2015 Summit Suspension problems

This is our third Grand Cherokee (1994, 2006, 2016), and 1 Liberty
Rather frustrated less than 9000 miles on the Summit 4x4, v6 and in the dealer a 3rd time for suspension problems.
--- Does anyone have any additional information how this problem can be fixed?
Back checked, this the system lifted from Mercedes which also have the same issue
My deal cannot find any leaks or or loose connections similar to Mercedes issues
The Mercedes shop bulletin states to:
Replace the sensors
Replace the sensors and the controller
Replace the sensors, the controller, and the compressor and related connectors
A lot of trouble shooting. these are faulty system systems and should never be put into vehicles

Looks like I am left to go through months of trips to the dealer and a possible lemon vehicle scenario or trade it on something else
Help

Re: 2015 Summit Suspension problems

Had similar suspension issues! Dealer replaced the controller and compressor and all has been good for the last year. Hope it works out for you.

Could you be a little more specific as to what the problem is?

2015 Summit Suspension problems

I have no idea how your problem can be fixed because you never stated what your problem is...

Re: 2015 Summit Suspension problems

Hi
The problems are the vehicle cycles the compressor while the ignition is off, been told this could be normal??. The suspension will start to loose nitrogen in the closed loop. At this time the suspension will stiffen up and go to off-road 1 mode for several days, after which the suspension will completely lower. With condition can be hazardous while driving.

Sounds like you have a leak - probably time to find a good dealer/service dept., and have them check it out.

Re: 2015 Summit Suspension problems

Yes, it is normal for the compressor to run periodically with the ignition off. However, it should only correct for slight differences in height from tire to tire, not switch to a different mode. You likely have a small leak that could be anywhere. I'm sure the dealer only checked the line connection points (at the bags/compressor) but a leak could be anywhere in the system.

Re: 2015 Summit Suspension problems

Twice this week, when I've started my vehicle in the morning it has been in off road 1. I know for sure that I didn't bump the button. So does that mean I have a small leak?

Off hand, I'd say yes. I've never had mine adjust after being off for while. You may have a slow leak in the system I'm guessing ...
