Mercedes-Benz SL500 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.

The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

As vehicles age, various problems may develop with the hard and soft tops. If problems are encountered, it would be recommended to have a technician familiar with these tops perform the diagnoses.

Mercedes-Benz SL500 Recalls

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.

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.

 

High mileage combined with a high number of brake actuations, or a high brake actuation frequency, can cause the pump motor of the SBC to run out of permissible tolerances. As a result, excessively high pressure may build the high pressure line of the brake system. If this occurs, the system will switch into the hydraulic function mode as designed. Sensotronic brake control is disabled when the brake system is functioning in the hydraulic mode. Dealers will inspect the SBC hydraulic unit and replace it if necessary to correct this concern. The Mercedes-Benz recall number is 2004 050014.

Worse car I have ever owned. Something on it breaks at least once a month sometimes more. I've owned it almost a year and have put maybe 6k miles on it and have spent about 12k on maintenance. She's like a hot super model, beautiful to look at, fun to ride but every time I get in her she cost me money.

I have 55K miles on the car and am the original owner. I get an average of 24 MPG in the city and 30 MPG on the highway. The car is wonderful and fun to drive. I have every bell and whistle you can imagine, including the laser cruise control (which I use all the time). Less than two weeks ago I was taking a short road trip and the transmission went out on the car – we’ll see if the car stil...
