I had my 2020 Terrain for 5 years before I had any major issues out of it. My brake booster needed replaced. After about a month of it being out the shop someone hit and totaled it. Very sad day. I love my Terrain

Great Reliability
Great vehicle, 65,000 miles and not a single issue, hoping to get atleast another 100k miles out of it. Extremely reliable. A family member of mine bought a Honda that broke down at 16,000 miles and got stranded. Would absolutely recommend a 2018+ terrain

I give 5+ stars to this dealership.
I give 5+ stars to this dealership. We accompanied our granddaughter to purchase her first car. Kim was the sales associate. She was awesome…no pressure, answered her questions, and helped her to get payments that were affordable. She found just the car that was best for her, with the help of Kim, at a competitive price. Everyone was so helpful and the finance department explained the paperwork in a way a first-time car buyer could understand. I definitely recommend Autos of Forney!
I LOVE the power
I really enjoy the Terrain. Traded in our beloved Mercedes R350. It was dream to driving on the highway. Our list for new vehicle was easy to get in and out without climbing up or down. No leather seats, hate leather seats, panoramic roof, engine power, get up and go, some luxurious in the vehicle, an easy info console. Before we took a test drive, we did our following tests. How easy to get in and out of the vehicles, leg space (our son is 6'4"). Only wanted two row seating, comfort seating. We checked all other makes. Spend awhile day going from different Dealerships of different makes and models. Didn't want to speak to car salesman, just let us do our preliminary test, on different makes and models. Then we look at the warranties. Finally took take a test drive. Was blown away at the get up and go of the Terrain, pleasantly surprised at the safety features and options it comes with. After almost a month, trips outside the city to the mountains and back. We are really happy with the purchase of the Terrain. Seven years warranty bumper to bumper, ten years on the powertrain. The true fuel economy really surprised me, it doesn't bother me that I have use 91 fuel because of the 2 liter engine. Had to use it on the Mercedes so no change there.
