What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationPicked out of NHTSA’s summary below, word for word. The document itself is the record, and the dealer checks the VIN.

The update is downloaded and installed in the background. During installation, the system can be used without restrictions. The new software will become active after the vehicle has been restarted. MBUSA will conduct an OTA service campaign. Remote software updates are automatically downloaded and installed in the customer’s vehicle free of charge and do not require a dealer visit. No customer letter will be mailed for this OTA software update.

What owners reported
Source: NHTSA complaint databaseOwners of the 38 model years this bulletin names have filed 794 complaints with NHTSA since 2015. 176 of them name Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2020 Mercedes-Benz GLE-Class, the 13 owners who gave an odometer reading for Electrical System reported it at a median of 6,615 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
During regular use my 2023, Mercedes Cla 250, had a fault in the instrument display in which the display shut off completely. Only the media display remained on, however the media display is completely useless in this scenario, only the instrument display can show the speed in which the vehicle is traveling and the Rpm range in which the…

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz OTA - 24P5497745 a recall?
No. A over-the-air update 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 OTA - 24P5497745 repair free?
A over-the-air update is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does OTA - 24P5497745 cover?
The manufacturer filed it against 41 model years across 2 brands (Mercedes-Benz and Mercedes-Maybach): 2022 Mercedes-Benz A-Class, 2021 Mercedes-Benz A-Class, 2020 Mercedes-Benz A-Class, 2024 Mercedes-Benz AMG GT, 2023 Mercedes-Benz AMG GT, 2022 Mercedes-Benz AMG GT and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
