Hi. I've recently noticed a strange sound while driving, especially when not accelerating (therefore using the electric motor): it's a low-pitched, smooth, rotating rumbling sound, very regular, near the back, possibly associated with the drive chain(?). It's not loud and there is no clanging or clunking at all. I wonder if this is normal and I just started noticing it or...? It's driving just fine. Anyone?
Also, I live in Vancouver, Canada. Anyone out there know of a good, reliable mechanic here?
Thanks,
Judy
