I have an 02 Forester S, 29M miles, stock battery. THis past week we had a cold snap with temps below zero. The car refused to start with any sub-zero temps. I ended up putting a heating pad on the battery through the night and that seemed to give it enough help to start the car but just barely. With warmer temps the battery seems to have enuf juice to crank.
So, I took it to Goodyear yesterday and had them check the battery and they tell me that its weak, only pulling 8 something volts under load. They said it should be well over 9? I called the Subaru dealer here in Spokane and they said the battery was covered under warranty. So I take it to them today. They checked and said the battery was fine. I asked them if it should crank the car at sub-zero temps and they said yes. I told them it didn't. They just smiled and reiterated the battery checked out. I guess I will just get a new battery but I felt like the dealer was jerking me around. Is it normal to have the car refuse to start at anything below zero?
