Subwoofers just died

Ramos · 07-14-2015, 07:55 PM

HK sound system, car is a year old, woofers have basically gone offline while driving and listening to music.

Has this happened to anyone? Anything I can check for before taking it in to the dealer?

MG 228i · 07-15-2015, 12:39 AM

Mine did this also, but the next day when I started the car it worked fine.
Never happened again...

SteveAustin · 07-15-2015, 12:14 PM

Happened to me the other day. Had to let the car sit 5 minutes off and "reboot". A little concerned and will bring it up on next dealer visit. Keep us posted on what they say.

Ramos · 07-15-2015, 02:51 PM

They came back on by themselves this morning.. Very weird, maybe a safe mode or something? I'll keep an ear out to see if it happens again

danny235 · 07-16-2015, 07:37 AM

This has happened to me twice as well. It was working fine the next time I turned on the car.

BBMWW · 07-16-2015, 08:57 AM

anyone know why this is happening?

jordantii · 07-20-2015, 11:21 PM

I had this happen twice as well. Has not happened in about 2 months.

ocN55 · 07-21-2015, 02:36 PM

This happened to me once too. Started car the next day and was fine

Same, and it's been almost a year since that time.

th1rd3y3 · 07-29-2015, 12:31 PM

Add me to the list of subs not working. They worked fine when I left work for lunch, didn't work when I got back in the car to go back to work. Hopefully come back online when I get back in since I'll be spending about 4 hours in the car tonight.

HK system as well.

nyeager · 08-13-2015, 12:10 PM

+1 have also seen this. Left it sit for about 3-5 minutes when filling up the gas tank and it started working again.

kaosHunter · 08-13-2015, 01:16 PM

I have the HK system in my 1 series and in summer, on hot days, I think the system over heats and then switches off ... I leave it for an hour or so and it works again.

Hustlin · 08-17-2015, 07:57 AM

Happened to me a few weeks ago....

Parked car and went by amp. Gave a slight push to all the connectors I could see. Started car and subs worked fine. Only has happened once in the two months I've owned the car. HK system also.

BMWZ4 · 12-16-2015, 05:21 PM

Did anything ever come of this one? My car is about 2 weeks old and it's already happened 3 times. Guess I'll check the connections before taking it in. Oddly enough, the "engine off" at idle or stop isn't working either.

simoneves · 12-16-2015, 06:37 PM

BMWZ4, see my Auto Stop/Start thread...

Thanks. Yes, read that one yesterday as well. Mine's the 8AT though. I have 2 other bmw's with this feature and works fine (not that I use it much TBH) and my 2016 235 is a replacement for my 2015 that was recalled back in Aug/Sept and it worked on that vehicle.

Bizarre. In any case, I'll be taking it in for the mystery subwoofer issue so they can look at the stop/start thing at the same time.

Ah, sorry. Hope they fix it. I doubt I'll ever really use it either but at least I know how now! :\

jonahk · 01-06-2016, 09:59 AM

I've run into a similar problem in my 2015; Sometimes the subs don't turn on, or sometimes I only get sound out of the center channel speaker.

Pulling over and turning off the car, letting it sit for 2-5 minutes and then starting back up again always resolves the issue.

I spoke to BMW about it, the dealer has looked at it, run a software update, etc. Unable to reproduce and I've been asked to drive to the dealership if and when it happens again.

What I have noticed is that it only seems to happen when I'm connecting my phone to bluetooth or connecting via USB. Remains a mystery but now that I know I can fix it by power-cycling the car (it is a giant computer, after all) it's not that huge of a deal.

2msport · 01-15-2016, 07:09 PM

Me too just now!

clarkjasonpaul · 05-19-2016, 10:37 AM

Anyone ever get a fix for this subwoofer issue? It happens about once a week for me. The dealership is looking at it but they are mostly just scratching their heads.

Jason

BMWZ4 · 05-19-2016, 08:01 PM

My dealer struggled with it for an entire day only to report back that they couldn't figure it out or recreate it.

In any case after 3 or 4 occurrences it hasn't returned and it's been many months.

sublimegolf · 05-20-2016, 03:28 AM

Same issue here too. HK as well...
