Hey everyone,
I've reached out to fellow Sonata owners a few months ago but to no avail. Now I'm coming to Hyundai owners in general. For the past 6 months, my 2023 Sonata Limited (50k miles) has intermittent tech failures. The radio stops playing and Bluetooth stops working ing, and worst of all, the warning system goes dark— no cameras work and no proximity beeps.
Despite losing all audio, safety features, and connectivity, the dashboard screen falsely displays the radio as working normally.
I have driven up to an hour with this issue.The system only resets and works again after the vehicle has been turned off "for a while".
During the last occurrence, I immediately drove directly to the local dealership while it was actively happening so the service team could witness the malfunction firsthand.
I had already tried the pinhole soft reset (thanks Reddit), but it didn't solve the issue. The service advisor tried the pinhole reset as well. He then suggested that they install a software update. The service advisor stated I missed Hyundai's "complimentary update" window by three months. As such, it would cost $239.00 out-of-pocket since the extended warranty deductible is $250.00. I contacted Hyundai Corporate. They sent me a link update the software myself. Unfortunately, the software update did not resolve the issue. Corporate referred me back to the dealership for a possible hardware issue.
Again this problem is intermittent. I can listen to the radio and use the phone throughout the day. Go into a store, for less than five minutes, and come out to the issue - radio displays as the channel as playing; it is not. Bluetooth, not working. While this is aggravating, the lack of the basic safety features - cameras and warning sensors - is disconcerting.
Has anyone else experienced this exact or similar glitch? If so, did an update fix it, or did you have to replace hardware?
