I was just wondering if anyone else had experienced this. My car has "suffered" from the hard throttle balloon noise since delivery. It only happened under large throttle application (80%+), so it never really bothered me. Recently, though, it's started happening nearly all the time. If I'm coasting along and slightly tweak the accelerator and I'll hear it. It looks like it happens any time the battery power is greater than 20kW, and the sound occurs even during regen >20kW. The annoying part is that it seems to come and go by day. One day it's there for any usage above 20kW, the next day it's gone. I have no idea why that might be. Has anyone else noticed something similar? I guess I need to take it in. My drivetrain clunk is getting really loud as well, so I suppose it probably needs a thorough examination.
