I found this pretty interesting. Left is QX80 with 120k miles. Right is QX80 with 120 miles. Both cars parked at the same time about 24 hours ago.
Left lost all air pressure and it is sitting on coil springs. Its getting worse over several months. When I start the car it comes back to its proud, muscular stance but after 24 hours looks weak again.
Pretty easy to see the air suspension is ready for replacement. I already knew that and priced all in. $500 for 2 OEM shocks with miscellaneous hardware (always replace mounts at the same time), $450 for compressor (if OEM) or $250 (if cheap Ebay one).
And one note for those with less miles. Most of the time it is the compressor that fails first. I talked to technicians and they said this is the most common problem. So if you have this problem and shocks are not ready for replacement start with that. Mine has 120k miles and shocks are still in great shape. However shocks are designed to 100k miles and probably sooner than later the rubber airbag that continuously roll up and down as you drive will develop microcracks that will seep air.
I plan on doing this all in the spring so will post few tips...

my poor truck but there wasn’t any codes visible on the dash. Soo, I took my generic Blue Driver Bluetooth obdll tool hooked it up had a code for ride height sensor, so I cleared it, and crawled under the truck started back probing the sensor, and yes it was getting signal power and ground after the connected, I unhooked the arm at the ball and slowly moved it, it started at like 4.7 volts and I could raise it all the up and it would start to go down but then climb back to 4.7 so yea it’s shot. So I order a cheap one off amazon 50 bucks pacewalker. Now I don’t know the procedure of replacing the sensor I just crawled under took the own off put the generic on plugged it in, oh yea I did unhook the negative battery terminal hooked it all back up wouldn’t come on the air compressor so after much research I bought the diagvcx nano for Nissan/ Infiniti and installed consult 3 plus v240.10 and that’s where I’m at now
