Summary
Some 2018-2021 Ford/Lincoln vehicles equipped with a wireless charging pad may exhibit an inoperative charging pad, slow charging, a notification that the phone has been mispositioned on the charging pad and/or the phone charging icon in the center screen is not showing. This may be due to the customer's phone if they are using an iPhone 12. Vehicles equipped with a wireless charging pad are designed to charge best with phones that follow the Qi standard. The iPhone 12 hardware currently does not follow the Qi standard for wireless charging. This may make it difficult for Ford and Lincoln vehicles to wirelessly charge this specific phone. The phone can still be charged using the USB cable if the vehicle experiences the above symptoms. If the customer is using an iPhone 12, verify the wireless charging pad works with a Qi certified phone prior to any part replacements.

Summary
Some 2021 Bronco vehicles equipped with Big Bend and Outer Bank trim levels may exhibit a whistle noise originating from the front of the hood area when traveling at speeds above 30 mph (50 Km/h). If the whistle noise can be eliminated by taping off the gap between the hood and grill opening, this condition may be due to the hood seal design. Hood seal replacement will not resolve this condition. Inform customers that they can continue to drive the vehicle and Ford is currently working to release an improved seal design that will be available in October 2021. Follow up with the customer to schedule an appointment once OASIS confirms part availability.

Summary
Some 2021 Mustang Mach-E, F-150, Edge/Nautilus or Bronco vehicles equipped with SYNC 4 may have a customer symptom of the SYNC voice commands being activated without pushing the steering wheel switch. This may be due to the feature called Wake Word within SYNC 4. This feature allows the driver to activate the SYNC 4 system without pushing the steering wheel switch. Under the touchscreen Settings > Voice Settings the preferred Wake Word can be changed. The feature can also be disabled if the customer does not want the SYNC voice commands being activated without touching the steering wheel switch. This feature is not a defect. Do not submit a claim for this condition.

Summary
Some 2021 Bronco vehicles equipped with exterior zone lighting may experience an intermittent single hazard lamp flash when hazards are off. This condition is due to the body control module (BCM) software. This condition occurs when zone lighting is activated then deactivated while the engine is OFF, or during an engine auto-start-stop event. This condition may be temporarily suppressed by activating then deactivating the zone lighting feature while the engine is running. Module replacement will not resolve this condition. Ford is currently working on a software update that is expected to be available October 2021. The customer can continue to drive the vehicle and schedule a follow-up appointment for October, when repairs are expected to become available.

Summary
Some 2021 Bronco vehicles equipped with front and rear parking aid sensors may set diagnostic trouble codes (DTCs) for all 8 parking aid sensors/circuits if 2 or more rear parking aid sensors/circuits have a concern. This is due to the software within the parking aid module (PAM), and module replacement will not resolve this condition. If the PAM sets DTCs for all 8 parking aid sensors/circuits, diagnose the rear parking aid sensor and circuit DTCs first. Reference Workshop Manual (WSM), Section 413-13A for parking aid diagnostic information. Ford is currently working on a software update that is expected to be available August 2021. The customer can continue to drive the vehicle and schedule a follow-up appointment for October, when software is expected to be available. Follow up with the customer to confirm the appointment once OASIS confirms software availability.
