Much of this rests back with the owner/driver and not the vehicle per se. Lack of checking vehicle and the carrying out of maintenance prior failure.
My first trip out with the local L/Rover club way back in 1978 and a chap had probs with clutch hydraulics in a Series 3. Master & slave cyl rubbers hadn't been replaced for umpteen years.
Similarly a trip 2 yrs ago with the local Ford Mustang Club, an engine with chronic overheat. During discussions on the roadside the owner mentioned that he knew it had been losing a small amount of water for some time.......... the water pump seal failed big time on our outing.
In the mining industry they always replace pre-failure to avoid unplanned downtime. eg, based on their own experience and manufacturers recommendation they replace a turbocharger at say 8,000 hrs regardless of whether it has failed or ok.
They plan for it, budget for it, and by doing that they hopefully avoid any surprises and costly failures as unplanned downtime is to be avoided at all costs if possible.
If you take your vehicle to remote and inaccessible areas then you should be maintaining it along the same lines as the Mining Industry does, in order to reduce the chances of inconvenience and potentially costly problems.
