Apple Carplay stopped working Accord 2018

I have the same issue with my 2018 Accord. The manual and Honda Tech Tutor web site says to connect phone before starting the car. I did a factory reset thru the car display and it seems to have worked. But first I deleted my phone so I could start all over. But I have to start the car first and then plug phone in.

This is what I did and it seems to be working. (2018 Accord). Delete phone from car. Go to settings, and choose Factory Data Reset. Start cat if it is not already running, then plug phone in. The Honda manual says to plug phone if first, then start car but I found that I have to start car first.

I've had my car a little over a week and it stopped working. The only way to connect my phone is via Bluetooth. I have an iPhone 7 plus the software is up to date. Yesterday I did a system reset back to factory 4 times which was useless because all the presets are still in the unit so nothing changes. There seems to be little information out on the issue. I also noticed the USB ports do not charge the phone. So it might be a defect in the equipment not yet discovered. My cables are new apple cables so it's not that.

Try doing a factory data reset thru the car’s display. It worked for me. But I have to start the car first then plug phone in, which is the opposite of what the manual says. Also here is the Honda Tech Support # 888 528 7876.

I talked to Honda Tech support did not find it troubling at all that the factory reset didn't clear anything in the vehicle. Even when I told her I had done it several times already she insisted that although it was odd it was not the problem. I was referred back to the dealership after we tried 2 more times to reset the vehicle. I guess I'm off to the dealership this weekend. The rep said since the USB ports aren't charging that must be the problem. But yet I connected a flash drive and it picked it up just fine.

Have you tried deleting the phone from your Honda's Smartphone settings and the Honda from the CarPlay settings? I've done that after some updates and noticed it worked for me. I have a 2016 Civic with CarPlay and have had some issues with CarPlay not even showing up. I usually see the black screen and a notice of nothing connected or that CarPlay couldn't start and to try again when I've stopped my car to retry plugging my phone in. My local dealer stated that each time Apple does an update to the OS I should be deleting the profile from both and allowing it to reset up as new after updates. Usually just deleting the profile from the Honda is all I was told I needed to do but in some cases I've deleted both and saw improvements. Honda recently told me newer phones from Apple and Android makers are not compatible but I've seen better CarPlay experience using my X than my 6.

Adding to this thread so this problem is hopefully resolved soon. I have an iPhone 7 plus running iOS 11.2.1. CarPlay has been working fine since I got the car roughly a month ago. But now I get the dreaded 'cannot start carplay' error whenever the cable is plugged in. I have tried both having it plugged in before starting the car and after, and connecting manually through settings, nothing works.

Stopped working after 4 months in my 2017 Civic Hatchback EX-L. The last couple days it worked on and off so I thought it was the cable. Today driving home from work it didn’t work at all. I have an iPhone 7 running 11.2.5

My new Accord has experienced the same issue. CarPlay works then the next time I drive it doesn't and my iPhone is not recognized. I called Honda Tech's 888 number and it is a known issue that they say is only two days old. They are working on a fix. They have issued a Techline Report so dealer service centers should be aware of it.

I was STRONGLY advised NOT to do a factory reset of the entertainment system

I will try to report back when I get my fix - for now I have to use BlueTooth and forgo Maps.

I have the iPhone 6S fully updated and running 11.2.5.

I have the same iPhone 6S and the same issues. My radio even reboots itself while I'm going down the road listening to music or just talking on the phone using CarPlay. Unfortunately I did the factory reset a few times. So hopefully that firmware/software fix Honda is working on comes out soon!

My Honda Accord EX-L 2018 has problem with smartphone connection. That is very wired. I don't know why. Smartphone connection with apple CarPlay. It has sometime problem but I tried put factory restart on the system. That is always again. :/

Bought a 2018 Accord Touring today. Same issue and error message when trying to connect to CarPlay for the first time. Surprised because I thought Honda has supported CarPlay for several years. I'll try the battery method or the reset method and see what happens. Crap.

Since it appears this is a Honda issue we'd be better served if everyone complained to Honda rather than doing a DIY fix with via reset or battery disconnect without letting Honda know about it. I went to owners.honda.com, went to link "open a ticket" and sent them a recap of the CarPlay issue. I attached the .jpg with the Honda Tech Line article about the problem. Just want them to be aware that many are having a problem and they need to create some urgency about a fix. I'll post any response from Honda here.

I just had a similar problem. A little background: my Car Play has been intermittently buggy. It often loses its connection and I have to unplug and plug in my cable-- but it usually comes back.

At the same time, the entertainment system occasionally goes out, or gets stuck in "private call" (does anyone know what that is?).

One day, it got stuck in private call mode and then everything went black. Turning the car off and on did not help. After an hour off, the screen came back and bluetooth, garmin maps-- but not apple car play.

I tried a "factory reset" in systems and that seems to work. But for how long??

Anyone have similar problems? Is this this a Honda problem or apple issue?
