Sarah buys herself a brand new car. On the first day, the indicators don't work; the seller repairs them. On the second day, the headlight won't work. She returns it, and it is repaired again. On the third day, the driver seat gets stuck in the wrong position, and it takes two days for it to be repaired. Once it is returned to her, she discovers that the headlights are not working again, and she is very unhappy and wishes to return the car. However, the seller says the faults are not material breaches, and she cannot do so.

Question 1: Explain to the seller why under the Consumer Rights Act 2015, this is incorrect.
