Is a Cadillac dealership covered under repair pal?

RepairPal isn't an extended warranty, it's a web site for auto maintenance and repair advice and information. This is my understanding as a contributor answering Q&A here. Check your warranty contract to find out the terms and conditions of coverage and call the toll free number to ask specific questions. If a covered component, it's possible you may need to see a specialist like at your local dealership for repairs.
