Final results from Lexus Customer service.
I was just informed Lexus has decide to pay 50% of the cost to repair my vehicle. 20 days beyond the 9 year warranty and they only want pay 50% of the bill.
As of today, at least to me. Lexus is just another car company.... Good luck to everyone with a 06 - 10 IS250. If I was you I would get rid of the car asap.

Hi guys, I have a 07 IS350 and I just got that check VSC light turn on yesterday. I've been skimming through a couple threads about this and I've seen some saying this isn't a problem with the 350 because it has dual injection or something like. Can I expect the same fix if I take it to the dealers? Yesterday after washing my car, I turned it on only for the idle to feel like it would die. Waited a little while and it ran normal but the little guys were still on. Drove to work this morning and it drove normally. Is this a common thing with the 07 IS350 as well? Car has about 103k miles but no spark plugs change yet. Maybe tune up needed?

Not Carbon build-up
melIS350,
I have virtually the same car, an '08 IS350. I have approx. 178,000 miles on mine. The IS350 has different pistons and rings. The fix for the IS250 oil blow-by is replacing the rings and pistons, for the most part. We don't have the same issue because ours is a different engine. But do run premium fuel because we still get oil burning (Carbon build-up)...most cars do to some extent. Even more in high-compression engines and it makes a huge difference in keeping the inside of your engine clean.
Now for your troubleshooting. If the car was in perfect running condition, before you washed it, I would immediately guess that it is a faulty electrical connection somewhere throughout the ignition. If your VSC came on then I would plug an ODB reader (under the steering column) and get the code that your computer is spitting out. Then you'll know exactly what seems to be the issue. I have mine on all the time for one sensor or another. I had a different car (Chrysler...ya ya I know) but it had a faulty crank sensor connection and when it got wet it wouldn't start either. If I went through a huge puddle of water it would even shut right off while I was driving. Sounds like the car wash was the culprit in your troubles beginning. So first guess would be a bad electrical connection shorting something in the ignition circuitry. And I would assume your car dried out by the time you went to work and this is why it started and ran fine.
Anyway, I would recommend you change your sparkplugs as you will for sure benefit from it and they're definitely due. I changed mine around 145k miles and found a huge improvement in performance and fuel consumption.
Plug it in to the ODB reader (Buy one for about $60 and up) or get a mechanic to check and let us know what you get. If you have time, look around and see if you see any faulty or loose wiring connections that are exposed.
Good luck...sorry for responding with an essay.

Why do you conclude your Lexus IS got carbon build up without knowledge ? and your Lexus is an IS350 ? IS350 using port injection to bypass the valve therefore NO CARBON BUILDup for IS350's Engine, you only get normal build up like other regular car. KIS350 just pointed out something helpful !

So my car misfired and made some god awful clanking noise (which it has made before when it starts to misfire) and lexus wants 31hrs of labor to just do the inspection to see what is wrong with it. I am assuming this is related to the carbon build up, but they are reluctant to agree. I will attach a video, let me know if you have any thoughts.

The above clanking sound is not related to the carbon build up. There was some recall early on with certain IS engines for making a sound like that upon start-up. But I thought the noise should go away once up and running. Not sure if it's that or not.

Is250 2008 awd Canada engine oil burning
Hi guys,
I recently purchased a is250 2008 awd and I got a light saying low engine oil fuel check and I filled the Synthetic oil but seems to be burning out faster then it should. It has 139km on it and four recalls have been done wipers gasket fuel pressure sensor. Can Lexus fix the burning oil problem for free if I don't have warranty? Someone please help me I just bought the car last week
