its not that bad! - its usually sob stories of people who either bought a car they couldnt afford or were contacting useless workshops to diagnose it. Air suspension is not new, millions of buses and trucks worldwide use this tech and are good.
In passenger vehicles its a bit delicate compared to heavy duty stuff - but its fixable, Its fun to see someone who bought an S class benz - and is now facing repair cost of replacing air struts or air springs.
LOL,, they literally poop their pants.
