Sticky/edit as desired mods!

 

That pretty much spells it out for anyone looking for a particular MY feature.

 

Thanks! This is very helpful.

For the MY13, what exactly was updated on the suspension?

 

I could never find any info on suspension changes on the 2011, but here's what the documents show for 2012 and 2013.

2013 also has hydrophobic front side windows..

 

I think someone also said the actual steering rack was updated in 2011.

 

This is awesome! Great write up!

 

All I can say is my current 2013 drives a hell of alot smoother than the 2009, but my previous 2009 had more power being it has I/H/E.

 

So does this mean that the water pump issues with the 08/09 MY went away with the new updated water pump in 2010? I didn't know that Lexus updated the water pump which is good!

 

Yes: the part # changed starting in '10.

 

I have black leather/alcantara in my MY12 Canadian car. I think Alcantara was introduced in MY11

 

what about engine cover? i see silver engine cover and black engine cover

 

Pretty sure only 08s had the silver dash around the radio and silver engine cover. 09s and up moved to the black cover and black dash bezel.

In the OP:

The ISF does not have struts. The ISF has double-wishbone front suspension and multi-link rear suspension with shock absorbers, not struts.

Some models came with stupid popup headlight washers, great parking sensors, folding mirrors (auto and manual) and you could opt for a deleted Moon roof, but ALL came with a fantastic NA V8 cheers.

 

I have a question for the infotainment panel for the ISF. Why do some ISFs have at the bottom the following buttons: AM, FM, DISC, AUX while other ISFs don't and instead have < ch track > eject?

Is it a model year difference between pre-2012 and 2013+? Or is it due to a package option?
