Apple CarPlay keeps disconnecting (2021)

Can anyone check if the disconnection happens when you are passing near a cellphone antenna??

I’m pretty sure that the reason is related to this.

In different places when the phone begans to fail I look around and an antenna is near.

I have had wireless CarPlay disconnect in the same area numerous times. No cell tower that I can see but I can see several communication attennas on top of a high structure that I have suspected may be the issue. I have a 2021 Hyundai Santa Fe that only supports wireless CarPlay. I have a iPhone 12 and have tried an android phone and have no problems with it.

Apple feels the issue is with the Hyundai Wi-Fi connection and Hyundai feels it is just a dead spot.

I feel it is Hyundai problem as different people have indicated no problem have been experienced with a wired iPhone .

Not sure if they are cellphone or communication antennas, but they are always present when disruption happens.

Clearly is not a hyundai issue.

I have a Pioneer unit that supports wireless carplay and android auto and the only problem is with the iphone.

Seems tha Apple can’t find a solution and blame others for their fault.

They have to start figuring out what might be the problem cause in a near future all cars would have this technology

Thanks for your comments. Apple feel it may be a problem with the router in my Santa Fe and asked to see if I can find out if the vehicle has a single band or a dual band router which apparently is what is used in most homes to help stop interference. They have also asked me to find someone with another make of vehicle to see if I experience the same issues with CarPlay.

They have assigned me a specific agent to work with me.

Local Hyundai dealer insist that the area I have the problems is a “dead zone” and the same thing happens with android phones. After their comments I hooked up a Samsung android wired connection a had no problems.

Will provide more comments as I have more information

with your pioneer unit can you use wireless android or is it a wired connection

That’s not the solution.

Why do I have to use wired CarPlay when is supposed to work wireless.

And the problem is not only with Hyundai cars; is with the wirelles connection between the iphone and the unit.

I have this same disconnection issue. Have had many calls with Apple without any solution. There latest request was for me to contact the local Hyundai deal to find out if the router was a single or dual band. It may disconnection is caused by wireless interference and if the vehicle only has a single band router then it is not “robust “ enough to stop interference. I have no idea about this and doubt if I will get a response from Hyundai. I think most routers for in home use are not single band

2021 Mustang Mach-e/Minneapolis/iPhone 12Pro

This happens to me as well (and has since I got the car) at specific points in downtown Minneapolis, and it happens in North/Northeast Minneapolis whenever I drive near shot spotters.

Is there a fix for this?

What I have found so far is my phone and daughters phone, both iPhone XR, constantly lose connection. So much that you can’t even use Apple CarPlay. If you use just blue tooth it works fine. But that doesn’t help with GPS navigation. My wife’s phone, iPhone 11, seems to have no issues with Apple CarPlay.

The YouTube video for engineering mode works. Everyone with this issue, should, for now, do this. It will save you tons of aggravation when driving. You could also switch it back whenever you want.

It is very frustrating to scour the internet and see all of the people who have 2021-2022 cars and trucks from different makes and models all having the same issue with the wireless CarPlay dropping and Apple not taking ownership. It’s clearly not a manufacturer problem. And one thing that is definitely up to Apple is the refusal to allow plugged CarPlay in a Wi-Fi enabled car. We have a 2022 Elantra and it supports Android as Wi-Fi or plugged but CarPlay is only by Wi-Fi and it’s awful. Nothing like losing your maps while driving. How dangerous!!

I am only speaking for myself, I would not want to give any advice. I know its frustrating, It was driving me crazy. Same issue, map cutting out constantly and having to re-put in directions, just for it to drop out again. Sometimes it would not come back at all. There is a YouTube link; other people have posted it as well. Although I will lose wireless Apple Carplay, I will at least have confidence knowing my stereo will not drop out, and I can start to enjoy my new car again. It does not appear that there will be a fix anytime soon, I am using this fix until they finally have that recall for the stereo or wifi antenna. In the mean time, I have a working stereo. Also I can always switch the stereo mode back to wireless whenever I want. I have been running this for over 2 weeks now with no problems. Please note, in the video he changes it to version 4, but most people are having success by using CPU version 1.

I also experienced this issue. 2-4 times per day. I have a 2019 Audi etron. I experience a CarPlay disconnect/reset at two particular areas of my commute. I have experienced the issue with an iPhone 8s and a new iPhone 13.

I have experienced the disconnect with Bluetooth, but also when the phone is plugged in via USB and Bluetooth is disabled.

no one seems to have an answer to this issue. I have a 2021 Santa Fe that has support only wireless Carplay and I have constant disconnections at one location, In my case the Iphone loses the wifi connection with the car and the map screen goes blank with a message the the phone is not responding. Eventually the wifi will reconnect but the phone projection to the car will continues to be blank, I have spent hours on the phone with apple only to get more frustrated.

All Hyundai are saying that I must be driving through a dead spot and that is causing the problem. They could offer to answer as to why the phone did not reconnect etc.

I feel that there is a problem with the wifi router in the vehicle but no one even wants to talk about that.

As in my case my Santa Fe only operates with a wireless carplay or a wired android connection. The wired android works fine and a wired carplay in a Nissan Kicks also works without any issues in the "so called " dead spot.

I feel it is a Hyundai wifi issue but no one seems to even want to address the issue.

When I buy my next car this will be one thing that will be checked as this issue will be a deal breaker

Yep that is the exact same thing that is happening to us with the 22 Elantra. Nobody has any answers Hyundai they just keep making excuses so I figure Apple Hass to figure it out. It’s multiple cars and all Apple devices so it probably is related to Apple not related to the car. But either way Apple has a bunch of insanely super smart people working for them so I’m sure they can figure it out

This issue has been ongoing since the onset of the wireless carplay. It does not seem to be resolving itself anytime soon. I wont make any recommendations as to what to do with your stereo, but following the video that is posted above worked perfectly for me. I no longer have wireless car play, but wired carplay works perfectly. I can always turn wireless back on if they ever fix the problem. CPU config 1 is the option that seems to be working for everyone.
