BMW X7 2026 water condensation tail light

I just do car wash by myself and see water condensation in tail light.

Is that normal?

I’ve seen this issue before and would recommend having it inspected sooner rather than later. In some cases, it can be something minor like a compromised seal allowing moisture in. However, if left unresolved, condensation can potentially affect the internal electronics or wiring, which could turn a simple taillight issue into a more expensive repair.
