Sony Alpha Wi-Fi and Bluetooth unit malfunction is a defect that surfaces on some Sony Alpha cameras after a firmware update, when the camera displays the on-screen message The Wi-Fi/Bluetooth unit has malfunctioned and stops working on the wireless network.[1] Sony's support article 00342252 tags three bodies, the ILCE-1 (Alpha 1), the ILCE-9M3 (Alpha 9 III), & the ILCE-7SM3 (Alpha 7S III), states the message appears only when a hardware problem is detected, not a software problem, & tells owners they will not be able to use the network functions & should take the camera in for inspection.[1] In the one repair case documented by a named publication, the affected camera was a used Sony FX3 whose fix required replacing the main board; Sony first quoted at least $700 for it.[2]
Background
The Sony Alpha 7S III (model ILCE-7SM3) is a full-frame mirrorless camera that Sony supports through downloadable firmware updates posted on its own support pages.[3] Sony's firmware updates for the a7S III added support for Sony's Creators' App, the mobile application that Sony documents as the replacement for the older Imaging Edge Mobile app, along with the Monitor & Control app, WPA3-SAE wireless security, & FTP transfer changes.[3] Sony released firmware Ver. 3.01 for the a7S III on May 15, 2024.[3]
Sony presents these updates as a one-way path. The firmware page instructs that Updates should be installed in chronological order, lists only forward upgrade steps, & offers no download to roll a camera back to an earlier version.[3] The Ver. 3.01 release notes describe the changes as improvements, including a line that the update Fixes an issue where the camera may not be able to connect to the network & one that it Improves the operational stability of the camera.[3]

The malfunction message
Sony documents the error in support article 00342252.[1] The article states that with the latest firmware, the message appears if a hardware error related to the network function is detected when the Wi-Fi or Bluetooth function is turned on, & that it is displayed only when a hardware problem is detected, not a software problem.[1] The same article tags three affected bodies: the ILCE-1, the ILCE-9M3, & the ILCE-7SM3.[1]

The instruction Sony gives the owner is to bring the camera in. Sony's support article states:
You can continue shooting by pressing OK, but you will not be able to use the network functions, so we recommend that you take the camera in for inspection as soon as possible.
The wireless loss covers both Wi-Fi & Bluetooth, the two functions a working unit handles for image transfer, remote control, & app pairing.[1]
The message was public by April 26, 2024. On that date Sony Alpha Rumors reproduced Sony's wording, matching the support article text word for word, & tied the warning to the Alpha 1 (ILCE-1) Ver. 2.01 firmware update.[4]
Firmware updates and pulled releases
The malfunction sits inside a run of Sony firmware that the company pulled in 2024.[2] PetaPixel reported that Sony pulled the Alpha 1 firmware Ver. 2.00 in March 2024, then pulled the Alpha 7R V (ILCE-7RM5) Ver. 3.00.[2] Sony's stated reason for the Alpha 7R V withdrawal, quoted by PetaPixel, was a startup failure.[2]
On its support page, quoted by PetaPixel, Sony said that some ILCE-7RM5 cameras may not start up after installing the version 3.00 update and that it had suspended the update while we investigate the cause.[2]
PetaPixel reported that Sony also pulled the FX30 update after distributing it.[2] By PetaPixel's account, Sony had needed to pull firmware repeatedly across 2024, & the frequency of the problems concerned some Sony owners who use the cameras for paid work.[2]
Repair cost and warranty response
The one repair walked through by a named publication is the Sony FX3 of YouTuber Cory Mayo, of the channel Camera Nerds Media.[2] PetaPixel reported that Mayo bought a used FX3, that the camera was ruined when he tried to update it, & that Sony first quoted a repair cost of at least $700.[2] The eventual repair, per PetaPixel, comprised replacing a Wi-Fi module, the camera's main board, and an optical filter block & cost a little over $300.[2]

PetaPixel noted:
The issues with Mayo's FX3 went beyond a firmware update, although that's when the camera's usability was compromised.
The FX3 is a distinct model from the three bodies tagged in support article 00342252,[1] & PetaPixel does not use the exact Wi-Fi/Bluetooth unit has malfunctioned wording.[2]
Sony's own support article carries no recall, no affected production range, & no serial range; it names the three models & directs owners to inspection.[1] The firmware page provides only forward updates, offers no rollback download, & instructs that updates run in chronological order only.[3]
EU and US warranty law
EU Directive 2019/771 governs certain aspects of contracts for the sale of goods in the European Union.[5] Article 10(1) provides that the seller is liable to the consumer for any lack of conformity which exists at the time the goods were delivered & becomes apparent within two years of that time, & states that this paragraph also applies to goods with digital elements.[5] Article 11(1) provides that a lack of conformity which becomes apparent within one year of delivery is presumed to have existed at the time of delivery, unless proved otherwise or unless the presumption is incompatible with the nature of the goods or the defect.[5] Article 11(2) provides that Member States may maintain or introduce a two-year period in place of the one-year period in Article 11(1).[5]

In the United States, the federal warranty statute is the Magnuson-Moss Warranty Act, codified at 15 U.S.C. ch. 50 beginning with Section 2301.[6] Section 2301 defines a consumer product as tangible personal property normally used for personal, family, or household purposes, defines a written warranty & an implied warranty, & defines the Commission as the Federal Trade Commission.[6]
