The problem is a short-circuit in the anti-locking brake system. Water could get into the cars' ABS anti-lock brake systems unit, causing a short circuit and potentially a fire.
The first recall took place in March last year and concerned Corsa model Cs, Tigra Bs and Combo Cs with registrations beginning 53, 54 or 55.
The owners of more than 200,000 cars are being asked to bring their cars into dealerships for repairs, beginning next month.
A spokesman for Vauxhall said: 'The safety and quality of Vauxhall products remains our highest priority. We therefore consider any fault unacceptable. Further design improvements have been identified to address this condition.
"Vauxhall will contact all owners at the earliest opportunity recognising that a recall of this size must be completed in phases to ensure proper care of its customers, who are advised to continue using their vehicles in the normal manner."
