Hello Everyone!

I've been struggling with my dealer for a couple of months on this issue. I use auto stop start from time, call me crazy. Anyway, when I'm sitting at a traffic light and car is off... and I engage the clutch to start the car, whatever I am listening to on the audio system silences for 2-3 seconds and then comes back on.

The head tech has been in contact with Ford HQ but so far they haven't provided a solution. Last thing I had to do was prove that I had done no modifications (I haven't) and that it doesn't happen in other RS's (that was a heap of fun).

Has anyone else had this issue?

My car has Sync 2 and was built in July or August I believe.

Haven't experienced this myself, as I turn off the auto s/s robotically now.

Does it happen only with certain sources? (i.e. streaming over bluetooth from your phone might need an extra few seconds to reconnect if the receiver end is removed.

I use the auto stop/start feature and this does not happen with my car. Have also not ever used standard AM/FM radio... just Sirius and music on a jump drive.

There should not been an issue. When I'm using XM, FM, CD, BT or AA the music just plays during the restart. My first guess would be that there is a bad connection somewhere allowing the voltage to the radio to drop too low . Just a guess though. If I were trouble shooting I was start with a system I could log the voltage when auto stop/start is working on your car and one that is not exhibiting the problem. If no difference look for something else, if there is a difference find the cause.

Whoa, they made you prove that other RS's don't do this. That's as bogus as it gets, the sell the damn things, and can contact Ford. Unless they are a cheap "We sell everything" type garage.

Also, I can't believe you had to prove you don't have mods. They need to show you do have mods and they caused the problem. Deciding it's your fault up front means I go to another Dealer right off. Lets not forget who the customer is, and who is paying 36000+ to Ford for the pleasure.

All that said, I can confirm other RS's do not display this behaviour.

Any resolution to this? Mine just started doing it today. Got in the car, started it, and could smell a slight hint of burning electronics. And this is the result. Music gets shut off after restart.

Check that your battery terminals are securely tightened on the posts, and that there is no corrosion on the ground cable connection to the chassis. Nine times out of ten, brownout issues are due to bad grounds or loose battery connections. I use auto start/stop and so far haven't noticed any radio shutdowns.

Hey guys.. I have a new 2017 RS2 and the music (whichever I'm using, Bluetooth, radio, android auto), always shuts off for a second or two when car starts back up when engine auto-stop is being used. It sounds like it was a faulty BCM?

So my car has been in four times now and it's not fixed. The music still cuts off right as the engine restarts from auto stop. The dealership says there's something wrong with wiring and Ford "hot line" is telling the dealership it'll take a week to come up, and send, the wiring diagram. This problem has been since I rolled off the lot. Anyone else fine a definitive cause of this???

It sounds like the voltage is dropping too low from the starter motor draw. This will be expensive to troubleshoot but i bet a larger capacity battery will fix the problem... For reference i do not think my radio cuts out when auto start stop restarts the car.

Thanks.. I guess they put in a new battery but no fix. What I don't get is that there's no available schematic layout of the wiring, which is supposed to be available.

What are you talking about, no schematic layout of the wiring? They can get it, I have the hard copy and its on the FSM disc.

Ih, interesting. The dealership said that Ford "hot line" says it'll take up to 2 weeks to send it.

Update: I've been to the dealership now 5 times and no fix. Ford is telling me there's "three known RSs with this problem." They tell me Ford is investigating this. Meanwhile, I realize that there's some wrong wiring, which is unsettling. If they can't fix this, I wonder if this is cause enough for lemon law claim. I got the car brand new and it was like this off the lot. I won't tolerate a bad wiring issue to not be fixed properly.

Depends on your state and time/milage with the car.

Update: It's been months and STILL no fix. Dealership says stuff like "still waiting for Ford to let us know next step." Now, I have a bad engine mount...vibrates awful at idle when AC is on and they're telling me, "can't find a part" so, this apparently can't be fixed either. WT#... I think I'm ready to either do a buy back or activate lemon law. I really like this car but if things can't be fixed, maybe should pursue lemon. I've only 6K on it.

Try a different dealer? Where are you at?

Sounds like their electrician isn't up to the task. I'm half curious if it's just a connector or grounding point that needs cleaning.

Is it throwing any codes or have any pending codes? That could point to an issue too.

Exeter, New Hampshire. The master tech is good. It's not throwing any codes (they tell me). They can easily reproduce it but they're not doing anything Ford corporate isn't saying to do...they won't.

I must be one of the 3. Its been doing this for well over a year for me now also. As a matter of fact, just for fun, I think I will give the dealer a call. In all fairness, they have been good about it. Pretty much every piece of electronic components have been replaced. Head Unit, BCM, PCM, even my steering wheel. All to no avail.
