ok guess im stuck badly i recently bought this car and now i see this, My car does not have this noise . but it falls under the vin number of the cars that could be effected, i can get the sound and take t to dealer and they will do the work, but idk if it worth opening the engine up im just worry it starts making it, since i just got this car idk if it made it before pr not, i want to know what to do before i go out of warranty, please help

 

They normally charge for 4-5 hours' labor to change spark plugs??? WOW, I did mine by myself in about an hour following the DIY here on the forums! I'm in the wrong business

 

If its not doing it you cant do much about it. Dont let it scare you though, its not as big of a job as you think... The bulletin calls for 6hrs but it can be done w/out a lift in 2hrs (not rushing it). It affects all 06+ GSs ISs up to late 2010 production

 

Where is the TSIB VIN list?
I saw one attachment but it says IS350 only...

anyway if it is not making the noise then I think you should leave it alone, there is no good reason to start disassembly if there is no problem with it.

 

Good point well i end up canceling my appointment since i got extended warranty for 30,000 more mile, ill see if it make that noise later on

 

The bulletins all have range an models listed on the first page

 

This is the 3rd time my vehicle will need this work done. I had the "5th" revision parts installed 1 1/2 ago under my extended warranty. I have to take it in again and will be out of pocket. Lexus corporate will not pay for it. The vehicle was not fixed correctly two times, because obviously there is a design flaw. Is there case/reason for a lawsuit?

 

In your case you probably have a good case for a lawyer since Corporate won't cover it. I don't understand why they wouldn't,...send a letter to the President of Lexus North America.

 

Is there a new LSB out for is250's ? The one that is labeled "EG017-07" seems to cover all vins up to:

MODEL PLANT DRIVETRAIN PRODUCTION CHANGE EFFECTIVE VIN

2WD JTHBK262*72041664
4WD JTHCK262*72014588

2WD JTHBK262*75027761
4WD JTHCK262*75011435

Unfortunately my car still has this issue and the vin number is JTHCK262*72011499

Did he read the vin wrong?

 

Anyone know what the out of pocket expense would be to have this fixed? I had the issue initially maybe 1.5 years ago and had it corrected under the TSIB when I was less than 70K. However, the noise is back again and my car is at 71,700 miles.

 

there is a tsb for the noise that your discribing. the dealer will replace the cam gears if its still under waranty. also change your oil more often. with fresh oil in it, it wont make the noise as much. 5,000mi is too much you shoud change your oil every 3500mi

 

No, you really shouldn't.

5k is too often, based on actual lab analysis of every used oil sample I've ever seen on a 2IS.

Cars haven't needed ~3k mile oil changes in decades... even most manufacturers are going to 7500-10,000 mile recommended change intervals (including Lexus as of the 2011 IS250 which has a 10k mile OCI)

 

If your response was directed towards my previous post, you must've missed what I said. The dealer already replaced the cam gears in my car around 1.5 years ago, per the TSIB, when my car was still under warranty. However, the crank noise has returned and my car is out of warranty. I'm looking for an estimate of what it will cost to have the cam gears replaced again, if that is the only solution to the problem. Additionally, I'm fairly certain changing the oil every 3500 miles is not necessary. Can anyone else chime in on this?

 

Thank you, Kurtz.

 

Dropped my car off at the stealership this morning to have this TSB performed as the powertrain warranty lapses in a few months. Made an awful sound this morning when I cranked it. I get a call about half an hour ago from the Lexus Service Adviser claiming that they couldn't replicate the "grinding noise" when they started the engine a few times today and will attempt again tomorrow morning. In hind sight, I probably should have recorded this morning's start up.
