In reading posts back to 02-03 it's apparent the tranny "hesitation/surge" problem has been around awhile and Lexus has done little if any to correct it. My dealer basically shrugs with a "that's the way it is and there's nothing we can adjust or change to fix it." Our 01 Camry is about as close to a perfect car as we've ever had but the so called "luxury" Lexus is a real disappointment. Oh well, it's only a car.
