Why is my Ford Focus's engine making a humming noise?

I've been driving my Ford Focus for a few months now and recently noticed a low humming noise coming from the engine. Any idea what could be causing this and how can I fix it?

Hi Emily, the humming noise could be caused by a few different things. It's best to take your car to a mechanic for an inspection to determine the exact cause. It could be something as simple as a loose belt or it could be a more serious issue with the engine. It's always better to be safe than sorry when it comes to car troubles.

I had a similar issue with my Ford Focus and it turned out to be a problem with the alternator. It's always a good idea to have that checked as well, just in case. It's better to catch and fix the issue early before it becomes a bigger, more expensive problem.
