For the past few weeks I've been smelling oil when turning on my car, at stops, etc. I took it into a dealer (it's a lease, under warranty.) $100 later, they tell me that my oil cap is cracked ($16 for the cap, $84 in fees/ labor) HOWEVER, because I had my oil changed at an "independent" place (i.e. NOT a dealer) I was told that my warranty did NOT cover this fee as the cap was placed on too tightly and caused a "hairline" crack in the cap. They returned the original cap to me, and there is absolutely no crack in it. 5 different people at my work have inspected it and none of us can find a crack. We are a group of mechanics/ hydraulics specialists and do repairs on machines regularly, so it's not like we work in retail or something. We are all quite qualified to inspect an oil cap. There is NO crack. I've seen that this is a problem for others with the Cruze on forums. I messaged an online live chat person with GM and they told me that I have to take the cap into a dealer again to have it inspected, and that forums are not approved GM support. Anyone else experience this? Does it seem right that this is not covered under warranty?
