when i come out in the morming togo to work the car is squatting to the bottom with no air at all in the suspension. it fills right back up again when i start the car.
Sagging rear suspension, truck looks like a low rider. Air compressor comes on and lifts it back up but now it's not lifting with the compressor. What could this be
It does fill up as soon as i start it immediately fills. just wondering if it may be an early indication of a problem
Rear End sags when the vehicle is shut off. Reinflates once vehicle is started. Is this an indication of a bigger issue.
SUV is sitting from night before with rear on the floor. Start it up and it inflates.
Park it in the garage at night and Rinse & Repeat... Every day...
Every time I stop the vehicle and let it sit for even a few minutes my suspension deflates. I have also had it happen while I was driving and have had to pull over and turn vehicle off and on several times to get it to re-inflate.
When I turn the car off the tail goes down, sometimes it gets lower than before. Then when you start the car it jerks as it pumps itself back to normal height from the ground. I reached out to the dealer and the guy explained that he has heard of this and it's due to the fluid in the air bags that sits on top of the compressor; it's really weird. But the fluid is leaking inside the air bag even though you do not see it leaking. He called it wear and tear and it costs about $1,500 to repair. Yikes.
Car goes low to the ground when stopped. Used to raise up when ignition started but no longer goes up.
