To who may this concerned, I have a 2003 Mercedes SL500 and recently found my battery control module caught on fire and burnt a section of my car. I have tried reaching out to Mercedes directly first and they said the car is 20 years ago and it could have not be a manufactured defect. Please I need help this problem could’ve burn down my house or while I was driving. Mercedes requested I send them a letter in writing if I have to get the car inspected. Please setup and date so I can write them this is 100% liability on their brand as there is no schedule maintenance for a battery control module.

ABC (Active Body Control) light keeps coming on and body goes up and down when I drove car. Light says do not drive. Mercedes would not take responsibility for this in spite there are so many complaints about this. Really irresponsible by Mercedes.

I was driving my car at 45 mph and suddenly, unexpectedly a red light flashed ABC do not drive. Smoke was coming from under the car and the front end of the vehicle collapsed downwardly. I had to call for a tow truck to take my vehicle to the MB dealership. I'm I am waiting for the prognosis. I've had numerous issues with the All Body Control system. Expensive repairs in the $3000-$8000 range. This is a safety issue the breakdown happens abruptly and I was fortunate other cars weren't on the parkway with me. Otherwise a crash could gave occurred.

The 2003 SL500 with seemingly no instigating incident or event had the gas tank baffle come apart due to the poor and faulty design of this component. This baffle now is loose and floats on the gas in the gas tank, banging around when there is acceleration or deceleration, even turning sometimes causes it to bang around. Speed bumps are another source of loud banging from the baffle bumping into the sides of the tank. The issue with 2003 SL500's is ubiquitous, it is not a question of what percentage of them will experience as it appears it will happen to this vehicle at some point due to the poor design and implementation of the baffle. This wouldn't be such a big problem if this was a minor repair and was a reasonable price to have a shop perform or for the more mechanically inclined owner to perform themselves, but it is a ridiculously complex and time-consuming job just to get to the gas tank and take it off. My mechanic told me it is akin to taking the transmission or engine out and as such labor is outstandingly and outrageously expensive with this job requiring approximately $2000-$2500 to perform according to my mechanic and other SL500 owners who have also had to deal with this issue. This is an issue that you may not experience if you don't own one of these vehicles for long enough, but the vehicle will have this problem during it's lifetime and Mercedes should be responsible for allowing such a design to make it into production.

It has been nearly two years I have stopped driving my 2003 Mercedes SL500, although I only have about 80,000 miles on the car. This is due to ABC warning light(red display: please drive carefully)comes on intermittently and the car drives very bouncy and it feels the car has no shocks, definitely feeling it would be unsafe to drive. The diagnostic message comes up saying "visit workshop". This is the third time this ABC pump issue is stopping me from driving the car, since it first appeared when I had 29,000 miles on the car which was under manufacturer warranty (50,000 miles or four years) and the dealership replaced the ABC pump and also replaced the engine mounts. The ABC red light appeared again when I had about 51,000 miles on the car. It happened also the engine mounts were in need of replacement again. As the Warranty was only for 50,000 miles, Mercedes refused to repair the ABC pump and the engine mounts under warranty and finally I agreed to a 50% cost to me to have repairs done. I expressed my opinion that the ABC pump and the engine mounts had engineering and manufacturing defect and they should have 50,000 miles warranty as the original warranty, from the time of replacement. Regrettably, same ABC malfunction and engine mounts became an issue at 78,000 miles and now the dealer and Mercedes refuse to replace the ABC pump and engine mounts under warranty and have given an estimate of $7336.36 for the necessary replacement of parts, including labor, but excluding ta

MY CAR IS A 2003 MERCEDES BENZ SL500. THE ABC LIGHT KEEPS COMING ON AND THE CARS SUSPENSION CONTINUES TO RAISE AND FALL. MANY TIMES ONE SIDE HIGHER THAN THE OTHER AND NOT EVENLY. IN 2013 I HAD A SIMILAR PROBLEM AND ENDED UP COSTING ROUGHLY $3200. OBVIOUSLY, THIS IS AN UNSAFE MECHANICAL ISSUE. AFTER REVIEWING YOU SITE FOR RECALLS ON MB 2003 SL500, IT APPEARS THERE WAS A RECALL FOR THIS PROBLEM ON MY MODEL YEAR AND CAR. AFTER SPEAKING TO MB OF SARASOTA AND MBUSA IT WAS VIN# SPECIFIC AND MY VIN WASNT INCLUDED. I AM VERY CONFUSED HOW THIS DOESNT COVER MY VEHICLE. NHTSA CAAMPAIGN NUMBER : 08V405000. OBVIOUSLY, THIS SHOULD NOT BE VIN SPECIFIC AS MY CAR HAS THIS PROBLEM FOR THE SECOND TIME AND VERY EXPENSIVE TO CORRECT. IT IS A DANGEROUS MECHANICAL DEFECT THAT MB SHOULD TAKE CARE OF. ANY HELP WOULD BE APPRECIATED.

