I would love to see a photo of a recently delivered 2023 under belly. Are they cutting holes at the factory or is it a whole new belly cover that has been machine cut not hacked up by a dealership.
Actually what tears up the roads in snow country is the constant freeze and thaw that occurs here during winter. Water gets in the asphalt's cracks and then when refreezes expands and literally pops the asphalt causing bigger cracks and our famous pot holes.
Think about it for a moment. Winter time you are cold so you want heat in the vehicle so as to keep warm. You set your temperature at 72 degrees in your Maverick. There is only one way to produce that heat you are asking for. The ICE must run to heat up the circulating antifreeze mixture to pass...
Not normal. It reminds me of "run on" like when you shut off a lawn mower engine and it acts the same way. Usually caused when the fuel/air mixture in the cylinders ignites without a spark also known as dieselling.
