i really dunno about these stuff, it would be great if its 5years
but i tho it was 3years, and then you can extend it?

i use chevron with techron premium. there is always going to a bit of a vibration, but it's sooo much better now. we will wait to see if it tries to stall anymore.

To clarify- you're both wrong.

A new Lexus has a -4- year warranty bumper to bumper, and 6 years on the powertrain (engine/transmission mainly).

This ought to be covered under either if the problem is carbon build-up in the engine.

(mileage limits respectively are 50,000 miles and 70,000 miles)


USED but certified Lexus vehicles have a 3 year warranty from date of used sale (up to 100k miles).

You can buy the Lexus extended warranty on any Lexus that is still in its original 4 yr/50k mile warranty period.



Oh, and the brand of gas you use won't make a difference... from everything I've read so far it's a problem with the design of the DI-only engine... which is why 350s don't have this problem.

^^ Kurtz is 100% about the warranty and the gas, carbon build-up is just a normal thing in engines...

I am not too familiar about carbon build-up on these DI engines, but I do know that if it gets bad enough to get on the throttle body, you will get a slightly rougher and lower idle (really bad on Toyota 4-cyl engines)...as soon as we do an upper induction service and clean the throttle body, problem gone...

Now don't get too overboard with this service...if it isn't covered under warranty, it could be $100 or more at a dealership...and if you plan on doing it yourself, if done wrong you can hydrolock your engine...

blah blah blah with the hydrolocking.

throw some seafoam in the brakebooster line and you're good to go. you don't need to pay a lot of money to fix a simple problem.

throw in a can of seafoam in the tank

Or use water instead of seaform for the vacuum lines. Put your favorite fuel injector cleaner into the gas tank.

BLAH BLAH BLAH until you hydrolock your engine...

I am trying to give good advise, not bad advise like just throwing a can of seafoam into the vacuum line...if you add any induction cleaning product too fast, you will hydrolock the engine...seafoam's own website warns people about adding it too fast, check it out...

easily done yourself, just be careful...

having the exact same problem..im in South Africa,my lexus dealer said "no fault found" when i took the car in..car has about 80000km on it..

Being that this is a fuel problem isn't there an emissions’ warranty? If I’m not mistaken it’s a longer warranty! Also being that this is clearly a design problem it should be actionable. Toyota doesn't need any more warranty issues!

Koz

exactly! the tech clearly said it's a design issue. lexus/toyota can't afford anymore issues right now or ever for that matter.

The emissions warranty isn't much longer than the powertrain one (8 years/80k miles versus 6 years/70k miles), and would have nothing to do with this issue since this has nothing to do with emissions.
