Can these code P0118, P0113 and P0741 leave me stranded and what are the meaning

The codes shown will require further diagnosis by a professional,and yes, these can indicate the possibility of a major problem.The first is for an engine coolant temperature problem--it may be as simple as flushing the antifreeze and changing the thermostat and engine coolant sensor,and the second may be a by product of that,but it needs to be checked. Your last code is for the transmission torque converter not letting overdrive occur--This may also be a simple fix--a sensor/switch. All of these may be due to regular maintenance being needed at higher mileage,but again, take it to a shop to be checked out.
