Bluetooth Connectivity Issue: iPhone 16 (iOS 18) and 2022 Toyota RAV4 Hybrid

Infotainment system is fully updated. I suppose it could be a Toyota update issue. However, interestingly, my wife has a 2021 Toyota Highlander and has no issues. I assume it would be the same software update. She also upgraded to an iPhone 16 and it has BT connections issues with my car (RAV4). So, I know it's not just my phone. Frustrating.

If CarPlay doesn't detect your iPhone, make sure CarPlay isn't restricted. Go to Settings > Screen Time > Content & Privacy Restrictions. If Content & Privacy Restrictions are turned on, tap Allowed Apps and make sure CarPlay is enabled. Go to Settings > General > CarPlay, tap your car, and then tap Forget This Car.

If you're still having trouble with your car's audio system using CarPlay or Bluetooth, try the Aux cable. To get it fixed, there are two options:

1. Take your car to a reputable car dealer or car audio specialist. They have experienced technicians who can diagnose the problem with the Aux cable. This could be a loose connection, a faulty cable itself, or an issue with the system's Aux port. They'll be able to repair the issue or recommend a replacement cable if needed.
2. Consult your car's infotainment system manuals. These manuals often include troubleshooting sections that might address common Aux cable problems. You might find instructions for resetting the system, cleaning the Aux port, or confirming the cable's compatibility.

Before taking your car to a dealer, it's always a good idea to check the manuals first. This can sometimes save you time and money if it's a simple fix you can handle yourself. However, if the manuals don't offer a solution, or you're uncomfortable tinkering with the system, then a car audio specialist is the way to go.

Refer to the list of cars that are compatible with CarPlay --> iOS - CarPlay - Available Models

I understand it being frustrating, however as I said earlier, the reports that I've seen have been restricted to RAV4 Hybrids. It would seem there is something specific to that particular model. There are other posts about that vehicle here in the forum.

Have you tried to connect your phone to her vehicle? Does it work with her vehicle. My guess would be yes, since her iPhone 16 works in her car but not yours.

So it is possible that your Toyota needs an update to the infotainment system. It is up to the vehicle manufacturer to be sure that their systems work with Bluetooth devices, not the other way around. Newer devices can have newer versions of software that manufacturers need to ensure their devices will work with. When you see a number of issues with a single version of vehicle, it is usually the vehicle's fault.

So once again, thank you Apple and Toyota for prioritizing road safety so well that I have to keep rebooting my phone to make a hands-free call.

Apple is not going to see this here. This is a user to user support forum and Apple does not participate here. The only thing I could suggest now is to reach out to Apple Support. We have 3 iPhone 16 models in the family and none have experienced any Bluetooth issues with the latest iOS 18.4.1 installed. They can run diagnostics on your device and see if there is an issue with Bluetooth.

Here is information for contacting Apple Support, thanks to fellow ASC member Lawrence Finch.

Best way: 

• Install the Apple Support app on your iPhone or iPad - you can contact support directly from the app, and the tech will have (with your permission) access to diagnostic data on your device

Other options:

• • Click on “Support” at the top or bottom of this page
  • Go to Contact Official Apple Support

(Note that both of the above have options to receive a callback or chat)

• • Call Apple Support; the phone numbers are in this link→Contact Apple for support and service - Apple Support
  • Make a Genius Bar appointment at an Apple Store→Genius Bar Reservation and Apple Support Options - Apple
  • Find an Apple store or Apple partner service provider→Find Locations

Yep. My phone (and hers ... both iPhone 16's) works fine in her car (2021 Highlander). And, both phones don't (connect/disconnect intermittently) in my car (RAV4). Driving me crazy.

same for me with my 2021 RAV4. The iPhone 16 works fine with my 2015 golf. It definitely has to be a Toyota issue.

I have had this exact same problem. We had no issues with our previous iphone 15. It connected fine via bluetooth, and was used regularly. As soon as we upgraded to the iPhone 16 this problem began. It happens with both of the new iphone 16s. Cycling constantly between connected and not connected. The only work around we've been able to succeed with is plugging in via USB for car play. Then everything works fine. The only changes in the situation was upgrading the phone model and IOS version since the iPhone 15 / iOS 17 combo worked.

Yep, I've got the same issue (iPhone 16, RAV4 Limited). Also have done all the standard stuff (i.e. "fixes"). After researching, this appears to be a VERY widespread issue. The hope is that an iOS update will fix it. Otherwise, if it's a iPhone hardware issue ... we're screwed.

I have seen, and participated in other threads where the OPs have reported issues with Toyota RAV4 Hybrid vehicles and Bluetooth. There they reported it had been reported to Toyota. If the iPhone connects to other Bluetooth devices, and they reported using a Bluetooth dongle and it working fine, it is an issue for Toyota to fix.

Yes (my iPhone 16 to her Toyota Highlander). Works fine.

Update: Applied iOS 18.5 today (5/12/25). Unfortunately, even with indications from Apple that these Bluetooth issues will be “fixed” with this update … no change. Honestly, I wish I never “upgraded”. iPhone 13 perfectly stable. iPhone 16 bluetooth is garbage.

In my particular case, no issues with Bluetooth and my RAV4 Limited ... until I got an iPhone 16.
