So it looks like an Automatic JL has some issues with steep climbs. It cuts out like going into limp mode. Here is a video.


HEY
I know it's been a long time since you uploaded this post
Can you update what you did about it
Has Jeep released an update on the subject?
For me, the engine shuts off while climbing, even when I am in manual mode

Thanks

Is this happening on all JLs or just some. I just saw it questioned on a FB group. Also curious if there has been a fix or if this is something i should be prepared for.

What year is your JL and what degree grade when this is occurring.

The only fix I’ve heard of is doing hills like this in “manual mode”.

Happened to me last night.
Guess it's still a "feature"

Was surprised, as coming from a manual I'd never experienced this issue.

I tried to recreate and see if it was something like a loss of oil pressure, but pressure reads 29-30 entire time....

I got into a situation like that a while ago, I'm pretty sure it was the BLD that was cutting power and it really screwed me over. I was trying to climb up a steep muddy hill and the terrain was extremely sloppy and it was raining:

Every time we got close to getting over the top, the BLD would kick in trying to do its thing but that would cut power and slow our momentum at the worst time when the hill was at its steepest. This was in 4L which has traction and stability control disabled. I kept reversing down and coming back with more speed and right at the worst time it would feel like stability control was cutting power (but its really the BLD 'stability control') and kill the momentum when we needed it. Backing down the hill and trying more and more gas was to no avail, it kept killing the power right when I needed it even though I was applying steady throttle and you could hear the brakes crunching/modulating.

I had to stack stones and branches for a good hour to get up the mud hill, but I would of been able to make it if the Jeep wasn't cutting power when I needed it in the mud. This is definitely a situation that I would of benefited from having lockers. I know the photo doesn't look like much, but trust me it was steep and the mud was almost up to the frame. I'm pretty sure this isn't just an automatic issue since manual Jeeps have BLD, but mine is an auto so I can't say.
