Here is the list of 5 labels for Model 3 Battery & Charging issues, including the major 2025–2026 recall for power loss:
High-Voltage Contactor Failure,
Cause: A 2025–2026 recall affects roughly 13,000 vehicles (including 2025 Model 3s) due to faulty solenoids in the battery pack contactor that can unexpectedly open.
1 Solution: Tesla service centers replace the faulty contactor with a certified part (part number 1089334-01-K) to prevent sudden loss of propulsion power while driving.
2
BMS Calibration Drift (LFP Batteries),
Cause: In RWD models with LFP batteries, the voltage curve is flat, making it hard for the Battery Management System (BMS) to estimate the exact state of charge without regular full charges.
Solution: Tesla recommends charging to 100% at least once per week. This allows the BMS to "re-index" and prevents the car from shutting down unexpectedly when the display shows a remaining percentage.
Charge Port Latch & Pin Errors,
Cause: Debris, ice, or a faulty locking pin (Error CP_A163) prevents the charging cable from locking into place, which stops or significantly slows the charging session.
3 Solution: Inspect the port for obstructions or clean the pins with compressed air. If the internal latch motor has failed, the charge port assembly must be replaced.
Low Voltage (LV) Battery "Sleep" Issues,
Cause: The 16V Lithium-Ion accessory battery can be drained by parasitic draws from third-party apps or Sentry Mode, leading to a vehicle that won't "wake up" or open doors.
Solution: A software patch optimizes the DC-DC converter to maintain the LV battery more aggressively. If the battery is damaged, it requires a specialized 16V replacement from Tesla.
Supercharging Thermal Throttling,
Cause: Charging speeds drop significantly (often to 30–50kW) if the battery is too cold or if the cooling system is struggling during extreme heat.
Solution: Always use the in-car Navigation to the Supercharger to trigger "Preconditioning." This warms or cools the battery to the optimal $50^\circ\text{C}$ ($122^\circ\text{F}$) for maximum intake speeds.
