DRIVING ON TAPPAN ZEE BRIDGE NEAR NYC AND SLOWED DOWN TO APPROX 15 MPH FOR TOLL BOOTH AND TRIED TO ACCELERATE OUT OF THE TOLLS. THE VEHICLE WAS VERY LOUD AND WOULD NOT ACCELERATE. IT ALMOST SOUNDED LIKE I WAS DRIVING OVER RUMBLE STRIPS AND I ALMOST CRASHED TRYING TO PULL OVER AS THE EZ-PASS IS ALL THE WAY ON THE LEFT SIDE OF THE FREEWAY. AFTER I GOT OUT THE FRONT PASSENGER ROTOR/CALIPER WAS ALMOST GLOWING AND ERUPTING WITH SMOKE, THE 3 OTHER BRAKES LOOKED FINE. THE SMOKE DID NOT STOP FOR AT LEAST 10-15 MINUTES AND IT SMELLED ABSOLUTELY TERRIBLE EVEN STANDING 15 FEET AWAY FROM THE VEHICLE. THE VEHICLE HAD TO BE FLAT-BEDDED TO THE DEALERSHIP AND THEY WHERE NOT ABLE TO DIAGNOSE THE ISSUE, THEY SAID IT SEEMED LIKE AN ELECTRICAL PROBLEM. AFTER BRINGING IT TO ANOTHER SHOP THEY SAID IT WAS A FAULTY YAW RATE SENSOR. *TR

MY 1999 MERCEDES ML320 STALLED IN TRAFFIC ON THE INTERSTATE. I HAD IT TOWED TO THE DEALER WHO REPLACED THE CRANKSHAFT POSITION SENSOR WHICH SHOWED A MARGINAL PROBLEM. WE PICKED UP THE CAR AND BROUGHT TO THE ATTENTION OF THE MANAGER THAT THE "CHECK ENGINE" WAS ILLUMINATED. HE SAID THAT WAS BECAUSE THERE WERE SOME PLUGS MISFIRING, BUT THAT WOULD HAVE NO BEARING ON THE CAR STALLING. THE NEXT DAY, THE CAR STALLED IN TRAFFIC AND WAS AGAIN TOWED TO THE DEALER. THEY CAN FIND NOTHING WRONG WITH THE CAR AND SAY IT RUNS LIKE A TOP. WE REFUSED TO TAKE THE CAR UNTIL THE PROBLEM WAS RESOLVED SO IT WAS DECIDED THAT A TECHNICIAN WOULD DRIVE THE CAR UNTIL IT STALLED AGAIN. THAT HAS BEEN GOING ON FOR ONE WEEK WITH NO STALLING. WE ARE AT A LOSS AS TO HOW TO PROCEDE WITH THIS ISSUE. WE DO NOT FEEL IT IS SAFE TO DRIVE THE CAR BECAUSE WE FEAR IT WILL STOP AGAIN IN TRAFFIC AND CAUSE AN ACCIDENT AND/OR DEATHS. *TR

THE CAR WAS NOT IN DRIVABLE CONDITION AND I TOWED IT TO MY NEAREST SERVICE STATION. AFTER DIAGNOSIS, POWER STEERING HOSE AND CLAMP WERE REPLACED AND THE CAR IS RUNNING GOOD NOW. LATER I FOUND THAT THIS IS A KNOWN ISSUE IN 1999 MERCEDES ML 320 AND FOUND RECALL CAMPAIGN DETAILS OF THIS ISSUE IN NHTSA WEBSITE. BUT WHEN I CALLED MERCEDES USA TO GET A REIMBURSEMENT FOR THE REPAIR COST, THEY ARE REFUSING TO GIVE REIMBURSEMENT FOR A STRANGE REASON. I AM STILL FOLLOWING THIS ISSUE WITH THEM. *TR

