Where do I start?
Maybe by stating what hasn't gone wrong, it still has 4 wheels, but the brake pads needed changing at 18,000 miles and it's not as though we drive it hard.
The stereo still works, but the reception is poor on AM.
What has gone wrong?
You name it, it's happened to this 'quality' vehicle. Numerous electrical problems all well documented by previous model year owners.
On average a visit to the shop every couple of months to have something fixed which can't wait - windows stuck down, machine gun door locks, check engine light etc etc
I would have thought that MB would have gotten it's component suppliers in line by now and producing quality parts.
They must be cutting costs on QA I guess.
As for MB USA comments on this lemon - they really don't care about their 'customers'.
MB does not standby their problem ML's.
I have driven 50000 miles on a 1998 ML320 with only one problem: A key code failure on my ignition key. For that, the dealer picked up my car on a truck and paid for our motel and rental car. Fixed the problem the next day and we are happy. Since then I have driven 18000 miles on a 2002 ML500. The only problem with was the battery went dead after I left my lights on all night in my garage. The dealer came out and replaced the battery free of charge. Going 10000 miles before free service is also a bonus.
