Known issues on the 2014 GL450. For the 2014 GL450, the federal record lists three recalls. The smallest, affecting 69 certain vehicles built between November 4 and November 15, 2013, involves a folding second-row seat bottom that might not drop far enough to expose the child seat lower anchors, so a child restraint could be poorly secured; dealers replace the seat pan if necessary. Certain vehicles equipped with the Active Curve System could vent foaming oil from an underfilled reservoir, a fire hazard near an ignition source. Emergency call software on certain vehicles could report a wrong position. Owners have filed 21 complaints, seven about the engine and three apiece about visibility and electrical. Seat, suspension and engine procedures, wiring diagrams and diagnostics are provided.
