    I feel the gas pedal is too soft, have to lift my foot, make my leg not comfortable.
    My 2001 Accord and 2005 GX470 don't have this issue.
    Can the firmness be adjusted?

    I don't believe that you can adjust the firmness, but you can adjust the throttle response: Eco mode for least sensitivity, Normal mode for middle, and Power mode for most sensitivity. That might help it feel firmer if you don't have to depress it as much for a given amount of acceleration.

    No. No "standard" way at least.

    But are you sure that you don't mean the pedal it too STIFF ??

    I have the same problem (too soft, not stiff). Very uncomfortable keeping foot slightly lifted. I would think fixing this would only require a tighter spring. I'll ask my dealer about this at next service.

    Newer cars all seem to be soft. Just the weight of your foot pushes it. Lol
    More feedback, resistance would be nice.

    You’re welcome to ask, of course, and there is a spring, but the Repair Manual (more info) warns, “Do not disassemble the accelerator pedal sensor assembly.” If defective, it’s replaced as a unit. Considering Toyota’s history of unintended acceleration issues, I’d be surprised if any dealer would be willing to attempt internal repairs or adjustments not described in Toyota’s publications.

    The pedal isn't intended to support the weight of your foot. But I have had a couple that were too stiff. If you find the place you want for the throttle, you just rest your heel on the floor and the side of your toe against the "hump" and let that do the supporting. It should require zero effort except to change speeds.

    I think I'm missing something here. Could those who are talking about a lifted foot explain more. We are all doing it like this, right?

    With my other cars, if I want to keep the speed at, for example 45 mph, I just rest my foot on the pedal almost without any effort.
    But with Prime, I have to lift my foot and hold that position. Otherwise, the speed maybe go to 70 mph.
    I used my hand to feel the pedal, it is softer than my GX470.

    I'm curious about that too. I have always rested my heel on the floor on all my cars and I have a small foot for a man...

    I do rest my heel on the floor, but have to use a little effort to lift foot palm on the pedal, and hold that position

    I can see how that might be a problem if you have your seat so far forward that your knees are up in the air and the seat isn't supporting the bottoms of your thighs. That would put downward force on your ankle which would lever down on the throttle. But in a proper position, your foot should be able to relax with the friction of the carpet on the side of your foot being sufficient to hold it in position. I have friends who sit super close and it's kind of scary because it puts them too close to the steering wheel also.

    I assume the gas is electric, not wire, I'd get a real sponge, rectangular, biggie. Velvro one end and stick it on the floor under the gas pedal, lot's of natural resistance.

    Or adjust the seat?
    Lower or raise it to get an angle that gives more blood flow to the foot.

    I recommend a higher seat cushion and to adjust the angle your foot rests on the pedal.

    I honestly do not like the seating, especially for long drives but my seat cushion helps a ton. The seating is probably my biggest dislike.

    Otherwise a good car and I use the cruise control a lot to help with not having my foot on the pedals all the time.

    Maybe you just need different shoes.
    Or you need to adjust your seat forward or back.

    I STILL do not understand why any part of your foot would need to be "lifted".......IF you are positioned right.

    OK I think I understand now. You aren't lifting your foot off the floor (which is what a lot of us on this thread were visualizing). Rather you are having to pull back the ball of your foot to reduce allerceration and maintain speed, leaving for foot/leg in an uncomfortable position.

    Does this correctly describe what is going on? If so, I'd reiterate previous advice: try eco mode so that you can depress the pedal further for a given amount of acceleration; adjust your seat position or height; try some different shoes.

    Personally I haven't had this problem. My bigger annoyance is that you need to maintain some pressure on the pedal to coast and avoid regen. Gets somewhat tiring around hour 2 or 3 of a road trip. Great feature in most cases--not as much on long trips.
