Weird static in the Bluetooth FM transmitter

I have a Bluetooth->FM transmitter that plugs into the cigarette lighter receptacle. In one particular car, it starts producing loud static over the music whenever the car hits a small bump. If I then remove the transmitter and plug it back in, the static is gone until the next bump or rapid turn. This happens only in one particular car, so my suspicion is something to do with electrical charge in the receptacle? Confuzzled.

Maybe the receptacle has dirty contacts or a poor solder joint that is loose.

Thank you. But since the device still works and gets power from the receptacle, merely also produces static, is that possible?

The problems is either in the plug or in the receptacle.
