Those look to be the last files in drive sessions, if they corrupt it is often as a result of a failing battery or in this case capacitor.
The camera might also be able to repair the failed files if you try and playback one of them in the camera itself, that should trigger the repair, at least that is a option on newer cameras.
You could also just take this as a excuse to update to something more current, the A119 in the V3 flavor is now a 1440p camera and one of the best bang 4 buck cameras.
Looking over your recordings now and then is a good thing to do, and it dont have to be on a week / weeks schedule, every couple of months are fine too.
When i do i look at the first and last files in drive sessions, if the first one is in a place i would set off from, and not 1/4 mile down the road from a known start point, same go for the last files in sessions, do it end in a relevant place and not just mid drive on some random road, and of course as you experience here file corruption, which most often happen on the last file in a session.
you just need to play seconds of each file you inspect, just to see if it is in a relevant location, most often home - work place - shopping place - family - hobbies, if you are like me you will find you drive the same routes over and over, and go to the same places too.
After that i take a quick glance at random files, just to see if they can play.
It take me 10 - 15 minutes on the computer with the card in the card reader to look over a 128 / 256 GB memory card this way,,,, and thats time well spent on the computer i think.
If you use parking guard it might also be a good idea to take a quick glance at those files, the order of them might differ depending on what kind of parking mode you use, motion and impact triggered are often random, where as time lapse and low bitrate recordings are constant and consecutive as regular driving files are.
Depending on your drive schedule and amount, if the memory card is 3-4 years old, it might well be a good idea to replace it, but if it is working you can keep it in the car as a backup.
These little memory cards have a finite number of read / write cycles so they do not last forever.
