LFA Radio Antenna Issue

Experiencing radio issues with my 2012 Lexus LFA gasoline. Odometer reads 92642 km. Getting an error message on the infotainment screen and the audio system is completely dead. I scanned it, and there's an error stored related to antenna signal. I suspect a defective antenna, but I'm curious if anyone else has encountered this before I start tearing into the vehicle electronics.

Lexus LFA, nice ride! I had similar weirdness with the radio in my LFA. Seemed like the signal strength just tanked. Constant static noise. Does it seem worse in certain areas, or just all the time?

Thanks! It's pretty consistent regardless of location. Signal is just non-existent. The error message pops up almost immediately after starting the car. Did replacing the antenna fix the radio issue for you? Any tips on checking the antenna ground?

Yep, replacing the antenna sorted it right out. I didn't mess with the ground myself, to be honest. Vehicle electronics can be fickle. I'd suggest taking it to a workshop unless you really know your way around the car's wiring.

Appreciate the insight. I replaced the antenna, and that resolved the problem. Repair cost including the new antenna was 255€. Thanks again for confirming the likely cause. Saved me a lot of time troubleshooting!
