06V495000 · Vehicle Speed Control:Accelerator Pedal
Reported: 2006-12-29 (December 29, 2006)
ON CERTAIN VEHICLES, THE ACCELERATOR PEDAL MIGHT NOT HAVE BEEN FULLY FASTENED TO ITS MOUNTING STUDS.
Consequence: OVER TIME, THE PEDAL MAY NOT MAINTAIN A CONSISTENT PEDAL POSITION, WHICH COULD MAKE IT MORE DIFFICULT TO OPERATE THE ACCELERATOR.
Remedy: DEALERS WILL INSPECT AND, IF NECESSARY, INSTALL THE MOUNTING NUTS OF THE ACCELERATOR PEDAL. THE RECALL BEGAN ON JANUARY 16, 2007. OWNERS MAY CONTACT MERCEDES-BENZ AT 1-800-367-6372.

A SOFTWARE CALIBRATION NUMBER (SCN) CODING RECEIVED ON THE AFFECTED VEHICLES DURING A RECENT WORKSHOP VISIT WAS INCORRECT. DEPENDING ON THE MODEL YEAR AND MODEL AFFECTED, THE RESULTS OF AN INCORRECT SCN CODING CAN AFFECT A NUMBER OF VEHICLE SAFETY AND EMISSION FUNCTIONS INCLUDING THE FOLLOWING TYPES OF FUNCTIONS: (1) THE FUEL GAUGE READINGS MAY BE INCORRECT; (2) A STUCK FUEL-LEVEL SENSOR MAY NOT BE DISPLAYED IN THE INSTRUMENT CLUSTER; (3) THE OBD SYSTEM MAY CAUSE THE CHECK ENGINE LIGHT TO ILLUMINATE INCORRECTLY; AND, (4) THE SPEEDOMETER MAY BE OUT OF TOLERANCE.
Consequence: IN THE EVENT OF A VEHICLE CRASH, THE ELECTRICAL FUEL PUMP MAY NOT RECEIVE A CRASH SIGNAL THAT IS REQUIRED FOR THE FUEL PUMP TO DISCONNECT AND PREVENT FUTURE FUEL DELIVERY AS DESIGNED.
Remedy: DEALERS WILL RECODE THE SCN FREE OF CHARGE. THE RECALL BEGAN ON AUGUST 30, 2008. OWNERS MAY CONTACT MERCEDES-BENZ AT 1-800-367-6372.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
2007: 1 complaints · 2009: 1 complaints
