2018 Chevrolet Silverado 1500

TRANSMISSION PROBLEMS INCLUDING SLIPPING, SHIFTING HARSHNESS, CLUNKING, ESPECIALLY ON DOWNSHIFTS AND SLIPPING WHEN TOWING. CLUNKING NOISE/FEEL WHEN SLOWING DOWN/STOPPING. ESPECIALLY NOTICEABLE ON HILLS, BUT PRESENT ON FLAT AND DOWNHILL ROADS AT SURFACE STREETS AS WELL AS FREEWAYS AND HIGHWAYS. PROBLEM FIRST BROUGHT TO CHEVROLET'S SERVICE DEPT AT 7000 MILES AND TOLD IT'S NORMAL. AGAIN BROUGHT TO SERVICE DEPT ATTENTION AT APPROXIMATELY 12000 MILES AND AGAIN TOLD IT'S NORMAL. PROBLEM CONTINUED TO WORSEN SEVERELY AND AGAIN BROUGHT TO SERVICE DEPT ATTENTION AT APPROXIMATELY 15000 MILES. PROBLEM DIAGNOSED AS FAILING TORQUE CONVERTER. THIS WAS REPLACED. PROBLEM WITH TRANSMISSION CONTINUES AFTER REPLACEMENT AND AT 16197 MILES IT IS NOW BACK AT THE SERVICE DEPT.TRANSMISSION IS THE 6 SPEED AUTOMATIC.

TRUCK WILL LOSE ALL POWER, EVERYTHING WILL SHUT OFF, AND THEN COME RIGHT BACK ON. IT HAS HAPPENED WHILE ACCELERATING INTO TRAFFIC, SLOWING DOWN TURNING RIGHT AND TURNING LEFT, AND WHILE MOVING STRAIGHT AHEAD. IT HAS BEEN IN THE SHOP ONCE FOR THIS SAME ISSUE AND THEY TELL ME THEY CANNOT FIND ANYTHING WRONG WITH IT. THE STABILITRAC WARNING WILL COME ON AND GO OFF AND HAVE HAD STALL WARNING FLASH IN TRAFFIC AT STOP LIGHTS. THIS HAS BEEN GOING ON FOR THE LAST 12,000 MILES AND I HAVE 20,083 MILES ON TRUCK NOW. THE CLOCK AND RADIO RESET. IT SHUTDOWN PULLING INTO TRAFFIC ON A BUSY HIGHWAY AND WAS A VERY DANGEROUS SITUATION. BEEN TRYING TO GET IT INTO DEALERSHIP SINCE 3 WEEKS AGO AND NO LUCK. THIS IS NOT THE ONLY ISSUES WITH THIS TRUCK.

WHILE DRIVING 41-60MPH, THE TRUCK STARTS TO IDLE AS IF THE BRAKES ARE BEING PUSHED ON ONE TIRE AND THE BRAKE PEDALS AND GAS PEDAL TEND TO VIBRATE AS IF IT WERE TO FALL OFF. AFTER AWHILE DOING THAT, THE STABILITY CONTROL LIGHT MESSAGE COMES ON AFTER REACHING THE MIDDLE OF THE COOLANT TEMPERATURE AND THE PROBLEM GOES AWAY. SEEMS LIKE IT DOES IT WHEN IT'S ON LOW TEMPERATURE.

FIRST THE CONTROLS ON THE STEERING WHEEL STOPPED WORKING, WHILE DRIVING ON A NORMAL STREET IN TOWN. THEN THE STABILITRAK SERVICE MESSAGE AND CHECK ENGINE LIGHT CAME ON WHILE DRIVING DOWN THE HIGHWAY. WHEN THE MESSAGE CAME UP THE TRUCK WOULD NO LONGER GO WHEN THE GAS PEDAL WAS PRESSED. PULLED OVER AND TURNED OFF THE STABILITRAK IN ORDER TO MAKE IT HOME AND THE TRUCK SHIFTED VERY HARD INTO EACH GEAR AND ONLY WOULD SHIFT BETWEEN 3000 AND 3500 RPMS.

MY VEHICLE IS HAVING HARD DOWNSHIFTING ISSUES. MAINLY FROM 2 TO 1 AND OCCASIONALLY FROM 3 TO 2. I NOTICE THERE ISNT A RECALL LISTED BUT IT DEFINITELY SEEMS LIKE A SERIOUS ISSUE. THAT COULD POSSIBLE CAUSE DAMAGE LATER ON. I'VE READ ONLINE THAT IT SEEMS TO BE A PRETTY COMMON ISSUE WITH THE SILVERADO 2014-2019. I WOULD LIKE AND EXPLANATION AND FIX PLEASE. CHEVROLET HAS CHECKED AND SAID IT DOESN'T READ AS AN ISSUE ON COMPUTER READING. THANKS

ON 8/17/2020 I STARTED GETTING A SEVERE SHAKING IN THE FRONT END OF MY 2018 CHEVROLET SILVERADO CREW CAB 4X4 LTZ. THINKING THAT I THREW JUST A WHEEL WEIGHT I TOOK IT TO MY PRIORITY CHEVROLET IN CHESAPEAKE VIRGINIA AND FOUND OUT IT HAS A SHUTTER SHAKE AS THE DEALERSHIP CALLED IT. AFTER DOING RESEARCH ON THIS I HAVE FOUND THAT THERE IS A CLASS ACTION LAW SUITE AGAINST GM ON THIS MATTER AND IS A VERY COMMON PROBLEM THAT PEOPLE ARE HAVING FROM YEARS 2014 THRU 2019. I WOULD THINK AFTER ALL THIS INFORMATION ON THIS A RECALL WOULD BE PUT OUT ON THIS.I DO NOT HAVE ANY DOCUMENTATION AT THIS TIME DUE TO IT STILL BEING AT DEALERSHIP FOR REPAIR.THIS HAPPENED WHILE DRIVING ON INTERSTATE 64 EAST BOUND AT A SPEED OF 55 UP TO 65 WHEN PROBLEM OCCURRED.

THE MIDDLE REAR SEATBELT IN THE 2018 SILVERADO CREW CAB HAS A PLASTIC STRAP RETAINER THAT COMES APART EASILY, CAUSING THE SEATBELT TO GET STUCK ON ONE SIDE OR THE OTHER OF THE METAL POSITIONING BAR. THIS HAS HAPPENED WHILE DRIVING AND THE REAR CENTER PASSENGER'S SEATBELT WAS LEFT SLACKED. IT WILL ONLY RETURN ONCE THE SEATBELT STRAP IS MANUALLY CENTERED ON THE METAL POSITIONING BAR. THE CLIPS ON THE PLASTIC PIECE APPEAR TO BE INSUFFICIENT. THE CHEVROLET DEALERSHIP HAS REPLACED THE PLASTIC STRAP RETAINER PIECE ONCE ALREADY AND IT DID NOT CORRECT THE PROBLEM.
