My Is250 F sport 2014. The same problem. Everything works except for volume control. DSP inactive. Treble, mid and bass are frozen, , front, rear left, right, are frozen as well. It is software I think. It came up after I accidentally pushed SOS button in the darkness trying to find light. To me it is class action for Lexus. I’ve read dozens of the same questions in Russian language as well. So it is kind of global problem. I paid today 170$ to a Lexus dealership for diagnostics. They said need to substitute radio. Cost to substitute radio is 2600$. I would spend 500$ for class action and they will fix it for free.
This is happening with my 2014 IS 350, however, I've paid over $3,500 on two separate occasions and the issue with the radio is still not fixed. The volume fades in and out at different levels. I'm taking it back to the dealer again, after just picking it up yesterday. This is the second AMP and fourth speaker in eight months. With 15 speakers in the car, at this rate, I only have 11 more replacements at $200/per.
I'm so frustrated...I'd participate in a Class Action.
In this environment, with the price of cars up 25%, can't even turn it in and buy a new car.
