I returned my third unit to Pioneer after the local repair center had it for two months last fall and a month this spring. They replaced it with the 8500 and it has no issues so far. It is critical to get in contact with them before your warranty expires.
When the outside temps are over 75F, mine would lock up. Anything under that, fine. I assume the direct sunlight and heat affect some of the units. It is a great unit, when it works.
The local shop done the update and it did not work, they would put a hair dryer on it to get it to fail.
Try talking to Nicole Johnson at Pioneer, she took care of me.
I just found this forum while searching for the same issue. Mine works as long as the outside temp is below 80 but anything higher causes the touch screen to stop working like the others. I bought my AVH-P8400BH in April 2013 and had it about a month and it worked great until the summer heat hit. Crutchfield is still making suggestions to me such as making sure the screws that hold the unit to the DIN adaptor aren't shorting out the board on the inside of the HU. After reading this, I'm inclined to get a refund since I'm still within Crutchfield's 60 day return policy.
My setup:
Not using W/R port for Steering wheel controls.
I have the phone MIC, antenna, CD-IU201S cable and USB cable plugged into the back of HU.
64 gig USB thumbdrive attached to USB cable normally plugged into the CD-IU201S cable. I do not have an Ipod or Iphone plugged in to the CD-IU201S cable.
