The 2010 GMC Terrain SLT is difficult to maintain. You will need to use a tool that you may not have readily available to remove a cover in the wheel well lining for access to many of the headlights. The tail lights won’t allow for reliable access, either, as you’ll need to remove the main rear bulb housing in order to reach them. Monitoring the power steering reservoir may be a problem as you’ll need to remove the engine cover first.
However, the 2010 GMC Terrain SLT does have its upsides. The fog light has reliable access as you only need to reach behind the front bumper to change it. Checking the fuses won’t be a problem on account of the unobstructed access to both of the fuse boxes. The spare tire and jack kit will both be easy to remove in the event you need to service a flat.
