This is the second time reported on the forum that a caravanner has had a product failure, which has put the seller in breach of contract, and the customer has ended up paying to have the repairs done.
That is not a win win.... Did the customers ask the dealer's to supply faulty goods when they placed their orders for the caravans? The CRA is very clear that retailers must supply new goods, that are free from design, material or workmanship defects.
If the dealer fails to ensure the goods are in good condition, that is their failure not the customers.
Of course in reality it would be unreasonable and impractical for a dealer to inspect every part down to the nails and screws that go into a caravan, which is why when they become a dealer for a brand, as part of their contact with the manufacturer they should seek assurances from the manufacturer about the quality of the goods they receive, such that it does not require the dealer to strip every part down to its base level. But the law expects and requires that level of diligence in a retail sale.
The fact that faulty goods get through the dealership to the end user, point to the conclusion the dealership has failed in their duty to ensure the goods are fault free. And that is the breach of contract under the CRA.
As far as the customer is concerned, the dealer has not performed their legal duty which has led to the faulty parts being delivered.
The Dealer either needs begin to be more diligent when preparing goods for sale, or to be more forceful in their own contractual arrangements with their own suppliers or manufactures about the quality assurances of supplied goods, and how suppliers will be held responsible for faults they allow through their own hands.
Consider this scenario:-
Two customers decide to purchase identical caravans from the same dealer at the same time. Both caravans are delivered and are used identically. One caravan develops a fault which the manufacture accepts was their responsibility and they supply replacement parts foc, but the dealer charges the customer to fit them.
Is it fair or reasonable that this customer should end up paying more for his caravan than the other customer who has not suffered the inconvenience of the fault? Why should the customer end up paying not only for the incompetence of the manufacturing fault and the dealers failure to prevent the faulty goods from being delivered, The CRA is designed to level the playing field such that neither customer should disadvantaged.
Bear in mind The CRA is immutable, and nothing in a retail contract can diminish your rights under the CRA. If it ensures the repairs are carried out then pay dealer, but after completion, consider starting a CRA claim through the small claims court to recover the money you paid.
You the customer have been wronged, why should you pay anything when it's the dealer that has failed in their duty.
I strongly advise you seek professional advice on this matter.
