NHTSA complaint #11660662, filed 2025-05“Both front doors on my 2021 Nautilus Reserve have structural stress cracks in the sheet metal surrounding the check-arm bracket, along the edge of the recessed mount and under the weatherstrip. I first noticed cracking and popping when opening and closing the doors on 8/1/2026 at about 84,000 miles. No collision; normal use. The bracket mounts to the inner door panel with no reinforcement. The panel visibly flexes every time the door opens and checks, and that flexing has fatigued and cracked the metal. The cracks are growing. This is a safety issue. …”
