 Rear window fell into the door!!!!  The 
plastic carriage had  broken.  Service 
advisor told me, since the cost of this 
item is handled by the outsourced 
manufacturer of the part and not 
Mercedes, Mercedes does not care and 
has not and will not address this 
issue.  Customer headache is not 
sufficient reason to address this 
problem!!??
Check Engine Electronics light comes on 
for no apparent reason...call the MB 
service advisor, am told not to drive 
the car but that I cannot get a loaner 
car  for 2 weeks....he was very helpful 
in suggesting that I rent a car in the 
meantime!!!!!!!says they have 150 
loaner cars, all are out
