Any Manual Drivers Feel Strange Things?

[multicam]

Hello, I've had my 2019 JL since August, 6500km on it and I have already had to have my clutch replaced. It started smoking one night during a less than 2 min drive. Of course they could not duplicate the problem, and instead tried to claim user error. I have only ever driven manual cars so I know this is not from user error. I've had 7 and only ever replaced 1 clutch after over 300k. I just got it back and now the pedal slams right to the floor when pressed and seemed to come back up in two steps. Any ideas if this is normal? Or what the problem could be. Thanks for any input, this is my first Jeep so not really sure what to expect.

That ain’t normal, take it back to them! Clutch should come up with even pressure the whole time. Only car I’ve ever driven with uneven pressure was a ‘12 Camaro.

That's what I thought, I will be going back to them today Thanks.

I've definitely noticed the rev hang but it's unbearable if I'm accelerating quickly from a stop. It continues to accelerate for about .5 seconds after I take my foot off the gas then RPMs won't drop for another 2 seconds after pressing the clutch pedal. It likes slow shifting with breaks in between.

Yep, that's just how it is. I've found that my Jeep slows down very quickly, so the faster you shift obviously the less time it takes. The faster you are going then the higher the rev in the next gear. I kind of have 2 different "muscle memories" for 1st to 2nd depending on how fast I want to shift. It really isn't the rev hang that kills it, but the huge difference in the 1st and 2nd gear ratios. All modern cars have to have rev hang because of emissions. You are going from 5.13 to 2.63, so its like a 2k rev difference between 1st and 2nd. For reference, in 2017+ Camaros they are 2.66 to 1.78, so can shift faster because there isn't as much of a difference in the revs.

I just found out there’s other gears besides third!

had an issue where my clutch was feeling "sticky", like it was stuck on a piece of gum on the way back up for the first initial inch or so. Took it to dealer 3x and turns out it was a leaking slave/master cylinder and had to be bled a couple times. Feeling finally went away within the next 1000 miles or so.

At 2000 miles I am getting a similar vibration to what others have described here. It's not terrible, but it wasn't there 2 days ago. Seems to be mid range rpm under acceleration. I am just going to keep driving, if it gets worse it's under warranty. Just disappointed to see this may be a common issue.

36k miles. Nothing strange, even after the recall.

If you are feeling strange things in your clutch, turn off hill assist and see if that helps.
