I wouldn't think it would have low ABV- I think your OG reading is off. When you make an extract batch, if you use all of the ingredients and the right amount of water, the OG has to be correct. The sugars are there in the extract, already processed and they can't disappear. Inaccurate readings are common, due to incomplete mixing of the top up water and the boiled wort. That's not a problem at all- the yeast mix it up well and you'll have beer in the end.
However, if the FG is that high, the problem wouldn't be low ABV. The problem could very well be bottle bombs.
If it starts fermenting again in the bottle, the bottles will blow up causing glass shrapnel all over your house.
What's the recipe? We can figure out what your OG was, and what a reasonable FG will be for you.
