2005 STS dies without warning - just happened on the hiway at 65mph. Accessory Active lights up on the dash. No power steering, no brakes. Have to stop, put in park and step on the brake to re start. I've put some fuel injector cleaner in it to see if that will help - any ideas?

 

If it were me I would take my car to the dealer or other facility for a proper repair.

 

I agree with you, I called the Cadillac dealership first, prior to posting, they said the first thing they would "try" was to use injector cleaner - just thought maybe someone here might have had the same issue in the past and would be able to help me diagnose the problem for the dealership. My experience with any repair person is if they can't "duplicate" the problem they can't diagnose it. Thanks for your suggestion.
