Mercedes-Benz SL55 AMG 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 engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

There is a faulty software calibration that affects several areas including shutting off the fuel supply in a collision. This could cause a fire hazard during an accident. Dealers will reprogram this software. The Mercedes-Benz recall number is 2008 070001. This recall began during August, 2008.

Transistors used in the front signal acquisition and actuation module (SAM-F) may have been damaged during module assembly. As a result, the module could fail without warning, increasing the risk of a crash. Dealers will inspect and replace the affected modules as necessary. This recall is scheduled to begin on May 2, 2008. The Mercedes-Benz recall number is 2008 030005.

Due to deterioration of the wiring harness connection or failure of the hydraulic pump, the sensotronic brake control (SBC) system may default to the hydraulic back-up mode. In the back-up mode, the driver has braking power sufficient to stop the vehicle, but greater brake pedal pressure is required and brake pedal travel will be noticeably longer. Dealers will install a bracket and replacement ground wire to the SBC pump unit on all affected vehicles. Additionally, dealers will inspect and replace the SSC pump unit in certain SL models. The Mercedes-Benz recall numbers are 2005070007 AND 2005110001.

Mercedes-Benz SL55 AMG Reviews

I can't stop smiling. UNMATCHED beauty and performance. Several people have complimented me once, twice then a third time on how beautiful this car is. I agree. Undoubtedly destined to become a classic, this car is as docile as a kitten until called upon to perform. Then it becomes a well controlled beastly powerful driving machine! The transition is pure magic. Son - park your motorbike. Yo...

Great car. MB need to do more R@D on the suspention. Have had to replace the supention flud pump with 90,000 miles on car. 3800.00. And has a gear shift lock out problem that will not let you shift the car out of park, 1200.00. You wold expect a car that cost that much to live up to the MB reputation for relibinlty.

Very strong drivetrain. Issues are with electronics and accessories, particularly Active Body Control. Shame the rest of the car isn't a great as the engine and transmission, but it still is a wonderful beast! It's a completely different car from the standard SL with the non-supercharged engine.
