Hesitation/Stumble when first accelerating from a stop
I have a 2022 NX350 and in the past few months at times when I start out from a stop the car has almost a dead spot in the gas pedal for the first second under light acceleration. It seems like the car hesitates or stumbles at times when I am starting out for the first second or so from a stop. I always turn off the auto shut off so the car is always running and not starting.
I always have it in normal mode, not echo mode as it seems to have less power in echo mode. I have also put it in sport mode but it still has the same problem. This problem does not every single time I start out, maybe only 50% of the time.
The car is almost a year old and has 4,000 miles on it so it will go in for it's first oil change next month. I will mention it to the dealer and see if they know about but I figured I would ask here too to see if others know of a solution.
Aside from that I love the car and find this forum has so much useful information.

All the best with it, I am sure it will get sorted.

This has not been my experience as well. I find from a stop its very responsive. I have on the very rare occasion noticed that if I slow to almost a stop (down to 2-3 mph) and then hit the gas it can take a 1/2 second to respond, but outside of that, generally responsiveness is very good through most other driving conditions.

I have this exact problem. Hesitation from a stop. I have narrowed it down to a certain situation. When the temperature rises above 90 degrees my NX 350 will hesitate from a stop to a point that I consider it dangerous. (Start/Stop is always disabled) If I need to cross a busy intersection it becomes quite scary when my NX stumbles for a couple seconds and then takes off. I have taken it to Lexus multiple times and they say the usual "We have never seen this before" and "It operates correctly" and "There is nothing wrong with your vehicle".and "There is something wrong with the way you operate the vehicle". Huh? This is my 4th Lexus and have never experienced this hesitation issue before....
I rented another NX 350 using Turo and that car had zero hesitation issues with temps above 90. But I obviously don't know how to operate the vehicle....
I have learned to master my cussing skills when crossing intersections. It seems to help.

Sorry, I hate it when a dealer just says they all do it or we have never heard of it. My very first car has a major problem starting from a dead stop also. Dealer totally ignored me until my uncle, that owned an automotive repair shop, called the service manger. The problem suddenly had a fix. LOL
But I will say, my 2017 CRV 1.5L turbo lag never bothered me until one day I made a left turn and noticed a car coming up way over the speed limit. I noticed for the first time that turbo lag and it was scary- it seemed like forever before the car picked up speed.
FWIW, I have now the 350h. I had a similar situation a few weeks into having the car. I knew about the instant torque, but it was a totally different experience with no lag.

There is a you tube reviewer from California called Milesperhr and he reviewed the NX F Sport and talked about this lag as well. It was a bit concerning.

I took the NX in for in first oil change today and mentioned the hesitation problem to the service advisor. They claimed they took it for a ride and didn't notice any problem. I guess I will just live with it until the cooler weather returns and see if the problem goes away.

On my last RX350. I had a problem taking off from a stop. But it was always when I didn't come to a complete stop. The car would hunt for the right gear to go to. So, for a few seconds it would just hang.

I had a vehicle that did this but not all the time. It had something to do with the car starting in second gear when on a flat gradient or slightly downhill. Sometimes the transmission would get confused and shift down to 1st before accelerating, this would cause a pause and a small transmission jolt. Funny thing is, it also had an 8sp, stop start tech and a turbo engine.

I consider it a safety problem and maybe if I word it that way the dealer will look into it and figure it out. I think it will take a ECU software update to fix it as it seems to be fuel injection problem but that is just a guess on my part. If I find a solution I will post it, if enough of us complain maybe Lexus will see it is a problem and fix it.

You want me to lie to you like the dealership and tell you there is nothing wrong with your car? Then just pay the nice girl at the end.
Dealership mechanics don't diagnosis problems they are just parts replacers. They fire the parts cannon and hope something works. Most times it does.
Dealerships have seen and heard of all the issues long before you but they wont admit it because then they would be on the hook to fix it. They would rather move on to the next flat rate or warranty ticket.
I have had many friends in the dealership service dept. and they tell me all the little lies and secrets they keep from the customer.
YES! Your car has a definite problem but the dealership does not have a quick answer and they don't hire people that can diagnosis hard issues, too time consuming.
Diagnosis is time consuming and requires a lot of specialized test equipment, get the idea? $$$
Unless Lexus comes out with a TSB your stuck with the issue or you might try and find a shop that specializes in diagnosis. They will only tell you what wrong and usually don't do repairs themselves.
Good luck.

Dealer had the car for a few hours yesterday and couldn't find a problem with it. They did test drive it with equipment hooked up to it and said everything was fine with no codes. They did inform Lexus so maybe if they get more reports they will look into it. No happy but I understand and will just live with it until it gets worse or Lexus comes out with a fix.
