2013 Mercedes-Benz GL450 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2013 Mercedes-Benz GL450

Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.

As a way to increase braking performance, the brake pads and rotors are make of a softer material and may be in need of replacement after approximately 20,000 miles; owners should be vigilant about getting their brakes checked.

A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.
