WTF LOL!! sounds like something you'd hear about in a nulcear reactor got this message (or something to that effect) on the PCM display yesterday. Can't say i recall ever hearing about this one. Tried using the NAV and it said to instsall DVD, which of course it was installed. Used nav earlier in the day. It was brutally hot yesterday and sitting in bumper to bumper when I got this message. worked fine after i got home and car sat for a while.

 

Chris...I had it happen once to me also when my car was parked outside on a really hot day. I left PCM off until I got home - it's been flawless since.

Maybe a heat sensor went off...

 

Ive had that happen a few times when it's really hot out. It cools off and comes back on. Annoying if you dont know where you are, which pretty much happens to me all the time.

 

very strange. I have 36,000 miles on it and it's been in hot temps before. not sure why it picked yesterday to do it?
