general problems of the 2015 GMC Terrain

The automatic emergency braking system just goes off without any reason, causing the vehicle to considerably slow down if not stop. This happens several times a week if not multiple times a day again for no reason. There is no advance warning , it just happens.

The front brakes and rotors have been changed twice in 2 months time, over $400. Something is causing the rotors to warp. The heat went out in the middle of winter because the blend door broke, $800. Also, about 6 months ago I had to have the timing chain and a gasket replaced because of the ongoing oil consumption issue, $1300. It's an expensive problem for the owners of these vehicles and no reasonable solution.

I have been having problems with my car sense I have owned it . From day one it started with my wheels rubbing and scrubbing when in motion . I called dealership had repairs done on it for the first 7 months . I reported the problem back then to you all. Then after 3 yrs I started to feel some hesitation when sitting or taking off . Then the forth year my power steering light comes on had that fixed now my engine light keeps coming on car still having some hesitation on and off . I paid to have a diagnostic test done on it by the place that does my oil change and was told that my codes where off and they were reset but 5 days later my engine light is back on ,ironically right after my five years limited warranty is over and my car only have 38,490 miles to this day and it is not yet paid for. This is ridiculous ,I have spent the last 5 plus years of dealing with this new lemon and all I get is another bill add to the 528. 02 a month I have to pay already. This car came highly recommended by the sales person and dealership and all I can see is that these cars are being push on hard working people that just want something reliable and its wrong. This car is frustrating and stressing me out ,I cant rely on it to get me through 5 more years I thought more of the GMC product and I cant take anymore of this trying to make this bad situation better on my own. GMC needs to do something about these defective cars please.

Steering to the left, but not always, there is a squealing noise. Continues to squeal driving straight and then stops. It is intermittent so when brought to my mechanic, he couldn't resolve. Charged me nothing. Didn't do it for a day and then I received a notification from onstar that there was an issue with my abs system and a second notification that stabilitrak system had an issue. It is very loud at times. I also have a squealing noise coming from the steering wheel and that is intermittent also.

Squealing sound, mostly after taking a left turn, as if it were coming from left rear tire and also a sound coming from steering wheel. Notified by onstar I may have an issue with both abs system or stabilitrak system. Sound is intermittent so when I brought to my mechanic it did not make the sound so he could not diagnose where it was coming from- no charge. One day later it started again. It sounds scary and I hope nothing happens if it is the brake system. This is why I sent this complaint in. This is second of two complaints because in the first, I forgot to mention where the noise sounded like it was coming from.

I've attached my final repair notice to gm and it has all of the details. I have since taken my car back to the dealership to have the final repair done. They still say nothing is wrong with it. I am terrified to drive my car. I asked gm to take the car back and they say they are not willing to do anything at all to help me. The transmission is jerky and the brakes barely work. Please investigate. Its like gm would like to wait until there is a huge accident and loss of life before doing anything.

While making a right turn at the bottom of a freeway offramp the keys on the keyring attached to the key in the ignition got stuck in the steering wheel. This briefly prevented me from exiting the turn, and then when the keys broke free the car had turned itself off!! I had no power steering, no power breaks and no headlights. I was on a slight downgrade and was able to coast to the next block where I turned right out of traffic before coming to a full stop. I was then able to restart the car after putting into neutral (or park, don't remember). The keychain that got stuck was from enterprise rental and had 2 key-fobs on it plus a plastic id tag on a small wire ring. This, combined with the poor placement of the ignition switch, has resulted in my hitting the keys with my hands while steering several times since renting the car 5 days ago. The ignition switch is located very close to the wheel and the ignition key which sticks out of the large key-fob is very close to the steering wheel even without other keys on the ring. Testing this in my driveway it is very easy to turn the car off while in drive. Very scary!.
