First up @Fedupwtbs, sorry to hear you are having major problems with a relatively new car.
Could I point out that your contract is with the original dealer, the one that sold you the car. If Seat Ireland is willing to pick up part of the expense of the repair, then that is to their credit, but your issue is with the original dealership - they got your money.
Any warranty given with a car is in addition to your statutory rights as a consumer in Irish / EU law and cannot replace or diminish them.
Under the [broken link removed], the car you were sold must meet three criteria. It must be:
- of merchantable quality
- fit for purpose
- as described.
If it fails any of these criteria then you may have legal recourse against the seller.
A reasonable person would expect a car, purchased new from a main dealer, properly serviced over two years with correct parts, etc to continue to work as a car without developing major repair problems. If the make / model of car has a demonstrable history of developing faults then that strengthens your case if that information was not supplied to you at the time of purchase.
Was that Seat the subject of a recall for warranty work in other EU states for faults like your car has? Is the repair a serious safety issue (brakes not working, engine cutting out, etc) that could endanger the driver or occupants? Any of these issues will also add weight to a case for free repair / compensation
I believe you need to consult [broken link removed] as a first step and see if my opinion is valid and take the steps suggested if you believe it is.
