I have a 2020 Toyota Camry XSE. Ever since the iOS 18 and 18.1 updates while connected to my car via the USB cable to CarPlay when receiving or making calls the calls are lagging. A little bit of background is I have the new iPhone 16 Pro, the phone is completely up to date and my car has all the latest updates available as well so everything is up to date. I also bought a new USB cord to make sure it was not a cord issue. When I connect to my car through the cable and go to car play, everything works except for when I make or receive a call. When making or receiving a call upon answering or starting the call the moment the person picks up the system delays both voices on the call. What happens is the "time on phone display" that shows during the call, the time does not move like the call is frozen on the screen. Because of that the call is lagged when I speak or they speak and you are unable to have a normal conversation because of this. If I put the phone on speaker while still connected all of a sudden the call time unfreezes on the screen and starts counting again but the moment it take it off speaker the time freezes again and the call starts lagging again. I have NEVER had an issue until the iOS 18 updates. Please provide any feedback or suggestions, or if this is a known issue and it is currently being worked on. Like I said everything else works except for making/receiving calls that is when the issues start and the CarPlay screen freezes and starts the issues.

GUYS! Kyyy found the fix! I was in the exact same boat as all of you. I was about to bring my yota in for a firmware update for $170. Went to google if the firmware update would actually fix my issue and found this thread / kyyy’s post. Followed her and the websites instructions and boom! Problem is gone! This issue started when I switched to iOS 18 as well. The website is https://www.toyota.com/firmware-updates The only hick up I ran into is when I first downloaded the file onto the flash drive my yota did not see the update. I then used disk utility on my mac, found the drive, clicked “erase”, the erased each of the “formats” listed. Once completed I redownloaded the file onto the flash drive and then my yota was able to recognize the update!
If yall run into an issues, let me know and I can try to help you out. Im so happy! 8 months of frustrations are over!
