dejadeadnz: This is quite possibly less than 3 years old. If it's for personal use, I'd say the CGA and its requirements in respect of goods being of acceptable quality has you more than covered.
Even if it was older, if it is a known fault that could develop, it should be covered too, as goods must be sold free of minor defects, and this isn't really minor either. Many companies will issue recalls when they identify a fault with a batch (eg car manufacturers), while some will only fix peoples goods that are affected over time, if they don't think it will affect everyone who purchased from the batch.
