Active body control (ABC) = expensive.
Coil packs (misfire) = expensive.

Tire pressure sensors.
Pneumatic door closing mechanism.
This car has been essentially a bad marriage for me. It's like I married a rich girl who wants you to maintain her wealthy lifestyle, and your job pays well but you're certainly not rich. Gimme, gimme, gimme is all hear! I just can't keep up. Seems like it's never enough. The owner before me did not do any of the maintenance, so it all fell on me ... one system after another ... and I'm ready to be DONE! He pretty much bamboozled me. I'd like to slap him to be frank.
The issues started with a leaking ABC up front. Once I repaired that the tire pressure sensors went. And then the ABC in back needed fixing, and that was followed by a loss of the pneumatic door closing system. SRS light for passenger seat comes on intermittently. It needed new tires too, which is to be expected. And most recently I fired it up and felt an instant vibration and the check engine light came on. F***!!!
Based on my research, this generation of S Class has a ton of sensors, and their failures give owners headaches. I feel like this is by design so you have to roll into the stealership so they can tell you what's wrong with your car. Lo and behold it's a sensor ... easy fix ... that'll be a $1000.
So I did some homework and this car has two major failures that occur on a consistent basis. The ABC goes out like clockwork due to the MBz using cheap O-rings. However, if you have an indie mechanic it can be done fairly cheap as the parts cost $70 (online); it's the labor that can be spendy. Some people recommend doing a flush every 40,000 miles, but you really just need to change out the old O-rings for new better quality material O-rings.
After the ABC the coil packs go out like every 30,000 miles. Each coil pack costs a little over $1000. At the stealership it's $1095. So before they even pop the hood you are looking at shelling out 2-4K, and then you'll need 24 spark plugs. OMG.
On the flip side this is an awesome automobile. It is fast, comfortable and stylish. When it starts up it rumbles on. And it eats up miles. You'll get there faster and more comfortable than any other car. Absolutely no one will beat you on the road. This car is fast and pulls very smoothly! Feels like it can pull forever and never get tired.
Would you buy another car from this manufacturer? Don't Know
