IMMEDIATELY AFTER PURCHASE, NOTICED A CONSIDERABLE FRONT NOSE DROP WHILE DRIVING ISSUE REPEATED FREQUENTLY WHILE DRIVING. OVERNIGHT, THE VEHICLE WOULD DROP 3-4 INCHES. TOOK VEHICLE TO REPAIR SHOP AND WATCHED AS VEHICLE "BUCKED UP AND DOWN" AS IF IN A LOW-RIDER SHOW. MECHANIC STATED IT WAS A COMMON OCCURRENCE AND RECOMMENDED CHANGING SENSORS. VEHICLE TAKEN TO MERCEDES DEALER WITH COPY OF RECALL NOTICE 08V405000. DEALER REPLACED LEFT FRONT STRUT ($1500) INSTEAD, STATING MY VEHICLE IS NOT PART OF THIS RECALL. STRUT REPLACEMENT ELIMINATED THE 3-4 INCH OVERNIGHT DROP, BUT THE NOSE DROP DURING DRIVING WAS NOT FIXED. DEALER NOW WANTS TO REPLACE THE ABC SENSORS ($1200-$1500). TO DATE, 3 OF 4 STRUTS/SHOCKS HAVE BEEN REPLACED. CAR IS IN AN UNSAFE CONDITION. NUMEROUS POSTS ON INTERNET REGARDING THIS ISSUE! PLEASE HELP. *TR

WE WERE DRIVING 65MPH ON THE HIGHWAY WHEN SUDDENLY OUR 2003 MB 500SL BECAME ERRATIC WITH THE SUSPENSION DROPPING DOWN ON THE DRIVER'S SIDE. I WAS FORCED TO QUICKLY PULL OFF THE HIGHWAY. IT WAS A TERRIFYING EXPERIENCE AND WE WERE EXTREMELY LUCKY TO PULL OVER RIGHT AWAY WITHOUT HITTING OTHER CARS. THE CAR WAS VERY LOW TO THE GROUND ON ONE SIDE. AFTER RESTARTING THE CAR, THE SUSPENSION IMPROVED ENOUGH TO GET US HOME. ON MY DRIVE TO THE DEALERSHIP THE CAR WAS VERY LOW EVERYWHERE FORCING ME TO DRIVE 35MPH AND IT BOTTOMED OUT ON A BUMP ON THE HIGHWAY. THE DEALERSHIP INFORMED US THAT THE ABC SYSTEM PUMP HAD FAILED AND THE CAR ADDITIONALLY HAD LEAKING REAR SHOCKS. OUR CAR HAS LOW MILEAGE AND VERY LITTLE WEAR. THE DEALERSHIP QUOTED $7600 TO INSTALL A NEW PUMP, FLUSH OUT AND REPLACE THE HYDRAULIC FLUID AND INSTALL NEW REAR SHOCKS! THEY STATED THAT THIS MAY NOT COMPLETELY FIX THE ABC PROBLEM AS ADDITIONAL DAMAGE MAY HAVE OCCURRED FROM THE FAILED PUMP AND DEBRIS IN THE SYSTEM. THIS IS OUTRAGEOUS! THERE IS CLEARLY AN ONGOING AND VERY PREVALENT AND DANGEROUS DEFECT WITH THE MERCEDES BENZ ABC SYSTEM, AS IT IS HAPPENING TO SO MANY VEHICLES. THERE MUST BE A RECALL ON THESE VEHICLES. THIS IS A VERY SERIOUS PROBLEM WHICH COULD EASILY RESULT IN MULTIPLE HIGHWAY FATALITIES. MERCEDES BENZ HAS TO TAKE RESPONSIBILITY FOR THEIR DEFECTIVE SYSTEM BEFORE SOMEONE IS KILLED. *TR

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.
