Re: Quadra-Lift Reliability

I use the QL every day. In city traffic I will go to the raised position to be sure my trailer hitch is even more visible to the person behind me. When I go in the parking garage which is so low I can barely stand in it (I'm 6'3") I have the vehicle squat down to the park position. Driving otherwise is either in normal, sport or aero depending upon traffic, speed, my mood, etc. No problems whatsoever.

Re: Quadra-Lift Reliability

As a follow up, my Jeep is still at the dealer, now day 12. The air suspesion does have a leak but every test has been negative. Sitting overnight the pressures in the reservoir tank does fall. They say they are still talking with engineering at Chrysler but still no solution. The wait continues....

I have no idea how difficult it is to do, but I would disconnect the rear lines and bags and plug them and see if it pressure drops overnight. Then I would do the same for the front lines and bags. Seems as though it could be isolated a little.

Hope you have an extended warranty or is that covered by the drive train warranty?

Apparently there is a protocol for testing various aspects of the system for leaks each taking a 3 hour cycle. If I still have it beyond the warranty, one thought is to have the nitrogen tank checked/topped up at oil change visits.

Re: Quadra-Lift Reliability

On my 2011 JGCO I use the QL daily ... I like switching it up from sport to OR2 sometimes I raise just to park next to a competitors vehicle and I want mine to be taller LOL! No issues other than it seems to develop a grown over bumps when its REALLY cold like below zero cold. It goes away when it warms back up.

Re: Quadra-Lift Reliability

Well, I got the call from the dealer finally. They have found the leak. It's a valve within the front lines that leaks with extreme cold weather. That seems logical since one year ago, January, I had the same problem. The bad news is that it will take 3-5 days to get new lines from Detroit and a bad snow storm is arriving tomorrow night. I've been depending on my summer car (Porsche) for the last two weeks and they have offered a rental which I had declined but will rethink.
I'm just happy they found the problem and it wasn't for not trying. In this case, the weather had to be cold enough for it to recur. My dealer has been very good to me and I sure miss my Jeep.
