The model(s) and model year(s) listed are a general approximation of the affected VIN list. Refer to the VIN/Bulletin Tracker or Customer/Vehicle profile to determine
applicability of this bulletin for a particular vehicle.

Repair Bulletin: This repair bulletin provides instructions on addressing a noted condition or possible customer concern regarding
the operation of Tesla vehicles. These instructions should only be performed by trained professionals.

This Service Document supersedes SB-23-10-003 R1, dated 17-Apr-23. This new revision, R2, adds an alternative
part number for the sealant to be used in the EMEA region. Each content change is marked by a vertical line in the left
margin. Discard the previous version and replace it with this one.

Condition
On some Model Y vehicles, water may have leaked inside the rear trunk area through the liftgate assembly.

Correction
Inspect inside the trunk area for signs of water leaks that came through the liftgate assembly. If this symptom is
present, reseal the liftgate assembly.
Tip: Click here to watch a video that shows an overview of this procedure. Although the video shows this
procedure being performed on a Model 3, Model Y is similar.

NOTE: This procedure addresses water ingress through the liftgate assembly and not due to water entering the
vehicle while the liftgate was opened in the rain.

NOTE: Although the figures in this procedure highlight one side of the liftgate assembly, this procedure must be
performed on both sides (LH and RH) of the liftgate assembly.

Procedure
1. Remove the liftgate upper trim (refer to Service Manual procedure 15111002).
2. Remove the liftgate lower trim (refer to Service Manual procedure 15111302).
3. Remove the LH and RH rear fog/reverse lights (refer to Service Manual procedure 17402701).
4. Remove and discard the factory foams (x2) (Figures 1–4) located under the LH and RH lamp can panels inside
the liftgate assembly.
CAUTION: Wear appropriate eye safety glasses and protective earplugs as Personal Protection Equipment
(PPE).

5. Prepare the caulking gun (1939249-00-A) with the 5510 white sealant (1939248-00-A) (Figure 5). Cut an
approximately 4 mm wide opening on the sealant dispensing tube (Figure 6) using a retractable blade knife.

6. Apply the sealant on top of the LH and RH lamp can panels located inside the liftgate assembly (Figures 7–10),
and then spread the sealant bead with your finger (Figures 11 and 12) while wearing a nitrile glove. Apply several
sealant beads as needed.
CAUTION: Use nitrile gloves as PPE for the remainder of this procedure.
NOTE: Make sure to apply the sealant between the panels (Figure 12).

7. Apply the sealant on the sides and the back side of the LH and RH lamp can panels located inside the liftgate
assembly (Figures 13–16). Spread the sealant bead with your finger while wearing a nitrile glove. Apply several
sealant beads as needed.
NOTE: Use the dauber (1939250-00-A) in tight spaces (Figure 15).
NOTE: Make sure to apply the sealant between the panels (Figure 16).

(Figures 16–20). Apply several sealant beads as needed.
NOTE: Use the dauber in tight spaces (Figure 15).
NOTE: Make sure to apply the sealant between the panels (Figure 20).

10. Use a plastic trim tool to remove any previously applied non-factory sealants in the highlighted areas, if present
(Figures 26–29).
CAUTION: Do NOT remove factory sealant. To differentiate between factory sealant and non-factory sealant,
factory sealant is painted over and is harder to remove, and non-factory sealant is usually clear and easier to
remove than factory sealant.
NOTE: Use adhesive remover, as needed.

11. Clean the liftgate assembly seams areas with Isopropyl Alcohol (IPA) wipes (Figures 21 and 22).
12. Apply sealant ONLY on the openings and pin holes found during the inspection (Figures 30 and 31).
CAUTION: Do NOT apply sealant to the entire liftgate assembly.

13. Remove excess sealant with a clean, dry microfiber cloth. Allow 1 hour for the sealant to fully cure
(Figures 32–35).
CAUTION: Do not use chemicals to remove excess sealant.
NOTE: The sealant must be allowed to cure for 1 hour because touch-up paint will be applied onto it later in
this procedure.

14. Apply sealant on the upper and lower panel mating surfaces for the LH and RH sides (Figures 36–39). Allow
1 hour for the sealant to fully cure.
NOTE: Apply sealant with your finger while wearing a nitrile glove, and then work sealant onto the factory
sealant.
NOTE: Make sure to apply the sealant between the panel mating surfaces (Figure 39).
NOTE: The sealant must be allowed to cure for 1 hour because touch-up paint will be applied onto it later in
this procedure.
