2003 Mercedes-benz Sl-class

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.

I am concerned with the battery control module. I have noticed there has been a lot of incidents out there where the battery control module in the SL 500s have caught fire! I am concerned for my safety due to this defect!

The battery control module (known as the BCM or BNS) failed, triggering a fire. The incident occurred while the vehicle was parked in a garage and had not been operated for several weeks. The fire consumed the module, insulation on wiring connected to and close to the module, part of the trunk lining material, and burned through a total of five hydraulic lines (retractable roof hydraulics). It appears that the trunk seal limited air to the point that the fire was self extinguished. This is the only thing that saved the attached garage and house. The vehicle valued at $30,000 was determined to be a total loss due to the extensive repairs required to restore it to an operating condition. I have since joined a Facebook group "Mercedes BNS/BCM Fires" that has nearly 1000 members and found that this is a common issue with the Mercedes R230 model and fires have occurred dozens if not hundreds of times. We have determined that the module has undergone numerous changes, but there is no confirmation that any are safe. Mercedes refuses to provide guidance or solutions to this issue and apparently has no regard for the safety of current owners. I have retained the failed module, wiring, hydraulic lines, and burned portion of the trunk lining. It is available for inspection or analysis. I am a mechanical engineer with over 35 years experience in the automotive and industrial areas.

The contact owns a 2003 Mercedes-Benz SL500. The contact stated while driving at various speeds, the ABC warning light illuminated. Additionally, the message "Drive Carefully" was displayed. The vehicle was taken to an independent mechanic, where it was diagnosed that the ABC tandem pump, struts, and hoses needed to be replaced. The dealer was notified of the failure and informed the contact that they did not provide service for older vehicles. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 88,000.

It appears the BCM (Battery Control Module) caught fire and burned a significant portion of the trunk and associated wiring.

My car (the SL55 and all SL models) has a "Battery Control Module" (BCM) also referred to as the "Battery Stabilization Control Load Module" which shows signs of imminent failure which will lead to a meltdown or fire. I inspected the module after finding that this was a common problem with these cars online. This model of car has been documented to completely catch on fire, even when parked after driving. I have pictures of the burnt board inside my BCM. I am very concerned as it could literally burn my house down. The typical warning for this issue is a red colored warning on the dash LCD display, however I didn't have that warning as my unit is apparently still functioning even though it's compromised.

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 contact owns a 2003 Mercedes-Benz SL500. The contact stated while driving 40 MPH, the brake pedal was depressed however, the vehicle failed to respond as needed. The contact depressed the brake pedal firmly however, the vehicle failed to respond. The parking brake was activated however, the vehicle failed to respond as designed. The contact was however able to pull over and eventually the vehicle came to a complete stop. The vehicle was towed. The dealer and the manufacturer were contacted and stated that the VIN was not included in NHTSA Campaign Number: 05V133000 (Service Brakes, Hydraulic). The failure mileage was 126,000. The consumer stated the part put on the vehicle for the recall was a defective part and not installed correctly.

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.

The contact owns a 2003 Mercedes-Benz SL500. The contact stated that after parking the vehicle, the following day he noticed that the front of the vehicle was lowered down. The contact stated that the car was too low a warning light was illuminated. The contact stated while starting the vehicle and taking his foot off the brake pedal, the vehicle would raise up independently and would be able to drive to his destination. The contact took the vehicle to the local dealer, where it was diagnosed with needing the front strap suspension to be replaced. The vehicle was repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 52,500.

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 taxes. To divert attention from ABC pump, the dealer is now referring to the problem as "power Steering pump"I have extensively researched the issues and it appears the mentioned problems with my car are prevailing issues with other Mercedes 2003 SL 500, and there are 100's of owners who feel Mercedes is not taking responsibility for replacement and repair of these defective parts under warranty. My car is unsafe to drive. There should be a recall by Mercedes to fix these dangerous to drive cars.

TL* THE CONTACT OWNS A 2003 MERCEDES BENZ SL500. THE CONTACT STATED WHILE DRIVING 45 MPH, THE ACTIVE BODY CONTROL (ABC) WARNING LIGHT ILLUMINATED AND THE STEERING WHEEL BECAME DIFFICULT TO TURN. THE CONTACT PARKED THE VEHICLE ON THE SIDE OF THE ROAD. THE VEHICLE WAS NOT DRIVABLE. THE VEHICLE WAS TOWED TO AN UNKNOWN MERCEDES-BENZ DEALER TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE ACTIVE BODY CONTROL (ABC) NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED HOWEVER, THE FAILURE PERSISTED. THE MANUFACTURER WAS NOT INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 95,000. THE VIN WAS NOT AVAILABLE.

HEARING CLANGING, THUMP NOISE BETWEEN SEATS AND TRUCK, TOOK IT TO A REPAIR SHOP AND WAS ADVISED IT IS A COMMON ISSUE WITH THIS MODEL - PROBLEM WITH BAFFLE IN THE TANK AND MIGHT HAVE COME OFF, SEARCHED ON-LINE AND FOUND HUNDREDS OF COMPLAINTS FOR THE SAME ISSUE, WAS THIS EVER ADDRESSED BY MB AND RECALLED?

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.

SOMETIMES WHEN I START THE CAR THE LIGHTS ON THE DASH WILL NOT COME ON AND NONE OF THE GAUGES WORK ! THEN I TURN IT OFF AND BACK ON AGAIN AND IT WORKS! ALSO WHEN I'M DRIVING AND HIT A LITTLE BUMP ON THE FREEWAY AND ROAD THE DASH LIGHTS TURN RED AND SAYS DRIVE CAREFULLY THEN 2 SECONDS LATER GOES BACK TO NORMAL!

THE ABC SUSPENSION SYSTEM FAILS WHILE DRIVING CAUSING SUSPENSION TO LOWER AND VEHICLE IS DIFFICULT TO HANDLE. THE FRONT END IS SPONGY AND DIPS UP AND DOWN. RED WARNING DO NOT DRIVE ILLUMINATES. VERY UNSAFE.
