2016 Chevrolet Colorado

WHEN DRIVING ABOUT 35 MPH, AND THEN PRESSING THE GAS PEDAL TO ACCELERATE / PASS ANOTHER VEHICLE, THE ENGINE REVS UP TO 4000 ' 5000 RPMS, BUT DOES NOT DOWNSHIFT. IT THEN TAKES A FEW SECONDS TO GO BACK TO 1200-1500 RPM RANGE. IT MAY DOWNSHIFT AT THAT POINT, AND THE TRUCK WILL JERK VIOLENTLY. I TOOK IT TO THE DEALER WHERE I BOUGHT IT NEW. THEY SAID GM IS AWARE OF THE PROBLEM AND REFERRED TO TSB PIP5547. I TOOK IT IN AGAIN IN DEC. 2019 BEFORE THE WARRANTY EXPIRED. THEY HAD THE VEHICLE FOR 18 DAYS. THEY AGREE THERE IS A PROBLEM, BUT GM HAS NO FIX FOR IT. THIS IS A REPEATABLE PROBLEM, HAPPEN CONSISTENTLY IN THE 30 TO 40 MPH RANGE. THE MANUAL STATES THAT WHEN TRYING TO PASS AT LESS THAN 35 MPH, PRESS THE ACCELERATOR HALFWAY DOWN, AS I HAVE DONE. THAT IS WHEN THE ENGINE REVS UP BUT DOES NOT DOWNSHIFT LIKE IT NORMALLY SHOULD. BUT THEN THE DOWNSHIFT DOES OCCUR WHILE THE RPMS ARE COMING BACK DOWN, AND THE TRUCK JERKS VIOLENTLY. THIS IS DANGEROUS BECAUSE I AM UNABLE TO RELIABLY PASS ANOTHER VEHICLE AT THIS SPEED. ALSO, THE SAME BEHAVIOR WILL OCCUR IN THE 50 TO 60 MPH RANGE. THIS IS VERY DANGEROUS WHEN USING AN ON RAMP TO GET ON AN EXPRESSWAY.

AFTER I PARKED THE TRUCK OUTSIDE IN ABOUT -15 FOR ABOUT 4 HOURS, I STARTED THE TRUCK AND TRIED TO PULL OUT THE DRIVEWAY BUT EXPERIENCED A LOST OF POWER STEERING. I COULD BARELY TURN. FORTUNATELY, MY FRIEND LET ME USE THEIR HEATED GARAGE. I LET IT SAT FOR ABOUT 15 MINUTES, STARTED IT, AND STILL NO POWER STEERING AND THE "SERVICE POWER STEERING" MESSAGE WAS SHOWN. LET IT SAT FOR ANOTHER 15 MINUTES, INITIALLY NO POWER STEERING AND SAME DIC MESSAGE, THEN ALL OF A SUDDEN IT STARTED WORKING. DROVE 20 MINUTES HOME WITHOUT FURTHER PROBLEMS. BUT THAT MADE ME WORRY THAT IF IT HAPPENS AT SPEED, THE OUTCOME WOULD BE VERY DIFFERENT!

THIS IS THE 2ND TIME THIS HAS HAPPENED. ONCE IN 2018 APPROX FEB. THE STEERING LOST ALL ELECTRIC ASSIST. THIS ALWAYS APPEARED AFTER IT WAS DRIVEN AND HAD BEEN PARKED. IT DID THIS ABOUT 4 TIMES BEFORE THE DEALER WOULD REPAIR IT. AT THAT TIME EVERYTHING WAS COVERED BY WARRANTY. THIS TIME, THE SAME PROBLEM, LOSS OF ALL STEERING ASSIST AFTER DRIVING AND IT WAS PARKED. SAME ISSUE, THIS TIME THEY TELL ME THE STEERING GEAR BOX NEEDS TO BE REPLACED AT A COST OF OVER $2000.00. EXACTLY THE SAME ISSUE THE 2015 WAS HAVING. I HAVE READ THE COMPLAINTS AND I FEAR THIS WILL HAPPEN AT HIGHWAY SPEED. WE LIVE IN AN EXTREME COLD CLIMATE AT TIMES AND BOTH INSTANCES MY VEHICLE WAS PARKED AFTER DRIVING IN -20F WEATHER.

