Nice knowing that, in addition of three failing keys (u, i and o) and one failed speaker, I can also expect the display flex cable to fail. 2017 MBP that's been plagued with problems from the very beginning.
Ugh - I have one that also has a left failed speaker, which had previously crackled before giving out. A quick search on Reddit will find similar reports. Apple refuses to acknowledge the issue entirely.
My 2018 MacBook Pro arrived last week £2.6k and I turned it on to find the right speaker crackling. I now have to make a trip to Apple to get it fixed.
