About This 2018 GMC Terrain SLE

This particular Terrain comes in at 118,383 miles — a mileage range that reflects real-world use but is well within what this platform is known to handle when properly maintained. The second-generation Terrain, which debuted for the 2018 model year, was a significant redesign over its predecessor — sharper styling, a more refined interior, and a more modern powertrain lineup. If you've been searching for a used GMC Terrain in Detroit or the greater Wayne County area, this Satin Steel Metallic example offers the kind of daily-driver dependability that fits Detroit's mix of highway commutes, city streets, and suburban runs alike.

Stock number 1482 is ready for a test drive, and the VIN (3GKALMEV9JL300393) is available for a full vehicle history report so you can buy with confidence.

2018 GMC Terrain Performance and Engine

Under the hood, this Terrain SLE is powered by a 1.5-liter turbocharged four-cylinder engine producing 170 horsepower and 203 lb-ft of torque. That torque figure is the real story here — it arrives low in the rev range, which means confident acceleration from stoplights, smooth merging onto Michigan freeways like I-75 or I-96, and a composed feel at highway speeds.

Paired with a 9-speed automatic transmission, the Terrain finds the right gear quickly and keeps the engine in its efficient power band whether you're crawling through downtown Detroit traffic or cruising on a longer weekend drive. The extra ratios in a 9-speed setup translate to smoother shifts and better fuel economy compared to older 5- or 6-speed units — a meaningful advantage over time at the pump.

GMC Terrain Features and Interior

The SLE trim positions this Terrain solidly in the middle of the lineup, delivering a strong collection of comfort and technology features without climbing into luxury pricing territory. GMC equipped the 2018 Terrain SLE with an infotainment system featuring Apple CarPlay and Android Auto compatibility, a rearview camera, OnStar connectivity, and a suite of driver convenience features that make daily driving noticeably more pleasant.

Interior Comfort and Everyday Usability

Inside, the second-gen Terrain felt like a step-change improvement from its predecessor. The cabin materials are well-fitted, the seating position is commanding without feeling truck-like, and rear passenger space is genuinely usable for adults. Cargo volume behind the rear seats is competitive for the class — practical for Costco runs, weekend trips, or hauling gear around Wayne County.

GMC Terrain Reliability and Ownership

The 2018 Terrain was an all-new design, and GMC invested heavily in making the second generation more competitive against the Honda CR-V and Toyota RAV4. The 1.5-liter turbocharged engine has proven to be a durable unit when owners stay current on oil changes — this is a turbocharged motor, so clean oil matters more than it does on a naturally aspirated engine.

What Owners Typically Report

Owners of the 2018 Terrain SLE consistently highlight the smooth transmission, comfortable ride quality, and intuitive infotainment system as standout positives. The 9-speed automatic occasionally drew early criticism for slight hesitation in some units, but software updates from GMC addressed this. At over 100,000 miles, it's reasonable to budget for maintenance items like spark plugs, brake components, and a serpentine belt inspection — standard wear items that keep any vehicle running strong well past this mileage mark.
