Well I presented the problem of this automatic volume control on the 2023 Corolla 2.0 gasoline engine (USA market) XSE HB with JBL sound system which is suppose to be able to adjust volume by speed of vehicle by choice.
On Friday, Dec. 1 A sales person adjusted it the same way as I did prior to this Toyota 24 Mo. free maintenance check I came in for. Afterwards the volume still doesn't adjust or change at all in the settings level per speed of the car.
From what we both see is that there is only on button that you engage to get the auto volume and it is lit up to engage.
Now Toyota Service wants to look into this further. They were not sure during the 24 Mo. Toyota free maintenance check which is a "do it while you wait" for customer and said they would need more time to analyze this so I would have to leave the car with them at another time and date.

🥺
This is the same dealership that put my tires at 38 PSI 😱on all 4 tires for the 24 Mo. Toyota free maintenace check which per driver side label calls for 33 PSI front and 30 PSI rear which I changed the air pressures back to during the evening when it is at its coldest temperature.
I would hate to leave the car with them especially if they create a new problem by going into this further by opening up the system.
I wonder if there is a TSB on this informant / JBL Stereo system level adjustment auto volume speed adjustment??
The service representative called me today and asked me if I wanted to schedule an appointment for this problem. He told me he does not know what is involved and be prepared to leave the car longer than a while you wait service.
I don't want my car to be a guinea pig test case since they don't seem to know about these cars with all of these fancy features and too many different models they cannot keep up with i.e. L, LE, SE, XSE, hybrid, etc.
