i cant get better than 18mpg in the city. Every possible maintenance is up to date, tried ecu resets etc...
highway I can get 23.5 mpg but city driving mileage is horrible. Worse than my old RX350 that weighed like 600 pounds more.

The LCA bushings aren't up to the task from the get go. My '06 started eating tires early on. I did an alignment, no luck. Replaced them with new OEM bushings and another alignment, no luck. I swapped to FIGS bushings and all the terrible tire wear ceased. On my next IS I just did that on about the 3rd day of ownership and never had any issues. The 3IS has the same bushings and suspension design, it is just matter of when, not if it will happen as far as I'm concerned

You definitely should have seen it by now. You’ve checked the inside part of your tire recently?

That's surprising. My stock summer tires were showing signs of inner tire wear (not a lot) by 8,000 miles which is when I bought my Michelin A/S 3+ for the winter. I have the GS-F/RC-F LCA bushings installed though so I'm curious to see how my Michelin's look when I reinstall the summer tires in about 2 months.
Is Lexus Quality getting worse??

Mine also, to the point the front tires started shredding!!
Me too so rotated the rear tires and they highly recommended a 4-wheel alignment - costs $180. Did you get an alignment?

Alignment won’t help in this case. You need stiffer lower control arm bushings. That’s why I got the RCF/GSF bushings and installed them.

Just a note I had an oil change, filter and plugs changed at 65K so the ppl that will jump on me for not servicing at 60k can rest well at nights now.

So the big girl is getting up in age she is at 67K and going in tomorrow for her big 60K service, What bushings do you recommend to resolve this issue before it even starts.

Figs or RR Racing poly bushings are popular but much stiffer than stock so you’ll feel a little more vibration etc. The GSF/RCF bushings are an option too. More oem and less stiff, people seem to be getting good results with these (I haven’t put enough miles on mine to see the efffects yet).
