I have a 2012 JGC Overland and I am having issues with my Quadra-Lift. I have had the usual list of issues with the QL as others have posted but recently I am unable to lower the vehicle below OR1 or raise it higher. I have not seen any anyone comment on this elsewhere on the forum. Whether I adjust manually or let the Jeep do it, all I get is the yellow symbol on the EVIC that indicates that it is lowering, but the height does not change and then shortly after I get the EVIC message to take it in for servicing. At the same time I can hear the compressor working as it tries to adjust the vehicle so perhaps it is not a compressor issue.
Anyone else had this issue? I am going to take the wheels off and look at the sensors to see if perhaps the annual undercoating has gotten in there and jambed things up. Any issues if I unplug the sensors?
Been to the dealer, apparently the problem is caused by the the two front strut pressure relief valves. Parts are on order and it will be about $1,000 to fix. Hopefully this solves this. Thanks for the advice.
