NHTSA Complaint #11394363 — 2020 GMC SIERRA 1500

AT ABOUT 3500 MILES LIFTERS ON TWO CYLINDERS COLASPED. TOOK TO DEALER THAT DEALER HAD THREE WEEKS BUT FIXED IT. 1500 MILES LATER AT 5036 MILES IT HAPPENED AGAIN ON A DIFFERENT CYLINDER. NUMBER 8. THE FIRST TIME IT WAS 3 AND 5. THE FIRST TIME THE DEALER REPLACED ALL 8 CYLINDERS. SO CYLINDER NUMBER 8 WAS NEW AS WELL. GMC HAS SAID THERE IS NOTHING ELSE THAT CAN BE DONE TO FIX THE ISSUE. THE SECOND DEALER SERVICE MANAGER STATES THAT HE WOULD NOT TRUST IT EITHER TO GO ANY LONG DISTANCE . ALSO STATED THAT THEY HAVE PUT 3 SETS IN TO ONE VEHICLE BEFORE. AS AN ASE MASTER CERTIFIED TECHNICIAN I FIND THIS DISTURBING. I ALSO WAS A GMC,PONTIAC, OLDSMOBILE MASTER TECHNICIAN. THIS IS UNEXCEPTABLE FOR GM TO THINK THIS IS OK TO TAKE PEOPLE'S HARD EARN MONEY AND NOT FIX THERE ISSUES OR MAKE IT RIGHT. I OWNED A 2014,2016,2018 SILVERADO'S THAT HAD NO ISSUES WHAT SO EVER. TO MAKE THINGS WORST GMC ROAD SIDE ASSISTANCE FORGOT ABOUT THE TRUCK BROKE DOWN IN 7 DEGREE WEATHER WITH 35 MILE AN HOUR WINDS. FOR OVER 24 HOURS AND SEVERAL CALLS BACK TO FINALLY GET A SUPERVISOR TO SPEAK TO. TWO DEALERS SAY THAT IT IS UNACCEPTABLE EXCEPT THE CURRENT DEALER THAT IS DEALING DIRECTLY WITH GMC. ANYONE CAN DO A SEARCH ON GM TRUCK LIFTERS COLLAPSING AND YOU IMMEDIATELY OVERWHELMED WITH INFO. IT IS ALSO DISTURBING THAT A DEALERSHIP SERVICE MANAGER SAYS WE COULD PUT A NEW ENGINE IN AND THE SAME THING COULD HAPPEN. THAT TO ME IS POOR QUALITY CONTROL AND POOR CUSTOMER SERVICE. I HAVE ALWAYS BEEN A GM ENTHUSIASTS BUT THIS WILL BE MY LAST ONE. HORRIBLE CUSTOMER SERVICE AND DO NOT BUILD A GOOD PRODUCT OR STAND BEHIND IT. GM SHOULD BE ASHAMED OF THERE FALL FROM GRACE. THIS ALL HAPPENED JUST DRIVING ONCE TO WORK AND ONCE HAULING A ATV ON A TRAILER.
