Known issues on the 2015 GLK350. The federal record holds four recalls for the 2015 GLK350. On certain 4MATIC versions, the steering coupling connecting bolt may not have been tightened enough, which could lead to lost steering; dealers check the bolt and tighten it as needed. Certain vehicles could have the driver air bag go off unintentionally, and dealers added grounding to steering components. A software fault in certain vehicles could put the emergency call system's date and time out of step and pass along a wrong location, delaying responders; an over-the-air update or dealer software work corrects it. Complaints total 112, with air bags at 83, the electrical system at 7 and the fuel/propulsion system at 5; 3 complaints reported a crash, 3 an injury, 1 a fire and 1 a death. Steering, air bag and electrical procedures, wiring diagrams and diagnostics are covered.
