I have a 2018 GMC Terrain that I have been paying for for almost two years. It has 63,064 miles on it. Five weeks ago, I was in a parking lot and the brake assist started acting up, then the vehicle wouldn't start. So, we had it towed to the nearest GM certified dealership. Here is a list of things that have been wrong with it in five, going on six weeks. First they discovered that the vacuum pump apparently blew apart and sent shrapnel through the motor, so they ordered a new one, which is when we discovered that we are 64 miles outside of the power terrain warranty….64 miles, and GM would not cover it. Ok, fine...thank God, I bought a bumper to bumper 100,000 mile warranty, so I'm covered. They replaced the vacuum pump, the car wouldn't start. So, soon there after they discovered there was sand in the vacuum line, then discovered that the timing was off by 13°, then I suppose fixed that, car still won't start. So, they replace the actuator, car still won't start, now they are trying to replace the cam. I won't know until next week if warranty has okayed the cam replacement. My husband and I believe that the engine needs to be replaced because of the shrapnel being shot through everything. I trust the guys at the dealership and believe they are trained properly, but let's face it things happen and stuff gets missed, and we are terrified that something is going to be left behind. Or, they could call it a loss and GAP can cover it, and we can get a different vehicle that hopefully we can trust. But GM isn't budging on anything, and are frankly very rude. I even had one woman tell me that she didn't even know what a cam was, laughed at me, and when I started to get a little frustrated, she hung up on me. Needless to say at this point, I am beyond frustrated, and will NEVER buy another vehicle that has ANY relations to GM, and I highly recommend that noone else does. When things go bad, they will do less than nothing to help you.
Will never purchase a GMC again

Car will lock me in or out of my car I have 7 videos. I have Shown to dealership and because it’s not happening when taken in. Nothing they can do. It’s a safety issue is what it is. I have a 9 month old. I’ve called on star and asked them to do a diagnostic. They see nothing on there end. My vehicle had 6200 miles and it’s been in the shop 4 times. I am so unhappy.

2018 Terrain transmission Problem at 8000 miles!

I am extremely disappointed with my purchase. I bought my car zero miles hoping I wouldn't have any issues for a while but boy was I wrong. I started noticing the car shifting hard. I called and made an appointment to take my car in to the dealership. I took the car in and of course the transmission tech didn't find anything other than a system update to the TCM. Two days later I called the dealership to bring back the car because issue was not resolved. On Friday as I was driving my car to the dealership, the car stopped shifting on the freeway and I barely made it to the dealership (I had my two small children in the car). I am so disappointed. I would of never expected this to happen to a brand new car. My car has 8000 miles. I wouldn't recommend this car. Look elsewhere.

2018 Terrain Changes

The lack of gear shift takes a lot of getting used to - the auto stop feature is annoying - the size of the overall vehicle change has reduced interior cargo space - can hardly fit our mother's transfer chair into the back on this model - noticed that the ride has become more bouncy with the change in the size of this model - the window views are smaller and more difficult - the overall changes in what was the best designed GMC Terrain up until the end of 2017, has ruined what was an outstanding vehicle not only in its appearance, but also in comfort and convenience. Don't like the changes made to this SUV at all, we are leasing, and unless major changes are made, we will not probably lease another one. We loved our 2015 Terrain.
