Dear Valued Sony Customer,
There may be issues with certain CEA-G series memory cards, where the memory cards are not recognized, or the image does not save correctly in low-temperature conditions. The issue may occur around the lower limit of the recommended operating temperature range (14° Fahrenheit, -10° Celsius).
To address this issue, we will repair affected memory cards free of charge until June 29, 2029, subject to the terms and conditions of the memory card's original Limited Warranty.
