Engine stalls when turning left reducing power steering boost until driver lifts foot from gas pedal and repushes to regain power steering boost on city streets at low speed from stopped position.

I am not sure it it is engine or fuel but my problem is as follows: While driving and with no warning my 2013 Lexus ES 350 hesitates to the point of almost stopping in the middle of driving on local and highway roads. It seems to be getting worse and I have taken my car to the dealer and was told they did not find anything wrong with it. In researching this problem I have come across two similar complaints on www.carcomplaints.com. this is a dangerous issue when you lose acceleration when it is most needed.

Ever since car was purchased @one year ago, there are occasional 1-3 second hesitations upon acceleration. These occur from dead stop or at low speeds. Two dealers have examined the computers, finding no evidence that the problem exists. They also say no other local owner has complained of a similar problem and the manufacturer reportedly has no record of such a complainant nationwide. But a number of different passengers in the car have felt the hesitation and asked what's wrong. I wish I knew and I wish Lexus knew. Since this has happened many times when I was changing lanes on a surface street or the freeway (socal) or making left/right turns with oncoming traffic, my fear is that my vehicle is going to be hit, although I am as careful as I can be when changing lanes/turning because I know at any time the car will hesitate for a few seconds. I experienced this problem noticeably, as did other owners, with previous year models, but am assured by dealers and the local district office that Lexus has solved it now. I only wish!

Lexus ES350 stall or hesitation problem on 2013 model. My car frequently but intermittently hesitates when accelerating from a stop or rolling stop position. I've had it about 8 months and it has probably stalled at least 100 times. Tulsa's Lexus dealership says there's nothing wrong with it and that Lexus designed the car that way for fuel efficiency (yes, that is what they've told me, and with a straight face). My 2010 ES did the same thing, and my 2007 ES did the same thing. You'd think I would have learned my lesson by now and bought a different brand of car. This is an extremely dangerous problem when pulling out into traffic. I would not recommend a Lexus to anyone until they get this problem fixed.
