Have you found out the cause of this ?

Mine has done the same thing to me :(

@TAPmaintenance They have not found a root-cause, but the good news is that this has not happed to me in over 18 months. The dealers/service shops will deny any issues since its impossible to replicate it during a service visit.

UPDATE: I had a 7-day trip last week and left the car at the airport, when I started the Prius early morning (28 deg cold), it started as expected! No issues!!! This was a very good test and the Prius passed.

I'm not sure about the normality of this one. I have heard many other cars do that and of course after a week its not your normal startup. Any resolution? BTW it is really sad to see all the anti Prius and anti hybrid comments. Really? Likely these people have never been in one much less owned. I have a long history of vehicles, including most luxury class and a few that quadrupled the Prius power/ handling, think 24psi track ready. With all that behind me, I am very happy with our Prius.

you need to put Stabil, or drygas in it. mine did the same thing until I started putting the blue Staybil in the gas about once a month or so

@PlymouthVT The run away wide open throttle automatic cruise control is a prius exclusive. Part of Tokyo revenge

@AthenasConquest Bullshit.

@jaggass  The engine comes on when cold no matter what to heat the cats to meet its Zero emissions mission.

its normal for the valves to clatter like that when cold?

i sure hope toyota doesnt expect its engines to last long...

[GoMetricToday]

Mine did that as well. I found out that it was because I had turned the car off shortly after the ICE started and then restarted it a minute or 2 later. I was told it was because of gas vapour that was trapped and it cleared up within seconds of running.

[jaggass]

how does this hybrid work? didnt think the engine was on when stationary.

[mikhailSRT4]

its a toyota its normal for engine to knock

[ChuffChuffWoo]

The car has a hydraulic valve control system that uses the engine oil to operate - once this is up tp pressure, all is ok - engine if fine - no worries!
