2024 hesitates when cold

[avere3]

I have a 2024 Gladiator Willys (3.6, auto) with about 35,500 miles. I've owned it since new. I had an oil change at ~35,200 miles last Saturday. Other than new tires in the stock size, it hasn't needed anything replaced yet. Minor mods include a steel skidplate under the bumper, winch, and step bars at the corners of the bed. So nothing that should affect drivability.

Last Sunday, the weather was starting to cool off a bit. I backed out of the driveway then drove forward a couple hundred feet to the stop sign and the main road. When I hit the gas to turn left onto the main road, it felt like I was towing a heavy trailer or like it was about to stall. I pushed harder on the gas, and it suddenly took off. This morning, it was cool again. I did the same thing, and it hesitated again when I hit the gas to take off. I started to push the gas harder, but traffic was coming on my right side, so I stopped, backed up, and waited. This time the throttle response seemed normal. I think it did the same thing a couple times last winter.

The part that concerns me is I owned 3 Dodges from 1998 to 2008, and ALL of them had issues like this. My '96 Neon acted like it was going to stall when I pulled out of the driveway, much like the Gladiator is doing, except weather didn't seem to matter. My '97 Stratus would stutter when backing up from a parking spot unless the wheels were perfectly straight. My '01 Stratus must have been abused by a previous owner because it had the Autostick. At low speeds in heavy traffic, I had to shift it manually to keep it from slamming into gear. You would think that this wouldn't be a consistent problem after all these years...

Now before you say it's user error, my '08 Versa, '16 Colorado, and even my '89 Sierra never had any problems, and I've never had this issue in anyone else's vehicles I've driven. My '12 Rogue did this twice, but it had a CVT that was having issues, and I traded it after it nearly caused an accident.

I should still be under warranty, so I'll probably call the dealership tomorrow, but I don't expect them to experience the issue since it only occurs when it has sat overnight.

Have any of you had a similar problem? If so, was anyone able to diagnose it and correct the issue?

My 25 does it. Pretty much everyday and it has since new. Just figured figured it was a modern car thing.

Most jeeps have that dead spot. They make a pedal commander thing that can correct it but other than that it’s how the 3.6 does.

Yup….. 2024 Mojave here with only 21,000 miles…and it happens almost every time I get in it. Sometimes worse than others…… and usually in the initial few miles of driving (regardless of how hot/cold it is outside).

I just figured it had to do with the throttle-by-wire or whatever Jeep calls it.
I often wondered if you can RE-Calibrate the gas pedal or whatever else is involved.

My previous 2016 Canyon had a somewhat similar issue (google search ’chuggle stutter’). I honestly believe that was a ‘programming’ problem on the 6 speeds. I could put it in tow/haul mode and not have the issue.

I actually owned a Pedal Commander for a while on the Canyon…. worked as intended. Long story short, I eventually took it off and learned to push my foot down harder.

It's likely attributed to the garbage computer tuning these come with factory. Mine also drives like ass under light throttle below fourth gear. I have found if I drive it aggressively it 'helps' but normal driving its less than great. Then you get to just the right place where you slap the pedal down and the truck simply doesn't know how to react and waits 30 days to drop a gear and throw the fuel.

From what I understand, Brad's tune fixes (among other things) all the goofy EGR and variable valve lift crap going on at low RPM / low speed that makes act funky.

In short - there appears to be no reason to keep tolerating it IF you have a little money to spend.

Keep in mind, Jeep in no way had performance or perfect drivability in mind when tuning this thing. It had to be close enough and hit a fuel mileage figure.

Banks works great in the Gladiator.

I had a similar concern about my 24 in my thread here, https://www.jeepgladiatorforum.com/forum/threads/rough-idle-when-partially-warmed-up.112347

Posting this as some of the replies might be helpful to you.

That sounds similar to the Canyon. The worst part of it was after making a turn. You’d step on the gas normally to accelerate and it would stutter/chuggle.
It would never downshift until you stomped on the gas. HELLO? WAKE UP!!!

I was still under warranty at the time. Dealership did transmission programming changes & replaced my torque converter. All that worked great for a couple months….then, it‘d come back. The Canyon (6speed) had this thing called “Adaptive Learning” where it would learn your driving habits and adjust the shift points accordingly (hence, why I believe the issue came back later on). Never did get that problem fixed…I just learned to stomp on the gas harder. I traded it in for the JT.

The Canyon 8speed transmissions had similar issues and they blamed it on the wrong ‘oil’ in the transmission. I still swear, it was programming.

I'm not certain on the GM 8 speeds, but the 6 speeds had some strange transmission tuning. I have already fixed some of it in my Camaro 6 speed, like not allowing the torque converter to slip even when locked - which makes the converter fail prematurely. I wouldn't doubt if they did it in the 8 speeds too. I have it set to lock properly now

They tend to tune transmissions for comfortable shifts and good NVH and not so much longevity.
