Hey people! I have a 2019 ram rebel with the 8.4 head unit. My CarPlay connection randomly stops working. It WAS working and it stopped. I grabbed a new genuine apple cable and it worked..so I figured the cable was bad. Couple hours later I’m having the same issue. Tried another cable..and the same thing happened again. My phone will charge, but the CarPlay app doesn’t populate. I also get ‘USB error’. Super frustrating. CarPlay works fine with My VW tiguan. iPhone software all updated etc. seems to be an issue on the trucks end. Anyone have a similar issue??

This just alleged happened with mine! One day I heard a crackle sound coming from the stereo and now Apple CarPlay doesn’t work. Tried a new cable and iPhone, still no luck. I’m about to call the dealership.

So I talked to my service guy at the dealership today. They are having lots of issues with Uconnect. My wifes Pacifica is acting up like that. Knock on wood my Charger has been fine.
I had a similar issue and mine turned out to be the cable. I had Anker M-Fi certified cables (not much cheaper than Apple cables) and my truck seems to only like the real deal Apple cables for CarPlay.
I know you've tried an authentic Apple cable but have you tried any other USB ports? I'm not sure if you have the 5-seat or 6-seat option (center console or bench in the front) but I have the center console and 3 of the 4 "channels" are active for input signal (e.g. CarPlay). The two in the dash and the driver's side rear USB channels. The passenger's side rear is a charge-only channel. Each channel has 2 ports - a USB-A connection and USB-C connection. I'm not sure if the bench seat trucks have any rear USB ports but I would definitely try all 4 in the dash to see if the problem follows or is specific to a port.
If it's not a hardware issue (wires, connector, USB port/hub) you can try to 'soft reset' to see if it clears the issue. This was recently posted on another forum by RAMCares:
1. Put your vehicle into the accessories mode (ACC or RUN) **For keyless start (push-button) vehicles: push the start button twice without having your foot on the gas or brake pedal**
2. Hold down the Phone and voice recognition buttons (or tuner and volume knob), at the same time, for thirty seconds.
3. Let go of the buttons
4. Turn the vehicle off
5. Open driver’s side door for thirty seconds (or until dash illumination goes black)
6. Close door
7. Restart vehicle
8. Let the media center load up and see if the concern is still present
Hopefully that helps.

My Carplay 8.4 has been doing this in my 2019 Ram as well for a few years. My specific issue is when my iPhone battery gets to a full charge, then the Carplay disconnects and seems to reset. A second or two later, it reconnects on its own. If I'm using Google Maps or Spotify, I will have to restart my destination on the map, or my song on spotify. I've had 4 iPhones, including brand new apple wires and it does the exact same thing, regardless of the phone. And, I rent a ton of cars for business travel and have never had the issue.
I've asked the dealership to troubleshoot, but of course they say they've never heard of this issue and can't duplicate it to repair it.
Has anyone experienced this issue with the battery coming to a full charge? Any suggestions?

Uconnect told me there is a dealer only update for the carplay issue. Took to dealership for update. Carplay worked.

I had this issue and just resolved it. My USB would charge but not work with a USB stick or any phone cable combo I tried. I hard reset the radio. I pulled the fuses to the radio and USB hub. I disconnected the battery for a while. Nothing worked.
I just unbolted the center console and slid it back... unplugged the USB hub connectors (they were clipped in fine by the way!) and reconnected them. Plugged my USB cord into my phone and bam, CarPlay again. No idea why this worked and killing all power didnt, but it worked. Takes about 10 minutes. Worth a try...

Do you know what they did or what update?

I will try to find out for you. I called Uconnect and gave them the vin and asked for firmware updates. They contacted dealer and they took care of it. My Jeep is in with weird issues. The nav says 1.2 miles and turn right. The dash says turn right in 4029 mi. They are trying to figure it out now.
