Especially if you are out in the wilderness and you loose an air spring or all the air leaks out.

So is filling it back up a "do-it-yourself" job? Should we all be carrying around a can of nitrogen in the trunk just in case? I don't like the fact that if we get a slow leak, the pump can't pressurize the system with outside air.

Re: How about reliability of QL(air suspension)

I really do not think it is a DIY.

Read all the warnings:

WARNING: All pressurized air suspension components contain high pressure air (up to 220 psig). Use extreme caution when inspecting for leaks. Wear safety goggles and adequate protective clothing when inspecting or servicing the air suspension system. A sudden release of air under this amount of pressure can cause personal injury or death.
WARNING: Support the vehicle by supplemental means before performing any work on the air suspension system to prevent the vehicle from changing height. Before any given component is to be serviced it must be deflated. Servicing the air suspension system without supplemental support, or with pressure in the specific component, can cause personal injury or death.

Re: How about reliability of QL(air suspension)

Certainly not a DIY job.
It obviously requires special tools and Starscan.

And the common Nitrogen used for inflating tires is not of the high standard (Class 5) required for the system.


On the plus side, it is quite likely that the system, being fully sealed, will have a longer service life than other, more common, "open to atmosphere systems", if by only because the closed loop systems use Nitrogen, not humid atmosphere, limiting degradation of valves and seals from water ingress.

Regardless, all of these systems are a nightmare when it all goes wrong, and it's not something I'd cherish out of the warranty period!

All the more reason to spend an extra $1900 for the LIFETIME warranty. Problem solved.

Do the dealers offer any sort of extended warranty? Seems like it would be good business.