I KEEP GETTING INFO MESSAGES WHILE DRIVING TO SERVICE STABILALINK AND POWER STEERING AND DRIVE WITH CAR AND I LOSE ALL POWER STEERING. IT HAPPENS MULTIPLE TIMES A DAY AND DEALER SAYS THEY CAN'T GET IT TO DO IT WHEN THEY DRIVE IT. AT HIGHWAY SPEEDS IT GOES OUT AND I HAVE ALMOST CRASHED SEVERAL TIMES DUE TO NOT BEING ABLE TO CONTROL MY STEERING. IT HAPPENS OFTEN AND 8 TIMES TODAY.

SERVICE STABLELINK COMES ON AND WITHIN SECONDS THE POWER STEERING TURNS OFF. I HAVE TO PULL OVER TURN OFF THE TRUCK FOR 15 SECONDS TO RESET THE COMPUTER AND MOST OF THE TIME IT STOPS. HOWEVER THERE HAVE BEEN TIMES WHEN IT DOES NOT RESET AND I HAVE TO DRIVE WITHOUT POWER STEERING. THIS HAPPENS RANDOMLY. I CAN BE STOPED ON THE HIGHWAY OR AROUND TOWN.

WHILE DRIVING FROM THE GROCERY STORE TO OUR HOUSE, THE STEERING WHEEL BECAME INCREDIBLY STIFF AND A MESSAGE APPEARED ON THE DASHBOARD WARNING ME TO SERVICE POWER STEERING AND DRIVE WITH CARE. I WAS MAKING A RIGHT TURN OUT OF THE PARKING LOT ONTO THE CITY STREET AND THE STEERING WHEEL WENT STIFF AND THE MESSAGE APPEARED. I HAD TO MOVE THE STEERING WHEEL WITH A LOT OF FORCE TO AVOID CROSSING OVER THE CORRECT LANE AND GO ONTO HEAD ON TRAFFIC. LUCKILY THE GROCERY STORE ISN'T FAR FROM MY HOUSE. IF MY WIFE OR SONS HAD BEEN DRIVING THEN THIS COULD HAVE ENDED BADLY. THIS ISN'T THE FIRST TIME I'VE LOST POWER STEERING. THIS HAS HAPPENED WHILE ON THE HIGHWAY. WHEN ON THE HIGHWAY I TURNED TO THE OFF RAMP AND AGAIN THE STEERING WHEEL WENT STIFF WITH THE POWER STEERING LOSS MESSAGE. SINCE THEN THE TRUCK DOESN'T SEE MUCH USE. LATELY, IT HAS BEEN GETTING SO BAD THAT THE POWER STEERING DOESN'T EVEN WORK AND STARTS STIFF WHEN FIRST TURNING ON THE TRUCK. SOMETIMES THE POWER STEERING ISN'T STIFF WHEN FIRST TURNED ON BUT THE LOSS OF POWER STEERING MESSAGE STILL OCCURS. THE TRUCK JUST SITS UNUSED BECAUSE IT IS FLAT OUT DANGEROUS TO DRIVE. I'VE CHECKED ALL OF THE FUSES AND THEY WERE ALL FINE. I'VE DISCONNECTED THE BATTERY FOR 20 MINUTES AND RECONNECTED IT AND THE STEERING WHEEL IS STILL STIFF AND THE SAME POWERING STEERING LOSS MESSAGE.

THE TRUCK WILL RANDOMLY SHUT OFF WHILE DRIVING, SITTING STILL, AND THEN START BACK UP WITH NO PROBLEM. THE TRUCK ISN'T REPORTING ANY CODES BUT THE ENGINE HAS RANDOMLY CUT OFF DURING OPERATION ON SEVERAL OCCASIONS. I HAVE READ MANY FORUMS OF OTHERS HAVING THIS ISSUE. THIS HAS HAPPENED TO ME WHILE PULLING OUT INTO TRAFFIC ON A CITY STREET AND ALMOST CAUSING A MAJOR ACCIDENT. IT OCCURRED AT SEVERAL TRAFFIC LIGHTS AND ALSO MERGING ONTO A HIGHWAY EXIT. THIS IS A MAJOR PROBLEM WITH SERIOUS RISKS INVOLVED!

THE DRIVERS WINDOW, WHEN I PRESS THE DOWN BUTTON ON THE CONTROL THE WINDOW WILL START TO GO DOWN THEN CLOSE BY ITSELF, ALSO I HAD AN ISSUE TODAY 11/13/19, I WAS ABLE TO GET THE WINDOW TO ROLL DOWN, BUT THEN NO MATTER HOW MUCH I TRIED THE WINDOW WOULDN'T ROLL UP..THE VEHICLE IS USUALLY IN MOTION WHEN I HAVE HAD THE ISSUE OF THE WINDOW ROLLING UP ON ITS OWN,
