This is a common issue with sea transport. If the vehicle is parked at a humid dock, the EPB can easily rust to the brake disc. In addition to testing its release before shipping, we try to ask dock workers to secure the wheels with chocks instead of fully engaging the electronic parking brake.

We maintain an absolute skeptical attitude. In addition to regular visual inspections, we focus on checking for sediment accumulation around the sunroof drainage channels and look for water stains under the A-pillar trim and front floor mats. This is the only effective physical evidence to determine if the sunroof drainage holes are blocked, leading to hidden leaks.

The lifespan of rubber sealing strips for frameless doors is usually only 4-5 years. We carefully press the sealing strip at the edge of the roof to check for loss of elasticity and use a high-pressure water gun to wash the seams of the windows to check for direct water leakage due to aging.
