If you notice water around a sunroof after rain, capture the exact conditions instead of relying on “it happens sometimes.” Record which corner or headliner area gets wet and whether the car was parked on a slope. Save the date, mileage, and any warning message.
Repeatable notes help a technician reproduce the concern and distinguish a one-off event from a pattern. Check visible drain outlets without forcing wire or compressed air into them.
Quick educational note
For information, not a diagnosis or repair instruction. Vehicle-specific checks are still required. Consult the manufacturer's guidance and a qualified technician.
