ON 9/2019 THEY SUPPOSEDLY DID THE REPROGRAM TO FIX THE HYDRAULIC BRAKING ISSUE ON MY TRUCK. IT IS NOW DOING THE VERY SAME ISSUE AGAIN. I GO TO SLOW DOWN OR STOP AND FEEL LIKE ITS NOT SLOWING DOWN AND I PUMP THE PEDAL TO GET A GOOD PEDAL TO STOP. IT DOES THIS QUITE FREQUENT NOW. IS THERE ANYONE WHO CAN HELP ME SEE IF THIS CAN BE DONE AGAIN UNDER RECALL?

PINHOLE LEAK IN A/C CONDENSER APPEARS TO BE A SYSTEMIC PROBLEM IN NUMEROUS GM VEHICLES UTILIZING THE SAME PARTS.

THE PASSENGER SIDE REAR TURN SIGNAL QUIT OPERATING - THE COST FOR A NEW ONE IS MORE THAN $700

AFTER COMING TO A COMPLETE STOP AT TRAFFIC STOP LIGHT TRUCK'S TRANSMISSION MADE A LOUD "CLUNK" SOUND. WHEN ATTEMPTING TO ACCELERATE ON THE GREEN LIGHT TRUCK, INITIALLY WOULD NOT MOVE THEN IT LERCHED FORWARD BUT WOULD NOT SHIFT OUT OF FIRST GEAR. PULLED OFF MAIN ROAD AND INTO A PARKING LOT WHERE I SHIFTED TRUCK INTO PARK AND TURNED OFF THE ENGINE. AFTER WAITING A COUPLE OF MINUTES I RESTARTED THE TRUCK, SHIFTED INTO DRIVE AND PULLED BACK ONTO THE STREET, BUT THE TRUCK STILL WOULD NOT SHIFT OUT OF FIRST GEAR.

BACK WINDOW STARTED SMOKING NEXT TO HANDLE TO OPEN SLIDING WINDOW THEN SHATTERED THEN STARTED FALLING OUT. I WAS MOVING AND IN IN REVERSE BACKING UP WHEN THIS HAPPENED. (LEFT SECTION OF BACK WINDOW)

THIS HAPPENED MULTIPLE TIMES. THE BRAKE PEDAL IS HARD AT LOW IDLE, AND YOU HAVE TO STAND ON BRAKE PEDAL TO STOP THE VEHICLE. TYPICALLY HAPPENS WHEN TRYING TO BACK IN A PARKING SPOT OR IN STOP & GO TRAFFIC THE BRAKE PEDAL BECOMES HARD TO PUSH AND TRUCK DOESN'T STOP AS QUICKLY

MY TRANSMISSION SHIFTS VERY HARD FROM 1ST GEAR TO 2AND AND THEN FROM 2AND GEAR TO 1ST GEAR AT WHICH TIME I'M USUALLY STOPPING AND IT SEEMS TO PUSH THE TRUCK FORWARD A BIT. I'VE TAKEN IT TO PEKIN IL DEALERSHIP AND GREEN CHEVROLET IN PEORIA IL AND NEITHER ONE SAYS THERE IS ANYTHING WRONG
