    Hello,
    The 2011 has been Giving the “service air suspension immediately” warning off and on lately, when it’s not having a bad day everything works as it should, it raises And drops, sounds normal etc... this morning on my wife’s way to work it said “reduce speed for suspension setting” she was in auto mode like always and going 50mph...
    What could be causing this?

    Update, when started this morning it says it was in park mode setting, we definitely didn’t put it in park mode when we shut it off last night, would it do this automatically and I just haven’t noticed it before? I’ve only owned this jeep for two weeks so that’s possible I suppose, if not and I had a leak wouldn’t all four sides have to be leaking for it to go all the way to park mode level? I’m stumped. Yesterday it told my wife to reduce speed for the mode she selected, which she didn’t select anything, she keeps it in auto and never messes with ANY of the settings at all... just starts it up and drives.

    Early this morning I went out and started the Jeep, it said normal ride height or something to that degree... but it is not normal, lol, the front is still low. Found the fuse was blown for the air ride, makes sense because I haven’t heard the compressor working in the last couple days and the front has been down, maybe a leak in the front overworked the compressor and blew the fuse?

    Do you believe your issue may be related to the TIPM and bypass on the fuel pump relay?

    Just had it towed to the mechanic last nite... he just called and said the air compressor has a crack in the rear☹️, after that I’m guessing air line leaks as well , but who knows... what a bummer!

    The compressor had a crack in it, replaced with another one, and the new one doesn’t seem to build enough pressure, the mechanic said he could hold is thumb over the hose and it didn’t have enough pressure to blow his thumb off. Would a broken compressor cause the Jeep to go all the way down front and rear?

    That should explain the "service the air suspension" issue as the compressor can't pump to the specified pressure requirements of the air suspension. Hopefully another pump will fix it as well as any leaky connections or lines

    So it’s at the dealer now, They charged the system up with nitrogen and they can’t find any leaks but the compressor still won’t shut off it just keeps running, so they want another hour to diagnose that problem so I gave them the go ahead.Maybe a relay? Hopefully something simple because this is getting expensive

    Just talk to the service department at the dealer, the jeep is now all the way up but they can’t get it to deflate, he took the technician off the job for a little bit because he was getting real frustrated and wanted to give him a moment to calm down. He said something like “he tells the computer to do one thing and it won’t or it does the opposite”? Getting pretty nervous.

    They still can’t get the jeep to lower, it is however holding all the air, they tell me they think it is the control module which is stupid expensive, any ideas where I can find one reasonable other than from Chrysler?
