  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,...
