Diesel repeatedly leaking into sump

Since buying the car in Jan 2015 it has suffered from diesel leaking into the sump from the fuel pump on 3 occasions. On the first 2 occasions the pump was replaced under warranty after being off the road for a month and it is in the workshop now to rectify the latest occurrence.
I now have no confidence in the car and when it happened on New Years Eve at 70mph on a motorway the smoke obscured the carriageway putting other road users and my family at risk. Do I have grounds for getting Hyundai to replace the car or buy it back at the purchase price?

You probably do. The problem must be due to a malfunction of the programmed active regeneration of the DPF during which extra fuel is pumped into the engine to fire and burn off the soot in the DPF. Obviously having had a year's use out of the car you can only expect 'market value', not what you paid for it. Law here: www.honestjohn.co.uk/faq/consumer-rights/ I'm assuming the car was new in January 2015.
