On the 2025-2026 Opel Frontera, owners of early Frontera Electric and Frontera Hybrid cars report a cluster of software-level defects on the German owner forum. On the Electric, the three-phase on-board charger hangs when the charge current is stepped down to 6 A or lower (as happens with load management or solar surplus charging), the passenger airbag warning lamp stays on permanently, the tailgate is falsely detected as open which then blocks the central locking, and USB software/map updates are recognised but fail to install. Across Electric and Hybrid cars owners also report the My Opel app failing for preconditioning and charge monitoring, Apple CarPlay dropping the connection, remote locking not responding after shutdown, voice control not working without a paired phone, auto high beam that cannot be re-enabled after manual deactivation, and missing menu items such as live Wh/km consumption. At least one owner's faults were cleared by a dealer software update applied over OBD.

How to Fix
Ask the dealer to apply the latest body control module and infotainment/telematics software over OBD rather than waiting for an over-the-air update, and have the fault documented in the service record. For the charging dropout, avoid setting wallbox current below the level at which the charger hangs until the update is applied. Check with the dealer which functions are software-locked in your build year rather than assuming a hardware fault.
