Readjust Hood Latch

Condition

On certain 2014 to 2021 Model S vehicles, the secondary hood latch may not latch to the frunk striker as designed.

 

Correction

Inspect the vehicle for the symptom related to the condition. If the symptom is present, readjust the hood latch to
correct alignment specifications.

 

Procedure

  1. Open the LH front door and lower the LH front window.
  2. Press the brake pedal to turn on the drive rails.
  3. Open the hood through the touchscreen (Figure 1).

 NOTE: Do not close the hood until instructed to do so.

 

  1. With the vehicle stationary, firmly press on the brake pedal, shift the vehicle into Drive, and then shift back to Park.

 NOTE: The warning messages โ€œFront trunk openโ€ (Figure 2) in the instrument cluster and โ€œFront Trunk Unlatchedโ€ (Figure 3) in the touchscreen should appear when the vehicle is in Drive.

 

  1. Step out of the vehicle and attempt to fully open the hood.

 NOTE: The primary hood latch should have released the hood to a partially open state.

  • If the secondary hood latch prevents the hood from opening fully (Figure 4), the hood latch is working as designed. Close the hood and discontinue this procedure.
  • If the hood opens fully (Figure 5), the secondary hood latch is NOT working as designed. Continue with one of the procedures as follows:
  • 2014 to 2016 Front Fascia Applique Vehicles (Nose Cone)
  • 2016 to 2021 Vehicles (Refresh)

 

2014 to 2016 Front Fascia Applique Vehicles (Nose Cone)

  1. Open the hood through the touchscreen (Figure 1) or key fob.
  2. Wrap the lower portion of the hood latch striker with a piece of masking tape where the hood latch engages with the striker, as shown (Figure 6).

 

  1. Remove the front underhood apron (refer to Service Manual procedure 12251002).
  2. Rotate the hood latch to the secondary position manually with a flathead screwdriver (Figure 7).

 

  1. Generously mark the top portion of the hood latch with a black marker (Figure 8).

 NOTE: Promptly proceed to the next steps before the ink from the black marker dries. Ink will transfer to the hood latch striker masking tape during the next step.

 

  1. Slowly close the hood latch to the secondary hood latch only (Figure 9).

 

  1. Open the hood through the touchscreen (Figure 1) or key fob.
  2. Measure with a caliper or ruler the distance between the rear of the hood latch striker and the bottom of the ink mark left by the secondary lever on the masking tape (Figure 10).

 

  1. Disconnect the hood latch electrical connector (Figure 11).

 

  1. Remove the bolts (x2) that attach the hood latch to the front end carrier (Figures 12 and 13).

 

  1. Determine the number of shims to be added to the hood latch bolts:
    • If the measured distance is 8โ€“9 mm: add 1 shim to each bolt.
    • If measured distance is 6โ€“7.9 mm: add 2 shims to each bolt.
    • If measured distance is 4โ€“5.9 mm: add 3 shims to each bolt.
  2. Position the shim(s) between the hood latch and the front end carrier, and then temporarily hand-tighten the LH hood latch bolt to the front end carrier. Repeat this step for the RH hood latch bolt.
  3. Secure the hood latch by fully pushing down on the hood latch assembly (Figure 14), and then tighten the hood latch bolts (torque 8 Nm).

 

  1. Connect the hood latch electrical connector (Figure 11).
  2. Remove the masking tape from the hood latch striker.
  3. Slowly close the hood latch to the secondary hood latch only and attempt to open the hood. Verify that the secondary hood latch securely holds the hood in place.
  4. Reinstall the components that were removed for access.

 

2016 to 2021 Vehicles (Refresh)

  1. Open the hood through the touchscreen (Figure 1) or key fob.
  2. Wrap the lower portion of the hood latch striker with a piece of masking tape where the hood latch engages with the striker, as shown (Figure 15).

 

  1. Remove the underhood storage unit (refer to Service Manual procedure 15242301).
  2. Rotate the hood latch to the secondary position manually with a flathead screwdriver (Figure 16).

 

  1. Generously mark the top portion of the hood latch with a black marker (Figure 17).

 NOTE: Promptly proceed to the next steps before the ink from the black marker dries. Ink will transfer to the hood latch striker masking tape during the next step.

 

  1. Slowly close the hood latch to the secondary hood latch only (Figure 18).

 

  1. Open the hood through the touchscreen (Figure 1) or key fob.

 

  1. Measure with a caliper or ruler the distance between the back of the hood latch striker and the bottom of the ink mark left by the secondary lever on the masking tape (Figure 19).

 

  1. Remove the bolts (x4) that attach the front fascia bracket to the carrier assembly (Figure 20).

 

  1. Position the front fascia bracket away from the carrier assembly by folding up 2 shop towels, and then insert them underneath and between the front fascia bracket and carrier to increase the gap between hood latch and fascia (Figures 21 and 22).

 

  1. Disconnect the hood latch electrical connector (Figure 23).

 

  1. Remove the bolts (x2) that attach the hood latch to the front end carrier (Figures 24 and 25).

 

  1. Determine the number of shims to the added to the hood latch bolts:
  • If the measured distance is 8โ€“9 mm: add 1 shim to each bolt.
  • If measured distance is 6โ€“7.9 mm: add 2 shims to each bolt.
  • If measured distance is 4โ€“5.9 mm: add 3 shims to each bolt.

 

  1. Position the shim(s) between the hood latch, retained spacers (Figure 26), and the front end carrier, and then temporarily hand-tighten the LH hood latch bolt to the front end carrier. Repeat this step for the RH hood latch bolt.
  2. Secure the hood latch by fully pushing down on the hood latch assembly (Figure 27), and then tighten the hood latch bolts (torque 8 Nm).

 

  1. Connect the hood latch electrical connector (Figure 23).
  2. Remove the masking tape from the hood latch striker.
  3. Slowly close the hood latch to the secondary hood latch only and attempt to open the hood. Verify that the secondary hood latch securely holds the hood in place.
  4. Reinstall the components that were removed for access.

 


Chronology :

– In January 2021, the Field Quality team investigated a Model Year (โ€œMYโ€) 2018- Model S vehicle whose frunk opened while in Drive. The secondary latch was found to be misaligned with the striker. The condition was recommended for study and engineering analysis.

– From April to May 2021, an engineering study was conducted on TeslaeBay logoโ€™s internal vehicle fleet. Results were inconclusive.

– From June to November 2021, a broader engineering study was conducted on customer Model S vehicles to understand the scope of vehicles potentially containing the condition.

– From November to December 2021, Engineering teams reviewed the study results and performed tests on secondary latch actuation, including an analysis of the probability of retention.

– In December 2021, TeslaeBay logo completed its investigation of records, related testing and analysis, and confirmed the root cause, risk assessment, and affected population.

– On December 14, 2021, a recall determination was made.

– As of December 20, 2021, TeslaeBay logo identified 4 warranty claims and 3 field reports (received between October 4, 2020 and December 20, 2021) that have been received for U.S. vehicles and are related to or may be related to this condition. TeslaeBay logo is not aware of any crashes, injuries, or deaths related to the condition.
