Alberto was my service tech. He did a great job explaining everything to me that needed to be done for my vehicle. He even suggested waiting to do some services later.

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

Amazing Service Department
Joe Mayer Ford is the best dealership I have ever been to in Houston, TX. After calling the Tomball Ford I purchased my car at, about a window that would not roll up I tried Joe Myers. They looked at my vehicle with hours of my car being dropped off, compared to many other places telling me they would not be able to do the same for about 4 days. Jordan in the service department expedited the part and I had car ready a full day early! Simply amazing and the most helpful service time I have ever dealt with.
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.