WHILE DRIVING MY MERCEDES BENZ 2003 SL500 THE BRAKES BECAME DISABLED WITHOUT WARNING. IT WAS A TERRIFYING EXPERIENCE. THE FIRST MERCEDES DEALER I PHONED TOLD ME THAT THERE WAS NO KNOWN SAFETY RECALLS FOR THE BRAKES. THE SECOND MERCEDES DEALER THAT I CONTACTED INFORMED ME ABOUT 2 RECALLS IN 2004 AND 2005. I PHONED THE MERCEDES BENZ USA HEADQUARTERS AND SPOKE TO A CASE MANAGER WHO TOLD ME THAT MERCEDES' RESPONSIBILITY WITH THIS SAFETY ISSUE EXPIRED IN 2012. HOW CAN A SAFETY ISSUE SUCH AS HAVING NO BRAKES WHILE DRIVING EXPIRE? HOW CAN A CORPORATION BE ALLOWED TO WALK AWAY FROM THIS TYPE OF POTENTIALLY DEADLY SAFETY ISSUE? THIS IS A WELL DOCUMENTED SAFETY ISSUE WITH THIS CAR.

WHILE DRIVING THE CAR IN TOWN ON CITY STREETS THE SBS BRAKE SYSTEM FAILED AS I CAME TO A TURN LEAVING ME WITH NO BRAKE RESPONSE EVEN THOUGH THE DEALER SAYS IT WAS SUPPOSED TO HAVE HYDRAULIC BACK-UP TO STOP THE CAR. I WAS ABLE TO COAST AND STOP THE CAR ONLY WITH THE EMERGENCY HAND BRAKE. THE SBS SYSTEM HAS BEEN RECALLED TWICE BY THE FACTORY BUT THERE IS STILL SOMETHING VERY WRONG WHEN A MODERN CAR HAD NO BACK-UP SYSTEM. THESE CARS ARE DANGEROUS! LUCKILY FOR ME THERE WAS NO ACCIDENT AND I HAD THE CAR TOWED TO THE DEALER AND IT IS BEING REPAIRED.

I OWN A 2003 MERCEDES BENZ SL 500 AND REPLACED THE HYDRAULIC PUMP IN 2014 FOR $6400.00. THE CAR WOULD DROP LOW (ON ONE SIDE IF PARKED FOR A FEW HOURS). TODAY, JANUARY 5, 2017 - THE IDENTICAL PROBLEM HAPPENED AGAIN. WHILE DRIVING, I HEARD A LOUD BURSTING SOUND AND THEN HYDRAULIC FLUID BEGAN SEEPING OUT ALSO, THE ABC RED DASH LIGHT ILLUMINATED STATING THAT THE CAR IS "TOO LOW TO DRIVE". I MANAGED TO SLOWLY DRIVE HOME (WITHOUT POWER STEERING). THIS IS A HUGE DEFECT IN MERCEDES BENZ TECHNOLOGY AND MANUFACTURING - A CLASS ACTION LAWSUIT IS ABSOLUTELY NECESSARY. THIS VEHICLE IS DEFECTIVE AND DANGEROUS TO OPERATE. ALSO, CONSUMERS SHOULD NOT SPEND THOUSANDS UPON THOUSANDS OF DOLLARS ON DEFECTIVE PARTS. BY THE WAY, THIS VEHICLE HAS ALWAYS BEEN SERVICED BY MERCEDES BENZ DEALERSHIP TECHNICIANS. I WOULD APPRECIATE ANY ADDITIONAL INFORMATION OR SUPPORT FROM THE NHTSA AS I PURSUE VIABLE RECOURSE OPTIONS. THANK YOU! *TR

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Most recent recall on file: none. Source: NHTSA Office of Defects Investigation.
