Rear suspension leak?

[QX_Jean]

My rear suspension won't stay level more than a few hours or just a few minutes when my big travel trailer is attached.

The compressor is working right and the QX leveled up every time I start de car.

I got under the car where the compressor and air lines are and I can't hear no air leak.

Somebody here with the same problem?

Thanks.

what model?

could be a leak in the air bags. most just go aftermarket as its cheaper and offers more options.

2011 QX56.

One airbag ok, but both at the same time?
Both rear bags deflate at the same rate.

if thats the case you have a leak in the piping then. use some soapy water and rub up the couplings and see if you see any bubbles...

Small update. I went to the dealer with my problem. Both air tube from the compressor to the shocks leaks.

They quote me close to 500$ in parts, plus a 3hours job...

So, I bought 20 feets of DOT approved air suspension tubing and will install it myself.

I do have a third party complete warranty but the air tubes are not include...

Other update, the QX air hose are 8mm OD but the 8mm one I bought have an to big ID. There is also a plastic tube that goes inside the hose at either ends that won't fit in aftermarket hose.

So, I guess I will have to buy the oem hoses and tubes assembly. Here in Canada they are crazy expensive but I fount some less expensive from usa dealers.

Hate paying 500$ for leaky hoses....
