I HAVE A ISSUE WITH MY DASHBOARD CRACKING ALONG THE AIRBAG MODULE DOOR. I BELIEVE IF I WAS OR INVOLVED IN A ACCIDENT AND THE AIR BAGS ARE DEPLOYED THE PIECES OF DASH CAN BECOME FRAGMENTS AND CAUSE EXCESSIVE INJURY AND ALSO COULD DEFLATE THE AIRBAGS UPON EXPANSION. CAUSING MORE INJURY THAN DEEM NECESSARY.

AFTER BEING STOPPED LIKE AT A STOPLIGHT, THEN WHEN IT'S TIME TO ACCELERATE, THE TRUCK HAS A HARD JERK TO IT, AND IT DOESN'T WANT TO DOWN SHIFT. PLUS WHEN RIDING DOWN THE ROAD, THE TRUCK WILL LO JUST SUDDENLY JERK SO BAD THAT IT FEELS LIKE SOMEONE RAN INTO THE BACK OF THE TRUCK. THIS HAS BEEN GOING ON FOR A LONG TIME, AND I HAVE TAKEN IT TO THE DEALERSHIP 4 TIMES AND THEY SAID THEY COULDN'T FIX IT. I EVEN RODE WITH THEM, AND IT DID IT. THEY STILL DIDN'T WANT TO FIX IT.

ABOVE 35MPH I BEGIN TO GET AN EXTREME SHAKE AND VIBRATION. IT GETS MORE AND MORE PRONOUNCED AS I DRIVE. AT 65MPH IS NEARLY UNBEARABLE, AND SHAKES AND VIBRATES VIOLENTLY. IT GIVES ME HEADACHES, AND I CAN FEEL IT IN MY ARMS AS I DRIVE. I FIRST NOTICED IT ABOUT 100 MILES AFTER BUYING THE TRUCK. IT NOW HAPPENS DAILY.

WHILE TRUCK WAS PARKED (ENGINE WAS NOT RUNNING AT ALL), I USED THE KEY FAB REMOTE TO UNLOCK THE TRUCK AND THEN OPEN THE TAILGATE. AT THIS TIME, THE TAILGATE SLAMMED OPEN (VERY FORCEFULLY AND QUICKLY) AND HIT MY SON IN THE CHEST. THIS HAS ALSO HAPPENED WHILE THE TRUCK WAS RUNNING AND IN PARK. AT THAT TIME, I (THE DRIVER) PUSHED THE BUTTON ON THE CENTER DASH TO OPEN THE TAILGATE SO THAT MY YOUNG SON COULD PUT HIS BASEBALL GEAR IN THE BED OF THE TRUCK. AGAIN, THE TAILGATE OPENED VERY QUICKLY AND ABRUPTLY, SLAMMED OPEN, AND THE HEAVY TAILGATE HIT HIM IN HIS BODY. THE TAILGATE IS SUPPOSED TO OPEN SLOWLY AND GRADUALLY, NOT SLAM OPEN. THANKFULLY, MY SON WAS NOT SERIOUSLY INJURED. THE REMOTE CONTROL, SLOW OPENING TAILGATE WAS ONE OF THE SELLING FEATURES OF THE TRUCK, AND NOW THE TAILGATE IS DANGEROUS TO USE AT ALL, ESPECIALLY WHEN CHILDREN ARE AROUND.

THE FIRST ISSUE IS A BLUETOOTH ISSUE. THE PHONE VOLUME GOES SILENT WHEN I GET IN MY VEHICLE. IF I CONNECT TO CAR PLAY, IT WORKS. I HAVE MISSED IMPORTANT CALLS DUE TO THIS ISSUE. THIS STARTED IN JULY OF 2019 AND ITS NOT FIXED YET. GM SAYS IT APPLE. APPLE SAYS ITS GM I DO NOT CARE JUST FIX IT. SECOND SEE BELOW IMAGES. YOU KNOW THE ISSUE. THIS HAPPENED TO ME 3 TIMES. IT STARTED 12-05-2019. THEN AGAIN 12-26-19 . SERVICED . 1-4-2020 AGAIN. 1-18 20 AGAIN AND TO SHOP UNTIL 1-23-2020. THIS TOOK A LOT OF MY TIME TALKING WITH MY DEALER. I UNDERSTAND I AM ONE OF MANY, BUT I DIDN'T SPEND OVER $66,000 TO BUY, LEASE THIS VEHICLE TO HAVE TO WASTE MY TIME. THIS COST ME TIME, MONEY AND HONESTLY EVERY TIME I START THE TRUCK I WONDER IF IT WILL REAPPEAR. I RECEIVED 2 CALLS FRO REPRESENTATIVES, GIANNA AND MICHELLE. I CALLED BACK 3 TIMES, LEFT VOICEMAIL AND HAVE HEARD NOTHING. AT THIS POINT, I AM REQUESTING FOR GM TO END MY LEASE AND I GIVE YOU THIS TRUCK BACK .

ELECTRIC/ELECTRONIC/COMPUTER ISSUES. MOST ISSUES ARE INTERMITTENT, SOME HAPPEN ALL THE TIME.

SECONDARY BLUETOOTH PHONE DOES OUTGOING CALLS THROUGH TRUCKS INFO SYSTEM. HEADS-UP DISPLAY GIVES DOUBLE TURN DIRECTIONS DURING ROUTE GUIDANCE NAV. BLUETOOTH TEXTING DOES NOT WORK. THE FOLLOWING ISSUES HAPPEN FREQUENTLY. TRANSMISSION BANGS/SHUDDERS PERIODICALLY, ACCELERATING, NOT ACCELERATING, SLOWING DOWN, JUST DRIVING, MOSTLY ON LEVEL GRADE. SOMETIMES STRONG ENOUGH TO FEEL LIKE I WAS REAR ENDED, PASSENGERS HAVE JUMPED MANY RADIO MEDIA ISSUES WITH SOUND AND NAV BOOT UP. DURING PARKING MANEUVER AFTER COMING OUT OF REVERSE AND GOING INTO DRIVE, FORWARD CAMERA WOULD COME ON AND THEN SWITCH TO NAV SCREEN WHEN I TOOK MY FOOT OFF THE BRAKE. TO RESOLVE WOULD GO IN REVERSE THEN BACK TO DRIVE AND THE FRONT CAMERA WOULD STAY ON. AFTER VEHICLE START I GO INTO DRIVE AND FRONT CAMERA COMES ON. SOMETIMES IT DOES NOT IN THE EXACT SIMILAR CIRCUMSTANCES. NO INDICATION FROM FORWARD DETECTION SENSORS. AFTER BACKING OUT OF A PARKING SPOT, GOING INTO DRIVE FORWARD CAMERA COMES ON THEN THE WHOLE SCREEN GOES BRIGHT BLUE, AFTER A FEW SECONDS FORWARD CAMERA COMES BACK ON UNTIL I SPEED UP.
