I drive up to a local mountain town about once per week; it is a 600m climb (2000ft) over only 8km (5miles). Most of the climb is done at about 70km/hr (45mph). During the winter I started noticing the occasional "clunk" sound from the battery, seemingly under my seat, just a minute after I slowed down to enter the town. It didn't happen every time, and it was during winter, so I thought it was that frozen slush stuff falling out of the wheel well and clunking against the under side. Fast forward to this spring, and this noise still happens about 50% of the time! I haven't noticed it correlating to anything in particular yet (e.g. temperature outside, how fast I drive up the hill, etc).
I really haven't been able to figure it out and the nearest Leaf dealer is a 2-day drive over 350km (terrible infrastructure here!)
The noise is always one single clunk, and is to the point that I usually can 'feel' the sound through my seat as well as hear it. The only explanation I can come up with is rapid heating of the battery from the climb after the car has been sitting around at work all day, causing some sort of expansion.
Anyone else experience a similar phenomena? I searched the forums for clunk and found a fair amount about something to do with the drivetrain, but I don't experience this sound at the same time.
