The transmission shifting is erratic and creates a problem when in heavy down town traffic where there is stop and go traffic. Car will hesitate before it goes into proper gear.this is the 4 cylinder model I am driving.very had shift from 1st to 2nd gear at all times.I do not allow any of my family to drive this car because it has become a safety issue in my opinion.

I have a 2.5 month old 2011 GMC Terrain. At 4984 miles it is in the shop for stalling, for a horrible rattle upon start up, and for it jerking between first and second gear. When I took it in this morning it had stalled six times within the past 2 days. It stalls after start-up in forward and reverse and it stalled three times while in idle in a fast food drive-thru. There is also the rattling which happens on cold and warm starts, whether the A/C or eco mode are on. It sounds like metal rattling and like it is harming the engine. The least of my worries, is the fact that between 25-35 miles an hour the transmission shifts very hard and kicks myself and passengers forward. Apparently there is a tech bulletin that has been out for the rattle for several months. Why not fix them before they sell them? also, there is a recall #11195 for "rough idle, poor driveability" that doesn't show up on the NHTSA site or anywhere else but the GMC dealer's computer. Additionally, despite the claims, I have never gotten better than 21 mpg while driving this car including an all highway trip from Michigan to Indiana. I think it is false advertising and the fuel economy in eco or not is not what they claim when the Y sold the vehicle to me.

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.

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.

The contact owns a 2011 GMC Terrain. While driving approximately 15 mph and shifting from first to second gear the vehicle jerked. The vehicle was taken to the dealer twice and the technician performed updates to the electrical system. The vehicle continued to lunge after the updates. The approximate failure mileage was 800.
