| May 2019 | SERVICE BRAKES | ON 5/28/19 I FILLED MY 2019 GMC SIERRA DENALI AT THE LOCAL GAS STATION. AS USUAL I TURNED THE VEHICLE OFF. AFTER FUELING, I STARTED THE VEHICLE AND BEGAN PULLING OUT OF GAS STATION. UPON EXITING I LOST ALL BRAKING POWER AND THE PEDAL WENT TO THE FLOOR. I WAS GOING APPROX. 5 MPH. I PULLED OVER AND HAD TO STEP ON THE BRAKE PEDAL UNTIL IT WAS ON THE FLOOR WITH EXTREME FORCE. THE CHECK ENGINE LIGHT ALSO APPEARED ON THE DASHBOARD. AT APPROX. 4:41PM I RECIEVED AN ONSTAR EMAIL WITH AN ANTILOCK BRAKE PROBLEM. EMAIL SUGGESTED I TAKE THE VEHICLE FOR SERVICE WITHIN 7 DAYS. I HAD GMC ROADSIDE TOW THE TRUCK FROM MY HOME TO THE NEAREST DEALER(STATEN ISLAND BUICK GMC) I LEASED THE VEHICLE FROM COLEMAN BUICK GMC AND WHEN I CONTACTED THEM I WAS TOLD THEY COULDN'T HELP AND THE DEALER THE TRUCK WAS TOWED TO IS STILL GM. I ALSO CONTACTED GM CUSTOMER SERVICE. RECEIVED A CASE # AND WAITING TO BE CONTACTED. AS PER COLEMAN THE VEHICLE HAS RECALLS FOR A TRAILER BRAKE MODULE AND PARK ASSIST. AS PER SI BUICK GMC THEY COULD NOT FIND ANY COMPUTER CODES. THE HYDRAULIC TEST SHOWED NO ISSUES. THEY CLAIM TO HAVE UPGRADED THE COMPUTER AND THE TRUCK WAS SAFE TO DRIVE AS OF 5/30. THEY WANT TO TEST DRIVE AGAIN ON 5/31 AND I ASSUME I'LL BE ASKED TO PICK UP MY TRUCK. I FIND THIS TO BE UNACCEPTABLE AND A MAJOR SAFETY ISSUE. THANKFULLY I WAS GOING 5MPH WHEN I LOST FULL BRAKING. I WAS TOLD IF THE ISSUE HAPPENS AGAIN TO BRING THE TRUCK BACK IN FOR DIAGNOSTICS AND REPAIR AS NEEDED. THIS SAFETY ISSUE CAN POTENTIALLY CAUSE PHYSICAL INJURY AND OR PROVE TO BE FATAL. DEPENDING ON TECHNOLOGY TO DETERMINE BRAKING CAPACITY IS ABSURD. 2019 GMC SIERRA ALSO HAVE ELECTRICAL PROBLEMS DULY NOTED BY CUSTOMERS. FORUMS ALSO MARK THE SAME BRAKING PROBLEMS HAVE OCCURRED WITH OTHER OWNERS IN DIFFERENT STATES. A RECALL SHOULD BE ISSUED FOR THE SAFETY OF DRIVERS, PASSENGERS AND PEDESTRIANS! LIVES ARE AT RISK AND A RECALL IS NEEDED! | Crash: No Fire: No | 5,051 |

| Apr 2019 | STEERING,ELECTRONIC STABILITY CONTROL (ESC),SERVICE BRAKES | ON APRIL 2, 2019 I PARKED BREFILY FOR ABOUT 30 MINUTES. UPON RE-ENTERING MY 2019 GMC SIERRA TRUCK WITH APPROXIMATELY 4500 MILES AND STARTING THE ENGINE I IMMEDIATELY RECEIVED MULTIPLE WARNING MESSAGES ON MY DASH PANEL. THEY WERE "SERVICE ESC" "SERVICE TRAILER BRAKE", "BRAKE SYSTEM FAILURE" "STEERING ASSIST REDUCED" AND TO DRIVE NO FASTER THAN 62 MPH. PREVIOUSLY PRIOR TO PARKING I HAD NEVER HAD ANY PROBLEMS WHATSOEVER. I WAS IN A LOCATION WHERE I NEEDED TO GO SO I ATTEMPTED TO DRIVE BUT FOUND QUICKLY THAT THE BRAKE PEDEL WENT ALL THE WAY TO THE FLOOR WITH VERY LIMITED OR BASICALLY NO BRAKING. THE STEERING BECAME VERY DIFFICULT WITH NO APPARENT POWER ASSIST. I DROVE IT APPROXIMATELY TWO MILES AND GOT TO A LOCATION WHERE I COULD PARK. I TURNED THE ENGINE OFF AND BACK ON AND THE PROBLEM DID NOT GO AWAY. I TURNED IT OFF AGAIN AND WAITED A COUPLE OF MINUTES AND THEN HEARD AN AUTOMATED COUPLE OF CLUNK SOUNDS FROM THE FRONT.. I STARTED IT UP AND EVERYTHING WAS OKAY EXCEPT THE CHECK ENGINE LIGHT WAS ON AND STAYED ON THE REST OF EVENING. THE NEXT MORNING THE CHECK ENGINE LIGHT WAS STILL ON HOWEVER ABOUT TWENTY MINUTES LATER I NOTICED IT WAS OFF AND EVERYTHING HAS BEEN FINE SINCE. I HAD PLANNED TO TAKE IT TO THE GMC DEALER HOWEVER WITH NO PROBLEM SHOWING NOW AND FROM PAST EXPERIENCE WITH THE DEALERSHIPS I DECIDED THERE WAS NO NEED TO SCHEDULE AN APPOINTMENT UNTIL THE SYMPTOMS COME BACK. I FOUND ON THE INTERNET LATER THAT THERE ARE NUMEROUS INSTANCES WHERE THIS HAS HAPPENED TO MANY OTHER 2019 GMC SIERRA OWNERS. I FEEL THAT THIS IS A EXTREMELY SERIOUS PROBLEM THAT NEEDS IMMEDIATE ATTENTION ESPECIALLY WITH THE NEAR TOTAL BRAKING SYSTEM FAILURE! | Crash: No Fire: No | 4,500 |
