There is a ringing noise every time I push on the gas pedal going speeds of 50 MPH or higher?

Is the radio on when you hear the noise? It sounds like you have a partially clogged catalytic converter.

Can you please shoot a quick video with your phone so I can hear the noise? That way I can tell for sure what's going on. You can upload it here with your response. We need to hear the noise, so we know which direction to go to help you fix the car. It takes time to upload so please be patient.

You can’t really hear it well but the air and radio is off. As I go faster than 60 MPH the pitch gets higher and louder.

Is this a hybrid model? Can you tell where it is coming from front or rear? Thanks for the video.

No, not a hybrid model, and it seems to be coming from the front, like almost from the radio. Also both the screens are extremely dim and I don’t know how to fix that.

Okay, it sounds like the alternator or battery needs to be replaced. This sound can come from the electrical system/alternator if one of the diodes inside the alternator has gone out or if the battery is having a problem and the alternator is overworking causing the noise. I would use a voltameter and switch it to AC voltage, then rev up the engine while the leads are connected to the battery, the voltage should stay at 0, if you get any voltage the alternator is bad.

Here is how to change the alternator in case you need it or what to see what needs to be done. Check out the images (below). Let us know how it goes.

Okay, thank you so much Ken! I will take a look at both my battery and alternator and try and figure out which one it is.

Sounds good, remember to wear gloves when working with a battery.
