2007 Mercedes-Benz SL550 Problems

Suspension & Steering -- Verified

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.

Miscellaneous -- Verified

Leaks in the pneumatic system will cause problems with the dynamic seats and the trunk and/or door closing assist.

Engine -- Verified

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.

Brakes -- Verified

Due to the size and material used on the brakes of these vehicles, the brakes may start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain).

Electrical & Lights -- Verified

The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern.

2007 Mercedes-Benz SL550 Reviews

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 displaying an "Check Oil Level" message. Now the engine has a broken internal part requiring engine removal. This is a sweet ride but the cost of maintenance and numerous trips for repair are annoying and consume a lot of time.

Great driving car. Best convertable yet
