Lexus IS250 4GR-FSE Engine Carbon Build-up (merged threads)
#886
to the folks that have had their pistons done already i have a question. did the car vibration come back already at a light? mine did about 300 miles later. :-( i don't feel it as bad on the doors, but the sterring wheel is just as bad. Funny when they give me a loaner i never feel it on any of those. what gives???

The service consultant at Lexus told me it's a "permanent fix" but I really doubt it. Also, rumor about to open up the throttle once in a while reduces the build up.
I plan to keep the car for long time, but this issue made me want to trade it in sonner since the replacement for piston/ring costs about $6000+ at my local Lexus dealer.

yes i too thought i would keep the car, but now thinking only until when my extended warranty is up at 100k since this could be very costly in the future if there are more problems.

Same here. I'm picking my car up tomorrow. Still got 2 years and 30k left on the CPO warranty, but i'll see how the next 10k miles go (should be done by the end of the year). If it's still having bad carbon issues , i'll probably just trade it in for another Lexus. I'm more worried about how the new piston job will hold up tho then the carbon build up. I know they had their best techs working on it, but still...

Picked up my car yesterday, drove it about 40 miles home and all I gotta say is that it feels freicken brand new again between the new piston work and the spark plugs i had replaced. Longo Lexus really did a good job on all the work and the car runs great. I don't know how long it will continue feeling like new, but i'm hoping a while at least. But just driving it on the highway its a lot smoother as you accelerate and doesn't feel sluggish at all like it used to before I took it in.
I'll update again when everything is broken in and I get the oil changed in like 1,000 miles to clean out any shavings and stuff that might be floating around in there.

is it correct to say that the top engine cleaning is only a temporary fix to the rough idling problem? I dont get the stalling but i get vibrations and slight rough idling at stop signs especially after pulling off a highway.
My dealership is doing the top cleaning now but is not replacing any rings or pistons and i do not have any warning lights on. Should i ask them to do the other TSB with the replacement of rings and pistons or does the top cleaning suffice?

heres my timeline.
Within the last 1.5 years i had: top engine clean, top engine clean, replaced pistons. Pistons replaced about 4 mothes ago and I noticed the car acting up last week while idle. Not as drastic as prior but you can still notice it. Car is now getting Valve springs replaced and valve containers.

With aftermarket warranties it depends, If your dealer can verify the issue they will send an invoice of repair costs to the warranty company for approval....then it's up to the warranty company to say yes or no. With a high $$ repair like replacing the pistons...it may or may not be a headache to get it approved.

The updated piston rings listed in the TSB were used in production from 10/2009 to 11/2011, there is an even newer piston ring part number from 11/2011 on (13011-31240). The production dates of the VINs listed in the TSB do correlate with those dates, so with that information I would say that yes VINs after the ones listed in the TSB DO have the updated parts, and newer 2012 models have an even newer piston ring set.

Looks like mine barely made it. TSB shows TMK 4WD prod change A2032832, mine is A2033xxx. Phew...
Hopefully nobody will need the even newer 2012 rings in the future.
