So I picked up my LC500 about a month ago, and I have had this problem since the day I got it. When connected to bluetooth audio, the car will lose connection for about 5-7 seconds, reconnect, then continue playing as normal. This happens at completely random intervals with no noticeable way of reproducing. During a 4 hour car drive I had a 1.5 hour period with no disconnections, and another time where the connection was lost 3 times in 10 minutes. On average, I'd say it happens 1-2 times an hour.

I mentioned this to my dealership, but they were unable to do anything due to the difficulty in reproducing the problem reliably. Their only suggestion was that there is a problem with phone names that have non-letter characters in them. Removing the apostrophe from my phone name was of no use.

Has anyone else been experiencing this? It's a minor inconvenience, but I'd still like to fix it if possible.

 

Mine does this too. Usually after a long phone call. I recently upgraded to the CarPlay enabled system and it is still happening. I have reset phone settings and unpaired and re-paired the phone several times but still happens. Anyone find a solution to this?

 

Do you guys have this problem without car play?

 

Yes it happened before and still happening after the CarPlay update. Lexus told me it’s an Apple issue with iPhone X. Apple says it’s lexus issue. Go figure.

 

I would try to get the headunit replaced !

 

i would suggest you try resetting the entire system into default, and restarting the configuration of the phone connections again..and if you are using the USB connector make sure your Bluetooth n your phone is turned off, and also to make sure you don't have the wifi activated on the phone too.

 

Also sometimes it helps to reboot the cars computer to erase these sorts of electronic gremlins, by disconnecting the battery for 10 min or so.

 

I've had a few rare occasion system glitches with Bluetooth where the audio becomes unresponsive. Often after taking a phone call.

The head unit can be rebooted, even while driving, by pressing and holding down the power/volume **** on the center console....

That fixes it on the fly.

 

I have this same exact problem and haven’t been able to find a fix. They could not replicate it at the dealership and I’m hoping to drive it in some time once it freezes. It happens after extended 20+ minute phone calls only.

Anyone else?

 

Yes. It has happened only once. Everything but the sound works after a phone call. I stopped and restarted the car which “fixed” the problem. I like Ray & Vic’s solution.

 

I've done the same thing as VicAndRay - hold down the volume/power button to reset the system. After that, it worked fine.

 

while not ideal i've found that simply clicking the "play" icon using your track pad resumes the playback. not sure this works if BT is dropped after a phone call however

 

I’ve seen this issue before. iOS devices seem to have a lot of weird connection issues with Lexus headunits. To fix it I’ve unpaired the phone from the car, rebooted the phone, and then did a fresh pair. That fixes most issues I see with iPhones in these cars.
