As i went to drive my terrain we bought back in June or July. But for the absolute first time we needed to use the defrost/defogger button last week on OCTOBER 20, 2022 and it wouldn't work. No lights came on to say it was defaulty. It also started to make our radio screen flicker when i tried to turn defrost on and it's continuously flickering and defrost doesn't engage on front windshield at all won't even melt snow or help defog when it's been raining or it's cold out. I almost wrecked my terrain due to this problem. Now on my instrument panel says camshaft/crankshaft sensor says service stabilitrack and something about my AWD System. All these happened within a week from trying to use my defrost. Also my instrument panel where it shows how fast i go flickers and it flickers on the RPM side as well. Noone has touched or looked it over since i have owned my 2010 terrain. Everything was just fine up till i pushed my defrost button and then all the other stuff happened

The oil consumption issue could cause vehicle to break down and GMC wants people to pay for test if used. Thats not right.

Cracked catalytic converter at 78,000 miles

8/26/13 we took our Terrain into a GMC dealer due to check engine lite coming on, was informed that the manifold was cracked. Paid dealership to replace the manifold and all gaskets. Almost 4 years to the date the same repairs are needing to again replace the manifold. This vehicle is only 8 year old and is used for highway driving. We have been advised that this is a possible design flaw or there is a weaken motor mount.

"takata recall" so far at 140,000 miles on my 2010 Terrain I have had to put a new engine in, all 3 catalytic converters and now a power steering pump and rack. I could have bought a brand new car by now. No recalls on any of these"?" there should be. The engine just stopped on the highway and once replaced then the steering became tight and barely made it to the shop

The defroster and heating stopped working. It blows out air but its cold air. I have always had to play with the control to get it to work but its never stopped working altogether until Friday, 11/25/2016. I live in the snow belt and I cannot defrost my windows to even see out of them. I see there was a recall in 2009 for my type of vehicle for the same type of issue. The controls for the door lock on the same panel also stopped working.

Uses way to much oil. We have to keep adding oil between oil changes. There is no leaks on the ground from leaking oil, it just burns oil fast. We have to check the oil at every fill up and most of the time we are adding about 2 qt. Or more.

I purchase my truck certified used and I already have to drop $1400 because the O2 sensor went out, the exhaust manifold is cracked and the hose that recycles the gas (I'm guessing the intake valve) is leaking! I still have to make car payments and insurance payments which total up to about $700 per month!!!! I am really dissatisfied as much as I love my truck.

The rear door air lift will not stay open when you press the button. On 2 occasions I hit my head because I did not know it had dropped down when I was loading and unloading groceries. The vehicle was parked in a parking lot and in my garage. It was not running. I found an entire page on the internet of many people having the same issues. It is called the Terrain forum.net. This is very dangerous because some people have said they have had them dead fall. People could be injured or killed by the force of this door coming down on their heads. GMC has recalls on this problem with some of their other calls but not the GMC Terrain. I talked with them today and they said they have not had enough complaints to have a recall! here is the link to the Terrain forum https://www.google.com/search?sourceid=navclient&aq=&oq=Terrain+forum&ie=utf-8&rlz=1T4adfa_en___us607&Q=GMC+Terrain+forums+discussions+&gs_L=hp..3.0J0I22I30L4.0.0.0.18414...........0.zc-sm_ruims#Q=lift+gate+will+not+stay+open+on+my+2010+GMC+Terrain

I have had my vehicle checked twice this year regarding the loud exhaust noise and the strong fuel smell coming from my vehicle. They said that it is not a concern and I get migraines from the smell as well. I take my little sister to school everyday and the the fumes are overwhelming.

Dashboard lighting fading on and off at radio portion, including time, temp, and station. At same time, noise coming from right front side of vehicle.

- Martinez, GA, USA

Dash shade too short. The sun shines straight down over the driver and reflects on the instrument panel and causes a severe glare. This could be corrected with a 3 inch longer hood over the driver instrument panel or 6-9 tinted strip in the upper windshield. I cannot read the instrument panel which I think is a safety issue.

Multiple problems: 1) front right tire well hole/leak found while investigating a complaint of mold odor inside car. 2) initially, the usb and A/C were malfunctioning. Then the car radio stopped working; and now the car will not start (possible electrical shortage related to the above leak?) I tried to charge the battery; however, I believe something may be draining the battery as it keeps dying.
