Thought it was Mercedes that had the worst time with mechanical issues with gearbox failures and session-ending hydraulic along with car balancing.
That seems like a long list of problems they have to address with only a week left.

One part needed to be shipped from their motor warehouse in the UK. So that right there is pretty severe.
Like gearbox issue? That's nothing, they may even fix it by this weekend, or they could fix it for next race, on the other hand some issues like what Mclaren has looks to be season ending type, like they will definitely be worse this year type of thing. Which is why I am "guessing" that Mercedes will be fine and fighting in the top three by race 5 or so.
