I AM FILING A COMPLAINT BECAUSE RECALL ID# 08V303000-ELECTRICAL SYSTEM IS AFFECTING MY CAR AND MERCEDES REFUSES TO FIX IT. IT IS A SOFTWARE CALIBRATION THAT MADE MY CHECK ENGINE LIGHT COME ON. WHEN I TOOK IT TO MB THEY SAID THAT THE RECALL DID NOT EXIST. THEN THEY SAID THAT IT EXISTED AND APPLIED TO THE 2003 CLK (WHICH IS WHAT I HAVE) BUT NOT TO MY VIN. THEY ARE TRYING TO CHARGE ME TO GET THIS SOFTWARE CALIBRATED WHEN IT'S UNDER A RECALL FOR OTHER VEHICLES OF THE SAME YEAR AND CLASS. *TR

I HAVE A 203 MERCEDES-BENZ CLK320 WITH ONLY 32,300 MILES ON IT. THE SPEEDOMETER NEEDLE DOESN'T WORK ON MY INSTRUMENT CLUSTER. I GET A DIGITAL READOUT , BUT NOTHING FROM THE NEEDLE.

I HAVE BEEN QUOTED $1,000 TO REPLACE THE INSTRUMENT CLUSTER AND FEEL THAT I SHOULD NOT HAVE TO PAY FOR THIS SINCE IT IS A KNOWN AND SOMEWHAT WIDESPREAD ISSUE. *TR

I OWN A 2003 CLK320 COUPE. YESTERDAY, I TOOK MY CAR INTO FRESNO MERCEDES AND WAS VERY DISAPPOINTED WITH MY TREATMENT.
