Questions & Answers about hoshoukikan no uchi ni shuuriirai o dashita hou ga ii desu.

What does 保証期間のうちに mean exactly?

It means within the warranty period.

Breaking it down:

保証期間 = warranty period
のうちに = during / within, before that period ends

So 保証期間のうちに gives a time limit: the action should be done before the warranty period is over.

Why is のうちに used here instead of just に?

のうちに adds the nuance of while that time still lasts or before it ends.

Compare:

保証期間に = at/during the warranty period
- grammatically possible in some contexts, but less specific here
保証期間のうちに = while still in the warranty period / before the warranty expires

In this sentence, のうちに is a very natural choice because the speaker is emphasizing that you should submit the repair request before the warranty runs out.

What is the difference between うちに and 間に here?
