The failure pattern owners describe
Owners of this 2008 R-Class report the air suspension system failing without warning, causing the vehicle to sag, lean to one side, or drop to the ground. Several describe the car settling low and tilting to the right rear or leaning to the passenger side. One owner's vehicle sagged so severely it couldn't be driven and required towing. Another reports the air bags "blew up" while driving.
The failure happens across a range of mileages—43,000 to 132,000 miles—with no consistent warning. Some owners note the "car rising" indicator illuminates but the vehicle won't actually rise. One owner replaced the right air bag and had to replace the left one six months later. Air suspension damage with visible holes is also cited.
A few owners mention contacting dealerships, discovering there are suspension-related recalls but encountering unclear or conflicting information about whether their vehicle qualifies. One owner purchased aftermarket air bags from a third-party supplier that failed and weren't honored under warranty. Owners express frustration that this appears to be a widespread, known issue without a full recall in place."
