Sports City Toyota Do not honor Warranty work Mesquite Texas

My wife and I purchased a 2009 Scion TC. Basically a Toyota corolla under the Hood.  At first we where very happy. We had FREE oil changes for life.  So we took full advantage of this.  Every time it was time to change the oil , we where there getting it changed.  We only missed ONE due to the service department under construction. We purchased the extended warranty 100k miles or 4 years I believe. At about 96k miles the motor throws a rod.  Mind you , we NEVER missed an oil change. When they where closed I changed it myself.  Well , I take it in to get the warranty work done. After a month of fighting tooth and nail with Sports City and Onyx , I finally got the engine replaced By warranty.  Webbing a trusting person , I was told the warranty on the "NEW" motor was one year unlimited miles.  Word of advice.  NEVER just take someone's word. Higher it in writing.  Well after driving about 7 thousand miles and 2 oil changes later , the motor starts knocking   I immediately pulled over and had the car toward to Sports City. I was not going to cause any further damage if any had been done.  I go to talk to the service advisor and we discovered it was about to throw a rod again. Not even 10 thousand miles after the last motor swap. Ok I was confident that warranty was going to cover the motor swap. I mean they have documented proof we never missed an oil change. Now, because SOME CHEAP BUTT at Sports City wanted to save money , apparently the last motor swap, they replaced with a motor that had 60 k miles already and was also told that there was no 1 year warranty like I was told.  Instead it was an EOT warranty ( End of Term ). Basically end of original extended warranty.  Why earth would you warranty a motor for only 6 thousand miles??  Ok back on topic. After a lot of sleep less nights and fighting back and forth , my wife and I where told we are just SOL. Nothing they can Do.  They aren't replacing under warranty.  So we traded it in on a New Ford Edge. We will NEVER EVER buy another Toyota again.  I hope I made sense. A lot of info to fit in there.  Oh and coincidentally the lady that told us about the year warranty on the supposed NEW motor no longer works there. So PLEASE PLEASE DO NOT BUY from Sports City Toyota. I have list so much sleep and hair because of this very stressing issue.  Thanks y'all.  Have a good one
