The vehicle was taken to the dealer and diagnosed that the failure was related to TSB - LI54.25-P-056472. The contact was informed that the Electronic Ignition Switch (EIS) needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but informed the contact that the warranty had expired and the TSB was not associated with the VIN.

THE VEHICLE IS PUTTING ITSELF INTO PARK WHEN YOU SLOW DOWN AND GET TO ABOUT 2-3 M.P.H. *TR

AT 80MPH, THE FRONT DRIVESHAFT U-JOINT FAILED, WHICH CAUSED A LOSS OF POWER AND A LOUD CLUNKING SOUND. VEHICLE WOULD NOT MOVE ON ITS OWN POWER. TEARDOWN SHOWED A COMPLETELY DESTROYED FRONT DRIVESHAFT U-JOINT, DAMAGE TO HEAT SHIELDING, DAMAGE TO OXYGEN SENSORS, DAMAGE TO THE CATALYTIC CONVERTER, ALONG WITH SUPERFICIAL DAMAGE TO THE BELLHOUSING AND MISSING BRACKETS. FAILURE IS SUSPECTED TO THE GEOMETRY OF THE FRONT DRIVESHAFT, WHICH CONNECTS AT AN ANGLE FROM THE TRANSFER CASE TO THE FRONT DIFFERENTIAL ON 4MATIC-EQUIPPED VEHICLES. THIS INTRODUCES ADDITIONAL STRESS TO THE U-JOINT, MAKING IT PRONE TO FAILURE.

FAULTY VALVE BODY ON A CAR WITH LESS THAN 50K MILES. CAR HAS BEEN MAINTAINED AS PER DEALER RECOMMENDATIONS. TRANSMISSION FLUID HAD BEEN RECENTLY CHANGED 4 MONTHS PRIOR. TRANSITION FAILED IN A LIFE THREATENING MANNER WHILE DRIVING ON A HIGHWAY. TOTAL LOSS OF CONTROL OF DRIVING CAPABILITIES. PROBLEM RESULTED IN A TOTAL OF $5585.29 IN A REBUILT TRANSMISSION AND NEW VALVE BODY. UPON RESEARCHING THIS SEEMS TO BE A REOCCURRING ISSUE WITH THE 722.9 TRANSMISSION. A RECALL SHOULD BE ISSUED.

REAR DIFFERENTIAL PINION BEARING. THE REAR DIFFERENTIAL IS MAKING A HOWLING AND LOUD NOISE. THE CAR ONLY HAD ABOUT 60K MILES AND THE BEARING FAILED. THIS IS A KNOWN ISSUE FOR THIS MODEL AND OTHER MERCEDES MODELS AS WELL. I GOT QUOTED AROUND $3000 TO FIX THIS. THIS SHOULD NOT BE AN ISSUE ON A $65,000 CAR AT THIS MANY MILES. MERCEDES BENZ NEEDS TO DO A RECALL ON THE RED DIFFERENTIAL SINCE THEY FAIL AT A VERY LOW MILEAGE.
