i checked it by another way
while driving, you can check your speed in digital numbers in the hidden menu, ( maybe through the GPS) and it is clearly less than the manual speedometer pointing.
u don't need an out side GPS to see the difference,
try it by your own car in the hidden menu and see it.

At my dealer as I type this, for an oil change.
Started into the speedometer story, and the service advisor interrupted me - "It's off by about 3 mph, right?" Yep.
So they obviously know about the issue. The thing I mentioned to him is that my odometer shows 20,000 right now, but assuming the 5% average error, I really have gone only 19,000 miles. In other words, Lexus has "cheated" me out of 1,000 miles in less than 18 months, and at the end of my lease, it will amount to about 2,250 miles.
Put another way, if I stick to my 45,000 mile limit on my lease, I actually have only about 42,750 miles on the car when I paid for 45,000; conversely, if I go over my allotment by a couple thousand miles they'll expect me to pay for the excess miles, when I actually don't have excess miles.
Acura lost a class action over this exact same thing, and had to extend leases and warranties by about 5%. I wonder if anyone will care enough to challenge Lexus on this?

I could be wrong but I believe the speedometer and odometer are calibrated differently. The odometer likely reads pretty accurately or they'd be liable for multiple lawsuits. The speedometer on the other hand ALWAYS reads fast on ALL cars. This is designed to prevent speeders claiming against the car company that their speedometer was reading slow and that's why they got a ticket!

Ditto here on my '11 LS460. FWIW, when I bought this 2 year old CPO, I had the dealer put 19" premium wheels on replacing the 18"ers. I have always thought this was the cause but never discussed it with the dealer.
