Elysion microphone failure

That sounds eerily familiar! I had a similar problem with my 2016 BMW 5 series. The whole infotainment system seemed to have a hiccup. It's like when your brain momentarily freezes, and suddenly the microwave timer and the phone are battling for your attention. It turned out to be a faulty module in the iDrive system. Is the sound quality also affected, or just the microphone?

Thanks for the quick reply! Sound quality through the speakers is fine; it's purely the microphone for calls and voice commands that's dead. So, if I understand correctly, you suspect it might be a deeper infotainment system problem rather than just the microphone itself? Was your Bluetooth issue similar?

Exactly! The Bluetooth connection was wonky, too – wouldn't reliably connect, kept dropping out. The dealer thought it was a software glitch at first, tried a re-flash, but no dice. Ultimately, they replaced a module. Given your symptoms and the fact it's a hybrid, I'd say a trip to a workshop is unavoidable. They'll need to properly diagnose the infotainment system. It might be a defective module, could be a loose connection, but poking around blindly might make it worse.

Thanks for the detailed explanation and advice. I took it to the Honda dealer. As you suspected, it was a defective infotainment system, costing 815€ to fix. They replaced the unit, and everything is working perfectly again.
