Water inside the boot (and on the Model Y also in the rear or in the passenger footwell) through poorly sealed body areas

Engine / equipment

Body and boot lid sealing: Tesla Model 3 and Model Y

Period mentioned

2017–2023

Symptoms

Water or damp in the boot; on the Model Y, AUTO BILD also mentions water at the rear seats and in the passenger footwell.

Possible cause described

Tesla acknowledges in bulletin SB-23-10-002 (April 2023) that on some Fremont-built Model 3 cars (model years 2017–2023) water gets into the boot through the boot lid; the fix is to reseal it, including around the inner rear lamps. AUTO BILD (2026 TÜV report) mentions poorly sealed body areas on the Model Y through which water gets into the boot, the rear seats and the passenger footwell.

Check for the garage

Look under the boot floor and the mats after rain or a car wash. If there is water, ask Tesla service to find where it gets in and seal it.
