2007 Mercedes-Benz GL450 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2007 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.

An engine Oil leak may develop from the PCV vent housing on the valve cover and/or the inspection plate on the front of the engine.

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.

I have power stern fluid in it so is it the pump, the belks, or is it two power sterling pumps?

When I first get in and start my car, the rear is low and rough pulling out of garage. I wait and it builds up pressure like on a bus and is better. I've had this problem before a long time ago.
If the car sits for any time, I see it is low again.
Is it a value or strut or airbag? I do no...