I WAS DRIVING ACROSS THE VERRAZANO NARROWS BRIDGE FROM BROOKLYN TO STATEN ISLAND. JUST PAST THE TOLLS, MY HARMONIC BALANCER FAILED, CAUSING THE SERPENTINE BELT TO SIZES AND STOPPING THE ENGINE. CONSEQUENTLY, I LOST STEERING AND BRAKING BECAME VERY HARD. I WAS MORE-OR-LESS POINTING TO AN SHOULDER/EMBANKMENT BETWEEN THE MAIN HIGHWAY AND THE EXIT IMMEDIATELY PAST THE TOLLS. I COASTED TO THAT EMBANKMENT AND USED ITS SLOPE IN PART TO HELP STOP THE VEHICLE. I WAS SUBSEQUENTLY TOWED TO RAY CATENA MERCEDES IN EDISON, NJ. I WAS INFORMED BY THE SERVICE ADVISOR THERE (MR. HESSERT) THAT THIS FAILURE WAS PART OF A "CAMPAIGN" AND THAT IT WOULD BE REPAIRED ALONG WITH ANY COLLATERAL DAMAGE "FOR FREE" BY MERCEDES. I ASKED "SINCE WHEN" WAS THIS CAMPAIGN IN EFFECT, THEY STATED SINCE APRIL OF 2005. I ASKED WHY I WAS NOT NOTIFIED OF THIS AS I AM THE REGISTERED OWNER. WE BOTH TOGETHER THEN CALLED MERCEDES CUSTOMER SERVICE AND WERE INFORMED THAT THERE WAS NO 'NOTICE' AND THAT THIS WAS NOT A FORMAL RECALL. HAD THIS FAILURE HAPPENED 40 MINUTES EARLIER WHILE I WAS ON THE LONG ISLAND EXPRESSWAY, OR 10 MINUTES LATER WHEN I WOULD HAVE BEEN ON THE GOETHALS BRIDGE, I WOULD HAVE BEEN AT THE VERY LEAST SEVERELY INJURED IF NOT DEAD NOT TO MENTION ANY OTHER VEHICLES AND INDIVIDUALS WHO WOULD INEVITABLY BEEN INVOLVED. I AM TOLD THAT THE _DEFECTIVE_ HARMONIC BALANCER WILL BE REPLACED ALONG WITH THE SERPENTINE BELT AND THE "UPPER OIL PAN" AS THAT PART WAS DAMAGED DURING THE FAILURE. I WILL REQUEST THAT THESE PARTS BE RETAINED.

