I have a 2025 and on cold mornings my sync screen very faintly flashes Pro Power Onboard fault. But after I drive it will come on and all will work but the auto start stop button but that will work after I turn off and restart the truck. This only happens on mornings around 55 and below. First the dealer replaced my main battery but did not change than they said they flashed a module but know change. Than they said I had a code and need a new screen that they can't seem to get. this has been going on now for 2 months. When I brought up why did you change the battery than flash a module when we had codes the advisor just laughed and said we have to do this first. I asked about the 2 batteries under the rear passenger seat the advisor said not that. any info would be appreciated
