2003 Mercedes-Benz SL500 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.

Engine -- Verified

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

Drive Train -- Verified

Leaks may develop from the differential cover and/or seals on high mileage or older vehicles. Our technicians recommend a complete reseal of the differential unit if these leaks are addressed.

Suspension & Steering -- Verified

The lower control arm bushings can wear and crack, resulting excessive movement at the control arm pivot point, leading to irregular and premature tire wear. Worn Ball joints can also cause similar tire wear symptoms. I some cases it may be necessary to replace the lower control arm, including bushings & ball joint to correct this concern.

Brakes -- Verified

As brake fluid becomes dirty over time, it can cause a failure of the anti-lock brake system (ABS) modulator assembly. Our technicians recommend a complete brake system flush every two years to help prevent this issue.

2003 Mercedes-Benz SL500 Recalls (Recent)

Brakes, August 8, 2005

RepairPal Expert Overview:

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.

Brakes, October 21, 2004

RepairPal Expert Overview:

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.

2003 Mercedes-Benz SL500 Reviews

this car is a problem to the extent I would NEVER consider another Mercedes, at any price. they are junk. Batteries, top, Brake light, you name it. JUNK

JUST PURCHASED MY 2003 SL-500 W/49,000 MILES JULY 2012....SINCE HAVE REPLACED A ABS/SBC/AND NOW THE ABC NEEDS REPLACED ..THEY DIDN'T TELL ME THAT MY WALLET HAD A PUMP IN IT ..LOVE THE CAR BUT TOTALLY DISSAPOINTED IN THE CUSTOMER SATISFACTION....MERCEDES YOU HAVE LET ME DOWN ! IF YOU BUY A MERCEDES YOUR REPAIR BILLS IS MORE THAN YOUR PAYMENTS!

Bought this car one year old in 2004 with 7k miles on it. Has been a fairly good ride. Lots of fun when it isn't cost you at every turn. If you buy this car, set up a saving account to cover all the consistent costs. Good luck

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.

Well, I purchased my SL500 new in 2003 and it has not had any issues. I just have it periodically serviced with the A and B schedules. You guys must have purchased vehicles that had a hard life.
