Prius engine vibration for few seconds after engine oil and transmission fluid change

I just changed my engine oil and transmission fluid today since I bough my Prius 3 few months ago. After both the oil and transmission fluid were changed. I turn on the car and tried to have a test drive. The car vibrated for 3-5 seconds when the ICE started. I was worry and then shut off the car. Then I started again, vibration came back when the ICE started again for 2 seconds, then vibration disappeared. since then I didn't have this issue. I have never have this issue since I bought the car. I am not sure this is cause by oil change or transmission fluid change.

The vibration sound like those in early 2010 where people start the Prius in the morning and the engine start knocking for few seconds. And I think TSB said it was due to intake manifold defective design causing misfire. I don't think my car have this issue since it is 2012 and I believe Toyota fix this issue for 2012. Is it possible that after changing oil, oil pump completely run out of oil? I have no idea why and this is the first time I have this experience after oil change. In fact, I have no idea this is because of oil change or transmission fluid change.

Please let me know if anyone know what is happening. Thanks

 

What wasn't fixed? you mean the intake manifold issue? I change both oil and transmission fluid today. And Today temperature is about 65 in the afternoon. The car was not warm up. It was obviously cold since I was changing the fluid. I started the car when I finish changing both fluids. Are you saying that 2012 Prius still have issue for misfire?

 

To your answer, yes,

It was not driven for the entire day except it was moved in front of my house from one parking spot to another (less than 40 feet), which should not heat up the car a lot. Then I pretty much spend two and a half hours jacking up the car, putting the jack stands, removing the panel underneath, and so on..

Is this the reasoning?

 

I add little over 4 quarts for transmission fluid (maybe 4 quarts 2 oz). For engine, I add four quarts. The car has about 41K. The car was moved twice, once at about 12:00pm today with ICE on. The seconds time was right before I changed the fluids at about 3:40pm (I forgot rather I was using EV mode or not). Then I started spending two and a half hours working on it. At around 6:15, I started the car.

 

Oil was Mobil One EP 0w-20, filter is Bosch long life filter. trans fluid is Toyota WS-ATF

 

Since I changed both fluids at the same time, I have no idea what is causing it if it happens to have to do with fluid.

 

What do you mean? what cycle are you referring to? The engine four cycles? or the cycle that the engine kick on and shut off?

 

no code was displayed

 

Toyota did not fix it since 2010? Is there a TSB for this? So this was the same knocking problem of 2010 Prius on the intake manifold?

 

OK, thanks. This is no good, Toyota hasn't done enough testing for their products before releasing their product. This Prius simply use Corolla engine. Is there similar issue for Corolla, Or corolla just uses different manifold?
