BYD vehicle owners in Brazil report widespread internet connectivity failures

BYD vehicle owners in Brazil have reported persistent internet connectivity issues affecting various models over several weeks. The failure involves the Claro data chips installed at the factory, which has disabled essential features within the BYD application.

Impacted functions include monitoring battery charge levels and performing over-the-air software updates. Owners have reported that while the mobile application itself remains functional, the 4G connection to the vehicle is lost, preventing full use of the car’s digital systems.

Reports from multiple regions, including Minas Gerais and Maranhão, indicate that dealerships and customer service departments have attributed the problem to instability in the Claro network. However, users have expressed frustration over the lack of a clear resolution timeline and a perceived lack of direct communication from BYD regarding the technical fault.
