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.
Sep 28, 2022
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.

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.

THE BAFFLE INSIDE THE GAS TANK HAS COME LOOSE AND IS HITTING THE INSIDE OF THE TANK. THE ONLY TIME IT ISN'T NOISY IS WHEN THE TANK IS FULL. AFTER CONTACTING MERCEDES OF UTAH, THEY ADVISED THEY HAVEN'T HEARD OF THE PROBLEM. I DON'T KNOW IF THERE IS A SAFETY ISSUE WITH THE BAFFLE BEING LOOSE BUT IT IS A GREAT CONCERN TO ME. *TR

Aug 03, 2013
MY MERCEDES 2003 SL500 DEVELOPED BANGING NOISE IN THE GAS TANK, IN JANUARY 2010 , HAVING ABOUT 18,000 MILES, PROMPTING ME TO CALL THE DEALER. I WAS TOLD THAT THE BAFFLE BROKE OFF AND COULDN'T BE FIXED, ADVISING ME TO REPLACE THE TANK FOR $2,500. I ARGUED THAT IT WAS AN OBVIOUS MANUFACTURING DEFECT CONSIDERING THE LOW MILES AND REQUESTED A FREE TANK REPLACEMENT, BUT I WAS REFUSED ON THE GROUNDS THAT THE WARRANTY EXPIRED. I COULDN'T BELIEVE WHAT I HEARD, DID SOME RESEARCH AND DISCOVERED THAT EARLY MODELS IN 2003 AND 2004, HAD SIMILAR TANK PROBLEMS AND WERE REPLACED WITH A BETTER DESIGN LATER. BUT, I WAS NOT INFORMED ABOUT IT. FURTHERMORE, I FOUND OUT THAT MANY OTHER OWNERS FROM THAT TIME HAD THE SAME PROBLEM AS I DID. I WAITED FOR A WHILE TO SEE IF MERCEDES CORPORATION WOULD RECALL THE EARLY MODELS, KEPT THE GAS TANK FULL TO AVOID THE ANNOYING NOISE (THE BROKEN BAFFLE CANNOT FLOAT AND BANG WHEN THE TANK IS FULL) AND WHEN I GOT CONVINCED THAT MERCEDES WOULD NOT DO ANYTHING FOR THE VICTIMS I DECIDED TO FILE THIS COMPLAINT. IT IS A SHAME THAT A MANUFACTURER WOULDN'T WANT TO CORRECT THEIR OWN MISTAKES, CONSIDERING A $100,000 PRICE TAG THAT I PAID. WHAT HAPPENED TO THAT GERMAN QUALITY AND ETHICS? THEY CERTAINLY LOST THIS CUSTOMER FOR GOOD.

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!
Nov 27, 2023
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.

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

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!

FUEL/PROPULSION SYSTEM
8 complaints
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.

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?
Jul 06, 2020
HERE A BANGING NOISE BEHIND THE SEAT, TOOK IT TO A MERCEDES BENZ REPAIR SHOP. THEY INFORMED ME THE FUEL TANK BAFFLE IS BROKEN FREE. HE SAID IT IS VERY COMMON ON THIS MODEL. BUT NOT COVERED UNDER WARRANTY OR RECALL. IT WOULD CONT ME OVER 2,500.00 TO REPAIR. DOING SOME RESEARCH ONLINE AT MBWORLD FORUM. THIS HAPPEN ON ALMOST EVERY CAR LIKE THIS. I CAN NOT AFFORD TO FIX THIS. AND I AM WORRIED THIS MIGHT BLOW UP OR SOMETHING, SINCE SOMETHING BANGING AROUND THE THE INSIDE OF THE FUEL TANK CAN NOT BE SAFE, THIS CAR RUNS ON PREMIUM GASOLINE. IT SEEMS TO HAPPEN LOUDER WHEN THE TANK IS FROM 3/4 FULL TO 1/2. IF I LET IT RUN TO LOW THE FUEL GAUGE STICKS ON EMPTY UNTIL I GO OVER A BIG BUMP. I BELIEVE THIS IS A FACTORY DEFECT AS THE CAR ONLY HAS 60,000 MILES ON IT. I SHOULD NOT HAVE TO REPLACE THE FUEL TANK ON A CAR THAT COST ABOUT 100,000.00 NEW. BUT MORE IMPORTANT, I DO NOT FEEL THIS CAR IS SAFE TO DRIVE IN THIS CONDITION. THE DEALER STATED IT IS NOT A SAFETY ISSUE, JUST AN ANNOYANCE???

