With cautionCars built before 2022 may have two outstanding campaigns: one for a high-voltage power cut (2022) and one for battery control calibration (2023). Check with the VIN that they were carried out. The battery, on the other hand, holds up well: Aviloo measures a median of 94% at 50,000 km and 90.7% at 150,000 km in the e-208 and Corsa-e.[2][3][4]

With cautionThis generation is still recent: there are few owner reports and only one campaign of its own (Astra Electric, 2023), but it also inherits the charger and power electronics design of the first. Check for campaigns and remaining warranty.[5][6][7]
