I personally wouldn't want to keep the car and have it strand me. I'd let the dealer keep it for a while and let them diagnose it. Also, check the odometer reading before and after to make sure they didn't drive to California or something. Good luck!
I would say your battery is fine if you can crank it 20 times and still start the car, well eventually. If your battery is fine it could be a defective starter? Did you do any modifications that required you to unplug anything? If so maybe one of the plugs isn't seated all the way?
I would drop it off at Lexus and let them figure it out being it is under warranty. Please report back when you figure out the problem.
I had a similar issue with a different car, how long ago did you install the headers? Was the O2 sensor on the header re installed correctly? (if there is one) Sometimes the metal from aftermarket headers can fry the wires. Sometimes you have to extend the wires on them. Bad O2 sensor can give the car the wrong A/F ratio which can cause the car not to start
Most performance mods need a watch and timed course to demonstrate actual improvement. Few deliver the advertised claims. Many are actually worse than stock. The best performance mods are made to the driver.
