I purchased a certified used car from this dealers...

I purchased a certified used car from this dealership about 5 months ago(which took them a month and half to get my title), and have put approximately about 1300 miles on this vehicle. I recently brought my vehicle in for service, because there was a service light on the dash. While in for service, I had them look at some other concerns that I had with a vibration thru out the vehicle and a noise coming from my left front tire. Well that's when things became interesting, the service department told me that the vibration was coming from the motor mount, it was broken and the service light was on because of a rusted out front shock. I immediately called my salesman and discussed these things with him, he stated that I have a extended warranty, so just pay the deductible. I told him that I understand that I have purchased a extended warranty, but the repairs needed should have been noticed during the inspection to certify my vehicle. I was then told that it was out of his hands and I would have to talk to his manager. I called and left a message for Craig Muan the store manager, but still have not received a return call, I later called and talked with the used car manager(Rob), and discussed my situation; he stated that he would pay the deductible. Adam my service advisor was a great help, he fought hard for me and pushed these repairs back to the used car department, his help with these issues was greatly appreciated. I feel that customers are being cheated by this dealer, when they stamp the certified label on vehicles, because they really don't inspect these vehicles and the customer is left footing the bill in the end; false advertisement!
