Mercedes-Benz S550 Problems
Check Engine Light Due to Faulty Camshaft Adjuster Solenoid
The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.
Cracked Driveshaft Flex Discs May Cause Driveshaft Movement/Vibration
A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.
Brake Pads & Rotors May Wear After 20,000 Miles
As a way to increase braking performance, the brake pads and rotors are make of a softer material and may be in need of replacement after approximately 20,000 miles; owners should be vigilant about getting their brakes checked.
HVAC Blower Motor May Fail
The HVAC blower motor may fail. This is commonly caused by water entry through the cabin air filter areas during heavy rain or snow. Failed blower motors should be replaced. Our technicians tell us there is no special fix for this issue at this time.
Stalling and/or "Crank no Start" Due to Failed Crankshaft Position Sensor
The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

Door Locks May Not Operate As Expected
RepairPal Expert Overview:
During production, on fifty-four Mercedes S-Class models, the front and rear door locks may have been mistakenly interchanged. This means that a rear passenger could open the rear door with a simple pull of the interior door handle, and the front passenger could not open by pulling on the interior handle. This situation could affect the safe exiting of the vehicle in a crash or protection against the accidental opening of the rear door by a child. Dealers will inspect the part numbers on all door locks and replace any that are incorrect. The recall began on March 27, 2009. The Mercedes-Benz recall number is 2009030001.

Mercedes-Benz S550 Stories
I love this car and am very happy I bought it BUT I am concerned. 1 - The clutch pads may have a problem (transmission "kicks" in low gear up a hill) and 2 - the exhaust seems loud. I have less that 1,000 miles on the car so I'll take some responsibility for learning how to drive this car but I am concerned. This is the most comfortable car I have ever owned and I love the creature features. Coming from a Lexus history (I hate the LS 460 so I changed to MB), that is hard to admit. I heard a lot of people complain about MBrace but it has been working like a dream for me (email my car directions from Google maps is so cool!).
2010 Mercedes-Benz S-550 with less than 3000 mi the solid torque strut brushings had to be replaced with hydraulic ones. My car has been in the shop 3 times with less than 5000 miles and the vibration still exist. Mercedes knew the problem existed with no solution yet have not disclosed the problem the public or some of their employees. My car is not worth $100,000 with the existing problem and no resolution. I fear for my safety and everyone in and around my 2010 Mercedes S-550.
I found the information RepairPal provided in the common problems section to be helpful and very timely. The common problems around the drivetrain is what I was experiencing and I've been given an estimate of approximately 9k to replace transmission and many other items. Please know an independent certified MB technician found this problem NOT the MB dealership!!! I ask how can a transmission have to be replaced in 2008 for a 2007 100k+ car? Let's see if MB will own up to this being a faulty transmission!
