NHTSA 5-Star Safety Rating
The 2013 GMC Terrain draws complaints heavily centered on the engine, which accounts by far for the largest share of reports. Owners frequently describe sudden power loss, stalling at low speeds or when coming to a stop, and rough running accompanied by the check engine light. A recurring and more serious pattern involves engine failure, owners report discovering catastrophic internal damage, sometimes after noticing shuddering or misfires, with several describing metal debris in the oil pan and complete loss of oil pressure without prior warning. Exhaust-related issues, including catalytic converter and upstream exhaust component failures paired with sputtering and drivability problems, also appear across multiple reports. Visibility and wiper complaints make up the second-largest named category, though engine concerns clearly dominate the complaint picture for this model year.

By System
The 2013 GMC Terrain has 3 recalls, the most serious being a faulty park lock mechanism that may allow the ignition key to be removed while the transmission is still in gear, leaving the vehicle free to roll away as occupants exit.
On the visibility side, the windshield wiper module's ball joints can corrode over time, causing one or both wipers to stop working and leaving the driver with a rain-obscured windshield. The headlights on certain trims also produce an unintended reflection that throws excessively bright light above the vehicle and into the path of oncoming drivers, reducing their visibility.
At a glance
What can fail
The headlight housings reflect light upward and outward, creating excessively bright illumination above the vehicle and outside the driver's view, violating federal lamp safety standards.
What the fix does
Dealers will install headlamp appliques at no charge to correct the light reflection and comply with safety standards.
