What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2003 Mercedes-Benz Sl, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

I WAS DRIVING HOME FROM WORK AND MY ABC LIGHT VISIT WORKSHOP LIGHT CAME ON. OK, THAT'S FINE I'LL TAKE IT TO THE SHOP TOMORROW. WHILE ON MY WAY HOME MY CAR SUDDENLY DROPS IN HEIGHT AND A WARNING SIGN CAME ON SAYING "STOP DRIVING, CAR TOO LOW." I PULLED TO THE SIDE OF THE ROAD AND NOTICED THAT MY CAR HAD MAYBE AN INCH OF CLEARANCE IN THE FRONT. THIS IS VERY DANGEROUS BECAUSE IF IT FEEL ANY LOWER I WOULD BE DEAD DURING RUSH HOUR TRAFFIC. I DROVE MY CAR TO THE SHOP AND LEFT IT THERE AND WAITED FOR A FRIEND TO PICK ME UP. I'VE READ MANY FORUMS ON THIS PROBLEM AND IT LOOKS LIKE IT HAPPENS VERY SUDDENLY AND CAN BE A DEADLY HAZARD. THERE SHOULD BE A RECALL FOR THIS PROBLEM. *TR
