My wife's avalon hesitates for 3 or 4 seconds intermittently during acceleration without warning. The yellow triangle light comes on the dash board during the hesitation. I seems to occur more often after turning left and accelerating. I am concerned about her safety when entering traffic and or crossing a road with an unexpected hesitation. Our local toyota dealer says they are not aware of this kind of problem and are not able to diagnose it. We would like to know if this is occurring else where and what we should do about it.
