Loss of heat due to radiator leak. I found A192219310 out on the NHTSA site for Chevy TRAX used as Maven vehicles, but nothing about radiator issues on my GM account in the warranty section. .My car is a 2017 with 49251 miles. Light driving. The dealer was not aware of any issues with radiators. If I had known of the issues I would have had a pressure test sooner.
