Re: Resonant hum

They brought it in for service last week, moved the tires, and inspected it. Unfortunately, the technician I have been in touch with wasn't there, so I have to call on Monday to see what he found in the inspection.

It hasn't been humming since, so it was probably the issue.

Re: Passenger Safety Restraint Malfunction

I just had the exact issue. Wondering if it went away after drying?

Re: Resonant hum

UPDATE Tried to move the front to back - back to front at home and a few of the lugs are cross-threaded. I sent an online reply to a customer service survey request and I had not heard anything, so I called BMW. A technician came to my house and tried to remove the tires and could not. Now, I am sch...

Re: Resonant hum

Evanston, You may be on to something. I was over at my friend's house today, and he noticed that the tires are misplaced: the 175R19 is on the front passenger, and one of the 155R19 is on the rear on the opposite side. I just purchased this car, so I imagine somebody made a mistake at some point whe...

Re: Resonant hum

After driving using the brakes to stop (some downhill neutral braking and braking while stopping short), I do not think that it is the breaks. Unfortunately, I cannot recreate the sound. I was wondering what else is in the front of the vehicle? For example, is there a compressor that runs the active...

Re: Resonant hum

Thanks for the reply Art, these are some good points. I will try to recreate it with some braking. It definitely could be the friction break. I remember hearing a similar (but harsher) sound when I had a small rock lodged between a pad and rotor on a car a while ago; although, I rarely fill the batt...

Resonant hum

Hi guys and gals, I have a 2017 i3 (no range extender), I just bought it, and I have noticed that when I am coming to a stop without braking, there is a loud resonant humming coming from the front end of the vehicle. However, it doesn't happen every time, and sometimes it is louder (really quite lou...
