Rivian’s battery sits low in the vehicle as part of what is called the skateboard platform, and it uses a steel cover with hundreds of spot welds holding it together.
Any structural repair near that area has to be handled by someone trained specifically in high-voltage safety, not someone who is cautiously hoping for the best.
Heritage Collision technicians go through that training before they ever touch a Rivian on the lift.
If your Rivian was in a collision that affected the frame, the bed, or anything near the battery enclosure, this is exactly the kind of repair that needs a certified body shop, not a general one.
