Back speakers and Sub not working.

[Nathanael]

Yes I have contacted service - just posting to see if anyone else has come across this problem.

When I picked up my Model 3, only the front speakers were working. Someone at Tesla did a hard reset, and it seemed to temporarily fix the problem. The next day same thing happened, hard reset work. Then again, and again, until now the hard reset wont even bring speakers back.

Anyone else have this problem? I picked up last week.

My boss has this problem in his Model 3. For some reason, his rear speakers only work during evenings. Tesla said he needs a new MCU but it'll take months for it to arrive. It's been nearly 4 months and it still hasn't been fixed.

Whats a "MCU"?

It appears this person had the same problem (check out video first thread post)

Any update on this issue with the rear speakers? I have this problem since I got the car 5 months ago. But doesn't look like a lose ground as that will make it intermittent all the time. Instead, this seems to be a software issue. If the rear speakers are on when you get in the car, they will stay on for the entire ride. If were off, they will stay off . All depends on the actual state when you get in the car first. Never happened to change during the driving or while the car was "on". Also couldn't find a way to turn them on when were off, even soft/hard reset not always solving the problem. Completely randomly... Anyone?! This is really frustrating... Thanks.

This is probably obvious, but did you check the balance setting in the equalizer icon?

I'm going to go check my system right now...

Working fine.

Always checking that, just to "make sure" the rear is indeed not working. Since yesterday, 5 trips with the car, 2 times the rear speakers worked and 3 times didn't...

That's a bummer- it's a lot harder to repair if it's not consistent.

Tell me about.... I went back to Tesla in Costa Mesa about a week after I got the car. When the guy checked it, of course, it worked just fine... He told me to do the reset thing and will take care of the problem. But it was not right, and since then, I was trying to figure out if there is anything possibly related to this, or causing this rather than going back to Tesla. Also I was hopping to see more people with this problem and eventually a solution here on the forum...

I had speaker problems with my 3 when I first got it. The rear speakers would cut out randomly and only return with a reboot of the center screen or if I got out and back in the car. They ended up finding a bad wiring harness in the headliner.

I was able to replicate it for the service center by striking the headliner where the hazard button is with my hand. I suggest you try this and see if it makes your speakers shut off.

Here is the part number they replaced...
ASY,HARN,HEADLINER,M3,PREM,NA,APA

Thanks ! I tried but makes no difference. Again, to me seems more like software problem. Every time, but absolutely every time, the way it is when you get in the car will stay like that until you finished your trip. Never c hanged during the trip. So doesn't look like bad connection or lose ground or something like that. Even when doing a reset (hard or soft) sometimes fixes the problem sometimes doesn't. Just randomly works or not...

Received my car on Saturday, October 27th, 2018 and by Tuesday, October 30th, 2018 I began experiencing speaker issues with my two rear speakers. It is essentially a tic toc sounds that persists through all audio playing. Just initiated contact with Tesla regarding a resolution. Will be sure to update forum as much as possible.

I just spent 20 minutes in the back seat of my car listening to just the rear speakers with balance shifted fully to the rear. Everything sounds great, so it's not happening in every car anyway.

i notice a huge difference between the front and rear speaker output. The front presentation is really great but the rears are very shallow. I have no reference point on another M3, but i don't think this is right. Anyone else experience this?

 

[IM_1406]

Stumbled on this string as there is another one with folks having rear sound system issues (flat / no sub / etc.). For me, the resets worked for a day or so before reverting back to an obvious difference when balancing front vs. rear (mush stronger in the front). Customer service said they are escalating the issue.....

Sound system lost it's "punch" after latest update

I picked up my m3 2 weeks ago, yesterday my bass and rear speakers went out just like yours, I’m taking it into SC next week to have it checked out

Did you ever figure this out? Just happened to mine yesterday. Sub is off entirely and rear speakers make a clicking sound. Front speakers work fine.

The front woofers are 8”, while the rear are 4”. So there’s your answer.
