I have carplay. Its buggy and unreliable. It locks up intermittently when you plug it in.
It is flacky if you have the audacity to plug it in at some point in the startup process of the car stereo.
Intermittently after you plug in the phone to the car the phone loses all sound making ability and you have to reboot the phone to get it back. It only does this when interacting with carplay.
Sometimes the carplay using siri won't accept voice commands (granted thats rare)

Do you have a new car with it built in or a aftermarket device?
 
If it's the head unit, then Apple needs to toughen up their standards for certifying head units for CarPlay and the car or radio manufacturer needs to fix their problems. If it is CarPlay itself, Apple needs to fix it. If it's the 3rd party apps, then the developers need to take care of business.
 
Its a pioneer unit. Ive been through two of them no change, updated firmware on the phone several times, etc.. I do think that pioneer has contributed to the bugginess and the official response from pioneer is not our problem its Apple which i thought was BS at the start. However, after careful and frequent (when it fails) consideration I believe its Apple implementation that is fragile. Pioneer doesn't help by trying to have two seperate systems running side by side. However, in the end no matter how bad the pioneer deck is (eg locking up not working properly) it should not be able to make the IPhone die. I sometimes have to reboot the iphone to get audio back at all (eg after carplay is finished with it, it no longer makes any sounds at all until a reboot). So all things being even Apple has not strengthened the protocol enough to resist a bad client device. I should also point out that colleagues have the same deck but use it with android and its faultless. So I suspect this is Apple causing the issues by being unreasonable or do not care.

I have also seen similar posts from people with manufacturers installs so its not isolated to one brand or device its all over the place.

Regarding the person whinging about my post. Don't read it. If your carplay works fine thats great im happy for you remind me to give you a gold star. Make a post, write a review thats all great. However, I have the right to report my situation especially on a story that talks about carplay winning an award. I know that when i read these comments i want to read good and bad experiences so i know what im in for.

I should also say I love the concept of carplay and when it works it works really well. Its just intermittently breaks when you plug it in. Someone mentioned they have to plug it in when the pioneer is in startup but not boot or after it starts up. I have suspected that their is a race condition happening in the deck that breaks the connection protocol as well. I suspect there are several bugs at work here due to the numerous strange ways it flakes out. However, usually when its on and connected properly it continues to work properly.

I agree that Apple needs to toughen up on their standards. Surprisingly Android Auto has more stringent requirements than Apple does with CarPlay.

I've had similar issues with my Pioneer AVIC 5000NEX head unit. As firmware updates are pushed out, I update and that seems to solve some issues for a while, but then new ones pop up. The latest issue is the head unit killing all the sound on my iPhone 6s about twice per week. The solution is to unplug my phone, shut it down, then restart. I also will get a rather loud, static growl from my speakers when I first connect to Airplay. Of course none of these things seem to happen with consistency, so trouble shooting has been tough.

There haven't been any updates for my head unit yet.
I get the same thing with the audio I can sometimes fix it by sliding up the command center and select the audio output. For some reason it goes to airplay instead of carplay. Saves a reboot.
