NHTSA Complaint #11433566 — 2022 WINNEBAGO REVEL

This is a Sprinter van finished by Winnebago into the 2022 Revel 44E SN 15219109. We have 1,500 miles on van and took delivery three weeks ago. Friday 9/17/21 While driving the van at highway speed in Massachusetts on I495, we detected an acrid burning smell and the van quickly filled with smoke. We were able to pull over, shut down the vehicle and open the doors. We found in the rear compartment where the lithium battery system is located a damaged/melted connection. It appears the bolt/nut connecting the wire from the alternator charging system wasn't tightened creating heat which burned away the rubber boot covering the terminal. In looking at other connections in this area, all other nuts are marked with a paint pen to show they were verified for tightness. The connection that was damaged and melted away it's rubber cover was not marked. There were no warnings/alarms to state an issue was going to/was occurring. The vehicle is <3 weeks old from pickup at factory delivery center We feel this could've resulted in a less experienced driver potentially going into panic mode and potentially causing an accident. In addition, this fire/arching occurred next to (2) lithium batteries which could've created a fire/explosion. I searched for this issue and found other owners on the FaceBook Revel owners forum have had similar issues with their units - therefore I'm reporting this to prevent other owners/potential owners from having this defect.
