My 2007 MB ML320 CDI has problem with water entering where spare tire located,after rain or when i use car wash.It builds inside so much water that module for for fuel pump stopped working,all wires were corroded,I paid for repairs from my pocket because MB dealership refused to fix my vehicle even they new MB ML/GL models have issue with water entering spare tire area.Now I find out they have recall with over323,000 ML/GL models.Recall number22v-955.I would like to file this complaint because dealership refuses to cover my previous repairs.Water still entering trunk area,and I have to constantly drain and vacuum trunk area.I hope you will have another recall or add older MB ML/GL to recent recall list.Thanks.

YEARS AGO, WHILE DRIVING THROUGH NEW MEXICO, MY DASH AND COMMAND CENTER FLASHED OFF AND REBOOTED. IT WAS A LITTLE CONCERNING BECAUSE WE WERE USING THE GPS EXCLUSIVELY FOR OUR DIRECTIONS. THERE WAS ALSO A TRANSMISSION WARNING LIGHT THAT CAME ON WARNING US TO GET TO THE NEAREST DEALER, WITHOUT SHIFTING GEARS. THIS HAPPENED PERHAPS 10-15 TIMES UNTIL I WAS ABLE TO DETOUR TO THE MB DEALER IN ALBUQUERQUE - ABSOLUTELY WONDERFUL PEOPLE. THEY TOLD ME THAT IT WOULD SOUND STRANGE BUT THE PROBLEM WAS CAUSED BY A FAULTY GLOW PLUG SENSOR OR MODULE - WHICH THEY DIDN'T HAVE IN STOCK. SINCE OUR DESTINATION WAS L.A., THEY CALLED AHEAD TO MB OF BEVERLY HILLS (BH), (ALSO WONDERFUL PEOPLE) TO CHECK IF THEY HAD ONE. THEY (MB OF BH) COULDN'T FIND ANY OTHER TROUBLE CODES EXCEPT A FEW POWER SPIKES SO THEY REPLACED THE ALTERNATOR, UNDER WARRANTY. THEY EVEN RUSHED IT DUE TO A FAMILY EMERGENCY BACK HOME. IT HAPPENED ON THE WAY BACK SEVERAL TIMES, THEN DIDN'T HAPPEN AGAIN UNTIL I DROVE TO COLORADO IN 2013. IT HAPPENED REPEATEDLY WHILE THERE. I CALLED THE MB DEALER IN DENVER WHO WAS SUPPOSED TO HAVE THE SERVICE DEPARTMENT CALL ME BACK - THEY NEVER DID. I WONDER IF IT HAS SOMETHING TO DO WITH A CHANGE IN ALTITUDE OR LOWER HUMIDITY (ELECTROSTATIC DISCHARGES)- PERHAPS EXTENDED DRIVING AS I DROVE 1,200 + MILES TO CO IN 20 HOURS STOPPING ONLY TWICE FOR FUEL AND ONCE FOR A HOTEL. ANY IDEAS FOLKS? *JS
