Hi All,
I have had my Powerboost for a few months now (5,500 miles) and really loving everything about it. One thing that I am trying to determine is if this high pitched whistle sound I am hearing is normal. I know the backup beep. I also know the safety hum that is there until 18 or so MPH. However, I also have this whistling sound during acceleration up to 60 MPH or so. This is the first time I have had turbo boosters, so was thinking that could be it, but it also seems to happen when I am on full electric. It is one that the pitch gets higher as the RPMs increase and then goes away/reduces as it shifts gears. It would be good to hear if anyone else hears this or not so I can determine if it's something that's normal or should take in.
Thanks.