Official recalls
4Mar 31, 2011
MERCEDES-BENZ IS RECALLING CERTAIN MODEL YEAR 1999-2002 M-CLASS AND MODEL YEAR 2000-2003 M-CLASS AMG VEHICLES. THE CRUISE CONTROL SYSTEM IN THE AFFECTED VEHICLES ALLOWS THE DRIVER TO DISENGAGE THE SYSTEM IN A NUMBER OF WAYS, INCLUDING TAPPING THE BRAKE PEDAL, USING THE CRUISE CONTROL STALK, OR BRAKING THE VEHICLE ENOUGH TO REACH A CERTAIN RATE OF DECELERATION. MERCEDES-BENZ HAS DETERMINED THAT UNDER CERTAIN CIRCUMSTANCES USE OF THE BRAKE PEDAL MAY NOT AUTOMATICALLY DISENGAGE CRUISE CONTROL AS EXPECTED BY THE DRIVER, ALTHOUGH THE OTHER MEANS OF DEACTIVATING CRUISE CONTROL REMAIN FULLY OPERATIVE. SPECIFICALLY, WHERE THE DRIVER PUMPS THE BRAKES RATHER THAN APPLYING CONSISTENT PEDAL FORCE, THE LEVEL OF FORCE REQUIRED MAY BE UNUSUALLY HIGH.
Consequence & remedy
Consequence: DIFFICULTY OR DELAY IN DISENGAGING CRUISE CONTROL CAN INCREASE THE RISK OF A CRASH.
Remedy: DEALERS WILL REPAIR THE VEHICLES FREE OF CHARGE. THE SAFETY RECALL BEGAN DURING OCTOBER 2011. OWNERS MAY CONTACT MERCEDES-BENZ AT 1-800-367-6372.
Sep 17, 2008
MERCEDES-BENZ IS RECALLING 125,228 MY 1998-2004 M-CLASS VEHICLES. THE HOSE CLAMP USED TO SECURE THE POWER STEERING FLUID COOLING HOSE TO THE POWER STEERING FLUID COOLER MAY NOT PROVIDE SUFFICIENT CLAMPING FORCE FOR THIS CONNECTION.
Consequence & remedy
Consequence: THE LOSS OF POWER STEERING FLUID MAY RESULT IN DIMINISHED POWER STEERING OVER TIME AND ULTIMATELY CAN DAMAGE THE POWER STEERING PUMP. THIS COULD RESULT IN A LOSS OF CONTROL AND A CRASH WITHOUT WARNING.
Remedy: AN EARLIER RECALL REPAIR PERFORMED ON THESE VEHICLES MAY NOT BE SUFFICIENT TO PREVENT A FUTURE LEAKAGE OR FAILURE OF THE POWER STEERING HOSE CONNECTION (PLEASE SEE 03V121). SINCE IT IS NOT POSSIBLE THROUGH INSPECTION TO IDENTIFY SPECIFIC VEHICLES THAT MAY NOT HAVE BEEN PROPERLY REPAIRED, ALL VEHICLES REPAIRED PRIOR TO NOVEMBER 15, 2003, WILL BE REPAIRED AGAIN. THE RECALL IS EXPECTED TO BEGIN DURING NOVEMBER 2008. OWNERS MAY CONTACT MERCEDES-BENZ AT 1-800-367-6372.
Mar 27, 2003
ON CERTAIN PASSENGER VEHICLES, THE HOSE CLAMP USED TO SECURE THE POWER STEERING FLUID COOLING HOSE TO THE POWER STEERING FLUID COOLER MAY NOT PROVIDE SUFFICIENT CLAMPING FORCE FOR THIS CONNECTION.
Consequence & remedy
Consequence: THE LOSS OF POWER STEERING FLUID MAY RESULT IN DIMINISHED POWER STEERING OVER TIME AND ULTIMATELY CAN DAMAGE THE POWER STEERING PUMP.
Remedy: DEALERS WILL INSTALL A NEW HOSE CLAMP ON THE POWER STEERING HOSE TO THE POWER STEERING COOLER. DURING CLAMP REPLACEMENT, THE POWER STEERING COOLING HOSE WILL BE INSPECTED AND REPLACED AS NECESSARY. OWNER NOTIFICATION BEGAN JUNE 16, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT MERCEDES-BENZ AT 1-800-367-6372.

VEHICLE DESCRIPTION: SPORT UTILITY VEHICLES. THE LATCHING MECHANISM ON THE SEAT BELT ASSEMBLY WAS NOT ASSEMBLED CORRECTLY. IF THE PLASTIC COVER IS LOOSE DURING THE ENGAGEMENT OF THE BUCKLE TONGUE TO THE LATCH MECHANISM, THE BUCKLE COULD UNLATCH.
Consequence & remedy
Consequence: IN THE EVENT OF A CRASH, THE SEAT OCCUPANT MAY NOT BE PROPERLY RESTRAINED, INCREASING THE RISK OF PERSONAL INJURY.
Remedy: DEALERS WILL INSPECT THE SEAT BELT BUCKLES. IF EITHER THE DRIVER OR FRONT PASSENGER SEAT BELT BUCKLE IS FOUND TO BE DEFECTIVE, IT WILL BE REPLACED.

CONTINUED OPERATION WITH THE BRAKE WARNING LAMP ILLUMINATED WOULD ULTIMATELY DRAIN THE RESERVOIR FOR THE AFFECTED CIRCUIT, RESULTING IN LOSS OF THE CIRCUIT AND AN APPROXIMATELY 80% INCREASE IN STOPPING DISTANCES.
