Specs and fitment
Known issues for this generation
NHTSA complaints on 2013 and 2015 GLK filings are dominated by air bags. Recall 19V-010 covers certain GLK250 and GLK350 vehicles (among other Mercedes models) in humidity-based registration zones for passenger frontal Takata inflators that may explode from propellant degradation; the campaign lists about 288,779 vehicles across the covered population. Dealers replace the passenger frontal air bag module. Recall 17V-252 covers a small set of 2013-2015 GLK and 2013-2014 C-Class vehicles (168 units total across those nameplates) where the steering coupling bolt may have been incorrectly torqued; if the nut loosens, steering can be lost. Dealers inspect and re-torque the coupling as needed. Recall 16V-081 earlier covered certain 2010-2012 GLK models for driver-side Takata PSDI-5 inflators among a larger multi-model population of about 711,159 vehicles.
