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.

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. Follow up with the customer to confirm the appointment once OASIS confirms software availability.

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.

There is expected to be a low number of vehicles found with a concern door handle. In some of the affected vehicles, the interior door handle may have excessive material present on the door handle cavity. This can cause the door handle cable to bind during operation. If the cable binds, it may result in a door that cannot be opened from the inside. The door can still be opened using the exterior door handle. It is also possible that the door cannot be closed. If the door will not close, the instrument cluster will illuminate with a Door Ajar warning
