“Started car and got message: abc malfunction, car too low . In actuality, car elevated. The ride of the car has changed. It has a soft and floaty feeling compared to its normal stiffer ride. I have seen the above complaint on the internet multiple times. It seems this is a wide problem. I haven't heard any recalls from mercedes.”
NHTSA complaint #10660341, filed 2014-11, 45,000 miles“I was driving an 03 SL500 and from the start the battery light (white stayed on) replaced both front and back battery and voltage regulator, now the red battery light is on and stays on. On last night, while driving down the highway, I heard a pop, car dropped and warning came on saying car was too low and fluid is leaking from the front driver side look like by the front wheel. Mechanic did a lot of guessing and still not fixed.”

The car would drop low (on one side if parked for a few hours). Today, january 5, 2017 - the identical problem happened again. While driving, I heard a loud bursting sound and then hydraulic fluid began seeping out also, the abc red dash light illuminated stating that the car is too low to drive . I managed to slowly drive home (without power steering). This is a huge defect in mercedes benz technology and manufacturing - a class action lawsuit is absolutely necessary. …”
