About this model
The Mercedes-Benz GLS, formerly Mercedes-Benz GL-Class, is a full-size luxury crossover SUV produced by Mercedes-Benz since 2006. In each of its generations it is a three-row, seven-passenger vehicle positioned above the GLE. The GLS is considered the flagship of the marque's SUV lineup, although the body-on-frame G-Class is more expensive and has been in production longer.

Regulator investigations
Opened by NHTSA's Office of Defects Investigation. An investigation is a question the regulator asked about a possible defect, not a fault it found — most end without a recall.

What the maker told its dealers
Service bulletins are the manufacturer's own repair guidance to dealers, filed with NHTSA. A bulletin is not a defect finding; the count rises with how many things a maker writes down, not only with how many go wrong.
