I do not believe for a nanosecond that they haven't heard or seen this issue on any of the Japanese cars that have been delivered already, or in initial testing. Bullshit.

I wish all of you luck in getting it fixed and taken care of, and am very sorry it is happening so early and to so many. I so badly want this car, but not if it's a mechanical turd. 7 years is what I need it to last.

It is a brand new engine I guess they did not worke out every problem before production....
Its a shame knowing Toyota quality....

No issue with my BRZ with 605 miles on it atm. It shuddered once but that was due to a .2 mile drive and I was sitting there letting it run for a little. Other than that no issue.

Mine drops to ~4-500rpm too, with a/c on or off. It comes and goes, and I cant replicate it.

I currently have ~3,300 miles (yes, you read that right).

No codes stored, so they couldn't pull anything. They will have to look at it again if it happens again.

I have a Subaru. Don't think that's the right number.

My fr-s manual did this very slightly when sitting on level ground, but when its on an incline with the nose higher than the rear it was much worse. At first i assumed I wasn't clutching in all the way. I haven't noticed it at all in the past half tank of gas though since I put e0 high grade in it. I'll keep an eye out for it now though.

Interesting, perhaps it is a fuel pump issue.

Does it only happen with manuals? If so, does it change when you press or release the clutch?

Just saying because I think there's often some sort of sensor that adjusts idle or mixture depending on clutch position. If it's flaky, you'd get this problem. Not 100% sure about that, but I think I read about it once on the RX-8 forum.

Thats what I was thinking after this read.

We have also heard an issue with the crankshaft tho. Hmmmm I don't know

Some autos have mentioned having this problem as well, and with the manuals, it happens in natural or clutch in.

I'm having a hard time wrapping my head around this. Can someone provide a succinct description of this phenomena?

My MT FRS is 2 weeks old and I have yet to notice it really drop below 500-600 RPMs except during user error (first time stick shift driver).

Doesnt this happen to many cars? and isnt it only a big issue if it happens regularly like 3-4 times a week) This happened to me previous scion tc 2012 on occasion (like twice)
Havent had it happen yet in the FR-S (~150 miles)

Doing a quick google search brings up essenitally similar concerns with a whole variety of vehicles. (not saying it isnt an issue though)

The idle dipping a bit when accessories are in use is normal.

But dropping down to ~4-500rpm and taking a second or two to recover is not. It usually happens when I pull up to a red light and take the car out of gear. But as I said above, its not constant.
