I have been dealing with a dealer since February on Air Suspension issue. It get's stuck in Aero Mode - when slowing down or at a stop sign it won't lower to normal ride height. Get an error to "service air suspension immediately". You have to shut the truck off and turn it back on to get it to lower. I can raise and lower it using the buttons inside the truck so I know the compressor is working. Dealer stated it was a sensor $300. Didn't fix it. Stated it was the other sensor $300. Didn't fix it. Put on a new compressor at $900 said it wasn't inflating the air bags properly. Didn't fix it. Now the compressor runs continuously and has an air overflow that you can hear let air out. It also is riding so low on the bump stops. I am not paying them $2,000 for parts that did not fix the "aero mode" issue. Has anyone ran into this? They are trying to figure out what they should do next. I couldn't be more frustrated. Anyone have any advice for me?
