Just bought a new 2024 Chevy High Country 3500 HD Dually Duramax and with less than 300 miles it has just shut off while driving!...(showing reduced power..check SCM...check this, check that...etc...after rolling over to the curb and trying to re-start...(it didn't, just cranked non stop until I hit the start button to stop it)...frustrated, I dis-connected the main battery and waited 30 seconds and re-connected it...voila!...it miraculously went back to normal and started....dealership is confounded...can't find anything wrong...has ordered a new ECM, however, I don't think that was the problem...Anyone else have a similar event happen?...It has now happened twice!...after clearing false codes, it goes right back to normal showing nothing wrong...vehicle runs and acts perfect until it mysteriously shuts down again...Beyond frustrated!......
\\\\\\\ UPDATE ////// After installing the new ECM update the truck is fixed.
