2011 Highlander Intermittent problem. Radio won’t turn off and key fob stops working at the same time. Recently I noticed my key fob randomly won’t work. When it doesn’t work the radio stays on even though the car is turned off. The interior lights work as expected. I have disconnected the battery, pulled and replaced relevant fuses and reset the radio. The door switch works properly at least for the interior lights. As far as I can tell, it’s only the radio that stays on when I exit the car. I can manually lock the doors, but still the radio stays on. I have seen a couple of other reports of the same problem on the interweb but no solutions. The only thing I can think of is a relay going bad. Any suggestions? TIA
