TAKATA RECALL...I HAVE HAD A RECALL FOR A VERY LONG TIME ON MY AIR BAGS AND HAVE NEVER BEEN CONTACTED BY MERCEDES AGAIN AFTER THE INITIAL RECALL.

TAKATA RECALL. HAVE CONTACTED DEALERSHIP NUMEROUS TIMES IN THE LAST YEAR AND HALF REQUESTING WHEN IT WOULD BE FIXED AND ARE TOLD IT IS STILL PENDING. I WOULD EXPECT FASTER SERVICE ON THIS POTENTIAL DANGER WITH THE DEFECTIVE DRIVER SIDE AIRBAG.
DRIVING ON A FEEDER ROAD IN LIGHT TRAFFIC AT ABOUT 55 MPH, WE WERE STARTLED BY AN ENORMOUS LOUD EXPLOSIVE SOUND ON OUR SUNROOF OF THE ML 550, LIKE A BOMB SOUND.

MERCEDES DEALERSHIP ESTIMATED $2,777.00 TO REPLACE GLASS, DROP HEADLINER AND REMOVE BROKEN GLASS SHARDS/PIECE. MB DID NOT OFFER ANY EXPLANATION AS TO DEFECTIVE SUNROOF GLASS.
