE TAILGATE UNLOCKED AND OPENING WHEN I SLOWED DOWN. THE DEALER SALES PERSONNEL DID A TEMPORARY ADJUSTMENT BY TURNING THE VEHICLE ON AND OFF AND ADJUSTING THE SELECTION KNOB ON THE DRIVER DOOR. YOUR HELP HERE IS APPRECIATED. THE DEALERSHIP IS BEING VERY HELPFUL, BUT CAN ONLY FIX SOMETHING WHEN THEY VERIFY THAT THE ITEM NEEDS REPAIR.

INSTRUMENT CLUSTER LIGHTS GO OUT WHILE DRIVING ( #PIC6333C ). AS ME ARE DRIVING THE INSTRUMENT PLANAL GO BLANK FOR A FEW SECONDS TO A MINUTE, IT IS A DRIVING HASARD AND CAN COUSE AND ACSIDENT. I BUILT AN ALARM SYSTE FOR YOU ( 1980'S ) THAT HAD A LIKE PROBLEM, IT TURN OUT TO BE THE CLOCK REWIND MOTOR SPIKING THE COMPUTER & RE-BOOTING THE COMPUTER IT NEED A FIX NOW

COMPUTER SCREEN DISPLAY FREQUENTLY GOES VERY DIM AND SOMETIMES COMPLETELY OUT SEVERAL TIMES THERE HAS BEEN NO DISPLAY SHOWING WHEN WE WERE BACKING UP PLUS THE WARNING BEEPER DIDN'T COME ON. WE HAVE HAD 2 MINOR ACCIDENTS WHEN WE WERE BACKING UP BECAUSE OF THE FAILURE OF THE COMPUTER SCREEN AND WARNING BEEPER. I HAVE COMPLAINED TO OUR DEALERSHIP HOLM AUTOMOTIVE IN ABILENE , KS FOR AT LEAST 2 YEARS AND THEY DO NOT SEEM TO THINK IT IS A PROBLEM. I HAVE MANY PHOTOS AND VIDEOS PLUS A HANDWRITTEN LOG OF THIS ISSUE. I HAVE ALSO BEEN IN CONTACT WITH BUICK.

WHEN VEHICLE DOES AUTOMATIC SOFTWARE UPDATES FROM GM, IT "BLOWS UP" THE PERSONALIZATION MENU. I AM IN PHYSICAL THERAPY NOW FROM CAR SEAT THAT AUTOMATICALLY WENT TO POSITION 1 WHEN I OPENED CAR DOOR. EASY EXIT HAD BEEN TURNED ON BY UPDATE. I HAD IT TURNED OFF BECAUSE IT NEVER WORKED RIGHT WITH MEMORY SEATS. NOW AFTER ANOTHER UPDATE AND MENU WAS SKEWED AGAIN. EASY EXIT TURNED BACK ON AS WELL AS SEAT HEATERS ON START UP. BOTH HAD BEEN TURNED OFF IN MENU.
