Is the saving on Lego games just bad?

My son has recently started playing video games and Lego seem like the good option as he loves Marvel, Batman, Star Wars and Lego.

However, I find the saving to be very inconsistent at best. I know it auto saves, but on so many occasions we've had the auto save icon appear so we've saved and exited, only to load that save and find a chunk of progress lost.

The only games he's managed to finish are Lego DC Villains and Marvel Superheroes 2. Otherwise he just get frustrated that the auto save doesn't seem to have taken. I've watched the auto save happen only to see the game load with progress lost.
