Mercedes-Benz SL550 Problems
The active body control system can leak fluid from numerous areas, including the tandem pump, hydraulic lines, struts, and/or seals. If it is not repaired, the vehicle ride height could drop too low and cause damage to the undercarriage.
Leaks in the pneumatic system will cause problems with the dynamic seats and the trunk and/or door closing assist.
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.

Mercedes-Benz SL550 Recalls
In a crash that deploys vehicle air bags to protect occupants, the passenger seat air bag may not deploy, increasing risk of injury. Dealers will replace the passenger seat air bag free of charge to resolve the problem.
The occupant detection system may unintentionally shut off the passenger front air bag due to a sensitivity issue in the sensor mounted within the passenger seat cushion. Dealers will replace the passenger side seat cushion which includes the sensor free of charge to resolve the concern.
These vehicles are equipped with a new type of A/C refrigerant - R1234yf. Testing has determined that escaping R1234yf refrigerant may ignite under specific conditions. A severe frontal crash may rupture one of the air conditioner refrigerant lines, which can result in a gaseous mixture of refrigerant being released into the engine compartment. The resulting fire could spread to additional combustible materials. Dealers will replace the R1234yf refrigerant with R134a (which is the type that had been used previously) along with new refrigerant lines (hoses) designed specifically for R134a.
Mercedes-Benz SL550 Reviews
I love mine...It's the best car ever!!!
Great driving car. Best convertable yet
My car has 27,000 miles and starts shaking and making a funny noise. I have a 2009 GL 350, the display panel is not working. I really feel that Mercedes is no longer selling top quality cars that they use too.
