Mercedes-Benz GL450 Suspension Problems

How to fix your Mercedes-Benz GL450 suspension problems the right way

by Troy Hammond on December 10, 2019 Categories: Maintenance & Repairs

Are you having trouble with your Mercedes-Benz GL450 air suspension? You are not alone. Unfortunately, air suspension issues are quite common with this full-size SUV. The air suspension in your GL450 gave the German luxury vehicle a smooth, cloud-like ride when it was new. However, after some years on the road, it has started to show signs of aging. Owners may notice these problems in different ways. Some might see evidence of suspension failure from the outside. One common example is the car sagging low in the rear. You might also find your GL450 leaning to one side. Sometimes owners can hear the evidence. If the compressor is running too loud or too long, it’s a sign that it’s working too hard. This would indicate a suspension fault somewhere in the system. You might also feel that difference.

A car driving on bad struts will take much longer to stop. When it does, it often dips forward with the back popping up, looking like it is crouching. This is referred to as a “nose dive.” Mercedes also included a suspension warning light that will illuminate when there is a problem. However, this might come later than some of the physical symptoms. If you are noticing any of these symptoms in your Mercedes-Benz GL450, it is time to have your suspension serviced. However, there is a lot to consider before making any big financial decisions about these repairs.

Repairing your Mercedes-Benz GL450 air suspension

If your suspension problems took you to the dealership, they likely recommended replacing the busted components with new air suspension components. A repair quote that made you do a double-take probably accompanied that recommendation. The reality is that air suspensions are highly complex and therefore expensive systems. They rely on a web of interconnected parts working together in order to function properly. Your Mercedes-Benz GL450 has ride height sensors at each wheel. These sensors send a signal to the control module, letting it know how much the air bags need to be inflated or deflated. Then, the control module sends this information to the compressor.

The compressor pushes air into the airbags. These rubber sacks are what suspend your car off of its wheels. Each one of these components is highly specialized. As you may have noticed, many of them are moving parts, electronic parts, or parts made with flexible materials. These are all prone to failure. As you can guess, these are all expensive parts to replace. Not only that, they are very labor-intensive and complicated to install.

Other options for your Mercedes-Benz GL450

This might sound pretty intimidating. However, you do have other choices for your Mercedes. This kit from Strutmasters allows you to do away with that troubled air suspension forever. You can ditch it and kiss all those recurring suspension problems goodbye.
