When my engine turns back on after shutting off at a stop light sometimes the audio cuts out. "No Disc" displays on the screen then, after a few seconds of silence, the audio is back to where it was before it cut out. This doesn't happen every time but seems to be more likely to happen when the engine has been off longer.
Has anyone else experienced this?
Does anyone know what is causing this to happen?
Should I be concerned?

I haven't heard of this issue before, but I always turn off the auto stop-start. I don't want to kill the starter in our car...

The starter is rated for the constant engine stop/start use. Fears of killing it are unfounded.

I haven't listened to a CD in a car since probably 2012, so I couldn't even tell you if the CD player in my QX30 worked. For all I know, it's been dead since delivery, lol.

I haven’t used the CD player at all. I am always either streaming music from my phone or listening to the radio when this happens.

put a cd in there and leave it just for grins and see how it goes.

I have a 2017 QX30 and I just recently started having the same problem. One when the car cuts off at the light if I’m on the phone the person I’m talking to gets disconnected from the Bluetooth and I cannot reconnect them. The No Disc pops up and I have never used my CD player. Also the button button for the auto shut off doesn’t cut back on or off when pushing the button. Now when I start my car I just cut it off. I have had my car since April with only 7k miles on it and ready to give it back!!!

Mercedes electronics?

Probably to be honest. Might want to take it to the dealer under your warranty if possible.

I took my car to the dealership today. They believe it is the secondary battery that is causing the problems. Hopefully I will know more tomorrow.

This sounds exactly like what mine is doing.

Thank you so much! I drop my car on Monday I will give them the info.

 

[alexmed2002]

Not gonna lie, I didn't even know our cars had 2 batteries. Always refreshing to learn something new.

 

[Gemini53178]

Me either I’ve only had my car since April and all of this is new to me. My fiancé looked up what maybe wrong with it and he was right.

 

[Gemini53178]

I just got my car back today after 3 days and they replaced my secondary battery too! Thanks again for all of your help!

I’m glad it worked out for you as well. It is so nice to get it resolved!
