An auto throttle failure in the UK and the Asiana crash at SFO. Hard to count the Asiana crash against Boeing. A day, 12 mile visual straight in, CAVU weather is something even Asiana’s pilots should be able to handle.
If the “auto throttle failure in the UK” is the incident I’m thinking of, it was actually due to ice pellets in the fuel (they had spent a lot of time during the flight at -100F) clogging the fuel filter.

I thought the UK crash was due to ice in the fuel system. And Boeing didn’t make it out of the Asiana crash investigation unscathed:
Contributing to the accident were (1) the complexities of the autothrottle and autopilot flight director systems that were inadequately described in Boeing’s documentation...
I seem to recall that the autothrottle was unintentionally disengaged for the SFO incident. If so, I wouldn’t call that a malfunction, pilot error instead.
