The main 12v battery is charged by the 48v battery pack through a DC to DC converter. So an issue with the 48v battery pack could affect other things.Going back to look at this 2020 Limited. The sales man replied to me and admitted he was incorrect and I was correct, he was thinking of the etorque and this truck is NOT etorque. Yet, I don't think eTorque 48v lithium battery would effect all the electronics, but maybe. He said the battery was replaced and everything reset and now the tailgate, the backup camera, etc....is working.
If it is a good deal I don't care if he does not know the truck. I probably know more than him at this point. Wish me luck on my purchase!!
I do lots of research before buying a new truck, so I usually know more about them than whoever is trying to sell it to me. It would be difficult for a sales rep to know about every vehicle type they are selling, even if they stay at the same dealership for years. They're selling lots of different types of vehicles every day, and it would take a lot of extra effort on their part just to learn and remember everything about every vehicle their dealership sells. It might be a different story if a dealership has specialized sales staff for each vehicle type they sell. But I don't know of any dealerships in my ares that do this.
