Engine problems

[Dell W]

Hi all

I have been browsing through some YouTube postings and video's on the IS 250

and there are quite a few posts of major engine problems that require a complete

engine rebuild due to piston ring problems causing a buildup of carbon deposits 

which in turn caused uneven tick over and difficult starting problems. These where

all on US sites effecting IS 250 & 350 models and Lexus US where doing the work

under a warrantee claim. Does anyone know if any of the models this side of the

pond have had this problem and if so was the repair done as a warrantee claim.

Nothing to report over here. To my understanding it's to do with the poor quality petrol used in the USA

Much of the problems in the US are down to the reluctance of owners to using the correct synthetic oil. They are stuck in a 1950's time warp where they have always used basic oil called "Dino" oil and should be changed every 3 or 5 thousand miles, but the leave it for 10,000 miles as in the handbook.

Hi

If it is a case of using the wrong oil or fuel then why would Lexus  do a complete

engine rebuild under a warrantee claim?
