I bought a Bravo not too long ago, pretty flawless with a good service history. The only issue I could find with it is a strange running sound, almost like the sound from an electric motor (unless my Bravo is an ultra rare all-electric Bravo that takes petrol anyway 
).
The sound seems only linked to the actual speed of the car (i.e wheel speed), and not engine speed, engine load or gear. The testing process I went through is putting full accelerator down at low RPM in all gears to mid RPM and the gear stick doesn't vibrate at all and there are no other strange vibrations. The steering wheel doesn't vibrate at all and everything else seems fine. I've tried coasting in neutral at high speed and the sound persists, and also changing up and down gears but again there is no change in the sound pitch or volume at all and it still persists.
It starts to become noticeable around 30mph+ and gets louder with wheel speed, and sounds like it's coming from behind the dash/glovebox area. I've also tried slaloming (in a safe area at relatively low speeds for those safety conscious of you ) and that doesn't seem to effect anything so I'm guess it isn't wheel bearings (although I've definitely been wrong before!).
I've linked a sound clip below where I accelerate up to around 50-60mph, and change gears from 6th to 4th and back again regularly as well as coasting to show no difference in sound. Around half way the sound does change slightly but I can only assume this was because I must've slowed down a slight bit.
Lastly the audio was very very noisy and bassy so I've applied a high pass filter in case it sounds a bit tinny, but it really emphasises the noise. It's louder in real life and very noticeable at these speeds.

Importantly I'd like to get this diagnosed and sorted sooner rather than later as I don't want problems to develop down the line and I've also got warranty on the car at the moment if it's anything serious. I'll be taking it into a garage around Wednesday to be diagnosed and hopefully fixed before a 4 hour round trip on Saturday down the country.
