2017 Chevrolet Silverado

WHEN AT HIGHWAY SPEEDS (ANYWHERE BETWEEN 40-75) THERE IS A VERY NOTICEABLE SHAKING WHEN ENGINE IS UNDER LIGHT LOAD (JUST KEEPING SPEED). I HAVE TAKEN IN TO CHEVY DEALERSHIP AND THEY CHANGED THE TRANSMISSION FLUID AND THAT WORKED FOR A COUPLE THOUSAND MILES. NOT THE "CHEVY SHAKE" IS BACK AT FULL FORCE. UPON CALLING CHEVY, THEY CLAIM TO KNOW THAT THEIR TRUCKS DO THIS, BUT SAY THERE IS NOT A FIX TO SOLVE THE ISSUE. THEY CLAIM THEY HAVE NO CLUE WHERE IT'S COMING FROM, BUT SHOULD NOT BE A SAFETY HAZARD. MY QUESTION IS, IF YOU DO NOT KNOW WHAT IT IS, HOW CAN THEY SAY IT'S NOT A SAFETY HAZARD. I AM SO AFRAID THAT MY TRUCK IS GOING TO BREAK DOWN AND IT'S NOT EVEN TWO YEARS OLD. I HAVE READ THE THOUSANDS OF COMPLAINTS ONLINE WITH PEOPLE HAVING THE EXACT SAME ISSUE, SINCE THE 2014 MODEL. THEY HAVE HAD ENOUGH TIME TO FIGURE THIS OUT AND SHOULD BE HELD ACCOUNTABLE.

8 SPEED TRANSMISSION CLUNKS WHEN SHIFTING INTO 2 GEAR AND AT TIMES FEELS LIKE YOU GOT REAR ENDED. WHEN IT DOWN SHIFTS INTO THE LOWER GEARS IT'S ALSO CLUNKS AND IS NOT SMOOTH. THIS IS HAPPENING WHEN GOING AT SLOW SPEEDS AND IS WORSE AFTER A COLD START . THE VEHICLE SHIFTS FINE AT HWY SPEEDS. I HAVE ALREADY BROUGHT IT TO THE DEALERSHIP TWICE AND PROBLEM IS STILL THERE. TALKING TO OTHER PEOPLE WITH GM 8 SPEED TRANSMISSION AND THEY ARE HAVING THE SAME ISSUE. 8 SPEED TRANSMISSION NEEDS RECALL. POSSIBLY TORQUE CONVERTER.

ENGINE HESITATION, OR MISFIRING. JERKING, OR TRANSMISSION SHUTTERING WHEN ENGINE IS AT LOW RPM AND ON INCLINE. (I.E. WHEN TRAVELING ABOUT 45MPH AND START UP A HILL, THE RPM'S ARE ABOUT 1300, AND THE TRANSMISSION DOESN'T GEAR DOWN, SO IT STARTS SHUTTERING UNTIL YOU GIVE IT MORE ACCELERATION THAN USUAL.) AFTER DEALING WITH THIS ISSUE FOR NEARLY 8 MONTHS AND 15K MILES, I BELIEVE THIS SAFETY ISSUE SHOULD BE RECALLED. DEALER ORIGINALLY ACKNOWLEDGE THE PROBLEM BUT WAS UNSURE OF THE CAUSE. AFTER 5 REPAIR ATTEMPTS THE DEALER SAY THEY CAN'T DUPLICATE AND THE VEHICLE PERFORMS AS DESIGNED.

IN JUNE OF 2017, I BOUGHT A NEW CHEVROLET SILVERADO. IT RUNS GREAT NO PROBLEMS. IN NOVEMBER 2017 I CALLED TO MAKE AN APPOINTMENT TO HAVE THE OIL CHANGED. THE SERVICE DEPARTMENT TOLD ME THAT THERE IS A RECALL ON THE CHUGGLE DRIVE QUALITY. THE SERVICE DID WHAT WAS NEEDED TO BE DONE. I HAD TO MAKE A 5-HOUR TRIP UP NORTH WHEN I NOTICED THAT MY TRUCK WASN'T RUNNING LIKE IT WAS BEFORE THE RECALL WAS DONE. I NOTICED THAT THE TRANSMISSION WAS SHIFTING HARD. WHEN THE CYLINDER DEACTIVATION WENT TO 4 CYLINDERS THE ENGINE LUGS. BEFORE THE RECALL WAS DONE I COULDN'T TELL WHEN THE CYLINDER ACTIVATION WAS SWITCHING TO 4 CYLINDERS BACK TO 8 CYLINDERS IT RAN VERY SMOOTHLY NO LUGGING OF THE ENGINE. WHAT CONCERNS ME NOW IS WHEN I WAS DRIVING AN WENT TO MAKE A LEFT TURN AT SLOW SPEED THE TRANSMISSION DOWNSHIFTED HARD WHERE THE BACK WHEELS LOCKED UP. WENT THROUGH A DRIVE THROUGH AFTER I PLACED THE ORDER PROCEEDED TO THE WINDOW MY TRUCK LUNGED FORWARD FROM FIRST GEAR TO SECOND GEAR. I AM GLAD THAT NO ONE WAS IN FRONT OF ME. I HAVE TAKEN IT TO THE SERVICE DEPARTMENT AT THE DEALERSHIP SEVERAL TIMES. WAS TOLD NOTHING WAS WRONG NO CODES CAME UP. EVEN CALLED GM GOT NOWHERE WITH THEM. THE CHUGGLE DRIVE IS A REPROGRAMMING OF THE TRANSMISSION CONTROL MODULE. GM TRYING TO FIX ONE PROBLEM CREATED ANOTHER PROBLEM. I PULL A 5000-POUND CAMPER WITH THIS TRUCK WITH THE ISSUES I AM HAVING NOW WITH THE TRANSMISSION SHIFTING HARD AND ENGINE LUGGING I AM AFRAID IT MIGHT CAUSE ME TO HAVE AN ACCIDENT. MY TRUCK RAN PERFECTLY BEFORE THE CHUGGLE DRIVE QUALITY RECALL WAS DONE. THE RECALL HAS TO BE THE PROBLEM. IT'S NOT A GOOD FIX.
