Not a response to the specifics of the case, but to your comment in general...
A warranty is a cost to the company. Any warranty period increases the price of the product. For example, think of a one year warranty. In order to cover the costs of the warranty, Apple has to compute the probability of failure within the first year. Then, multiply that by the average cost of replacement/repair and add that to the cost of a consumer good.
For a five year warranty period, that probability grows substantially. Hence, the cost of a product covered by a five year warranty will be higher than a product covered by a one year warranty. It's why extended warranty products like AppleCare cost money.
Alternatively, a company might use higher quality products/better quality control to reduce the probability of failure during the five year period. But doing so increases the price of the good as well. There is no free lunch.
Hence, this kind of legislation has one impact: increasing the price of consumer goods. Moreover, it removes the ability for paying customers to choose a cheaper product that might fail after a year over a more expensive one that might fail after five. What is reasonable should be dictated by the consumer not by some government legislation.
