2003 Mercedes-Benz CL500 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.
Cracked Driveshaft Flex Discs May Cause Driveshaft Movement/Vibration
A vibration felt through the center floor of the vehicle can be caused by cracked and/or shredded driveshaft flex discs, resulting in excessive driveshaft movement. If not repaired, damage to the driveshaft center support bearing, transmission, or differential can occur.
Stalling and/or "Crank no Start" Due to Failed Crankshaft Position Sensor
The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.
Squeaking/Worn Brake Pads May Require Rotor Replacement Also
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).
ABS Modulator Failure Due to Dirty Brake Fluid
The anti-lock brake system (ABS) modulator assembly may fail due to dirty brake fluid. Our technicians recommend a complete brake system flush every two years in order to help prevent this problem.
The Differential May Develop Leaks From the Seals or Cover
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.
Side Window Glass May Delaminate
The side window glass can delaminate. If this were to occur, replacement of the affected window would be necessary.
Transmission May Leak Fluid and Damage Control Module
The electrical connector at the automatic transmission may leak fluid. Over time leaking fluid could migrate through the wiring harness and damage the transmission control module. If that happens a new harness and control module may be necessary to correct the problem.
Buttons on temperature control assemblies work erratically due to wear of parts in control head
Engine Oil Leak From PCV Vent Housing and/or Engine Inspection Plate
An engine Oil leak may develop from the PCV vent housing on the valve cover and/or the inspection plate on the front of the engine.
Spilling sticky liquids around cup holder may cause lid to stick/break
Oil leak at oil sensor
Center Console Armrest May Break
The center console armrest can break. Replacement is commonly the recommended repair.
Harmonic Balancer May Fail and Damage Timing Cover
The rubber bond in the harmonic balancer can decay, which causes the balancer to move and work its way toward the timing cover. If the balancer comes into contact with the timing cover while the engine is running, it will fracture and damage the cover and potentially other surrounding parts. The harmonic balancer should be inspected at every service.
