2006 Land Rover Range Rover Sport Suspension Problems

I can be driving and the car will just cut off. The real danger was when I was on the freeway and I almost couldn't pull over to the side and a semi truck was behind me. That happened about 3 years ago. Also when I start the car and put it in reverse the parking brake warning light come on, that also started happening a couple years ago. The above happened again yesterday and the day before, October 9, 2021.

DRIVING ON THE FREEWAY AND MY CAR CAME TO A COMPLETE STOP. THE REAR SUSPENSION DROPPED TO THE GROUND WITH NO WARNING OR NO APPARENT REASON. THEN I FELT MY LEFT TIRE GO FLAT. ONCE CHP AND THE TOW TRUCK GOT ME OFF THE FREEWAY. I NOTICED THAT THE ENTIRE REAR SUSPENSION WAS ON THE GROUND. THE SUSPENSION FAILURE CAUSED BOTH OF MY REAR TIRES TO BUCKLE INWARD CAUSING THE LEFT ONE TO BLOW AND THE RIGHT ON GAUGED OUT ON THE INSIDE. LAND ROVER DEALERSHIP DIAGNOSTIC REPORT SHOWED SUSPENSION FAILURE AND THEY JUST PUSHED A BUTTON TO RAISE IT BACK UP. THEY FIXED ABSOLUTELY NOTHING AND EXPECTED ME TO PAY FOR TWO NEW TIRES AND WANTED TO SEND ME BACK ON THE ROAD. THE MANUFACTURER WAS NO HELP EITHER. I STILL PAY THIS CAR NOTE AND TO DATE HAVE NEVER DRIVEN THIS DEATH TRAP AGAIN. IM A AFRAID IT WILL HAPPEN AGAIN WITHOUT ANY CAUSE OR WARNING. *TR

DT*: THE CONTACT STATED WHILE TRAVELING 30 MPH THE AIR SUSPENSION SYSTEM COLLAPSED, CAUSING TOTAL LOSS OF CONTROL OF THE VEHICLE. IT WAS TOWED TO THE DEALERSHIP, WHERE THE AIR SUSPENSION WAS RECALIBRATED. NINE DAYS LATER, THIS OCCURRED AGAIN WHILE TRAVELING 65 MPH, THE VEHICLE WAS TOWED TO THE DEALERSHIP, AND WERE AWAITING FOR FURTHER INSPECTIONS. *AK
