    Hello,

    My 2007 Prius is making the sound of "a sewing machine in distress" with an occasional high pitched noise (only as I accelerate +50 mph, uphill). Very new problem. Will post video as soon as it finishes uploading. I replaced transmission fluid and am still having this issue. Going to try spark plugs later today. Are any of you familiar with what may be going on? Praying it's not a fuel injector or the pistons. I don't know much about cars but I have been searching the prius chat for answers.

    What does the "state of charge" bar graph look like on the central display (MFD)?
