WHENEVER MY CAR FILLED UP (NOT OVER FILL) WITH GASOLINE, THE STRONG GASOLINE SMELL WILL LAST A FEW DAYS. THE CAR WAS INVESTIGATED BY MERCEDES DEALER, THEY FOUND FUEL PUDDLED AT SENDER UNDERNEATH THE REAR SEAT ON LEFT SIDE. THEY STATED THAT THE CAR IS NOT SAFE FOR USE AT THIS TIME DUE TO FIRE HAZARD. HOWEVER, THEY WON'T FIX IT AS MANUFACTURE DEFECT AND WOULD CHARGE ME FOR $1,300.00 AND I DIDN'T REPAIR IT SINCE IT IS TOO EXPENSIVE. I ALSO THE FUEL SENDING UNIT IS NOT THE PART THAT NEED REGULAR SERVICE AND SHOULD NOT BE WARE OUT. MERCEDES BENZ NEED TO ISSUE A RECALL ON THIS PROBLEM. *TR

I'M WRITING TO LODGE A COMPLAINT CONCERNING A DANGEROUS FUEL LEAK INTO THE CABIN OF MY PARENTS' 2006 MERCEDES BENZ E 350 (VIN [XXX]), WHICH HAS RESULTED IN GAS SOAKING THE REAR INSULATION PAD, SOUND PAD, & REAR SEAT CUSHION, ALL OF WHICH ARE "SOAKED" IN GAS (PER THE REPAIR RECOMMENDATION FROM MB OF SAN DIEGO). I SHOULD ADD THAT THE CAR ONLY HAS ABOUT 55K MILES. MY MOM IS 76 AND MY DAD IS 82. THEY DON'T DRIVE MUCH-- JUST LOCAL ERRANDS. THE ONLY REASON MY MOM CAUGHT THIS ONE WAS THE STRONG GAS SMELL IN THE CABIN. I AM WRITING TO YOU DIRECTLY FOR THE FOLLOWING REASONS: 1.THIS RELATES TO YOUR ON-GOING INVESTIGATION #PE12-001. 2.THE FUEL LEAK PRESENTS A DANGEROUS RISK OF FIRE AND RISK OF GAS FUME INHALATION TO THE DRIVER AND PASSENGERS. 3.THE FUEL FROM THE LEAK DOES IN FACT SOAK INTO REAR INSULATION PAD, SOUND PAD, & REAR SEAT CUSHION, DESPITE THE INCORRECT DENIAL OF THAT FACT BY MB-USA TO THE NHTSA. (SEE LETTER FROM MB-USA TO YOU.) 4.THE SERVICE ADVISOR AT MB OF SAN DIEGO TOLD ME LAST WEEK THAT HE HAS PERSONALLY SEEN A LOT OF THESE FUEL LEAKS INTO THE CABIN WITH MBS. I HAVE ASKED THE DEALER PERFORMING THE REPAIR TO SAVE THE DEFECTIVE THE PART(S) AND THE SOAKED INSULATION PAD, SOUND PAD, & REAR SEAT CUSHION.

THIS ISN'T A COMPLAINT, IT IS A REQUEST FOR CONSIDERATION OF OR ASSISTANCE FOR THE REPLACEMENT OF THE GASOLINE TANK FOR MY VEHICLE. WHEN I TOOK OWNERSHIP FROM THE PREVIOUS OWNER, THE FIRST TIME I FILLED UP THE GAS TANK, THE VEHICLE WAS EMITTING A STRONG GASOLINE ODOR. I TOOK THE VEHICLE TO THE MERCEDES BENZ CERTIFIED SERVICE REPRESENTATIVE HERE BECAUSE THIS IS WHERE THE PREVIOUS OWNER ALWAYS HAD THIS VEHICLE SERVICED. THERE WERE NO RECORDS SHOWING THIS PROBLEM BEING LOOKED INTO, AND WHEN I ASKED THE PREVIOUS OWNER, HE SAID HE NEVER FILLED UP THE GASOLINE TANK, ALWAYS PUTTING IN $15 - $20 OR SO AT A TIME, THEREFORE HE NEVER SMELLED THE GASOLINE ODOR. THE MERCEDES BENZ CERTIFIED SERVICE REPRESENTATIVE INFORMED ME THAT THIS MODEL ALONG WITH 2005 AND 2007 MODELS HAD SIMILAR PROBLEMS WITH THE GASOLINE TANKS. I THEN TOOK IT TO OUR MERCEDES BENZ DEALERSHIP HERE AND TALKED WITH A SERVICE REPRESENTATIVE. HE WAS VERY, VERY HELPFUL, VERY KNOWLEDGEABLE, AND TOLD ME THERE WERE PROBLEMS WITH THIS ISSUE ON THESE MODELS, BUT NO VEHICLES HAD BEEN RECALLED. HE TOLD ME HOW MUCH IT WOULD COST TO HAVE THE GASOLINE TANK REPLACED (WORSE CASE SCENARIO) SUGGESTED I WRITE TO YOU AND SEE IF YOU WOULD CONSIDER REPLACEMENT OR ASSISTANCE. IT IS MY FIRST MERCEDES BENZ TO OWN AND I LOVE THIS VEHICLE. I AM A RETIRED MINISTER LIVING ON SOCIAL SECURITY, SO ANYTHING YOU COULD DO FOR ME WOULD BE PRAYERFULLY APPRECIATED. WOULD YOU MIND LOOKING INTO THIS AND ASSIST ME WITH THIS PROBLEM? THANK YOU VERY MUCH. *TR *JS

PE10017 · Driver Air Bag Circuit High Resistance

Opened May 14, 2010 · Closed Nov 24, 2010

Status: closed (inferred from source dates) · Air Bags; Air Bags:frontal; Electrical System; Electrical System:wiring; Electrical System:wiring:interior/under Dash

Mercedes-Benz USA (MBUSA) has reported a high number of warranty claims for air bag warning lamp illumination due to a diagnostic fault code 9103 or 9123 indicating a high resistance in the driver's frontal air bag firing circuit.MBUSA's testing and evaluation have shown that this condition is the result of a faulty connector (specifically, improper wire crimp) but that it will not prevent proper deployment of the driver's frontal air bag.The faulty connector can cause the air bag circuit resistance levels to exceed the threshold that illuminates the air bag warning lamp, but they do not exceed a higher limit at which proper deployment of the air bag may no longer occur.The agency believes that further expenditure of agency resources does not appear to be warranted at this time.The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.The agency will monitor the issue and reserves the right to take future action if warranted by the circumstances.During the investigation, ODI learned that MBUSA will initiate a warranty extension program to address the faulty connectors in subject model year 2005 and 2006 E-Class and other MBUSA model/model year vehicles.This action will extend the warranty coverage for this issue to 10 years or 100,000 miles, whichever occurs first.MBUSA will notify all affected vehicle owners of this action.A bulletin describing this program is available in the investigative file.
