It depends on the type of warranty. If the car is under the original waranty, it will be covered provided there wasn't a 3rd party to have caused or attempted to cure the problem. If the car has a Starmark warranty, it is just about the same as the original warranty. If the warranty is the extended factory warranty you'll get somewhat the same coverage as with the original warranty, depending on which extended warranty (there are 2 to my knowledge). If the warranty is from somewhere else, then it would depend on the inclusions of the warranty.
All this said, generally a "bumper to bumper" warranty covers everything between those 2 points
Hope this helps.