TL* THE CONTACT OWNS A 2003 MERCEDES BENZ SL500. WHILE DRIVING AT VARIOUS SPEEDS, AN ABNORMAL NOISE COULD BE HEARD IN THE VEHICLE.

I FILED THIS COMPLAINT MONTHS AGO AND HAVEN'T HEARD A WORD. THE ISSUE IS THE GAS TANK BAFFLE HAS APPARENTLY COME LOOSE FROM INSIDE THE TANK AND IS CREATING A BANG IN THE TANK VEHICLE IS SLOWING DOWN AND STOPPING. THERE WAS NO ACCIDENT. MERCEDES SAID THEY HAVEN'T HEARD OF THIS PROBLEM BUT IN RESEARCH THIS IS A PROBLEM WITH 2003-2004 SL500. IS THERE A SAFETY PROBLEM WITH THIS BAFFLE BEING LOOSE IN THE TANK? AND WHY ISN'T THERE A RECALL? *TR

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.
Mar 29, 2017
I HAVE A 2003 MERCEDES SL500 WITH 52000 MILES ON IT AND SUDDENLY THE BRAKE WARNING LIGHT CAME UP AND THE INVESTIGATION LINKED IT TO THE SBC HYDRAULIC RECALL (2005070007). MERCEDES HAD EXTENDED THE WARRANTY ON SBS UNIT FOR 10 YEARS AND MY CAR IS NOW OUT OF THAT EXTENDED WARRANTY PERIOD. THE SBC ISSUE DID NOT OCCUR UNTIL THE CAR HAD OVER 51000 MILES. I REACHED OUT TO MERCEDES BENZ CUSTOMER CARE AND THEY WANTED ME TO TAKE THE CAR TO THE AUTHORIZED DEALER WHICH I DID AND THE DEALER'S REPORT CLEARLY STATES THAT THEY COULD NOT CONNECT TO THE SBC PUMP AND IT NEEDS TO BE REPLACED IMMEDIATELY. MERCEDES BENZ CUSTOMER CARE CALLED ME BACK STATING THAT THE CAR IS OUT OF THE 10 YEAR WARRANTY PERIOD AND DOES NOT QUALIFY FOR THE REPLACEMENT. AS A MATTER OF FACT, I WAS TOLD THAT THERE WAS NO RECALL ON THE ENTIRE SBC PUMP AND ALSO STATED THAT IT WAS ONLY ON THE INSTALLATION OF BRACKET, WHICH HAPPENS TO BE ANOTHER RECALL ON THE SBC UNIT (2005110001). THE VEHICLE DOES NOT ADEQUATELY STOP DUE TO THIS FAILURE AND THE REPAIR COST TO REPLACE THE SBC UNIT AS STATED BY THE DEALER IS $1939.75. THIS IS CLEARLY A SAFETY RECALL THAT IS A CONCERN AND SO WOULD LIKE TO REQUEST NHSTA TO ADVISE.

TL* THE CONTACT OWNS A 2003 MERCEDES BENZ SL500. THE CONTACT STATED THAT WHILE DRIVING 45 MPH, HE ATTEMPTED TO ENGAGE THE BRAKES BUT THE PEDAL SANK TO THE FLOORBOARD ABNORMALLY.

ALSO, THEY ADVISED THAT THE BRAKE HYDRAULIC UNIT NEEDED TO BE REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 224,679.

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.

PLASTIC PIECE ON GEARSHIFT ASSEMBLY BROKE NOT ALLOWING CAR TO BE PLACED IN GEAR. IS APPARENTLY A PROBLEM WITH 1000'S OF THESE CARS BASED ON INTERNET SEARCH. CONTACTED MERCEDES AND THEY SAID NOT THEIR PROBLEM. THEY CHARGE $1300.00 TO FIX THE PROBLEM. THEY STATED TO SAVE MONEY ON THIS PART BEING REPLACED TO TAKE A MALLET AND FINISH BREAKING PIECE THEREBY RENDERING CHILD SAFETY FEATURE USELESS. APPARENTLY LOOKING AT THE INTERNET THIS IS WHAT 1000'S OF PEOPLE HAVE ALREADY DONE. HOW MERCEDES THINKS THIS IS A NOT A SAFETY CONCERN IS BEYOND ME. IT IS AN EXTREMELY DANGEROUS SITUATION TO ALL CHILDREN AS THEY WILL BE ABLE TO PUT CAR INTO GEAR WITH NO SAFETY PRECAUTIONS. I CAN SEE MANY CHILDREN EVENTUALLY PUTTING THESE CARS IN GEAR AND GETTING HURT.

