What 2001 Mercedes-Benz CLK Class owners say

Electrical system

The instrument cluster in my 2001 Mercedes-Benz clk430 does not function properly. The pixels in the gear selector, temperature and clock section do not light up. This makes it impossible to tell what gear the car is in, and poses a safety hazard. The "p" and "r" are difficult to distinguish. This car has transmission problems, and the necessity to identify which gear the car is in by "feel" is dangerous.

Dash LED's are failing causing the drive indicator to not register correctly. When I place it in gear because the lights go on and off as a bad connection I cannot tell what gear I am in. Also the same LED's for the clock and temp are failing in the same unit.

Transmission & drivetrain

The automatic transmission in my 2001 Mercedes-Benz clk430 will frequently become stuck in only one gear. Most often 3rd gear, but sometimes 2nd. This is a terrifying situation for me, especially in traffic, as the automobile does not accelerate from a stop in 3rd gear and abruptly slows when letting off the accelerator in 2nd. 2nd gear also limits the speed of the car significantly and has caused me to be the traffic slowdown at rush hour on many occasions. I have had several close calls, as I cannot get the car out of a busy intersection quickly or change lanes to make a turn when this is happening. I drive my children in this car and am afraid that a 3rd gear start or a 2nd gear abrupt slowdown or its severely limited velocity will cause an accident and they May get hurt. The only way to remedy this situation is to pull over, shut off the car and restart it. …
