Why This Matters
Tesla has issued Service Bulletin SB-24-39-003 for specific 2024 Cybertruck Tri Motor vehicles. While this is classified as a non-safety-related campaign bulletin, it addresses a critical component—the Front Drive Unit (FDU)—that does not meet the manufacturer's quality standards. Ensuring all vehicle components meet Tesla's specifications is crucial for optimal performance, reliability, and longevity of your vehicle. Addressing this proactively helps maintain the high engineering standards expected from a Tesla Cybertruck.
What's Being Addressed
This service bulletin focuses on certain 2024 Tesla Cybertruck Tri Motor vehicles equipped with a Front Drive Unit (FDU). The core issue is that an internal component within the FDU does not comply with Tesla's stringent specifications. This condition necessitates the replacement of the affected FDU with an updated part that meets all required manufacturing and performance criteria. This ensures that the Tesla Cybertruck Front Drive Unit operates as intended.
Repair Procedure Summary
The repair involves a multi-step process performed by a Tesla service technician to resolve the Tesla Cybertruck Front Drive Unit issue.
- Software Update: The vehicle's software must first be updated to the latest available version. Technicians will refer to Service Manual procedure 00020003 for this step.
