2011 GMC Terrain Owner Comments

problem #2

Terrain 4-cyl

  • 4,800 miles


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 issue is only happening on 2011 I-4 2.4L engines. Many people with this engine (Terrain and equinoxs for a couple) have the same issue. The vehicle makes a rattling noise when starting up..its intermittent. Also I have had (as others have) had the car stall and give an check engine light with code P0011. The car makes the rattling when car is cold or hot..I have it happen at least once a day. GM had a tech. Bulletin out on it in Feb.2011. The fix did not take care of it. In June 2011 GM put out another TB saying 'they are aware of the issue, have no fix yet'.. again this is happening on alot of these vehicles..as of right now, GM is not helping me with this..just that they are aware and will let me know..in the meantime, im driving a new car that makes a horrible noise, I don't know what internal damage its causing, and im afraid its going to stall again, in traffic and I will have an accident...
