My 2007 Prius has just under 20,000 miles. Over the last few days, I'm feeling some hesitation, slight shaking, while driving at both low and higher speeds. The emphasis is on slight, very slight, but it's there. It feels like a fuel flow problem, but I'll check on the tires, too. Has this been a frequent complaint among owners? I'm setting up a dealer appointment. All help appreciated.
The only time I've felt a slight 'hesitation' on my 04 or 09 was when the ICE cycled on or off. Are you sure it wasn't the ICE? Had it warmed fully? Was the outside temperature higher/lower than it has been lately? Have you changed brands of gas?
Mine too - but mainly when the ICE cycles on. It feels just like I drove over a small bump in the road.
It's not! New members sometimes post in the wrong forum by mistake. Generally, the result is they get few replies to their question. Will55: PM a mod and ask them to move this thread to the appropriate forum where people will see and reply to it.
Unlikely to be a problem with the fuel system since it would probably throw a code and light the MIL. Let the dealer scan it under warranty (though they may try to charge you for "diagnosis"), because if it becomes a larger problem later you have documented it's first appearance under warranty.
The OP did not mention that any warning lights came on so its not likely that any DTC will have been logged. My guess is that firepa63 is on the right track and/or the OP got slightly bad gas during the most recent fill.
