Bluetooth won't pair with phone

Bluetooth pairing failures are usually fixed by clearing the old pairing on both the phone and the car and starting fresh, rather than a hardware problem.

Symptoms

  • Phone can't find the car in its Bluetooth list
  • Car doesn't appear or times out during search
  • Previously paired phone suddenly won't reconnect
  • Pairing code doesn't match or never appears

Likely causes

  • CommonOld pairing data conflicting with new attemptA leftover, corrupted pairing record on either device can block a clean new connection.
  • CommonPhone Bluetooth not in pairing/discoverable modeSome phones need Bluetooth settings open and 'discoverable' active to be found by the car.
  • PossibleCar's Bluetooth memory fullMany systems limit the number of stored devices, blocking new pairings until one is deleted.
  • PossibleSoftware incompatibility after a phone or car updateOccasionally an OS update on either side introduces a temporary pairing bug.

What to do

  1. On your phone, go to Bluetooth settings and 'forget' or delete the car from the list if it's there.
  2. On the car's infotainment system, delete the phone from its paired devices list as well.
  3. Turn Bluetooth off and back on on both the phone and the car.
  4. Start the pairing process fresh from the car's menu, then confirm on the phone when prompted, entering any matching code shown.
  5. If the car's device list is full, delete an old or unused phone from its memory first.
  6. Restart both the phone and the car if pairing still fails, then try one more time.

When to call a pro

If pairing still fails after clearing both sides and restarting, a dealer can check for a known software update to fix Bluetooth bugs.
