- Medium severityFrequency: OccasionalRenault Arkana12 V battery drain while the car is parkedSeveral Arkana owners report the 12 V battery going flat after just a few weeks, or even a single battery being replaced twice in a year; Renault has not publicly acknowledged excessive drain at rest, so we treat this as reported by owners and not as a confirmed fault.

- Medium severityFrequency: OccasionalRenault Captur II12 V battery drain while the car is parkedSeveral Captur II owners report the 12 V battery going flat after a few days parked, without Renault having publicly acknowledged excessive drain at rest; there is no press study confirming it as a pattern, so we treat it as reported by owners.
