At most, maybe half the time I drive the car, everything seems to work normally.
A quarter of the time, CarPlay just refuses to work and constantly says CarPlay connection error even if I go into devices and try multiple times to connect to the phone.
The other quarter of the time, my profile straight up doesn't even load with my linked key. I've even seen instances where the speedometer screen says "Welcome [name]" and yet the system still doesn't load my profile when I start the car.

Is there something I'm doing wrong?

 

Hello, try the ACC Customize to OFF seems to work for me, btw there's a thread for it too https://www.clublexus.com/forums/nx-...ot-loaded.html

 

mine was off by default /shrug

 

We tend to have connection issues when we switch from my wife (primary driver) to me. Two things seem to help. Like you, we have issues connecting maybe 25% of the time.

1. Waiting 10-20 seconds in park after starting the car before putting it into drive.

2. If we start driving and it still hasn’t connected, we reboot the system by pressing and holding the power/volume **** for 3-5 seconds. The reboot only takes a few seconds and that generally clears things up. We do this even while driving.

A few times when she’s alone, my wife has had to reboot and it always seems to work.

Hopefully a software update fixes this at some point.

 

I did notice that if you go the car and start the car immediately, there are cases where the phone has not established connection to the car and it will not load the profile. Rebooting the infotainment solves the problem most of the time. For myself, the car typically connects and loads my profile 95% of the time. Maybe once a week I get the profile not loading and the reboot solves the problem. It's possible that I typically have to unplug the car before starting it and it allows the car recognize my phone.

Hope an update is coming soon, as it's almost 6 months of bug fixes should be coming....

 

Here’s my experience. If I start the car without the phone in the charger then everything loads properly. I wait until the profile is loaded and then set the phone on the charger.

If I forget and I put the phone on the charger before the profile loads then it doesn’t load.

 

Has there ever been an OTA update for this car? Seems like it could use a few updates here and there.

 

Weird...that's the exact opposite of my experience. If I leave the phone in my pocket and start the car, sometimes Bluetooth doesn't connect and things won't load. But if I place it in the tray first then everything is good to go.

 

Take your wonderful "key" and take it inside your house and find a safe "long term " place for it and leave it there IMHO.

YMMV,

I thought I'd answered this a few minutes ago saying that there's been at least one, possibly two. Then a few minutes after I thought I'd posted it my wife called and says her car is telling her it needs an update, Edit - she was wrong. There was no update.

 

We have the same problem when switching drivers, made worse by my wife's seat position, which the car seems to want me to use. Also, if the wrong profile is loaded and only one of us is in the car it often won't connect to the driver's phone.

I found it helps to leave the car locked and have the driver unlock the car when they're ready to leave.

Also, per Lexus' Tech Tip on the 'Profile not loading' you should leave/turn the ACC Customize function to on. When on, it does 2 things, your music/infotainment turn off when you turn off the car (vs. opening your door), something I like, and it also has the car looking for your phone while it is off. You can see this by looking at your Bluetooth settings and you'll see several ne BT devices with similar addresses. This is supposed to identify a profile by their phone prior to the person getting into the car. This probably doesn't help if both of you get into the car at the same time, but may help if only one is doing so. This will increase the drain on your 12V battery, which is why Lexus turns it off during shipment and dealers are supposed to turn it on during PDS.

The whole profile thing is a mess.... Anyone getting the PIN pop-up message while driving? We get it occasionally on the highway. If you're in a low network connection area and your profile times out (seems like they renew the profile validation) then you'll get the profile PIN pop-up. Makes driving, NAVng, or pretty much anything difficult. Lexus' answer is park in an area with decent cell coverage (if I had that where I lived I wouldn't get the problem) and enter your PIN.

 

There has been a lot of confusion on these boards regarding the proper setting for the ACC Customize function, but CT6978 appears to be quite right. The official Lexus tech document regarding this is quite clear: Your best chance of getting your profile to load and everything else to sync is to keep ACC Customize in the ON position and to make sure that the Link Key setting is ON. This is what has worked very well for me from the moment I picked up the vehicle. Here is that tech document:

 

Is there more documentation on what exactly ACC Customize does? Can't find anything about it in the manual.

 

I had part of my description backwards on my last post, when set to 'Off' the car looks for your phone even when the car is off. Evidently that can cause issues for some reason (beyond the battery draw, for which they turn this 'On' during shipping....on = off for some reason) so the Tech Tip suggests 'On' which seems to have helped our situation. Here's the official word from the dealer's PDS info:

'Customize ACC Function The pre-startup function detects when a user enters the vehicle and energizes the audio head unit so that the multimedia system can quickly be used. This function is not enabled at the factory to reduce parasitic current draw in transit and storage. To enable this function, it is necessary to set the ACC customization function in the navigation display to OFF.'

It also, when set to 'Off' leaves the head unit on after you shut the car off until you open the door.

 

Interesting… I’ll turn ACC Customize setting to “on” (blue) in the car as suggested in the tech tip PDF and see if it helps.
