rear coil spring snapped!

[kalaharix5]

Looked at the X5 the other day and seemed to be listing to the back drivers side. Couldn't see anything while on the ground so today jackup up and pulled the wheel and the rear coil spring is snapped. The bottom portion is gone and spring now hung up on suspension. It didn't drive unusual, but goes in Monday to be replaced.

Did a search and didn't see anyone else having the problem.

Only thing I can think is must have hit one of New England's wonderful pot holes and did the damage.

I have 74K miles on 2012 X5 3.5i with Route 66 extended warranty. Called them and was told it is covered under warranty...at least there is a bright side.
