The instrument panel that shows the speed and battery capacity went blank and was black. The car still drove and I was only 4 miles from home. I was not able to tell what speed I was traveling at, what warning condition or alarms may have been triggered and I did not know what the charge was on the car.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford OTASU6140F150L a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the OTASU6140F150L repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does OTASU6140F150L cover?
The manufacturer filed it against 2 model years: 2023 Ford F-150 Lightning, 2022 Ford F-150 Lightning. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
