Engine Knocking Noise Problems of Hyundai XG350

I'm a single mom and have no family here in CT. To help me or guide me in this sort of thing. My car started making a knocking noise under the hood. I didn't know what it was so I took it to my mechanic. It took a couple of days before some one there could look at it. He told me it was an engine knock and said I should take it back to the dealership to get it fixed. By the time I contacted key in milford CT, my car was out of warranty by eight days. And that's all they kept telling me. Keep in mind, I brought the car to my mechanic the day before the warranty expired. Key charged me 105. 00 to determine it was in fact an engine knock,after I told them my mechanic told me what it was. Key had no loaner car to lend me while my car was there. Later I found out there was a waiting list for loaners. No one offered to put me on the list and no one tried helping me with a rental. I paid for a rental the entire week they were playing games with me wanting to charge me 10,360. 00 for a new engine and wanted to charge me an extra 380. 00 to find out what exactly went wrong with the engine, before they decide to replace it. No one is giving me any guarantee that the warranty will be granted. I bought my car there 9/15/06 had my car for three yrs,it's a 2004 Xg350 with 46000 miles on it. It sounds to me like the engine had a defect. Everyone else I spoke with said the same thing. I contacted the manufacture company and no one was trying to help me. I took my car out of key and brought it back to my mechanic to have the engine replaced. I am looking for some sort of reimbursement from key for all these games they want to put me through, trying to rip me off. My car was in fact in the shop the day before the warranty ran out, March 14, 2009. I have all of my maintenance receipts and records. Key checked all of the cars fluids and everything was clean. I don't think engines go bad over night. Can some one help me?.
