So the other day my 04 xfire fell victim to the typical crankshaft sensor failing. I had the car taken into Westborn Chrysler (where i get all my work done) and they want to charge me the $90 diagnostic fee + my $100 deductible. My question is shouldn't this fee be covered under the warranty (sense the repair is a warranty case, I have the added care plus plan) or am i just being naive? What's the consensus, should i argue it or just pony up the dollars.
