2003 Mercedes-Benz CLK430 Problems

Instrument Cluster Displays May Lose Pixels

The instrument cluster display may lose pixels and need replacement. However, if the back lighting bulbs for the odometer display in the center of the cluster burn out, they can be replaced.

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.

Cables in Convertible Top May Break

Cables in the convertible top tend to break. If the convertible top stops operating prior to reaching the desired open or closed position, the micro switches that sense the position of the top may have failed.

i just love this car.i bought in 2008 it has 25,000 miles on it.now it has 125,000 and it still drive the same.just change air filter that was it.
Purchased an 03 in 2009 with 23k on the odo, no problems of signifigance, and unlike newer "electronics filled" benzes there's not too much that can/does go wrong with these. Stock ride is a little "floaty" (for those who prefer a more performance oriented ride), and the car is a little under powered, as compared to 2010 V6's or turbo 6's.. but still a great car with a CLASSIC look!
I purchased this car for my wife in October 2006. She loves the car - I enjoy driving it too when I'm allowed to do so. My only complaint is the high cost of maintaining it. The cost may be a function of the high dealer cost here in Charlotte - I'm reluctant to take it to an independent - but perhaps I should change my reluctancy. I've been informed that I should change the spark plugs ever...
