2011 GMC ACADIA Engine And Engine Cooling Problems

AIR CONDITION NOT WORKING, LIGHT ON CONTROL BLINKS 3 TIMES AND GOES OUT. COULD BE EVAPORATER COOR. KNOWN PROBLEM WITH THIS MODEL. WHY IS THIS NOT COVERED UNDER WARRANTY. *TR

OVER THE PAST MONTH AND A HALF I HAVE BEEN NOTICING THAT WHEN I ATTEMPT TO PUSH THE GAS TO MAKE MY CAR GO FASTER THAT IT DOESN'T ACCELERATE. IT IS USUALLY WHEN MY VEHICLE IS ALREADY IN MOTION AND I ATTEMPT TO GO FASTER. I CAN HEAR IT MAKING A NOISE LIKE IT'S TRYING TO GO FASTER BUT THERE IS DEFINITELY A DELAY BEFORE THE VEHICLE ACTUALLY STARTS TO GO FASTER. USUALLY I AM ON A NORMAL STREETS GOING ANYWHERE FROM 35-55 MPH (DEPENDING ON THE STREET AND POST SPEED LIMIT), SO IT'S NOT ALWAYS A HUGE DEAL WHEN IT HAPPENS. I DO A LOT OF HIGHWAY DRIVING AND THIS IS WHERE MY CONCERN COMES INTO PLAY. A FEW WEEKS AGO I WAS MERGING ONTO 696. THERE WAS MORE THEN ENOUGH ROOM IN THE FIRST LANE FOR ME TO SAFELY MERGE INTO TRAFFIC, HOWEVER, WHEN ATTEMPTING TO ACCELERATE MY...

MY CAR SKIPS AS IF THE ENGINE IS NOT GETTING ENOUGH GAS. I WILL BE DRIVING ALONG AND THE ACADIA WILL SHAKE AND DO A LITTLE SKIP JUMP. IT DOES THIS AT LEAST A COUPLE OF TIMES A WEEK. I ALSO HAVE TO CONSTANTLY ADD OIL TO THE TRUCK EVEN WHEN I AM 1000 MILES OUT FROM MY NEXT OIL CHANGE. *TR

THAT'S WHEN MY CAR DROPPED FROM GOING 60 MPH ON CRUISE CONTROL TO 20 MPH AND I COULD NOT ACCELERATE. THANKFULLY, I WAS ALREADY IN THE RIGHT LANE AND WAS ABLE TO PULL ONTO THE SHOULDER. AT THAT POINT, I TURNED OFF THE VEHICLE AND WAITED, THINKING THAT THE ERROR MESSAGE WOULD GO AWAY AND IT'S JUST A COMPUTER GLITCH, AS THIS IS COMMON WITH THIS MODEL VEHICLE. I STARTED THE VEHICLE AGAIN AND IT HAD FULL POWER BUT THE ERROR MESSAGE TO "SERVICE TRACTION CONTROL" WAS STILL ON AND ALTERNATING BETWEEN THAT MESSAGE AND "TRACTION CONTROL OFF". THIS INCIDENT OCCURRED THREE SEPARATE TIMES ON THE SAME DAY ALONG...
