 I've had my ML430 for about 1 year and have spent close to $5000 in repairs. I wish I researched more on this problematic SUV. I've soon realized I am not the only ML owner that feels that way. After 2 days of owning it, the transmission had issues. It wouldn't shift out of 2nd gear (common prob), Gas guage not working properly (common prob), then Catalytic converter started making noise($1500 to replace), Window/Door lock switch panel didn't work (common prob NOTE: there's a relatively easy DIY fix for the window. Now the it won't start because the factory immobilizer has died. Let alone the normal maintenance.
