So my 2010 Chevy Avalanche LTZ autoride compressor would activate when I started the vehicle, after about two months or so I noticed the rear end of my Avy had a slight sag to it. After further investigation I realized that my compressor was no longer kicking on when I started the vehicle, nor when weight lowered the rear suspension. So I looked underneath the truck where the compressor is and saw what I would describe as a corroded mess. I took it to the dealer as was told that if I had no DIC messages stating "Service Autoride" not to be concerned because the compressor is "really quiet".
Well after about another month I researched that the compressors are "highly likely to corrode" due to their location under the fender well in direct travel of tire sling. An OEM compressor will not throw codes if the ride sensor is not working but still has it's proper voltage. I climbed under the truck again to realize my rear air shocks were not inflated even though the vehicle was running.
I returned back to Chevy dealer and they want about $1500 dollars to replace the shocks and compressor. Of course I am out of warranty and can get no help from CHEVY although this is a common issue on their high end vehicles.
