Mazda 6 - 6th Gear Issue

[THP150]

The wife has a 2013 6 2.2 175bhp diesel, which has developed a fault that 6th gear pops out. Car is a company car and regularly serviced, it has now done 62K miles of travelling up and down from Kent to Newcastle.

She will have to travel done from there today and funnily enough the car was due to go in for a service tomorrow.

Has anybody else heard of the new 6's with gearbox issues?
