I OWN A GMC 2011 TERRAIN. IT HAS 3600 MILES ON IT. EVER SINCE I BOUGHT IT THERE IS A HESITATION AND IT DOESN'T SEEM TO KNOW WHEN TO SHIFT GEARS!.IT ALSO JERKS ALL OVER THE PLACE I BROUGHT IT TO THE DEALER BECAUSE ONE DAY IT ALMOST COMPLETELY STALLED ON ME. THE DEALER SAID THAT THERE WERE NO CODES THAT CAME UP ON IT AND EVERYTHING IS FINE. THE KICKER IS THAT THE SERVICEMAN WHO TOOK CARE OF ME TOOK IT HOME AND SAID THAT IT IS DOING WHAT I SAID AND THAT THEY CAN'T DO ANYTHING ABOUT IT UNTIL IT SHOWS A CODE ON THE COMPUTER. I CALLED GM AND THEY TOLD ME THE SAME THING. MEANWHILE I GET IN MY CAR TODAY,START IT UP AND IT MAKES THIS HORRIBLE LIKE GRINDING NOISE FOR LIKE 3 SECONDS AND THEN WENT AWAY. VERY IRRITATED WITH THE WHOLE SITUATION. IF I COULD RETURN THIS CAR I WOULD . I CANT STAND IT . I PAY GOOD MONEY ON A MONTHLY BASIS AND THIS IS WHAT I GET. SO UNTIL GGGGGGGMC GETS WITH THE PROGRAM AND ADMITS THAT THERE IS A MAJOR ISSUE WITH THIS VEHICLES ENGINE I THINK WERE ALL IN FOR ALOT OF HEADACHES. AND FROM WHAT I'VE READ THERE'S A FEW PEOPLE WHO ARE HAVING THE SAME PROBLEM.OH WAIT DON'T LET ME FORGET THE LOVELY VIBRATION MY CAR MAKES BETWEEN 2 AND 3000 RPMS! GOOD TIMES! *TR

FUEL/PROPULSION SYSTEM
I STARTED OUT DRIVING ON HIGHWAY ROAD AT APPROXIMATELY 5:45PM TRAFFIC WAS MODERATE, MY SPEED WAS ABOUT 30-35 MPH. ALL OF A SUDDEN I HEARD A CLUNK AND THEN ALARM DING FROM THE DASH AS WELL AS MESSAGE "SERVICE STABILTRAK" THEN "REDUCED ENGINE POWER". I WAS UNABLE TO GO ANY FASTER THAN 25MPH. I DROVE IN THIS MODE FOR ABOUT 2 MILES IN TRAFFIC, WHEN REACHING OPEN HIGHWAY (NO TRAFFIC) THE VEHICLE WOULD NOT SHIFT BY ITSELF. I HAD TO ACCELERATE THEN LET OFF THE GAS, TAP PEDAL THEN THE VEHICLE WOULD SHIFT. I WAS ABLE TO DO THIS MULTIPLE TIMES UNTIL REACHING ABOUT 45MPH. I PULLED OFF INTO A NEIGHBORHOOD, SHUT VEHICLE OFF TO SEE IF THIS WOULD RESET SOMETHING, IT DID NOT. THE VEHICLE WAS IN THIS STATE WHEN I ARRIVED AT THE DEALERSHIP SERVICE DEPARTMENT AT APPROXIMATELY 6:05PM. DEALERSHIP LOGGED FOLLOWING ON SERVICE REQUEST: 5043 FOUND CODE P228C RAN DIAG COULD NOT DUPLICATE PROBLEM FUEL PSI AT SPEC RAISES TO SPEC TEST DROVE ON HIGHWAY DID NOT DUPLICATE CONDITION FOUND NO BULL ON CONDITION TEST DRIVE NUMEROUS TIME, COULD NOT DUPLICATE CONCERN. MILES OUT 5067. *TR
