Common Problems with the
2026 Volvo C40 / EC40 (Recharge)

Volvo Owners Club threads describe C40 Recharge / EC40 cars diagnosed with an AC module fault within the onboard charging unit, where AC charging will not be accepted even though DC charging still works. The OBC module costs roughly £1,600 plus labour, and Volvo Owners Club members cite quality bulletin P10077 and report the fault can recur. There is no eight-year warranty on the charging module unlike the battery, so an unresolved OBC fault is an expensive out-of-warranty liability on a used EC40.

Volvo Owners Club threads describe C40 Recharge / EC40 infotainment systems defaulting to Battery Save Mode after short journeys, so cameras and the centre screen take minutes to reload, with dealers attributing it to the 12V battery not charging on short trips. Owners report the fault returning after software updates and battery replacements. For a used buyer, a central screen that reboots or cameras that are unavailable is a genuine usability issue.

Auto Express’s EC40 review finds you are not short of toys but most of the climate settings live behind the touchscreen, which they call a frustration while driving, and note the system took a long time to set up and a noticeable pause before the sat-nav surfaced addresses even though screen loading is otherwise good. Parkers similarly lists an infotainment that is starting to show its age. None of it stops the car working; it does decide how it feels on a wet, busy run - so drive it through the daily routine before buying.
