Problems with 2003 Lexus ES 300 ENGINE AND ENGINE COOLING

On march 26, 2010 my husband and i were stopped at a traffic signal, (with my foot on the brake as you would expect), when the car suddenly accelerated at full throttle. in the brief but terrifying moments that the car was out of control i unfortunately collided with another vehicle as i threw the gear selector into neutral. *tr

There is a delay after sitting at a stop light and then at take off. the dealer could duplicate the problem and the manufacturer and dealer states that it is the new design. *ak the problem would also occur when making a left turn, merging into traffic, entrance ramps, intersections and parking spots. *sc *jb

Strong sulfur smell inside car when stopping after brisk acceleration. a/c in normal setting. lexus aware of this problem and there is even a service bulletin on sulfur complain smell. odor is so strong that sometimes people get nauseated.*ak i would have never bought this car have the dealer make me aware of this problem and they knew about this defect before i took delivery of car. need nhtsa help since there are many lexus owners complaining about sulfur smell and lexus is ignoring us - i guess they have a major problem and do not know how to fix or correct problem. they even told me to use only amoco premium since they claim it has the lowest sulfur content. also, if the sulfur smell is getting inside the car how about the carbon monoxide which is also getting out of the exhaust. all these fumes are being sucked in by the a/c system and i'm sure that in the long run somebody will get sick. - we, lexus owners need our government to investigate this issue since lexus is trying to ignore these problem for obvious reasons. thank you.

There is a pronounced hesitation when the accelerator is floored. this lack of responsiveness leaves the vehicle and the driver exposed to accident and injury. lexus had offered "repair" for this, but it does not work on all types of models. they now state that the auto is working as designed. *la *jb

The vehicle had problems picking up speed, when the accelerator was pressed the vehicle did not respond, it sounded as though something was ticking inside the vehicle. the consumer contacted the lexus manufacture and was told they were aware of the problem which was called " the hazard computer module control" but did not know how to repair it. *jb

While driving at highway speed the vehicle jerks and drags, contacted the dealer they said that lexus was doing some sort of computer program update that relates to her vehicle. please add any additional information. mr
