NHTSA Service Bulletin 11024894: 2023-2025 Ford Mustang Mach E
Official manufacturer communication context for 2023-2025 Ford Mustang Mach E, with affected products, buyer checks and links into Carchieve recall, problem and VIN research.
Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
Some 2023-2025 Mustang Mach-E vehicles equipped with a lithium iron phosphate (LFP) standard range battery (minor feature code HTHAH) built on or after 23-Jun-2023 may exhibit a condition where the displayed high voltage (HV) battery state of charge (SOC) percentage has a sudden reduction greater than 10% while driving. At low SOC, this may also result in a reduction of vehicle power with a turtle light displayed in the cluster. This concern may occur if the vehicle has not been charged to 100% for an extended period of time as this leads to an inaccurate displayed SOC. Advise customers to charge their vehicle to 100% at least once per month to reset the SOC measurement or more often if the condition persists. To confirm a vehicle is built with a certain minor feature code, review the build information by double-clicking the vehicle identification number (VIN) in the upper left corner in the Professional Technician System (PTS).
What this bulletin may mean before buying
Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
