2003 Mercedes-Benz CLK320 Problems
RepairPal has identified the most common problems with the 2003 Mercedes-Benz CLK320 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
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.
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.
Computer control modules for the seats and doors, the CD changer, and the brake lamp switch tend to fail.
Going over large bumps in convertible models may cause the roll bar to deploy, rendering the roof inoperative. Special tools are generally required to return the roll bar to its stowed position.
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.
Torque thrust bushings in the front suspension may crack and leak oil, this causes steering alignment problems and excessive tire wear. Another symptom of a worn bushing is a clunk or thud noted when turning, on hard acceleration, or hard braking.
An engine oil leak may develop from the oil level sensor. Replacement of the leaking sensor will commonly correct this concern.
The CD changer may suffer from an internal mechanical problem. Replacement of the faulty unit is generally required to correct this issue.
