MY AIRBAGS SELF DEPLOYED WHILE I WAS DRIVING. I HAD JUST LEFT WORK AND DRIVING NORTHBOUND ON THE WEST SAM HOUSTON TOLLWAY APPROACHING THE TOLL STATION AT HIGHWAY SPEEDS. THERE WAS AN INCREDIBLY LOUD EXPLOSION AND AND HARD PERCUSSION AS THE AIRBAGS SELF DEPLOYED WHILE I WAS DRIVING. I THOUGHT I HAD BEEN PUNCHED OR SHOT IN THE GUT. THE PASSENGER SIDE CURTAIN DROPPED DOWN AND THE RIGHT REAR PASSENGER SIDE DOOR BAG DEPLOYED. THE SEATBELT AROUND MY WAIST AND SHOULDER TIGHTENED. FORTUNATELY, I KEPT IT TOGETHER AND DROVE DIRECTLY TO THE DEALERSHIP. I HAD NOT HIT ANYTHING, RUN OVER A POTHOLE, SWERVED OR OTHERWISE MAKE ANY SUDDEN DIRECTION CHANGE. I WAS IMMEDIATELY CALLED BY AN OPERATOR ON THE MERCEDES EMERGENCY SYSTEM WITHIN THE CAR. SO MERCEDES IS AWARE OF THE INCIDENT AT THE TIME IT HAPPENED. SHE ASKED IF I NEEDED AN AMBULANCE OR POLICE. I TOLD HER THAT THE AIRBAGS HAD DEPLOYED ON THEIR OWN AND THAT I WAS PHYSICALLY OK. ADDITIONALLY, I DROVE IMMEDIATELY TO STAR MOTOR DEALERSHIP WHERE THEY LOOKED AT MY VEHICLE LESS THAN 20 MINUTES AFTER IT OCCURRED. THE SERVICE ADVISER AND SOME OF THE TECHNICIANS QUICKLY LOOKED AT THE VEHICLE (IT WAS NEAR CLOSING TIME). THEY SAID THEY COULD NOT READ THE CODES OTHER THAN THE SRS FAULT. I WAS ADVISED THAT IT WOULD LIKELY BE CHEAPER TO FIX AT A BODY SHOP THAN AT THE DEALER. I LATER FOUND THAT THE DRIVER SIDE REAR SEATBELT HAD ALSO DEPLOYED AND WAS TIGHTENED.

ON DECEMBER 28 2006 I TOOK MY 2003 MERCEDES BENZ E320 TO MERCEDES BENZ OF MANHATTAN BECAUSE THE SRS (SAFETY RESTRAINT SYSTEM) LIGHT CAME ON IN THE DASHBOARD. THE TECHNICIANS DETERMINED THAT THE SRS CONTROL UNIT WAS MALFUNCTIONING AND NEEDED TO BE REPLACED. THE SRS CONTROL UNIT IS RESPONSIBLE FOR DEPLOYING THE AIR BAGS AND TENSIONING THE SEAT BELTS IN CASE OF AN ACCIDENT. I PURCHASED MY CAR USED FROM A NISSAN DEALERSHIP WITH A BUMPER TO BUMPER EXTENDED WARRANTY FROM QUALITYGUARD PLUS 615-725-1000 POLICY #QSDL01651641 EXPIRES: 07-01-2007. THE WARRANTY COMPANY WAS INFORMED OF THE ABOVE, BUT REFUSED TO PAY FOR REPAIRS CLAIMING THAT THE PART WAS NOT COVERED UNDER THE WARRANTY. I ASKED THEM WHY, AND THEY JUST REPEATED, ITS NOT COVERED. I THINK I DESERVE A BETTER ANSWER THAN THAT, ESPECIALLY WHEN IT COMES TO MY PERSONAL SAFETY AND THE SAFETY OF MY FAMILY. I THINK IT SHOULD BE COVERED. YOU ASSISTANCE WITH THIS MATTER WOULD BE APPRECIATED. *NM

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.
