Engine misfiring at start. While at intersection in city and turning left, accelerating and triggering the combustion engine, misfiring causing jerking and lack of acceleration almost causing a stalled car in oncoming traffic. Check engine light on. Service says misfiring caused by faulty head gasket. Appears to be symptomatic of gen 3 prius.

I owned this vehicle since brand new. It had happened more than a dozen times. When going over bumps or uneven surfaces, with the same pressure applied to the break, the 2012 privus failed to stop and lurched several feet before stopping. We had an incident that we almost ran into pedestrian yesterday when this issue occurs. This is very concerned to my family. We bought this vehical back to the dealer ship where we purchsed it.(expressway dorchester toyota in masschusettes) they said they could not fix it because they could not reproduced at the dealship. The service of manager claimed this is working as designed from the (tracking control). I feel this is a false statement, this does not happened to my other cars that has traction control. Toyota should really starting fixing it before someone gets killed!

There are two things that occur with my brakes. One is a consistent and very loud groan with braking after any length of time sitting idle. The other is when the brakes are applied and I may be over a bump in the road or a pot hole or rocks the car lurches forward quickly as if I have lost control of breaking. Almost like hydroplaning without water present. I have taking the car to the deal consistently since the noise began and yet to have a fix for it. They say there is nothing wrong with the brakes. However I specifically had someone sit in my car to hear the groan because they said they were unable to duplicate it. They heard the noise and again could do nothing to make it stop.

I began experiencing what I described to the dealer as a "hiccup" in my brakes. I complained of this problem the two times I took the car in for routine maintenance (first and next six months), and each time they found "no problem" with the brakes. It was not until this snowy rough winter with all the attendant pot holes in the street that I correlated this braking problem with uneven pavement. I know this happens when my right front tire hits a pot hole, and it may happen when any tire does, but if I'm apply the brakes - especially hitting the brakes at the moment one tire dips into the hole -they do not engage and in fact there's a slight lurch forward, almost an acceleration. The car is going to the service department tomorrow with the hopes that the problem can be located. This truly feels dangerous to drive.

My car has an issue I first noticed soon after I bought it, and that now happens at least twice a week. The date I've entered is the approximate first date I noticed the problem occur. I describe below a more recent instance of the same behavior, the time when it felt the least safe. /// the recurring behavior is that while decelerating with my foot on the brake pedal, if the car goes over an obstruction like a rock, a rough patch of road, or a pothole, it sometimes lurches forward before resuming deceleration. The sensation is of accelerating, but even if it's only that the car momentarily stops decelerating it's disconcerting and in a few instances has gotten me close to an accident. /// the time it came closest to causing an accident was on 3/21/13, when I feared the car was going to roll into a crosswalk as people crossed. With my foot on the brake, coming to a stop at a stop sign, we went over uneven pavement and the car lurched forward while only a few feet from the crosswalk. Several people waited close to the edge of the sidewalk at a bus stop. One of them seemed ready to step outto cross the street, and I braced for the worst. /// ultimately I stopped a few feet before the crosswalk, but the situation felt completely unsafe since it involved losing stopping power while coming to a stop sign with pedestrians present.
