Had the brake issue for over 2 months now ever since it got cold. Doesn't happen always but my engine light has been on for weeks from the several brake failures. Also it is not just a single ignition cycle I have had to retry starting the truck over 3 or 4 times to clear it after waiting 20 mins.
2019 Trailboss LT, took it in early Jan had all the recalls fixed, alternator cable, catching fire issue and supposedly the brake fix flashing ECMB? Something like that. Anyway by mid Jan was -15 degrees and boom brakes go out before work. Then every other day or sometimes 3 days between. Now it has been week and a half since they failed but has been warmer. Check Engine light has been on for a month now, brand new truck engine light on it tickles the OCD part of my brain seeing it everyday. Will cross my fingers on this yet again time consuming process. Oh and can not get into dealer until March 10th .
