We traded our 2010 4_Runner (no problems) in for a 2015. Biggest mistake we ever made. Toyota has gone so far down in quality they've actually gone into the "danger" zone.
The pedal has a terrible lag in the acceleration. Which mean often when we put the pedal down to accelerate, the car just sits there and then zooms off in a jack-rabbit rush. This incident I just had is no kidding: Coming home, I felt the lag so I put the pedal to the metal to test it and the car just sat there like it was in idle. I held it there to see how it would take for the acceleration to finally kick in and it never did. I sat there for 5 seconds literally with the pedal to the floor and the car didn't budge.
We've taken the car to the dealership. After what they tried to make us believe were "exhaustive tests" keeping the car overnight they finally concluded there was nothing wrong with the pedal and nothing they could do. I showed them print-outs of 4-Runner forums where literally dozens and dozens of people have complained about the same problem. They just shrugged and said they could find anything wrong with the car.
Beware buying a new 4_Runner. This is literally a life-threatening situation. If you have a 4-Runner already you know about this. The only thing to do when the engine lags is to immediately take your foot off the pedal and then reapply your foot pressure to the pedal.
It may be the way it was deigned or a bug in the engine management software (or the one that controls transmission). In both cases the dealer can't really do anything practical. The solution should come from Toyota. Why not contact them directly?
This is not how a 4runner operates, I have one (a 2015) and it does just fine, and a friend has one (also a 2015) and it does just fine, and I am a member of a club with a few 2015's, and they all do just fine.
This is a very rare problem, to the point I have never heard of it and it does not come up on a search that I have done.
Please show on the 4 runner forums where "dozens and dozens" of people are complaining, I am very active on the 4 runner forums and never heard of this complaint.
I've had a 14' Trail Premium for a year and a half and have never encountered a problem with mashing the pedal and the car not responding. I will admit that, compared to my old 06' V8, the 5th Gens are slow turds and you do have to dip into the throttle quite a bit to wake up the engine.

The 0-60 times are like a half of a second different (depending on your source), so it is not that much of a difference at all.
There are no issues of the lag the OP described, I have looked extensively for it and have not came across it, so if true, the OP has a unique problem, there certainly are not "dozens and dozens" of pages on 4runner forums of people complaining about it.
Those vehicles have drive by wire system. Accelerator and brake pedals have no connection to actual parts they are supposed to operate. Brake pedal has what is called "stroke simulator" pretty much faking pedal resistance for the driver psychological comfort. Gas pedal has pedal position sensor that simply tells ECM what level of acceleration operator desires. Then all kinds of electronics and algorithms kick in and servos produce desired effect.
System may result in rather strange effects. In my 07 TCH, going up hill from halt is rather and adventure. For about 2 seconds, you have to let go off the brake pedal, press the gas pedal - and nothing happens. She does not roll back or move, THEN she takes off.
OP, why don't you try driving same model/year but a different vehicle, and see, if it's maybe operator fault?
I'm trying to figure out why you would trade a perfectly good 2014 4Runner for one model year newer?
Op said it was a 2010. I have no idea why someone would trade a perfectly good 2010 for one 5 years newer without any major changes.
