let down terrain

2018 GMC Terrain SLE 4dr SUV (1.5L 4cyl Turbo 9A)

Very overpriced. Last year satellite radio standard on all SLE models and above, as were power up and down driver seat. Only back-up camera is standard all other safety equipment is optional, infotainment package (995.00), Driver convenience package (1375.00), Driver alert package-safety (980.00). Gm is also charging an extra 395.00 for any other color other than white. This makes this suv approximately $4000.00 more expensive than compared with the same relative equipment, i.e, Volkswagen Tiguan. Honda CRV. Very disappointing, especially since they moved production to Mexico that must have saved production costs. Gm considers GMC the premium brand, but may inspection and test drive disproved that, was ready to buy but too many let downs, very disappointed.

Really, an ideal SUV for anyone looking for compact fuel economy (40mpg) and high tech features.

Not very dependable

Numerous exhaust / DEF issues. Just put in the 3rd transmission. Turbo went out when shop test drove it after Trans was replaced. Parts are almost impossible to acquire. When it runs it is awesome. Currently at 42 days in the shop for this issue. It has left me stranded 3 times in 1 year. DEF sensors get replaced every 9 months. The last one GM warranted the part but no labor. Averages 36 mpg. It’s a great car when it runs. Still not very dependable. Current transmission has been in 1 year. It does slip sometimes but GM states nothing wrong. I’m pretty sure it will go out again before warranty is up. UPDATE: The diesel engine is the least reliable power plant offered. Transmission and turbo failures plague the diesel drivetrain. Lots of emissions issues as well. Buy the gasser and not the diesel.
