2010 Mercedes-Benz CL65 AMG
Buttons on temperature control assemblies work erratically due to wear of parts in control head
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.
Spilling sticky liquids around cup holder may cause lid to stick/break
Cracked Driveshaft Flex Discs May Cause Driveshaft Movement/Vibration
A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.
Side Window Glass May Delaminate
The side window glass can delaminate. If this were to occur, replacement of the affected window would be necessary.
Center Console Armrest May Break
The center console armrest can break. Replacement is commonly the recommended repair.
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.
Poor AC performance Due to Evaporator Temperature Sensor Failure
The evaporator temperature sensor can fail, causing the AC compressor not to cycle. If the AC compressor does not turn on, the AC system will not blow cold air. If the compressor is stuck on, the air will be very cold at first, before warming up.
Vanity Mirror Door May Break
The door for the vanity mirror (or the frame for the door) can break; due to a redesign, the mirror "cassette" will need replacement.
Front Thrust Arm and Control Arm Bushing Can Crack or Tear
Front thrust arm and control arm bushings can crack and sometimes tear completely. If this is not repaired quickly, damage to the front subframe unit will occur, which is very expensive to repair. Updated control arms (that prevent damage to the subframe when the bushings wear out) are available.
Brake Light Switch Failure May Cause ESP/BAS Warning Lights
The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern.
The Differential May Develop Leaks From the Seals or Cover
High mileage or older vehicles commonly develop leaks from the differential seals and/or cover. Our technicians recommend a complete reseal of the differential unit whenever these leaks are repaired.
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).
Engine Misfire and/or Lack of Power
Engine misfires (rough running) and lack of power are commonly caused by ignition coil pack or ignition module faults. Proper diagnoses should isolate the cause and prevent unnecessary replacement of good parts.
Door Control Module May Fail
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.
Transmission May Leak Fluid and Damage Control Module
The electrical connector at the automatic transmission may leak fluid into the wiring harness. If not repaired, the oil will migrate through the wiring harness and damage the transmission control module. At that point, a new harness and control module may be necessary to correct this problem.
Command, Voice Control, PSE, & Tele Aid Modules and CD Chnagers Are All Prone to Failure
CD changers, command units, voice control units, PSE units, and Tele Aid units are prone to failure, especially in early models.
Analog Tele Aid Units Must be Upgraded to Digital
Analog Tele Aid units are no longer supported and must be updated to digital, preferably at a dealership or a well-equipped independent shop. The update and all related factors should be completed at the same time.
