ACTIVE CURVE SYSTEM MALFUNCTION on 2013 GL450 4Matic
X166 GL / GLS-Class
We have a beautiful 2013 GL450 4Matic with OffRoad Package and Sports Mode. The Active Curve System has not worked properly since we took ownership of the truck. I need assistance from anyone who has had similar issues with a X166 GL. I believe that the issue could lie in the stabilizer bar...

Did you raise the car up to take these pics or is it stuck in the lifted position too?

I’m also just surprised to see a 450 with those options, esp the active curve. I love active curve and was the must have feature when looking for our 550. Blew my mind to see so many 550s with options galore and no active curve. Active curve is just amazing and the new e-active is more responsive since it’s elec vs hydrolic.
