Nissan Juke: Bad Timing Chain - Who is responsible

I have a Nissan Juke 1.2 Accenta+ 2016 module. The car has less than 50 000Km on it and it started to make a noise from inside the engine. I asked around and everybody told me that it is the timing chain. many could not understand why the timing chain could be the problem as it is suppose to give problems at around 120 000Km. i took the car in to Nissan and they confirmed it is the timing chain and want to charge me about R20 000.00 to for the repairs. I am not very happy with this. can you, as Nissan, please give an answer and what you will do regarding this challenge
