Mercedes-Benz S600 Active Body Control System Can Leak Hydraulic Fluid
Mercedes-Benz S600 Problem

ABC fluid leaked out while sitting in the garage called MBUSA. This company does not want to admit that there is a serious problem with these ABC systems. However they put the blame on the dealer. My dealer in SC has supported me fully with the repairs. Current owner of two Mercedes Benz MBUSA will never have to worry about me owning another one. My dealer is great, but the customer service of MBUSA backing their inferior product convinced me that MB has lost its edge on quality. PRODUCT AND CUSTOMER SERVICE!

Puddle of ABC fluid on garage floor after sitting 2 months until winter passes. Was in shop 5k miles ago for ABC damper replacement. Very poorly engineered car with multiple problems other than ABC. I can expect a major repair bill every 1000 miles. Average of $1000 to $2000 per repair. Garbage car. Garbage engineers. Garbage Dealerships.
This is the third time I had a problem with the ABC system. The first time I heard a pop sound and found that some oil was leaking, then six month later the problem happen again, with oil leaking again, and now again. Why can't the Mercedes Dealership fix the problem right the first time.

Having the same active body control, spent too much money already fixing it

Leaking fluid; ride height compromised. In for repair discussion tomorrow. Just flushed brakes 5k ago; not sure if there is any relationship, probably not.

At first the car just slumped on the driver's side, but then I started getting ABC warnings every time I hit a dip in the road followed by a complete failure of the ABC. The suspension stopped suspending the car
