Hi all, so I took the car in on Friday to have it checked. My history is:
- Oct 2012 - top engine clean at dealership, after having the rpm dipping under 500 at a stop light (car shaking, almost stall like symptoms) after going on hwy
- March and then May 2013, very similar incidents where stopped at traffic light, rpm would go down for a second or so, then go up to about 1000rpm then back to normal
-June (last Friday) - they checked the car, no error codes in current, pending, or history queues
Car is an 07IS250 AWD, never had any lights coming on.
So my conclusion is that there is a little glitch in the onboard computer/ fuel injection that is causing that temporary drop in rpm in the transitional state from running to full stop. It is very intermittent so diagnosing something like that would be very hard.
Am I onto something here?

That sucks, thanks. What makes it suck even more is that I am in Canada where there is no official confirmation of this issue whatsoever, and my car is not under warranty anymore.

Is there a way to prevent this from happening or decreasing the chances of it happening? After some research it looks like my recently purchased 2008 is in the affected VIN range which sucks and is very disappointing. Makes me question my purchase of this vehicle or at least year.
I've read tips like changing oil every 5k or punching the gas every so often but not sure how much it helps or if it even helps at all?

nothing you can do as it's direct injection and that's the way it goes. craziest part is they have not done anything to prevent this in the 2014 new models either. same old engine!

That was plain stupid on their part. The more educated the buyers the more they'll lose on new sells. Plus a lot of us with second generation would not considering to upgrade to basically live with the same fear.

Wow are you serious? Even on the 2014 models? Why wouldn't Lexus address this at least in the new models!? This is my first lexus/toyota and I'm not familiar with them as a company.

Don't they use different pistons or something? That's part of the recall, and I thought that was why the newer models (2011+) don't have a recall/TSB for this issue.
If you're talking about the direct injection technology, there must be a good reason for keeping it, since a lot of other automakers use the same tech in their engines.

Finally getting my car back today after dropping it off 3 weeks ago. It developed a front axle leak, and they were able to take care of that as well. I'm excited to drive a "new car," but I have gotten quite used to the power of the IS350 loaner they gave me.

I just picked it up! Drives like a new car! Love it! It idles smooth with no vibration, and even shifts smoother. They had to take apart my transmission/axle since there was a leak when putting everything back together again.
I took it to Stevens Creek Lexus. My only gripe would be that there are a few light scuff marks on the driver door (probably one of the techs keys/belt rubbed against) and on the side of the hood and fender. Asked them not to wash it so I can wash it myself so I don't get swirls in my paint, but I'll take a closer look when I get home.

Quick follow up. See page 44 of thread for initial post.
Dropped my car of Wednesday morning at the dealership. They had a brand new comp. car waiting for me with a full tank of gas - the Service Rep. told me the dealership is covering the gas.
Thursday evening I received a call stating the car was ready for pick up. I picked the car up this morning.
Here's a short list of what the receipt includes:
Qt. Part (reciept notes warranty included on all the parts below)
(1) Gasket
(2) Super Long Life C
(1) Replaceable ELEME
(1) Ring Set, Piston
(2) FIPG Oil Pan
(3) Non-Chloro Brake C
(6) Piston Sub-Assembly
(1) Engine Oil Change
Does anyone know what "warranty" comes with the parts? Forgot to ask the dealership.
Thanks!
