2004 Mercedes-Benz S Class

Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

The defect: ON CERTAIN VEHICLES, THE INSTRUMENT CLUSTER IS EXPERIENCING ELECTRICAL MALFUNCTIONS. THE INSTRUMENT CLUSTER CONTAINS GAUGES AND INDICATORS THAT MUST BE ILLUMINATED WHENEVER THE VEHICLE IS IN OPERATION.
The risk: DUE TO INADEQUATE ILLUMINATION, THE DRIVER WILL BE UNABLE TO READ THE GAUGES AND INDICATORS, SUCH AS THE SPEEDOMETER, WHICH COULD INCREASE THE RISK OF A CRASH.
The remedy: DEALERS WILL REPLACE THE INSTRUMENT CLUSTER MODULES. THE RECALL WILL BE CONDUCTED IN PHASES. PHASE I WAS MAILED OUT TO APPROXIMATELY 7,500 OWNERS ON SEPTEMBER 29, 2006. PHASE II AND PHASE III IS SCHEDULED FOR DECEMBER 2006. OWNERS MAY CONTACT MERCEDES-BENZ AT 1-800-367-6372.

AIR SUSPENSION SYSTEM FAILURE

Opened Aug 14, 2007
Closed Nov 20, 2007

THE SUBJECT S-CLASS VEHICLES CONTAIN A COMPRESSED AIR SUSPENSION SYSTEM THAT USES AIR STRUTS ON EACH OF THE FOUR WHEELS IN LIEU OF TRADITIONAL SPRINGS AND SHOCK ABSORBERS.THESE AIR STRUTS USE COMPRESSED AIR TO SUPPORT THE WEIGHT OF THE VEHICLE AND CONTROL RIDE HEIGHT.IN THE EVENT OF THE LOSS OF AIR FROM THE SYSTEM, AN ALERT WILL FLASH ON THE INSTRUMENT CLUSTER WARNING THE DRIVER TO EITHER DRIVE CAREFULLY OR TO STOP THE VEHICLE.THE VEHICLE RIDE HEIGHT CAN BE REDUCED BY AS MUCH AS 105 MM BELOW NORMAL RIDE HEIGHT BEFORE THE FULL LOAD OF THE VEHICLE FOR THAT WHEEL COMES TO REST ON A STEEL ROD, WITH A RUBBER STOP ON THE END, LOCATED IN THE SHOCK ABSORBER.THIS REST-STOP CONDITION IS DESIGNED SUCH THAT THERE IS NO IMPACT ON VEHICLE CONTROL.MERCEDES-BENZ (MBUSA) SUPPLIED VIDEO SHOWING A VEHICLE IN THIS CONDITION OPERATING UNDER SEVERAL DIFFERENT SITUATIONS INCLUDING EVASIVE MANEUVERS DEMONSTRATING THE ABILITY OF THE VEHICLE TO BE CONTROLLED EFFECTIVELY WITH A RIDE HEIGHT REDUCED TO THE MINIMUM.ONLY THOSE COMPLAINTS TO ODI AND MBUSA THAT ALLEGED A STEERING INTERFERENCE DURING A REDUCED RIDE HEIGHT CONDITION WERE COUNTED IN THIS RESUME FAILURE REPORT.SOME COMPLAINTS ALLEGED THAT WITH A REDUCED RIDE HEIGHT AND A STOP NOW WARNING MESSAGE THERE WAS A RUBBING NOISE WHEN TURNING, BUT THE ABILITY TO STEER THE VEHICLE WAS NOT COMPROMISED.A SAMPLING OF WARRANTY CLAIMS SUBMITTED BY MBUSA DID NOT REVEAL ANY INDICATING A LOSS OF CONTROL DUE TO AN AIRMATIC SYSTEM FAILURE.THERE WAS ONE CRASH REPORTED BY MBUSA TO ODI BUT THE INFORMATION AVAILABLE INDICATED THAT IT RELATED TO SUSPENSION SYSTEMS AND IT WAS NOT POSSIBLE TO VERIFY THAT THE INCIDENT WAS RELATED TO AN AIRMATIC SYSTEM FAILURE. FURTHER USE OF AGENCY RESOURCES IN THIS MATTER DOES NOT APPEAR TO BE WARRANTED.THE AGENCY WILL CONTINUE TO MONITOR COMPLAINTS AND OTHER INFORMATION RELATING TO THE ALLEGED DEFECT IN THE SUBJECT VEHICLES AND WILL TAKE FURTHER ACTION IN THE FUTURE IF WARRANTED.THIS PRELIMINARY EVALUATION IS CLOSED.

I HAVE HAD TO REPLACE TWO CABLE HARNESSES FOR SEAT BELT IN BOTH FRONT SEAT. CONNECTORS ARE BEING REPLACED IN EVERY S CLASS DUE TO MORE THAN FREQUENT FAILURE. MECHANIC HAS INFORMED ME THAT THESE CONNECTORS BY NOT OPERATING WILL CAUSE SAFETY RESTRAINT AND AIRBAGS TO NOT DEPLOY IN ACCIDENT. CONSEQUENTLY HAD TO REPLACE RIGHT FRONT PASSENGER CHILD RESTRAINT SENSOR IN A 2004 S500 MERCEDES 4MATIC DUE TO FAILURE ALSO. BOTH ITEMS AS DESCRIBED ARE CONSTANTLY BEING REPLACED IN S-CLASS VEHICLES DUE TO FAILURE. LUCKILY I DID NOT HAVE AN ACCIDENT TO FIND OUT THE AIRBAG SYSTEM WOULD NOT ACTIVATE IN A CRASH. *TR

They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
