I leased one around Thanksgiving, the motor blew up before new year's, transmission overheated after having it for 3hrs. GM replaced the motor and now it has a missfires in cylinder 1&4 and classified it as a lemon! GM want to only give me 80% of money and will not give 1¢ to us for our troubles to buy a different vehicle. Basically said you get what you get and like it or to bad since we pay the BBB and we're a billion dollar company and could careless if you buy from us and been a loyal customer for 15yrs.

I am disappointed in my terrain. No wow factor, Seats are uncomfortable and material is terrible. Interiors is Ok. Shifters on Dashboard not needed, more of a hassle then anything Acceleration and Handling are great.

I have a 2018 GMC Terrain with only 6,000 miles on it. It's been in the shop so far 33 days. My infotainment screen freezes, sensors go off, doors lock and unlock by themselves, trunk opens randomly and it shifts clunky yet GMC still stands by their car with no respect to the consumer. They cant fix it and told me to stop bringing it in for service even though I have multiple videos showing the problems.

Got a lemon. It had rust within 1 year of driving it, which needed to be repaired over wheel wells (probably elsewhere too but I just can't see it). Has a serious electrical issue that power cuts to vehicle completely for a second or two when trying to come out of autostop and then several error messages regarding steering, brakes, traction - which tells me those components probably temporarily lost power as well. Tried to fix it no less than 5 times - replaced fuse block, replaced steering gear, fixed a bunch of plugs etc etc... problem still won't go away. Went for a drive on a typical winter day, a wheel well panel shifted back towards the front passenger door, which then buckled when the door opened (warranty won't fix that one). Been talking to GM head office for FIVE MONTHS. I call them constantly. They are doing absolutely nothing. Offered to trade in at GMC they are giving me rock bottom offer "because the vehicle has issues" - and yet its only halfway through warranty. Worst experience ever. Do NOT spend this kind of money on this piece of garbage and such awful customer service. Apparently this is built to their factory standard.

I purchased a 2018 GMC Terrain SLE-2 in February of 2018. Since the day I bought it pretty much @ 300 miles I started having issues with it. Right off the bat the AC was broke, the first time I tried to use it, it wouldn’t work. Then I started having problems with the transmission, but every time I took it to the dealership they told me they ran a diagnostic on it checked the fluids and there’s nothing wrong with it and would send me home. At times they would keep it up to a month while I was in a shitty Buick rental go kart. Finally I got fed up enough after taking it into the dealer over nine times and them telling me there was nothing wrong when it was very apparent there was something wrong when I would try to drive my car and it simply would not drive so I contacted the Better Business Bureau and they helped me file a lemon law claim. It was a long process, but I finally was able to get out of that vehicle not be under on my loan and have a new vehicle! I did have to go with another GM vehicle in order to not have to eat $4000 but at least I have a vehicle that runs like it should! So to anyone who is having issues with their vehicle and has taken it into the dealer three times or more for any issue I suggest contacting the Better Business Bureau to see what action you can take because GM will not help you at all if you’re in this position!
