trane inc. ingersol rand trane XV20i units do not work! Nationwide

Had a trane XV20i and tam8 installed july 2014 .It took over two weeks to make it work and then only fair. In the first year the compressor stopped and burned wires, also the evaporator coil leaked and was replaced.Next summer stopped again took over a week this time more parts worked fair again.2016 guess what POS stopped more parts,installer said no longer will sell or work on train! Now summer of 2017 earley june stopped I called 4 companies that sell and repair trane none will touch the Xy20i !!! Found a former trane co willing to fix it,three weeks more parts plus them on the phone to trane tech support DOES NOT WORK!  The repair co. wantes trane tech to come here to fix it we will see.  Three years in only two parts left to replace condensor coil and reversing valve. Every year called trane complant line ,responce" I see you have caller before will look in to it " .Now want me to send all bills to see what they will do. I will never trust trane again.  Trane needs to be sued
