I have a 2023 & it does exactly the same thing!Hello. Can anyone provide an opinion on what that whirring sound is that I hear seemingly coming from the rear brakes (or rear of car) when I depress the start button to start the ignition? The sound lasts at most for 3 to 4 seconds. I "suspect" that it has something to do with the braking system that kicks in, or releases on start-up. I don't know whether it is a new noise or one that I am aware of now that the weather is warm and my windows are open on start-up. Thank you for your input.
Hi Bob! I can look into your Bronco's noise concern on my end. To get started, could you please send a private message over with the name/location of your local Ford dealer and your Bronco's VIN?I have a 2023 & it does exactly the same thing!
