Hello Alfred,
are you getting confused between a warranty a and guarantee? A Warranty is statement about the conditions of a products at a particular point in time, and Guarantee is a statement from the guarantor of what action they will take if a prescribed set of conditions occurs. They are very different and have very different legal implications.
Under the Sale Of Goods Act(SoGA), A warranty is either written or implied that the new goods you have purchased were fit for purpose at the time and point of sale. If the goods prove otherwise, then you can expect the seller ( not the manufactuer unless you purchased directly) to remedy the situation. These are your statutory rights under SoGA. It is also worth noting that a warranty does not have a fixed period, but depending on the nature of the goods some warranty claims may be upheld for up to 6 years from date of purchase.
The manufacturers guarantee is a very different kettle of fish. Firstly it is not a legal requirement, and because of this the manufacture can stipulate almost any set of criteria about what is and is not covered. What they cannot do is to change the terms of a guarantee once it has been accepted or enacted.
If you believe the locker lid was faulty at the time of purchase, then your action should be against the seller, BUT because the product is more than 6 month old you will have to be able to prove the fault existed at the time of sale. Because warranty is part of your contract with the seller, the manufactures views on the condition or cause are not binding on you or the seller.
If you go down the Manufactuers Guarantee route, you are bound by the scope and limitations set out in the manufactures documentation you received with the new caravan.
Please note that the seller is the organisation or person you pay your money too for the product. If you used a finance house, they may be your seller rather than the dealer. If you intend to take any sort of legal action I recommend you seek professional legal advice.
