Re: Quadra Lift Problem??

If its trying to get to OR2 but can't you most likely either have a bad compressor or its low on nitrogen. I had the exact same thing happen when I first got mine its couldn't get to OR2 and it was a bad compressor. When was yours built?

Hi jp467, it sure is great to see you pop up! I've been reading through some threads on the subject, and appreciate yours and everyone else's input.

Anyway, it was built 6/11. I actually stopped in at the dealer early this morning but they said the right person wouldn't be in until Tuesday. The service manager said he'd seen it before. Though he didn't know what the problem was, he said it was ultimately fixed. I'm going to bring your suggestions to them. Sounds like if it's the compressor, I'll have to wait to have it ordered.

I sure hope I don't have to go through some of the headaches some others went through. But I'm not jaded yet. I love the car and it's riding level and in the appropriate normal position. Can't wait to get everything working as advertised. Seems like it's common, but also commonly fixed. I'm optimistic thanks to the forum!

Edit: Oh, it may also be worth noting that it's made it into OR 2 before, but just once at the dealer and not since.

Re: Quadra Lift Problem??

I think it will be an easy fix. They might have to order a compressor. It seems like all of the problems with QL are right out of the box. I had the bad compressor problem and have not had any more problems with it since and its been six months. Keep us posted on what happens.

Re: Quadra Lift Problem??

I had my compressor replaced about 2 months ago and am now having the same problem again (it won't go into ORI or ORII). I was prompted to check it out when I noticed that the compressor was making frequent hissing sounds (which was the telltale sign last time this happened).

I'm starting to get disillusioned with my Overland . . .

Maybe the techs at my dealer aren't well trained, but replacing my compressor was not an easy fix for them. In addition to taking nearly a business week to fix (in fairness, they got me a loaner for the last 2 days), they dug around the interior so carelessly (I assume because they were trying to figure out what to do) that they scratched the back of my driver seat and the plastic rear of the passenger seat sags at the top.

I can only guess that the compressor is located under the rear seats, because that's where most of the grease and grime was left behind (yup, they didn't even clean up after themselves before delivering the "fixed" vehicle back to me). Additionally, they dropped something heavy and sharp on the door sill which left a dent and scratch.

When I expressed my concerns to the service manager and showed him the damage, he cleaned the interior with a solvent and said he could have their body shop repair the door sill. However, that would mean another couple of day's downtime.

Of course, now my truck is a rattle trap (undoubtedly because of all the digging the techs did inside) and I'm wary of baring the inevitable inconvenience and frustration invariably associated with having them identify and fix the noise.

To add insult to injury, the service manager had the tech come out to 'tell me what Jeep told him'. This amounted to him relaying to me that if I rapidly or frequently raised and lowered the suspension, it could burn out the compressor. Thinking of this 'blame the customer' meme still incenses me to this day. Particularly in light of the fact that I'm not some kid unfamiliar with having a car of this caliber who abusively plays with its features . Further to that, this tech is presumbaly the same jerk who abused my car. It was shocking that these folks had the audacity to point the finger at me.

Needless to say, I'm very unhappy to be facing the prospect of another "easy fix". . .

Re: Quadra Lift Problem??

Might be time to change your dealer. None of that is acceptable.

Re: Quadra Lift Problem??

The compressor is located in front of the front right wheel and behind the front bumper. The control module for the air suspension is under the drivers seat. To replace the compressor they need to remove the right front wheel the inner splash shield and the front bumper cover. When I was having the problem it was never at dealer overnight. I took it in they had not had the problem before so they called chrysler and went through the troubleshooting found it to be a bad compressor. I picked it up and took it back a week later when the compressor came in and it was replaced and I had it back the same day.

My jeep just started having this exact issue. Jeep takes forever to reach OR1 (if it even does) and will never make the OR2 height. Anyone have some advice on how to pursue this with the dealer?

It is a huge pain that Jeep doesn't offer loaners.

STIX, what was the final resolution of your issue?

Re: Quadra Lift Problem??

Low nitrogen or bad compressor........or both. If it is low on nitrogen and keeps pumping, you will end up with a bad comressor eventually. I just had mine repaired and it had 80 psi on nitrogen and should show 165 to 170 per the tech, however it is measured (assuming psi). They told me there is no set procedure to find a leak, just the old soapy water trick. If true, that is high tech for such a complicated system. Hopefully, it was low from the factory because mine was always slow from the start and they just now checked the nitrogen level. Low nitrogen is one of the major causes for systems overheating I'm told. This is a learn as you go process but hopefully things are getting sorted out. (I think). Mine is fine now.....we will see.

How did it ride with only 80 psi? Thats only half of whats required was it sitting kind of low? I was under the impression that the ride height is controlled by pressure so with it being so low it must have stayed down near park mode. You also don't want any moisture in the system this will also ruin the compressor. You want to make sure they are using class 5 nitrogen.

Re: Quadra Lift Problem??

Ride seemed to be fine. The best it would do for height (stock tires) was 34 1/2 inches and now it goes up to 36 inches (measured middle of front wheel well opening bottom edge down through center cap to floor). Much faster of course, better than new.
