The situations I’ve heard of personally have been trucks purchased from auction in Not Running condition. VIA still has a large inventory of things like the onboard charger and Battery cells if one is needed. Everything else on the truck like the generator and electric motor are built to last. If they are maintained and not dogged out, there is no doubt the trucks will get 250 - 300 maybe more until a battery cell needs replaced. Problem these trucks had honestly were their owners, they were fleet for some big companies. Several of the companies main request acted having trucks for a month or so was to add a no move feature when they were plugged in for charge. Reason for this had to do with employees consistently taking off in the truck with the charger still plugged in. This evidently was a repetitive issue?? On the display issue, I’m only aware of the small 3” screen that lets you know the status of the generator. How much kw and percentage of battery. There are no other displays on mine that were specific to this truck from via. Radio/GPS screen is regular Silverado oem. At the end of the day, you need to check to make sure all of your coolant systems are flowing like they are supposed to. Also, I don’t how they would handle this, but if I had purchased one that had done type of failure I would be trying to get them to honor their 8 year warranty if truck makes the date.
