Ford Fusion gear shifter knob won’t unlock in hot weather despite fuses and brake pedal switch being checked on Ford Fusion

Some Ford Fusion owners report experiencing issues with the gear shifter knob being locked in Park during hot weather, despite checking fuses and the brake pedal switch. This problem, which affects late model Fords, can manifest as a rotary gear shifter that is stuck or stiff when attempting to move into Reverse or Drive. Additionally, some owners have noted that improper shifting may be linked to a faulty transmission sensor or low transmission fluid levels. To resolve these issues, it is recommended that owners have their vehicle inspected by a qualified technician to diagnose any underlying problems, particularly those related to the transmission system or gear shifter assembly.
