On certain Cybertruck vehicles, the AC junction box to fast charge contactor HV harness might have a poor crimp connection, which may cause increased resistance and localized heating in the harness. If the ancillary cover is removed for other procedures, replace the AC junction box to fast charge contactor HV harness with version -J or later.
full bulletin at NHTSA ↗On certain Cybertruck vehicles, the left body controller's printed circuit board was misaligned with its heatsink, which may cause the board to crack when the enclosure is closed. This may lead to a graceful power-off event.
full bulletin at NHTSA ↗Tesla identified a manufacturing flaw in certain Cybertruck vehicles. Driving range and performance can be impacted by this high voltage battery issue. Tesla is replacing high voltage batteries for impacted vehicles free of charge.
full bulletin at NHTSA ↗On certain Cybertruck vehicles, the HV battery ancillary harness may have been improperly routed, which might strain the harness branches and/or connectors between the High Voltage Controller (HVC) and Battery Management Boards (BMBs), potentially preventing HVC and BMB communication through one of the two harness branches.

Owners report two types of electrical system catastrophe with the 2024 Cybertruck: complete loss of vehicle mobility and entrapment during emergencies.
The most severe claim involves a collision where the vehicle's electric door system lost power after impact. With no exterior door handles and manual release mechanisms hidden beneath panels with no instructions, occupants became trapped. Armored glass windows resisted forced entry by rescue personnel. The fire spread rapidly, and one occupant died from smoke inhalation and thermal injuries.
The Power Conversion System (PCS2) is failing broadly. Multiple owners report complete AC charging failure around 30k–46k miles with fault codes PCS2_a094, PCS2_a095, and PCS2_a103. Vehicles become stranded at low state of charge with no ability to charge at home or at public networks. No prior warning precedes failure. Service centers acknowledge the issue but do not issue a recall. Replacement costs roughly $7,000, and replacement parts are on national backorder.
Full Self-Driving software has disengaged unexpectedly during highway operation, causing abrupt acceleration and near-miss collisions with oncoming traffic. Service logs show no error records of these disengagements. V14 software also operates 7 mph above posted speed limits by design with no driver override.
Other reports include FSD's failure to detect a decelerating vehicle ahead, resulting in a three-vehicle collision with airbag non-deployment, and side mirrors striking objects with no detection by the vehicle's safety systems.
Electric-only door and window systems fail when vehicle power is lost following collision or impact. Manual release mechanisms exist but are hidden beneath panels with no instructions. Exterior door handles are absent; only a button at B/C pillars operates doors when power is available. Armored glass windows resist forced entry by rescue personnel. This design creates foreseeable occupant entrapment risk.
When: Upon impact and power loss; rear windows jam/freeze during normal operation
Symptoms owners cite: Doors and windows inoperable after power loss; Passenger unable to exit vehicle after crash; Rescue personnel unable to open doors from outside; Armored glass resistant to breaking; Rear windows jam or freeze when closing rear doors
Repairs/costs cited: Manual release mechanism exists beneath panel but requires knowledge of location and operation; no permanent design fix reported
Recalls/TSBs owners mention: No recall or urgent fix reported; Tesla has not issued guidance on manual release procedures
FSD system disengages suddenly and independently during operation, causing vehicle to abruptly accelerate. Incidents occur at various speeds including 49 mph and 70 mph. Vehicle veers into oncoming traffic in multiple instances. System logs show no error records of disengagement event. Service unable to duplicate or diagnose failure.
When: Various speeds, 2,000–5,149 miles
Symptoms owners cite: FSD disengages independently without driver input; Abrupt acceleration during or immediately after disengagement; Vehicle maneuvers into oncoming traffic; Near head-on collisions avoided by manual intervention; No system logs record the failure
Repairs/costs cited: Dealer unable to duplicate or diagnose; vehicle not repaired
Recalls/TSBs owners mention: Service advisor states no errors in system logs; no diagnosis or repair performed
Full Self-Driving V14 software automatically operates approximately 7 mph above posted speed limits on all road types without driver input. No setting allows driver to enforce strict compliance with posted limits. Available speed settings only permit equal to or greater deviation above limit. Driver cannot command system to remain at or below posted limit while FSD is active; only option is full disengagement. Behavior is intentional design, not malfunction.
When: V14 software implementation
Symptoms owners cite: Automatic speed 7 mph above posted limit; Affects all road types including city streets and highways; Occurs without driver selection or input; Driver cannot manually lock compliance to posted limit; Drivers receive citations despite not intentionally selecting unlawful speed
Repairs/costs cited: No repair available; behavior is programmed design of V14
Recalls/TSBs owners mention: No manufacturer response regarding this design choice reported
Complete failure of onboard charger and AC charging system with error codes PCS2_a094 (AC Charging unavailable), PCS2_a095 (Powershare unavailable), and PCS2_a103 (IsoTempSensorIrrational). Vehicle cannot charge via home AC or public AC chargers. DC charging may remain functional. Failure occurs with no prior warning. Multiple owners report similar failures around 30,000–46,500 miles. Replacement cost approximately $7,000. Replacement parts reported on national backorder.
When: Around 30,000–46,500 miles; failure at 7,500 miles also reported
Symptoms owners cite: Unable to AC charge from home charger; Unable to AC charge from public/supercharger networks; Fault codes appear on touchscreen with no prior warning; Vehicle effectively stranded at low state of charge; System reboots do not resolve fault; AC charging amperage drops (e.g., 48 amps to 24 amps, then complete failure)
Codes mentioned: PCS2_a094, PCS2_a095, PCS2_a103
Repairs/costs cited: Requires replacement of PCS2/onboard charger module; reported cost $7,000; parts on national backorder
