What cars have the best placed known weak spots?

You know the deal, brilliant car all around, would buy 3... exceeeeeept the water pump is a known weak spot and is only replaceable by removing the entire engine and gearbox.

Or they fit a timing chain because belts are for the weak. But yeah they do sometimes randomly explode and you want to replace it before hand and well, they put it underneath the firewall, rather than at the front.

Or Or the turbo is a peach… until it eats itself. and all you have to do is just remove the front bumper, radiator, half the suspension, and the subframe, then you can almost see it.

So, what car HAS a known shitey engineered weak point, but it's actually just on the top of the engine with good accessibility?
