Lexus ES Microphone Problems

Has anyone else experienced microphone issues with their Lexus ES? I have a 2015 Lexus ES with a gasoline engine, and I'm running into a frustrating hands-free problem at 174070 km. Telephony is completely dead – can't make or receive calls. The error memory is also storing a fault related to the microphone. It seems like the infotainment system might be defective. I've tried adjusting the volume, checking Bluetooth, and even speech recognition, but nothing works. I suspect it will require a microphone repair or a full infotainment system replacement, potentially costing around 815€. Before I head to the shop, has anyone had a similar experience and might have insights.

Wow, that sounds eerily familiar! I had almost the exact same problem with my old Opel Astra a few years back. Bluetooth would connect, but the microphone was totally dead. Is your speech recognition also not working?

Yes, speech recognition is also completely unresponsive. The system acts like it doesn't hear anything. Did you ever pinpoint the cause in your Astra, or did you just replace components?

I never got to the bottom of it myself. I tried a few basic things, but ultimately, I took it to a workshop. They confirmed it was an issue within the infotainment system itself. Based on your symptoms, I'd suggest a visit to the shop.

Thanks for sharing! It's helpful to know someone else has encountered something similar. I'll schedule an appointment with my mechanic to have the infotainment system diagnosed. Hopefully, it's something less drastic than a full replacement, but I'm preparing for the worst. I appreciate the input!
