2011 GMC TERRAIN Complaints

THE TRANSMISSION SHIFTS HARD AND JERKS AT TIMES, DEALER STATES IT SHIFTED FINE WHEN THEY DROVE IT. IT HAPPENS MOSTLY IN SLOW RUSH HOUR TRAFFIC. I WILL SEE IF IT CONTIUUES AND DRIVE IT WITH THE DEALER ON THE NEXT VISIT. IS HAS ONLY 8000 MILES ON IT. *TT

VEHICLE IS NOT DELIVERING THE EPA FUEL ECONOMY PERFORMANCE RATED. THE GMC TERRIAN FWD 4CYL IS RATED 22 CITY, 32 HWY, AND 26 OVERALL. I DRIVE 30% OF MY MILES IN THE CITY AND 70% HWY. MY VEHICLE HAS 5000 MILES AND I AM EXPERIENCING 17 CITY, 22 HWY, AND 20 OVERALL. ALL WELL BELOW THE EXPECTED RANGE. I AM A VERY CONSERVATIVE DRIVER, NO JACK RABBITT STARTS AT STOP LIGHTS, USE CRUISE CONTROL. I HAVE COMPLAINED TWICE TO GMC AND WAS TOLD IT TAKES APX 5000 MILES TO "BREAK IN" THE VEHICLE. I NOW HAVE 5000 MILES AND AM NOW BEING TOLD TO USE HIGH OCTANE FUEL. FUEL PERFORMANCE IS SO POOR I SUSPECT A GAS LEAK OR SOME FAULTY COMPONENT THAT MAY BE POTENTIALLY DANGEROUS DUE TO THE EXCESS CONSUMPTION OF FUEL WELL BEYOND THE CONTROLLED EPA ESTIMATES. *TT

3 PROBLEMS WITH MY 2011 GMC TERRAIN AWD, 2.4 LITER 1. POOR GAS MILEAGE - AVERAGING 18.8 MILES FOR A VEHICLE RATED 20 CITY, 29 HWY. I DRIVE 42 MILES DAILY, 4 CITY, 38 HWY. DEALER CHECKED, NO CODES AND STATES "OPERATING AS PER DEIGNED INTENT" 2. JERKY TRANSMISSION SHIFTS AND SEVERE HESITATION ON STARTUP AND SLOW SPEEDS IN ECO MODE. DEALER CHECKED, NO CODES AND STATES "OPERATING AS PER DEIGNED INTENT" 3. ENGINE "KNOCK" ON STARTUP THAT LAST FROM 3 TO 10 SECONDS, NORMALLY ON "COLD" STARTUP. DEALER CHECKED AND COULD NOT DUPLICATE COMPLAINT, CHECKED CAM PHASER SCREENS PER SERVICE BULLETIN AND STATES NO DEBRIS IS PRESENT. DEALER STATES NO CODES ARE PRESENT AND NOTHING THEY CAN DO. OIL AND OIL FILTER WERE CHANGED AT MY REQUEST. ENGINE KNOCK AND POOR GAS MILEAGE STILL EXIST, TRANSMISSION ISSUE SEEMS TO HAVE CHANGED TO NORMAL AND SLIGHTLY HARD SHIFTING NOW AFTER DEALER VISIT. *TR

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

TRANSMISSION SLIPPING/JERKING ON MY GMC TERRAIN SUV-SLE MODEL. I HAVE TAKEN IT TO THE DEALER 2TIMES FOR THE SAME PROBLEM. THEY SAY THERE'S NOTHING WRONG, BUT IT'S STILL JERKING, IT'S HAPPEN WHEN THE GEAR SHIFTING (IT'S AN AUTOMATIC) THE CHANGE OVER IS NOT SMOOTH. THE MECHANIC SAYS IT'S DOESN'T HAPPEN WHEN THEY DRIVE IT OF COURSE, BUT THIS DOES NEGATE THE FACT THAT IT IS HAPPENING. PLEASE HAVE SOMEONE CHECK INTO THIS PROBLEM. BECAUSE I'M SURE IT'S HAPPENING TO OTHER TERRAIN OWNERS. *TR

MY 2011 GMC TERRAIN HAS A 2.4L 4 CYLINDER FRONT WHEEL DRIVE. IT IS RATED AT 32 MPG HIGHWAY. SINCE DAY 1 I HAVE NOT EVEN GOTTEN CLOSE TO THIS. I DRIVE 100 MILES A DAY AND MAYBE 5 MILES OF IT IS CONSIDERED CITY DRIVING. I AM GETTING 20 TO 22 MPG. I CONTACTED GMC AND THEY HAD ME TAKE IT IN TO BE CHECKED OUT. THE DEALERSHIP HOOKED IT UP TO THERE COMPUTER AND SAID THAT EVERYTHING IS THE WAY IT SHOULD BE. THEY THEN TOLD GMC THAT IT IS WINTER NOW AND FUEL MILEAGE WILL DROP DUE TO COLD WEATHER. I AGREE WITH THAT BUT NOT 10 MILES TO THE GALLON. MAYBE 2 OR 3 AT THE MOST. I CANT GET THEM TO DO ANYTHING ABOUT IT, I AM TIRED OF HAVING TO PAY OUT EXTRA MONEY FOR GAS WHEN THIS VEHICLE IS NOT PERFORMING TO ITS EXPECTATIONS. *TR

ON 11-21-10 MY FIVE YEAR OLD SON BUMPED HIS HEAD ON A HARD SURFACE THAT WAS NOT SAFELY DESIGNED OR PADDED PROPERLY. THIS HAPPENS WHEN THE BRAKES ARE APPLIED STRONGLY. NOTHING WAS DONE BY GM TO CORRECT THIS ISSUE. *TR
