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.
Recall Bulletin: Recall Bulletins are mandatory service procedures that, unless they can be completed via a software update that a customer installs through the normal course of ownership, must be carried out by Tesla-certified Service Centers. Recall work performed by uncertified technicians could lead to unsafe conditions or voided warranty provisions.
Condition
Certain Semi trucks are equipped with a parking brake valve module that may intermittently not allow the operator to engage or disengage the parking brakes.
NOTE: The performance of the air brake system is not affected. Operators should monitor the side console parking brake switches and confirm the LEDs match the intended parking state per the Tesla Semi Operator’s Manual.
• If the valve does not allow the operator to disengage the parking brakes, the LEDs will remain on, indicating that the parking brakes have not disengaged.
• If the valve does not allow the operator to engage the parking brakes, the LEDs will remain off, indicating that the parking brakes have not engaged.
Correction
Replace the parking brake valve module.

Manufacturer Name : Submission Date :
Tesla, Inc. MAR 24, 2023 NHTSA Recall No. : 23V-205 Manufacturer Recall No. : SB-23-33-001 Manufacturer Information :
Manufacturer Name : Tesla, Inc.
Address : 1 Tesla Road
Austin TX 78725 Company phone : 6506815000
Population :
Number of potentially involved : 35 Estimated percentage with defect : 100 %
Vehicle Information : Vehicle 1 : 2023-2023 Tesla Semi Vehicle Type :
Body Style :
Power Train : NR
Descriptive Information : The subject population includes certain Tesla Semi trucks that were manufactured with certain parking brake valve modules as identified by the supplier. Affected vehicles were identified based on vehicle manufacturing records.
Production Dates : NOV 30, 2022 – FEB 28, 2023
VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect :
Description of the Defect : Certain Tesla Semi trucks are equipped with a supplier-provided electronically controlled parking brake valve module that may intermittently fail to transition when the parking brake is engaged or disengaged, which could then result in the parking brakes not being set or released.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : If the parking brakes are not engaged when the driver expects them to be and the driver releases the service brakes, the vehicle may unintentionally move, increasing the risk of crash.
Description of the Cause : The supplier’s specification may allow for excessive internal air leakage, which does not allow pressure to build properly. As a result, the valve module fails to transition when parking brakes are requested by the driver. Identification of Any Warning
that can Occur : When the parking brakes are not engaged, the LEDs on the side console
l remain off. Part 573 Safety Recall Report 23V-205 Page 2 Involved Components : Component Name 1 : Intellipark Valve Module

Avon Ohio 44011
Country : United States Chronology :
– On February 13, 2023, Bendix first communicated to Tesla their Safety Committee’s determination to file a recall for the involved component based on field issues Bendix observed from their customers. – On February 14, 2023, Tesla met with Bendix to review the issue in more detail and discuss Bendix’s recall determination. Shortly thereafter, Bendix filed a 573 Safety Recall with NHTSA for the component in question. – From February 14 to March 17, 2023, Tesla investigated the root cause and completed a risk assessment of the impact that the condition introduced in affected Tesla Semi trucks. – On March 17, 2023, Tesla completed its investigation, and determined to file a voluntary recall. – As of March 24, 2023, Tesla has not identified any warranty claims, crashes, injuries or deaths that may be related to such conditions. Description of Remedy :
Description of Remedy Program : At no cost to the customer, Tesla will replace the parking brake valve
module with a revised part with improved internals that prevent air leakage and allow the driver to engage and disengage parking brakes. Tesla does not plan to include a statement in the Part 577 owner notification about pre-notice reimbursement because there are no out of warranty repairs related to these conditions.
