Jul 7, 2008 · NHTSA campaign 08V303000 · 404 vehicles

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.

Engine

Jan 9, 2008 · NHTSA campaign 08V006000 · 9,004 vehicles

Problem: On certain passenger vehicles equipped with diesel engines, the crankshaft sensor could fail due to separation of bond wires from the lead frame in the sensor. This results in an interruption in the electrical connection in the chip housing of the sensor.

Original NHTSA wording

ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH DIESEL ENGINES, THE CRANKSHAFT SENSOR COULD FAIL DUE TO SEPARATION OF BOND WIRES FROM THE LEAD FRAME IN THE SENSOR. THIS RESULTS IN AN INTERRUPTION IN THE ELECTRICAL CONNECTION IN THE CHIP HOUSING OF THE SENSOR.

Risk: When this happens, the vehicle May lose power rather than enter a limp-home mode. In addition, the vehicle cannot be restarted after failure of the electrical connection in the sensor, increasing the risk of a crash.

Original NHTSA wording

WHEN THIS HAPPENS, THE VEHICLE MAY LOSE POWER RATHER THAN ENTER A LIMP-HOME MODE. IN ADDITION, THE VEHICLE CANNOT BE RESTARTED AFTER FAILURE OF THE ELECTRICAL CONNECTION IN THE SENSOR, INCREASING THE RISK OF A CRASH.

Remedy & notes

Dealers will replace the crankshaft sensor. The recall began on February 4, 2008. Owners May contact Mercedes-Benz at 1-800-367-6372.

Seat Belts

Apr 3, 2006 · NHTSA campaign 06V101000 · 2,500 vehicles

Problem: On certain passenger vehicles, during the production process, the threads in the nut used to secure the seat belt buckle in a limited number of second row seats May be missing. The absence of the screw threads results in an incomplete connection of the buckle to the seat.

Original NHTSA wording

ON CERTAIN PASSENGER VEHICLES, DURING THE PRODUCTION PROCESS, THE THREADS IN THE NUT USED TO SECURE THE SEAT BELT BUCKLE IN A LIMITED NUMBER OF SECOND ROW SEATS MAY BE MISSING. THE ABSENCE OF THE SCREW THREADS RESULTS IN AN INCOMPLETE CONNECTION OF THE BUCKLE TO THE SEAT.

Risk: In the event of a crash, a seat occupant May not be properly restrained increasing the risk of personal injury.

Original NHTSA wording

IN THE EVENT OF A CRASH, A SEAT OCCUPANT MAY NOT BE PROPERLY RESTRAINED INCREASING THE RISK OF PERSONAL INJURY.

Remedy & notes

Electrical System

Apr 3, 2006 · NHTSA campaign 06V098000 · 7,000 vehicles

Problem: On certain passenger vehicles, the starter wiring harness May be routed incorrectly. This routing could lead to chafing of the protective sleeve covering the starter wiring harness at the engine mount cover.

Original NHTSA wording

ON CERTAIN PASSENGER VEHICLES, THE STARTER WIRING HARNESS MAY BE ROUTED INCORRECTLY. THIS ROUTING COULD LEAD TO CHAFING OF THE PROTECTIVE SLEEVE COVERING THE STARTER WIRING HARNESS AT THE ENGINE MOUNT COVER.

Risk: Over time, such chafing has the potential to wear through the protective sleeve and May expose the underlying starter wiring harness to further chafing, which could result in an electrical short, and the loss of function of the vehicle's electrical system.

Original NHTSA wording

OVER TIME, SUCH CHAFING HAS THE POTENTIAL TO WEAR THROUGH THE PROTECTIVE SLEEVE AND MAY EXPOSE THE UNDERLYING STARTER WIRING HARNESS TO FURTHER CHAFING, WHICH COULD RESULT IN AN ELECTRICAL SHORT, AND THE LOSS OF FUNCTION OF THE VEHICLE'S ELECTRICAL SYSTEM.

Remedy & notes

Dealers will inspect and where necessary, correct, the routing of the wiring harness. In the case of wear, the protective sleeve, and if necessary, the starter wiring harness, will be replaced. The recall began on May 12, 2006. Owners May contact Mercedes-Benz at 1-800-367-6372.

Mercedes-Benz recall no. 2006040002.customers May also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (tty 1-800-424-9153), or go to http://www.safercar.gov.