OUR 2003 MERCEDES-BENZ SL500 BECAME STUCK IN PARK AND COULD NOT GET OUT OF PARK DESPITE A VARIETY OF RECOMMENDED ATTEMPTS (TURNING KEY TO ON BUT NOT STARTING AND PUMPING BRAKES, ETC.). IT WAS TOWED TO THE DEALERSHIP AND IS CURRENTLY BEING REPAIRED FOR ABOUT $1300. FROM RESEARCHING ON THE INTERNET I SEE THIS IS A COMMON PROBLEM WITH THIS MODEL CAR AND MAY BE DUE TO A SINGLE PLASTIC PART IN THE SHIFTER WHICH IS ASSOCIATED WITH THE VEHICLE ANTI-THEFT SYSTEM (INTERLOCK?). APPARENTLY THE REPLACEMENT PART IS HEAVIER DUTY - MAY BE ALUMINUM NOT PLASTIC (?). NOT SURE WHY THE WHOLE SHIFTER NEEDS REPLACING VS. THE SINGLE PLASTIC PART. *TR

THIS VEHICLE IS EQUIPPED WITH SENSOTRONIC BRAKE CONTROL THAT HAS A SERVICE THRESHOLD. WHEN THIS THRESHOLD IS REACHED THE BRAKE SYSTEM DEFAULTS TO NON POWER ASSISTED HYDRAULIC MODE TO THE FRONT WHEELS ONLY. THIS OCCURS WITHOUT ANY PRIOR WARNING AND RESULTS IN INCREASED STOPPING DISTANCE. I HAVE SENT A COPY OF THE MERCEDES SERVICE BULLETIN S142.46-P-0012A WHICH ADDRESSES THIS ISSUE. MERCEDES STOPPED INSTALLING THIS SYSTEM IN 2006. AT THE VERY LEAST, MERCEDES SHOULD ISSUE A MANDATORY RECALL TO INTERROGATE THESE VEHICLES WITH STAR DAS TO DETERMINE HOW CLOSE TO THE SERVICE THRESHOLD THE SBC UNIT IS AND REPLACE THEM AT THE DEALER'S EXPENSE. THIS IS A MAJOR SAFETY ISSUE THAT NEEDS TO BE ADDRESSED EVEN IF THE AUTOMOBILE IS OLDER

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.

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

DRIVING ALONG ON 2/14/2015, I HEAR A BANGING COMING FROM THE BACK OF THE CAR. I NOTICE IT ONLY DOES IT WHEN I AM EXCELLING OR BRAKING. I THOUGHT THERE MAY BE SOMETHING IN THE TRUNK, LIKE A LIQUID WITH SOMETHING FLOATING IN IT, BANGING UP AGAINST THE SIDE OF THE CONTAINER. AFTER I PARKED, I CHECKED OUT THE BOX THAT I HAVE PUT IN THE BACK OF MY CAR. THERE WAS NOTHING THERE THAT WOULD MAKE THIS NOISE. UPON FURTHER INVESTIGATION, I SEE THAT THERE MANY COMPLAINTS AGAINST THE BAFFLE THAT IS INSIDE THE GAS TANK THAT COMES LOSE AND BANGS THE SIDES OF THE GAS TANK. THIS IS NOT ACCEPTABLE. I WILL TAKE MY CAR TO THE SHOP ON TUESDAY AND SEE ABOUT REPAIRS AND HAVING MB PAY FOR IT. *TR

2003 MERCEDES BENZ SL 500. CONSUMER WRITES IN REGARDS TO POSSIBLE FATAL FLAW IN VEHICLE. *SMD THE CONSUMER STATED, AS HE WAS BACKING OUT OF HIS DRIVEWAY, HE APPLIED THE BRAKE AND THEY FAILED. A RED LIGHT AND A SIGN INSTRUCTED HIM TO OBTAIN IMMEDIATE SERVICE. THE MECHANIC, KEPT THE VEHICLE FOR A WEEK, BUT WAS UNABLE TO ANYTHING WRONG WITH THE BRAKES. AT THE MECHANIC'S SUGGESTED, THE VEHICLE WAS TOWED TO THE DEALER. AFTER THE VEHICLE WAS THERE FOR A FEW DAYS, THE DEALERSHIP CALLED AND SAID THE PROBLEM WAS THE BATTERY HAD DIED. IT WAS A SECONDARY BATTERY WHICH SUPPLIED POWER TO EVERYTHING THAT CONSUMED ELECTRICITY, INCLUDING THE BRAKES IN HIS MODEL AND YEAR VEHICLE. SO, IF IT FAILED, SO WOULD THE BRAKES. *JB

