Mercedes-Benz CL600 Problems
RepairPal has identified the most common problems with the Mercedes-Benz CL600 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
A door control module/actuator may fail. Our technicians recommend finding an expert to repair them. Taking the door trim panels off requires expert knowledge because they can break and the pieces are very expensive.
Other than a defective motor, a bad switch or blower motor resistor assembly can cause an inoperative heater blower motor.
A refrigerant leak may develop from one or more of the following AC components: AC compressor, hose manifold for the compressor, or the evaporator core. The loss of refrigerant can cause poor AC performance. Our technicians tell us that proper leak diagnoses should be performed in order to determine the cause of any refrigerant loss.
The engine oil coolers may leak; Our technicians tell us removal of the cylinder heads is required to correct this leak.
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.
A cracked or broken heater core outlet housing can cause a coolant leak near the bulkhead (firewall). Our technicians remind us that coolant leaks should be repaired in order to avoid overheating the engine due to coolant loss.
One or more door windows may stop working due to a failed window regulator. Replacement of the failed regulator will be necessary to correct this concern.
Irregular and premature tire wear can be caused by the lower control arm bushings cracking, resulting excessive movement at the control arm pivot point. Ball joints can also wear out prematurely, causing 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.
Due to wear, high usage vehicles can experience ignition lock and tumbler failures. The ignition lock cylinder will generally require replacement to correct this concern.
The electronic throttle assembly may suffer an electrical failure. It is often cheaper to send the valve to a service center for repair that to purchase a new part.
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.
