,,,,,i had this exact same problem with a new Toyota pick up....at first dealer shined me on but I persisted....they pulled engine and replaced short block under warranty....problem solved....JB

 

weird, so a lot of people are saying this happens right after an oil change and thats what happened to me. but now after a couple days later it does not make the noise anymore. Should I still take it in?

 

Just show your service rep this link let them know this is your car... they fixed everything when Showed them

Good Luck

 

Sorry to bump the old thread.. however I just took my car in for the same issue ..
According to the service rep noise is coming from the camshaft... hope it gets fixed!!

 

Of course I started getting this problem after my powertrain warranty had lapsed. So does anyone know exactly what the problem is and what the corrective action is? I wonder how much it would cost to fix without warranty...

 

I'd like to know this too. Noise began at 75k.

 

I wonder how much it would cost to get this fixed at a mechanic shop for those who are not under the power train warranty anymore

 

If you got your recall work done, you should have received an extended warranty for your powertrain (100,000 mi?).

This should be covered under that shouldnt it??

Hope you guys get this resolved. They redid my camshafts when they had the engine apart to do the recall. Havent heard the noise since that.

Somewhat maddening that this happened at all. Good luck guys.

 

i have a 06 awd gs300 and i get a rattling noise as well. only difference is its on a cold start and only a cold start. =/

 

Just got my car back from the dealer.. let me look into my invoice and see what work/part was changed/performed... FYI, I got the work done through the warranty so I won't know the cost.. Good luck!!

 

If you peeped through the invoice the one you signed but couldn't keep, you would see how much they billed Lexus.

 

Sorry it took a while.. i completly forgot

Im just typing out what was on the invoice..

Is this a service that has to be done?

 

I had them check the whole engine for something like that. I honestly only told them that i had that noise so they can check the engine for everything else. But after a cold start and engine inspections, not problems were found

 

ditto, I'm at 76k and have it now.
