Well it was a really tough decision, i was going back and forth on it, but decided against buying it. When it comes down to it, it came down to the issue with the carbon buildup on the IS250's. The car doesnt have any rough idle issues right now from what i understand, but it probably would at some point. Given the 9 year window for CSP is only a year away for this car, i felt it was too much of a risk if that 9 year window went by and i start experiencing issues after the fact. From what i understand even if you experience the rough idle, but the computer does not store the misfire codes, and the dealer can't repeat it, they wont perform the work for it. Thats a huge expense to swallow if it was not going to be covered by Lexus after the 9 year window. I hope i made the right decision :-\ I guess ill have to look into a used 350 or something else.
My question is why does it only affect the 2006-2010 MY? I mean 2011-2013 Gen II have the same engine 2.5L, as does the Gen III 2014 MY. Maybe too new still? Isn't this carbon buildup issue eventually going to hit them as well?
