Thanks to everyone that contributed to this discussion. Earlier in April my 2010 FFH started to "chime", it was so quick and random that I could not even come close to making a determination as to the cause. A quick search on the internet led me to this discussion. The symptoms described here fit my situation exactly. Last Friday I called my dealer, explained the situation and sent the string of discussions. They didn't want to order the part without seeing/hearing the car first, however a part was in the area. They hadn't heard of this problem before, I never like to be the first in this type of situation. They wanted to perform a diagnosis first, $170, I told them they could but if it didn't show something other than what I described as the problem I was not paying for that - they agreed. They didn't find anything on Monday but wanted to drive it, so it was there on Tuesday. I again reminded them that chances were slim it would be recreated. In my case it only chimed when outside temperatures were over 70, but still rarely. Tuesday results were the same, just as I predicted no chime. They ask if I still wanted to have the part replaced anyway - of course I did. So now we are to Wednesday. They replace the part, only to have the Check Engine light come on, so more testing. There was a bare wire "upstream" from the targeted cause. Four days later my car is fixed. They want me to check back in, in the event it is fixed so they can note this in their files since it was a first. Also they mentioned that the antifreeze listed above was the wrong type. Thanks for the help, should have made this a quicker fix, but I guess they got some training too.
