Post Quadra Lift Dumping Air When Beached

I have been persisting with an issue for a while now that I expereience in my 2014 Overland.

The issue is when the body bottoms out and the Jeep gets stuck, it appears that the Quadra Lift system attempts to compensate for the increased suspension height by releasing air from the rear air springs. This has the unfortunate effect of making me more stuck.

What I would like to know is if anyone can confirm getting stuck in a model newer than the 2014 and did not have the suspension drop at the rear.

In the mean time, i am popping the fuse out when i expect I will be getting stuck.

Thanks,
Daniel

After a certain speed the airlift lowers by itself, is it lowing because your spinning the tires to fast?

No, it's not because of spinning the tyres too fast. The buttons become unresponsive. After driving a few hundred metres, the suspension fixes itself.

Good point, about the speed though. ORII lowers to ORI when you exceed 20 mph (32 KPH). The buttons will be unresponsive at this time, because you are at a speed which will not allow it to switch to the selected ride height. Once the speed is at or below the limit you can go back to that height.

There are 3 fixes for this issue you're having though, regardless if it's the speed or just a travel limit due high centering it as you mention experiencing. The first option is quite simple.
1. Pull the fuse as you mentioned
2. Go to the settings menu and select "Jack Mode". This disables the auto level system so it won't change on you.
3. Install new custom length links. I made a set that are adjusted for ORI but you could make/buy a set adjusted for ORII. With the links you are making the sensors think they are in "Normal" height even though the suspension is in a different setting. In this configuration the speed won't be an issue, and the sensors shouldn't adjust when you high center since they think you have plenty of room to move.
I would caution though, that with option #3 you want to be mindful to not over-travel the suspension. I assume there is a physical limiter but something you'll want to keep in mind if you go that route.
