Sony has expanded their free repair program for TOUGH CFexpress Type A memory cards following the discovery that more cards may be affected by a recognition and data-saving issue in cold temperatures. The problem, first acknowledged in June 2024, can cause certain CEA-G series memory cards to go unrecognized or fail to save images properly when operating near the lower limit of their recommended temperature range (14°F / -10°C).

Sony’s TOUGH CFexpress Type A memory cards were first introduced in 2022, offering a very solid build, fast read and write speeds, VPG400 certification, and more. Then, in 2023, they introduced the CEA-M models, which you can read about here. But as with all things meant to be better, faster, and stronger, companies occasionally run into issues. This includes SanDisk, which has had their own pains, most recently with the Canon EOS R5 Mark II.

TOUGH CFexpress Type A memory cards affected

Initially, Sony’s data-saving issue was reported for select Tough CFexpress Type A cards in 80GB, 160GB, 320GB, and 640GB capacities (models CEA-G80T, CEA-G160T, CEA-G320T, and CEA-G640T). However, Sony has now expanded the list of affected cards as of January 22, 2025.

Newly included are:

• 320GB cards with eight-digit lot numbers between 22040001 and 22080110 or nine-digit lot numbers between 220400010 and 220801100
• 640GB cards with eight-digit lot numbers between 22080001 and 22100136 or nine-digit lot numbers between 220800010 and 221001360

Sony confirms that memory cards with lot numbers starting with “3,” whether nine-digit or ten-digit, are not included in this program. Users can locate the lot number near the bottom of the back of the card.

Repair program is in effect until 2029

The free repair program remains in effect until June 29, 2029, under the terms of the memory card’s original Limited Warranty. Sony advises affected users to back up and erase all data before sending in their cards, as the repair process will result in complete data loss.

For full details on eligibility and how to initiate a repair request, customers should visit Sony’s support website or contact their regional Sony Support center.
