2022 FORD MUSTANG MACH-E

Symptoms: Complete loss of power while driving, Vehicle won't start or go into ready mode, Wrench light with no codes or generic HV system faults, Clicking from under vehicle near battery pack

Fix: HVJB is mounted under the vehicle and houses contactors, fuses, and control logic for the high-voltage system. Failures often traced to moisture intrusion or internal contactor welding. Replacement requires pack isolation, underbody access, about 4-6 hours labor. Ford has issued TSBs and extended warranty coverage on some VINs through 22S56.

Estimated cost: $2,500-4,000

Symptoms: Dead 12V battery after sitting 2-5 days, Vehicle won't wake up or unlock, Repeated battery replacements don't fix the problem, SYNC screen frozen or black on startup

Fix: The DC-DC converter charges the 12V system from the HV pack, and early software calibrations had parasitic draw issues or converter faults. Ford released multiple OTA updates (Power-Up 3.6.0+) addressing this. If software doesn't fix it, DC-DC replacement is 3-4 hours labor. Some cases also involve gateway module reflash.

Estimated cost: $800-1,500

Typical onset: 30,000-60,000 mi

Symptoms: Whining or grinding from rear on AWD models, increases with speed, Gear oil leak visible at rear motor seals, Vibration during acceleration

Fix: Ford issued recall 22S45 for rear drive unit bearing failure risk. Affected units get full drive motor replacement (R&R plus new unit). Job takes 6-8 hours including coolant system bleeding and alignment checks. Most covered under warranty or recall, but out-of-pocket it's steep.

Estimated cost: $4,500-7,000

Symptoms: SYNC 4A screen unresponsive or black, Backup camera won't display, Climate controls inaccessible, System reboots randomly while driving

Fix: Usually software-related; hard reset (hold volume down + skip forward for 10+ seconds) or OTA update resolves most cases. Persistent failures can require APIM (module) replacement, 2-3 hours labor with programming. Ford has released multiple SYNC updates addressing stability.

Estimated cost: $150-300

Typical onset: 40,000-80,000 mi

Symptoms: Charge door won't open electrically, Door stuck open or closed, Repeated open/close cycling on its own, Error message: 'Charge port door fault'

Fix: Electric latch motor or microswitch in the charge port door assembly fails, sometimes from ice/water exposure. Replacement involves rear quarter trim removal, 1.5-2 hours labor. Part availability has been spotty, so lead times can stretch.

Estimated cost: $400-700

Symptoms: Clunking from front suspension over bumps, Steering feel changes or looseness, Visible gap at subframe mounting points

Fix: Ford recalled certain 2021-2022 Mach-Es for improperly torqued front subframe bolts that can loosen and separate. Inspection and re-torque per service bulletin, about 1 hour labor. Critical safety issue if unaddressed—can lead to loss of steering control.

Estimated cost: $0

Symptoms: Weak or no heat in cold weather below 20°F, Range drops dramatically in winter, Compressor noise changes or stops, Defrost barely functions

Fix: Heat pump system (optional on Premium/Select, standard on GT) can fail due to refrigerant leaks, compressor clutch issues, or control valve faults. Diagnosis requires AC machine and thermal imaging, repair is 4-6 hours including refrigerant recovery/recharge. Some cases covered under emissions warranty (8yr/80k mi).

Estimated cost: $1,800-3,200
