When I brought the vehicle back the first time, they "apparently" did check it and they said that the check engine light had nothing to do with the recall they performed. Having my mech go over it was to review that claim and see if such was the case or if they messed up something. As of right now, there is no opportunity as you claim to "get them" on this. I have nothing concrete to back it up. All that will happen is that the Stealership will continue to charge me for their time assuming I want them to have a look at this again. This is because they, in their statement, have already looked into it the first time and found nothing.
