Intermittent Grinding in the Gas Pedal

I have a 2021 Bighorn Night Edition with the 5.7 etorque motor. I have about 4K miles on it and have had it for a little less than 2 months.

I have noticed a grinding in the gas pedal at random times. It is very quick and short and it seems to be very random, I dont think I could replicate it for the dealer. The 'grinding' feels a lot like ABS when engaged. Has anyone else had this issue? Is it a problem?

I sometimes feel a vibration in the gas pedal when I'm driving shortly after startup on hot days when the a/c is pumping. Seems to go away after a few minutes.

I’ve felt this grinding 3 times since I had the truck, with just under 6k miles now. Mine has happened under moderate acceleration. But very random and only happens for a few seconds, if that. You and I have identical match in truck. I wasnt too worried about the eTorque system when I first got it, but after reading a lot of stuff on this forum, it’s on my radar as something suspect.

I still have this issue, I think the pedal may be grinding in mine when it is shifting into another gear. It happens so infrequently that I cant pay attention to it, so idk. Because it is so sporadic, I think calling the dealer is kind of a waste of time, but now that I know someone else is having the same issue, maybe it is something common that they know about. I will give them a call and see what they say. I'll keep you posted.

I was pretty excited about the etorque when I got the truck. I didnt specifically ask for it or anything, it was just the only night edition I could find so I bought it. But after a few months driving and trailering things, I dont really see the benefit. Seems like something that just complicates things that will make repairs more expensive down the road. Also, I believe we have a lithium battery (I could be wrong on that) but if that goes out, I would think that would be about a grand to replace. I think I would opt out of the etorque if I were to do it again.

I was in the same boat with the ET. I was focusing more on the night package I wanted. My wife's car has the start/stop and I wasn't really a fan of it, but it hasnt given us any issues in the 2 years since she got it. I've acclimated to the ET by now, just not 100% trusting of it yet since I have never owned a vehicle like this. I agree, I think the replacement for it down the road might be pricey. But I have heard in other threads there is an 8yr/80k warranty on the Etorque system, which is longer than I plan to have the truck. So at least in that time if anything with the ET goes, it should be covered under warranty. Challenge is finding a dealer who won't hassle you about it.

Along with the normal 12v battery in the engine bay, there is a 48v lithium-ion battery behind the rear seat (driver side). They can and do go out (my daughter had hers replaced 3 weeks after she bought it new), but so far there doesn't seem to have been a lot of failures reported.

That is good to know. Now I have to go out to my truck at lunch and look for the lithium battery.

I also have this grinding feeling in my gas pedal. It usually happens within a few minutes of starting and driving the truck. I do not have etorque. It happens so quick and is so random I have no idea what it could be. Seems to only happen a few times a week, not every drive. Could it be some sort of adjustment the truck is making?

I am also experiencing this issue, im at 15K Kilometeres 2020 bighorn 5.7L NO etorque
it happens when it shifts from 1st to 2nd it vibrates my pedal for a second.
to be honest it feels like the rear end gear shudder.
ive read post about low differential gear fluid from the factory, could that be the cause?

I am experiencing what the OP describes. The ABS description you mentioned is the same type of pedal feel I experience, only to a lesser extent (its a very vague feeling). Occurs randomly, sometimes on the highway after 2 hours of driving. There would be no way for me to replicate it for the dealer so I'm just making a mental note in case something breaks later.

I also get a weird pulse/vibration in the gas pedal at random times. It's almost like the sound the ABS makes when you first start up and drive and it self-checks, but you can feel it in the pedal. Happens randomly and is quick enough that there's no way to try to listen for any further evidence of the source.

I am the OP, so I will provide a non-update update. I had this problem since I bought the truck new. I now have 30k miles on the truck and I haven't noticed the grinding/abs like vibration for awhile now. That could be because I have quit paying attention to it, or because it is gone. Either way, my truck is still running great and I haven't had any issues related to this whatsoever.

Anyone have an update on this issue? I have a '21 Bighorn (not Night Edition) with 12K miles. Was out on a family trip last weekend and had this occur for the first time. My wife even said she felt it, although very lightly, from the passenger seat....perhaps a vibration through the floor? Very strange and random, as it only occurred twice in 100 miles. I just noticed it once coming back from a 2 mile round trip to a local bank, also. If anyone has an update on the issue, it would be appreciated. Like others have said, there's probably no way I could replicate this to the dealer.
