mine has done the same thing to me a handful of times and i'm now at 40k. said something to the dealer yesterday about it when i was in for an oil change since it happened again that morning. they checked the computer for any codes it may have thrown but found nothing. they said i most likely have carbon build up and also need the injectors cleaned. they suggested a throttle body cleaning and injectors cleaned. i say a bunch of b.s.! the car is too young for all of that and i only use premium fuel since i got it brand new. what do you all think?

My 07 IS350 does the same thing, just drive it hard sometimes & clean the injectors by buying a bottle of Chevron Techron & pour it in before you fillup with Chevron premium

I just had this symptom on my 2012 IS250 for the very first time. Is this really normal on the newer IS?? Anyone else got this??

Had this happen to my 2010 IS250, 3-4 times at a stop light, 2-3 times while shifting to reverse after cold start. I had the dealer look at it a couple of times, but found nothing. Could be related to the TSB for older IS250.

Chicagi23, how long does the symptom reappear again during those 2-3 times??

Anyone else with newer IS experience this?

I only had it once on my 2012 IS250 and then I haven't seen it for many days now. What should I do to prevent this from happening again?

No, it's not "normal". Could be any number of things from a dirty injector to carbon build-up on the valves and pistons.
