NHTSA Complaint #11439582 — 2018 BMW X5

My 2018 x5 had the rear driver side air bag suspension give out where makes the ride very bouncy and hard pound on the uneven roads where makes you lose control of the vehicle and possibly have an incident. Came across a few more X5 owners with the same issue and hasn’t been a recall for these years 14-18. Suspension air seems to just give out under 60,000 miles on many people I have talk to along with the dealership confirming this has been an issue with the X5 air suspension system, but no recall or fix of the issue. Please fix and change this part.I’m sure BMW is aware, but need to address before they are more accidents due to this.
