2007 MERCEDES BENZ ML320 Fuelpropulsion System Problems

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.
