About the Terrain

The Terrain crossover SUV first made its debut in 2009. Since its release, only two generations have hit the markets. The second was released in 2018 and received an update in both 2021 and 2022.

The model is currently the smallest offering in GMC’s SUV lineup. This puts it just below the GMC Acadia. It also shares the same platform as its Chevrolet counterpart, the Chevy Equinox.

Competition in the crossover class has been fierce for a while now due to increasing popularity. This means the Terrain has faced rivals like the Honda CR-V, Mazda CX-50, and Volkswagen Tiguan.

During its time on the market, owners have reported a number of shaft issues to plague the Terrain. P0011 is one of the most common of these. This code indicates that the intake camshaft is over-advanced.

Similarly, fault code P0014 is another common issue for the Terrain. This is the same code but for the exhaust camshaft.

These can typically be the result of failing VVT valves. Another common cause is a faulty camshaft position sensor for the respective shafts. Despite being a serious issue, its common fixes for it are relatively simple and affordable.

Adding to these issues, fault codes P0016 and P0017 have also been reported to be common issues.

These codes indicate that the signals from the intake and exhaust camshafts respectively are not correlating with the crankshaft signal.

All of these codes are very serious as they can lead to significant damage if left unchecked. Terrain owners should always tackle the first codes before attempting to solve the latter issues as resolving codes like P0011 can fix the other problems.
