Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted.
Airbag complaints dominate the 2010 GLK350's complaint picture by a wide margin, with owners frequently reporting the airbag warning light illuminating and staying on while driving. Many of these owners describe being told their VIN fell outside the coverage of an existing airbag service campaign, leaving them without a repair path. Fuel system complaints are the second most-reported area, where owners describe fuel pump components cracking and leaking gasoline, in some cases into the vehicle's interior. A smaller cluster of suspension complaints describes the rear subframe developing corrosion significant enough to cause instability during braking, with some owners noting the ABS and stability control systems also disabling as a result of the structural deterioration.

With Injuries
By System
The 2010 Mercedes-Benz GLK350 has 5 recalls, all involving the airbag system, with the most serious risk being frontal airbag inflators that can rupture and send metal fragments into the cabin, potentially causing serious injury or death.
Three of the recalls cover the front airbag inflators on both the driver and passenger sides. These inflators can explode rather than deploy normally, scattering sharp metal fragments toward the driver, passenger, or other occupants. A separate recall covers the airbag control unit, which can corrode and malfunction, causing the airbags to deploy without warning and raising the risk of a crash or injury. The inflator recalls are geographically scoped and primarily affect vehicles sold or registered in high-humidity states, while the control unit recall applies more broadly.
