My 2011 IS 350 F Sport is about a month old now, and while I rarely use the paddle shifters I just noticed something today that wasn't happening after i bought the car....namely it doesn't work. I'll shift over and neither the light with the gear placement is lit up on the dash, nor do I feel it shift if I shift up and down. Am going to take it back to the dealer to ask, but I figured I'd see if anyone on here has experienced the same problems?

First off you should know that the paddles are not shifters. They are merely gear limiters. You have the ability to limit the upper gear on the car as long as your speed is sufficiently low.
Next, you can temporarily use the paddle gear limiters while in "D" mode, but only if you are moving. You cannot temporarily limit gears in "D" mode if you are at a standstill.
Finally, while at a stop, if you shift the car from D mode into S mode, you should see the default limiting gear set to "4" (S4). From this point, you can choose to increase or decrease the limit as you please while at a stop. Once you start to move, you are subject to the speed constraints. In other words, you can only limit the car to 1st gear if you are well under 40 MPH, you can only limit the car to 2nd gear if you are well under 60 MPH, so on and so forth.
So to conclude, when you shift the car from D mode into S mode, you should see S mode along with a giant "4" light up on the dash. However, you should not feel any sort of shifting because you aren't shifting the car at all. You are merely limiting the car's upper ceiling to 4th gear.

makes sense. I don't have the giant numbers lit up on the dash. I had an is 250 and had no problems.

Here you go, this is what it should look like -

Skip over to :40 seconds or so and you'll see what it should look like. Are you saying that "4" does not show up when you switch the car into S mode?

The S-mode and accompanying paddle shifters are not really "shifters" in that they don't actually shift gears, nor were they designed to - they're merely a mechanism for manually selecting the gear range. Following is Lexus' description of the paddle shifters, taken from the New Car Features section of the FSM:
Here are the rules by which the different 2IS transmissions allow downshifting:

As you can see, 4th gear allows a top speed of 109, 113, and 109 mph, respectively. You have to be going insanely fast for 4th gear not to be appropriate for the speed at which you're driving. Simply put, if you're going too fast for the gear you want to select, it won't shift.

Also, the shift paddle switch is adopted, which enables changing the shift ranges while the driver is holding the steering wheel. Thus, the driver is able to shift gears with a manual-like feel.[/left]
An S mode indicator light which illuminates when the S mode position is selected and a shift range indicator light, which indicates the range position, have been provided in the combination meter.
This Multi-mode automatic transmission is designed to allow the driver to switch the gear ranges; not for manually selecting single gears.

What has changed in the 2014 IS350 f Sport?
The paddle shifters seem to work as shifters. When the car is stopped and in D the "number" on the dash is M1 and it doesn't change when the paddles are depressed.
