The the case of the OP, quick charge likely isn't the problem. I just threw that in there for added benefit.

His problem is probably just an old/cheap cable. A USB 2.0 cable has four tiny wires, two of which are for power. And when I say tiny, I mean tiny, especially in cheaper cables. They break fairly easily. Increased resistance may make the phone think there is too low of voltage.

If you've ever had one of those cables that only seems to work when you loop it and hold it a certain way, you've experienced the broken wires inside your cable.

Better quality cables tend to have larger wires and better insulation/shielding to protect them.

Google has actually come up with a recommended USB cable list for Android Auto. There is an error message I was getting that was caused by a cheap cable, and using one from this list solved my issue. Just FYI.

My phone won't charge from the USB ports inside the center console storage compartment. They seem to be only for data use. It charges just fine from the 2 ports on the rear of the center console. As a matter of fact we can charge both mine and my wife's phone at the same time. On in each port.

The dealership told me the USB is not meant for charging, it will actually drain the phone battery. LOL So why do the refer to it as USB quick charge.

Your dealership is wrong. USB is USB. I charge my phone all the time from it. It's more likely there is a damaged cable.

Do you think the length of the cord may have anything to do with it

I don't think the length would make a significant difference for just charging, I have a dash cam that does just fine, and that cable is around 12 feet.

I have used all three methods in my truck, USB, 12v and 110 volt. My Motorola fusses if you don't use a their fast charge (12v or 110) myu not pad and several other devices including flash lights, charge just fine on the USB. My Motorola phones do as well but just complain.

I too tried to charge cell phone off the USB port below the radio head unit. Got the same "uses too much power" message. Tried several different cords; none worked. I simply charge my phone off one of the several other available ports and have no problems. The service writer at my Ford dealership indicated that the USB port below the radio head unit was for the USB stick that either the dealership or the owner would plug in for updates.
