Crowley Kia

I purchased a 2010 GMC Yukon Denali in March of 2014. When I brought the SUV in for the first oil change I heard a knocking sound as when I drove it home while turning corners. I called the service department to complain of the noise, they looked at it and indicated that could not find nothing. Several times going forward after each oil change I complained about the noise and they indicated that they could not find anything wrong with the SUV. After going back and forth with the service department over several months I was told that even though the SUV was under warranty if they took apart the engine and found nothing I would be responsible to pay to have it put back together. I did not have the funds to pay such a fee at the time. Fast forward to another oil change I had done, they then gave me a list of repairs that needed to be done only to find out it was right after my warranty had expired. I feel that they set me up and was patching the problem so it will last so long until my warranty expired and then I would have to pay everything out of pocket get the problem fixed correctly or either they knew it would be drivable until the warranty expired. When asked about the extended warranty I had requested only then was I told by the car salesman when I asked for the monthly payments to be reduced when I bought the SUV that they cut my extended warranty. I ended up taking the SUV to have it fixed at another repair shop and it turns out that I had to replace the entire engine. This ended up costing me almost $7,000.00 out of pocket. I felt that this all could have been avoided if the service team would have been honest from the beginning as to what the problems were with the SUV. I could not just buy another SUV because I still have 4 years of payments left.
