Loud Noise and Rattle in my R1S Cabin Before and After DCFC

Using a Small Generator and L1 Power + in Cabin Heat

A friend needed to support his son who would be running a 'very cold' marathon on Sunday while rucking a 30 pound pack. The outside temps will be around 15F-20F the whole time. The location of the race is nowhere close to any L2 chargers, but he's not worried about driving distance to or from the race - it is 50 miles away from his house. He says he will be sitting in his ruck with his laptop and watching his live track+Garmin inReach data for the duration of the race (about 4 hours). He thought about taking his Honda EB2800i gasoline powered generator, if he can use the level 1 EVSE attached to the generator and keep the truck running with full heat + power - without really consuming much of the truck's main battery? He feels it's super dorky to have a gas generator running while attached to a Rivian in the woods, just so he can stay warm, but don't know if it would work ok this way and 'preserve' the main battery so he doesn't need to worry about driving range when we wants to head home. He talked to me about it and I told him the simple answer is NO. I tested this theory the other night when I was plugged into a 5.9kW charger. To maintain the interior amenities (interior and exterior lights, radio, heater, seat heaters), it took almost all of the charge. I charged for 15 minutes, it delivered 1.6kW, and the truck consumed 1.4kW, delivering only 0.2kW to the truck battery. Told him he would be using a laptop at another 200ish watts. The little trickle charger charges at 1.4kW on a good day, 1.2kW is normal for me. You can slow the bleed, but you cant stop it. My advise to him was for him to charge it up to 100% at home, and roll the dice is what I would do.

On Sunday, I encountered a little trouble with my R1S and so far, I've been managing the issue as best as I can but I thought maybe it would be helpful if I did share my problems on here. Probably I could get a potential solution that might not require me to visit the SC.

I was on the road trip that day, heading to Vancouver and I believe precondition kicked in and there was loud noise and rattle in the cabin while driving.

I kept on driving but later on, decided to end the trip on navigation and it stopped, once I resume the trip on screen it started again. It happened again after reaching DCFC, and for a while, I guess it is for cooling the battery?

I contacted Rivian and they want video proof of it happen so that they can schedule the service center visit. I tried to repro the issue with putting in nearby DCFC, but it didn't work.

Anyone has any idea on how to repro it?