I OWN A 2003 MERCEDES BENZ SL500. LIKE MOST OWNERS OF THIS VEHICLE, THE BAFFLE MOVES FREELY WITHIN THE GAS TANK WHICH CAUSES A NOISE AND IS POTENTIAL DANGEROUS IF A SPARK IS CREATED FROM THE BAFFLE HITTING THE INSIDE WALLS OF THE GAS TANK. FROM MY RESEARCH IT IS A MANUFACTURE ISSUE WITH THE WELDING OF THE BAFFLE TO THE INTERNAL WALL OF THE GAS TANK. THERE IS A TREMENDOUS AMOUNT OF COMPLAINTS AND THREADS ON MERCEDES FORUMS. PLEASE FOLLOW LINK TO SEE ALL COMPLAINTS. IT IS POOR CUSTOMER SERVICE AND ACCOUNTABILITY FROM MERCEDES BENZ USA TO NOT RECALL THE ISSUE. THERE IS OVER 20 PAGES OF COMPLAINTS REGARDING THIS ISSUE AT THIS LINK: HTTP://WWW.BENZWORLD.ORG/FORUMS/R230-SL-CLASS/1295215-SL500-NOISE-REAR-INTERIOR-WALL-GAS.HTML. *TR

WHILE DRIVING TO WORK, I WAS GOING ABOUT 35 MPH WHEN THE DASH LIGHTS UP RED SAYING "SERVICE BRAKES, STOP VEHICLE, ETC". MY MECHANIC LOOKED OVER EVERYTHING TO DO WITH BRAKES AND COULD NOT FIX IT. HE CALLED MERCEDES OF TALLAHASSEE AND WAS TOLD IT WAS AN ELECTRICAL ISSUE THAT WAS A COMMON PROBLEM WITH THIS VEHICLE. IT DID HAVE A RECALL ON IT, BUT IT EXPIRED IN JULY LAST YEAR, JUST MY LUCK. SO I GOOGLED IT AND HAVE NOW FOUND TONS OF PEOPLE WITH THE SAME EXPERIENCE! HOW CAN THE VEHICLE SAFETY ADMINISTRATION LEGALLY ALLOW MERCEDES BENZ TO CONTINUE LETTING THIS HAPPEN TO PEOPLE? HOW MANY ACCIDENTS MUST TAKE PLACE, OR GOD FORBID DEATHS BEFORE SOMETHING IS DONE? I HAVE NO OPTION BUT TO PAY OUT OF POCKET TO HAVE THIS PIECE OF $100K JUNK FIXED AND PRAY IT NEVER HAPPENS AGAIN! MERCEDES BENZ AND THE VEHICLE SAFETY ADMINISTRATION BETTER PRAY THIS DOESN'T CAUSE AN ACCIDENT OR I WILL SUE THE [XXX] OUT OF BOTH!

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

I PURCHASED MY SL500 USED, WITH ONLY 29,000 MILES ON IT, DIRECTLY FROM RUSNAK MERCEDES IN ARCADIA, CA. SERVICE HAS BEEN BEYOND POOR SINCE DAY 1. MY CURRENT PROBLEM IS AN OBNOXIOUS BANGING THAT COMES FROM BEHIND THE HEAD. I CALLED RUSNAK ABOUT THIS AND THE LADY WAS VERY FIRM TELLING ME IT'S NOT A RECALL, ALTHOUGH I'D READ LOTS OF COMPLAINTS ONLINE ABOUT THE SAME PROBLEM. SO I TOOK IT TO A LOCAL GARAGE- AFTER A WEEK OF LABOR THEY FIND IT'S A HOLE IN THE GASTANK, $2000 TO REPAIR. I DO NOT UNDERSTAND WHY THIS HAS NOT BEEN RECALLED. EVERYTHING I'VE READ HAS SAID THIS IS A COMMON PROBLEM, ALL IN 2003 SL500S AROUND 60,000 MILES. HOW CAN MERCEDES IGNORE THIS?
