For the 2013 Mercedes-Benz GLK350, the complaint picture is dominated by airbag and restraint system issues, which account for the large majority of reports filed. Owners most commonly describe passenger-side airbag components behaving unexpectedly, including head restraints deploying or activating without any collision or impact. Steering complaints appear in a smaller cluster, with owners reporting noise and handling symptoms that sometimes surface after shop visits. A handful of reports involve the fuel system, where owners describe a strong odor during or after refueling, concentrated near the rear passenger area. A single report mentions brake lines rusting through prematurely, causing brake failure, but that appears in isolation rather than as a repeated pattern. The airbag and restraint category is clearly where complaint volume concentrates on this model year.

By System
The 2013 Mercedes-Benz GLK350 has 6 recalls, the most serious involving a steering coupling bolt that may not be properly tightened, which can cause a complete loss of steering control.
Two airbag recalls cover the Takata inflator issue: the passenger-side airbag inflator can rupture and send metal fragments into the cabin, posing a risk of serious injury or death. A separate recall addresses the driver airbag, which can deploy without warning and raise the risk of a crash. On the exterior lighting side, vehicles built during a narrow window in mid-2012 have headlights that project more light than allowed, creating glare for oncoming drivers. There is also a software fault in the emergency call system where the date and time may be incorrect, causing the system to relay an inaccurate vehicle location to emergency responders if activated.
