2020 Chevrolet Colorado

MY NEW CHEVY COLORADO TRUCK (10000 MILES) HAS EXPERIENCED VIBRATION ISSUED BETWEEN 30-60 MPH. TYPICALLY IT HAPPENS WHEN IN CRUISE CONTROL BETWEEN 50-60 MPH AND I TRANSITION FROM GOING DOWNHILL TO UPHILL AND THE ENGINE IS STARTING TO RE-ENGAGE AND ACCELERATE TO MAINTAIN SPEED. IT FEELS LIKE I AM GOING OVER RUMBLE STRIPS AND ITEMS IN MY GLOVE BOX CAN BE HEARD VIBRATING AROUND. APPARENTLY IT IS COMMON ENOUGH THAT ON THE INTERNET IT IS KNOWN AS THE "CHEVY SHAKE". I AM WORRIED ABOUT PREMATURE TRANSMISSION FAILURE. ALSO, IF THE INTERNET IS CORRECT, CHEVY HAS KNOWN ABOUT THE PROBLEM SINCE AT LEAST 2018. ALSO, IF THE INTERNET IS CORRECT, CHEVY HAS KNOWN ABOUT THE PROBLEM SINCE AT LEAST 2018. I HAVE ALWAYS IT WAS THE PAVEMENT CONDITIONS UNTIL I DID SOME RESEARCH ONLINE. I THINK I HAVE REALLY NOTICES IT WITHIN 3 MONTHS OF PURCHASE IN MAY 2020.

THE VEHICLE IS EXPERIENCING A SHAKE AND/OR SHUDDER DURING LIGHT THROTTLE ACCELERATION BETWEEN 25 AND 80 MPH STEADY STATE DRIVING WHEN TRANSMISSION IS NOT ACTIVELY SHIFTING GEARS. THE CONDITION IS AS IF I WERE DRIVING OVER RUMBLE STRIPS. TSB 18-NA-355 ADDRESSES THIS ISSUE IN 2017 - 2019 CHEVY COLORADO PICKUP TRUCKS WITH THE 8 SPEED TRANSMISSION. THE 2020 MODEL SHOULD BE ADDED AS IT DOES NOT APPEARED TO BE FIXED AT THIS TIME. I PURCHASED THIS VEHICLE BRAND NEW FROM THE FACTORY WITH ONLY 5 MILES ON IT. THE SHUDDER ISSUE HAS BEEN PERSISTENT FROM THE VERY FIRST DAY I DROVE IT.
