Anyone with a 2019 who is having problems with the Audio not staying on and clocks having to be reset after prolonged sitting with the vehicle off..there is finally a fix! Dont let you dealer tell you this "normal"...it isn't.

This thread might be more useful if you shared the fix

 

[Myhoopty]

Well I am not entirely sure of what the fix was...it was very technical. The point is that Infiniti has the fix now so anyone experiencing this issue should be able to get it taken care of. It had something to do with a missing fuse that went to the DCU...whatever that is.

The DCU is the Display Control Unit.

Ok thanks! I hope this post helps someone.

I have the same problem. Was it a quick fix? I wish you could share how it was solved.

 

[jadjaber]

I got my '19 car last week and I've been having the exact same problems as you described.
Can you please share details as to what was done to solve the issue?
I already took the car to the dealer yesterday and they said that they will need time to get it looked at and fixed as they have to go thru the wiring. I'm afraid of giving them the car if it's gonna take a long time (like in your case)
Grateful if you can check with the dealer and share the fix.
Much appreciated.

Apparently there was a fuse missing that ent to the DCU. I believe they bypassed something and hardwired it but I am not certain. Hopefully that info will help. If not tell your dealership to contact Infiniti of Central Arkansas Service Department and ask them!

Golly, I hope not.

They replaced the missing fuse.

Hi Myhoopty,


THANK YOU so much for your post. Do you happen to know which fuse number they replaced? It might possibly be listed on the paperwork they gave you at the end. If you can help with this I would be eternally grateful!


I am having the exact same issue and two dealerships are telling me Infiniti has no fix at this time. If I could by some chance be able to get that fuse number I can have them replace it and give it a shot, I'm sure they would be willing to try it if I had the number. AGAIN THANK YOU SO MUCH FOR YOUR POST, you rock!

 

[Myhoopty]

Sorry I am just now seeing this. I will see if I can find my paperwork.

 

[Myhoopty]

For anyone having this issue...my dealer has fixed it in mine and several after. Tell your dealership to contact them for the fix. Infiniti of Central Arkansas 844-570-2800

Fix!

MyHoopty is right. I contacted Infiniti of Central Arkansas about three weeks ago and they worked with my dealer in Ohio to help fix it.

It is such a frustrating issue to have with a new car. Basically the display unit needs to be completely rewired. Some of the 2019 models have come off the production line with a wiring flaw that causes the display unit to gradually lose power when in the car is not on. So after about 5 hours the unit loses power and everything resets just as it would if you disconnected your battery to replace it.

The issue making this complicated for dealers is that these particular cars’ wiring does NOT match the electrical schematic provided to them by Infiniti. For example, the official Infiniti schematic calls for the display unit to connect to fuse 55 in my car. Well, fuse 55 was non-existent in my car. In fact an entire yellow fuse panel was shown on the schematic and my car doesn’t even have the entire panel. So somehow the fuse panels in these particular cars are different coming out of assembly.

The good news is Infiniti of Central Arkansas had the notes on how to rewire it properly and it completely fixed my car. It involved adding a regular fuse, and in-line fuse, and a splice.

Hi:

Thanks for posting this, I also have had the same issue where the clock, A/C, and Radio settings will stop once the car is off for several hours. It's been frustrating too as I took it to one place last January and they tried to fix it twice. The clocks on the dash and the display show different times, at one point they got the dash clock to work and I just turned off the display clock but after daylight savings time, the clock is wrong. I tried fixing it by resetting the time/date on display but that broke it again, now each time I start the car, it's a different time. I will try again with a new dealership and take this info with me. Hopefully they can get it fixed now. It's less frustrating because I don't drive as much due to the pandemic but nevertheless, it needs to be fixed once and for all. Any other updates from anyone that has had this issue fixed would be greatly appreciated.

Thanks!

Have you had your front and rear battery tested? When batteries start to go bad they can make the electronics go crazy and act funny.

Ugh. Today got bad with my. Thought that system works not good, so I reset USER DATA with system hidden menu to clean / factory reset it (((
And oops. It reset the firmware and show now part no. 4DL3A as it was before 5DF2C. ((( So it reset the vehicle CAN modulator chanel... (

So what I got:

• rear camera - off (already fixed with the same menu (but parking lines disappears);
• steering audio control - off;
• the 😢😢😢 thing - any audio sources BT, USB, RADIO - doesn't work! System sound is work normal, beeping, voice command, etc... But not playing any tracks (

So any ideas how to reinstall the old firmware? I'm actually in Europe and vehicle is from USA. So official dealers here said something like - Clarion DCU is not the same and they have no firmware for it (
