If a vehicle is recalled then the manufacturer has an obligation to notify owners of the vehicle, explain any risks and arrange rectification to be carried out at no expense to the owner. If the vehicle is no longer suitable for your needs, it could be argued that you have grounds to reject the vehicle. However, that the vehicle is approaching two years old would make this less likely, and it is possible that the dealer would refuse an attempt to reject given that the issue is a temporary fault which can and should be rectified rather than an individual issue. Typically the owner is expected to give the dealer an opportunity to rectify the issue before attempting to reject the vehicle. However we would suggest asking the dealer for a courtesy/replacement car that will cover your needs while you await the fix.
