It all started with the Radio volume control spontaneously turning itself up. The console touch panel volume control would light up and volume increase a few seconds later. Diagnosis, panel defective and waited three months for replacement to arrive ($1,100). After installation/replacement, front radio speakers would not come on until car driven for a few minutes but then OK. Next, the A/C began to turn off, turn itself up/down and lock up on its own. Diagnosis, newly replaced panel was defective so ordered a new one. Available quickly and installed. After installation, radio front speakers quit entirely. Diagnosis, radio amplifier defective and must be replaced ($900). awaiting repair and return. Hope this is the end but have my doubts.
