The buyer has the right to appeal to statutory liability for defects regardless of whether the product is sold with a warranty and whether the warranty has expired. The product's durability must correspond to what the consumer generally can reasonably expect from goods of that type.
The buyer can appeal to product defect even after the warranty period has expired if the product's service life in normal use is shorter than what the buyer could generally expect.
The buyer can report a defect not only to the seller, but also to a business that served as an intermediary in the transaction, a previous step in the sales channel and, if the product was covered by warranty, to the party that issued the warranty. The buyer is free to choose who to report the defect to. The party contacted by the buyer may not shirk from their responsibility and direct the claimant to another party.
The buyer must report defects within a reasonable time of noticing the defect or the time when the defect should have been noticed. Defects can always be reported at least up to two months after the buyer notices them.
