Software problems of the 2015 Chevrolet Spark

In the past I had a 2013 chevy Spark LS. But in 2017 an idiot who was texting and driving ran a stop sign, crossed through four lanes and t-boned my car injuring me and totaling my car. I am blessed to have survived. Until that day the only issue with my Spark was a failure of the "ignition / safety security chime". Prior to the accident it was addressed and fixed. Now I have a 2015 chevy Spark LS and have had a transmission failure reported, and fixed due to a national recall for 2013-2015's. However following the transmission replacement(matt bowers chevy-slidell,la )now I'm dealing with a total failure of the radio (black screen, no audio, no power) and no audio for the onstar buttons. As part of the transmission recall a list of all items "fixed" where given to me. A total software update was performed for radio, which now doesn't work. I reported this to the dealership who promptly blamed my radio/onstar failure on " the summer heat in louisiana ". I checked NHTSA for failures of the radio/onstar and found several documented cases of electrical failures of chevy Sparks, chevy sonics and other chevys. My radio (audio/screen) my onstar (audio) was working fine and did not signal any problems in the prediagnostic check prior to my total transmission replacement due to the transmission recall. It seems as though you can not trust that anyone will stand behind their products and work. I hope this information is helpful and I want to remind everyone to constantly check the NHTSA website for national recalls regularly. Several diagnostics were performed to find my transmission failure yet the site did not return a hit on my VIN number so at first the Chevrolet dealerships refused to perform services - due to my cars VIN not ( at first) being listed on the NHTSA site. Keep searching, print out information and bring in your mechanics automobiles diagnosis. Report the non-compliant dealerships if necessary. I hope that this is helpful to someone.
