Hi All, I have 2008 Prius with 80K and I will try my best to give all the information that I can. The past few days during about 10-15 MPH driving, my car started to shake a little bit when I try to accelerate. It doesnâ€™t want to go no more than 5-10 MPH and I feel like I was driving on the small bumps. It went away after 10 seconds. Again, I can't duplicate the issue. It happend only twice. Could this be related to 12 V battery issue, tires issues, transmission, fuel injection, spark plugs? Â· About a year ago, my 12V battery die because I was listening the radio for a couple of hours and turn the light on. With the help of my neighborâ€™s car, I was able to jump start my prius. I got of course I got a message complaining about â€œcar needs to be on the flat, and you canâ€™t drive, etcâ€¦â€. The message went away after a few minutes start and restart and the car has been driving fine since. Â· Recently, I have seen a couple of same messages again while on the park. Â· Have some decent threads left in my Michelin tires.
