Suggestion
If you have some time to read XM Radio & Brake Squeal Thank You! you'll see my complaint (over & over ad nauseam) regarding having to bring the XLR in for every single problem, three times or more.
Some dealers are better than others, of course, but it sounds like many in this forum want to go to "their" dealers who are nice, respectful, and clueless about XLR's, because they are so new, complex, and the mechanic actually has to be able to read English to research EVERY problem with servicing this car (maybe they speak English in TX or CA, but not in NY!
My recommendation (its been working for me since discovering this forum) is to print out all of the answers from the forum, and bring it to the service manager on the 1st visit.
This makes it MUCH harder for them to B.S. you and get rid of you, because your showing them proof from 5 or 10 other owners, that the car ISN'T SUPPOSED TO DO THIS!
Mine was the brake squeal issue (muched discussed here). Without the forum, I was told "they squeal just like Porche brakes, get used to it". With the forum I got a new set of rotors and brake pads all under warranty--thanks to the forum I even had the service bulletin for the dealer to read--they thanked me for it :yesnod .
I've said it b4, this forum rocks!!!
