I didn’t know there were issues with airbags on the LX570. Why would those be any different than the Land Cruiser?
EDIT: Just realized you’re probably talking about AHC (which is a hydraulic system that supplements the suspension unlike the GX series which has an air suspension). FWIW I hear it’s no problem if it’s maintained correctly, and my 100 series is certainly still trucking along with a great ride quality at 200K miles with AHC, although I’m aware the system is more complex on the 200 series. I personally wish they had it on the LC model for the 200 series, that would be the ultimate 200
