Here we go again, we are getting reports of Bluetooth problems with vehicles and iPhones due to the iOS 11.2.6 update. We are seeing Bluetooth problems with cars including BMW, Honda, Mazda, Cadillac, Ford and GM vehicles. We suggest that if you own a car that connects to your iPhone via Bluetooth that when you get the notice for the update your iPhone ignore for now. It appears that Bluetooth audio quality is worse iPhone X models.. There are are reports of poor audio quality, loss of contacts, dropped calls, static and inability to connect completely.
Update 7/8/2018: We have compiled a new list of Bluetooth fixes to try and have more models with problems reported by our readers..
Here’s a list of some the iPhone Bluetooth problems reported

- The music is constantly interrupted when connected through the bluetooth with the car Nissan Murano Z51. iPhone 8, ios 11.2.1. The car audio software has the latest version. Previously, Z used the phone 5s with the ios 9 and everything worked fine.
- My iPhone X and wife’s iPhone 7 had been working flawlessly via Bluetooth on our Ford S-Max, until we updated to iOS11.2.1. Connecting it is mostly ok, but the audio quality is really poor, with … issue with iOS11.2.1 that will hopefully be resolved soon.
- I just bought an iPhone 6s 32 gb with Ios version is 11.2.6.

When i switch to siri mode, the voice control is working fine with all my Bluetooth devices. With my old Pphone 5, iOS 10.3.3 everything worked fine and i was very happy.

- Issues with connecting iPhone 6 via Bleutooth to my car (Audi A1’s MMI interface).
There are also Bluetooth issues reported with iOS 11.2.6 for pairing with other devices, and connections dropping.
There were problems with iOS 11.2.2 too:
- Brand new iPhone 8 with 11.2.2. Music plays fine with Bluetooth connection to 2014 Audi MMI system. However, phone calls are very fuzzy and with annoying beeps. iPhone 6 with older iOS no problems with this car. iPhone 8 connects to car no problem. I have to use speaker phone on calls in car. I assume the problem is with Apple.
- Honda 2011 Accord , 11.2 update completely detonated my my iPhone6 Bluetooth connection. Phones worked for the last 7 years with the car bluetooth until this update. It seems to have disabled my Bluetooth system entirely…..
- Formerly, we learned that iOS 11.2 is helping some BMW owners (who update their BMW software, some Honda and Subaru owners . Please read latest iOS/Bluetooth article.
The Apple Support community has been for some time time suggesting the following fix:
Check your car stereo’s user manual for how to pair with a Bluetooth device.
Go to Settings > Bluetooth, and turn off Bluetooth. Wait for 5 seconds, then turn Bluetooth back on.
Restart your iOS device.
On your iOS device, unpair your car stereo. On your car’s display, unpair your iOS device and any other devices. Restart your car and your iOS device, then pair and connect again.
Update your iOS device.
Install any firmware updates for your car stereo.
What Apple doesn’t realize is that update the iPhone could have the cause of the problem in the first place!
iOS 11.3 is going to bring major changes but we should get 11.2.6 fully working first.
The Nuke-it Fixes
These fixes remove all the settings from the car and the iPhone to start from scratch. Some have gone as far as disconnected the car battery to clear all the settings in the car, too.
1. Reset All Settings – Go to iPhone Settings ▸ General ▸ Reset ▸ Reset all settings.
2. Unpair Phone and Car Infotainment System Rename Phone – Go to iPhone Settings ▸ General ▸ About ▸ Name. Change the name of the iPhone and pair with the car infotainment system again.
3. Reset/Restore Network Settings: Restore all network settings of iOS Go to Settings ▸ General ▸ Reset (at the bottom)▸ Reset Network settings. This method also deletes all Wi-Fi and other network settings! If you reset you must re-add all your network settings in iOS.
4. Delete and Start All Over: Delete all Bluetooth devices. See full instructions.
5. Pocket or Purse Accidental Shut-off: Check to see if you shut off Bluetooth accidentally through an icon, or butt reset it by mistake.
- Disable Handoff on iPhone – launch the Settings app from your Home screen ▸Tap General. ▸Tap Handoff & Suggested Apps ▸Toggle Handoff to Off. This has worked for iPhone users with multiple devices. Handoff tends to confuse the iPhone and draw resources.
- Change Bluetooth Settings– Go to General ▸ Accessibility ▸Car Audio Routing ▸ Select “Bluetooth Headset” instead of the default Automatic.
- Change Bluetooth to Automatic Go to settings, General->Accessibility->Call Audio Routing and change to automatic.
- Factory Reset & Restore Factory reset the iPhone and re-install iOS 11 from scratch. Restore apps and more from iTunes. This cleans up all the settings and connections.
- Delete/Reset the Vehicle’s Bluetooth Settings – we have reports that by removing the fuse for the infotainment unit for a few seconds and then re-pairing the updated iPhones, it then allows the Bluetooth to work again. A variation on this fix is to disconnect the car’s battery for a few seconds to lose the stored data and then re-connect the battery and re-pair the iPhones.
Reset Delete Variation for Cars
1. Delete iPhone device profile from car.
2. Delete Bluetooth link setting from iPhone for car phone.
3. Turn Bluetooth setting to “off”
3. Go to iPhone Settings> General> Reset > select “Reset all network settings.”
5. Do a two finger “hard reset” on iPhone.
6. Boot iPhone back up.
7. Turn Bluetooth back on.
8. Re-pair iPhone to car system.
9. Test by making a call and see if it drops.
- Play with car dash buttons – just in case you turned something on or off by mistake, go through all the car’s menus and change the settings that seem appropriate. Kicking the car won’t help but may help you feel better.
- Forget device on iPhone then pair again in Airplane Mode.
- Connect through USB or AUX – for playing music you can connect with the AUX adapter or through USB to play music.
