I have a problem that I’ve heard twice on Car Talk. One call they had no answer, the next time they had the same obscure answer I have for my car, so I feel in good company, but alas I have no solution for my car (2000 Subaru Legacy Outback 4 door, white).
Two years ago we drove from NW Arkansas to east Texas in the hot summer. After a few hours we made a pit stop. Came out and car was dead, no click, no nothing. Opened hood and waited a few minutes and the car started. This exact sequence of events happened twice the following summer and once to me this year. The first time we had the battery checked and it was OK. It’s never happened when traveling in moderate or cold weather.
My inkling is that something that should be closed (electricly) is open from the heat. When it cools enough it closes and the car starts. It only takes a few minutes with the hood open.
The dealership says they can’t (duplicate it or) fix it when it’s working and I can’t let them take off for a road trip just to diagnose.
Does anyone know of any common things to look for that might cause this problem? I was thinking of taking a heat gun to different components if I knew what to try. Can a battery test good and act like this under extreme hot conditions?
Thanks in advance!
