Mercedes-Benz SL550 Problems

Active Body Control System Can Leak Hydraulic Fluid

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.

Evaporator Temperature Sensor Failure

The evaporator temperature sensor can fail, causing the AC compressor not to cycle. If the AC compressor does not turn on, the AC system will not blow cold air. If the compressor is stuck on, the air will be very cold at first, before warming up.

Wear causes noise at vario roof seals on high mileage vehicles
On higher mileage vehicles, wear causes noise at the vario roof seals. Lubricating the seals can usually cure the problem; in most cases, the seals do not need replacement.

Mercedes-Benz SL550 Recalls

Front Passenger Seat Air Bag May Not Deploy Properly

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.

Passenger Front Air Bag May Shut Off Unintentionally

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.

Potential Fire Due to A/C Refrigerant Leak

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.

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.
I love mine...It's the best car ever!!!
I purchased the SL in 2010, it had 10,400 miles on it. It now has just over 31,000 miles on the odometer. About 6 months ago a valve in the suspension malfunctioned. The extended warranty covered the valve replacement but I ended up paying $600 for fluid replacement. A month ago a hydraulic line in the suspension broke spraying fluid every where. A sensor periodically malfunctions displayi...
