Forgive me if this has been asked before but it just happened to me. I was driving just a short distance and suddenly by batt. light came on the dash and I lost power steering.
When I looked under the hood I had small amounts of oil coming out of the oil filter cap area, and the belt was completely thrown off.
Car still drove, it was fine , just no power steering and the batt light stays on.
What is my problem, why,and where can i find a diagram of the serpentine belt, to re-install?
I was told it could be an oil filter seal failure and when oil leaks onto the belt, it will throw it off, a new oil filter and seals fixes it. Is this true?
Has this happened to anyone else? My car is an 2007, sunday only driver, 11,000 miles.

Thanks in advance for any help,

Mark
