Only your insurer can answer that question.
I am with you. In 60 years of driving GM cars the worst problem that I have had is a bad head gasket. Most have had zero problems. Including my current 2013 Acadia and 2013 Cadillac SRX.I hate to hear all the troubles folks have....
Im currently researching--- to order a 2023 Traverse....
All my GM cars have been trouble free..... as I stare out my window and look at the 2003 Trailblazer... still going.
Id be replacing my 2010 Traverse. Wife will continue to drive her 2013 Equinox- also with the 3.6.
