My 2006 R-500 is leaning from the (front and back) passenger side, causing the vehicle to be unsecure to drive... It feels like both side tires are TOTALLY FLAT. I'm not a mechanic, but it looks like the AIR SUSPENSION IS MALFUNTION

I was purchasing a 2006 Mercedes Benz R500 Black on November 3,2021, VIN: [XXX]. in the process of driving the vehicle less than ten miles, part of the part of transmission case broke off. The steering was hard to turn and this is a Salvage vehicle. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
The vehicle's rear drivers side brake or reverse light would not go off for a week (to my knowledge) and while sitting in the passenger side I turned on the heat warming device and there was no problem. It was after we had been shopping and returned to the vehicle did we notice a smell of something burning, but could not tell where it was coming from. Still unaware that a fire could start from the back of the vehicle, is when we realized that the cargo area of the vehicles side panel was in complete flames! Thus, causing physical and mental injuries, smoke and property damage and a complete sense of insecurity. The vehicles main security feature never warned us of any potential life threatening danger as it would if my tire was low and the on call system failed to be helpful when trying to get help, for we were only able to hear the representatives but not communicate with them which LED to 5 representative disconnect calls.
Vehicle has been undriveable on and off for 6 months with defective starter wiring harness which the wires are exposed, and starting intermittently. Towed from the street 2 months ago and sitting at the mechanic trying to help me. Mercedes benz has a safety recall #2006040002 for the exact problem. They tell me it is for the 2006 r350 and not the r500 maybe because they were very limited. Theses models are the same built chassis everywhere, including the starter wiring harness, except I have the upgraded v8. And they refuse to fix. Since this has caused me break down issues and is a potential safety hazard as described. I have paid $1200 a year ago to replace a defective wire harness inside the chassis, as the car smoked and almost caught fire as I had to pull off the road and tow. Am I stuck again?? [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
As per recall#2006040002 is the exact problem I am having now. The starter wiring harness is defective and exposed, and car is disabled at mercedes mechanic site. Mbusa says it is only to certain r500s and VIN specific. I am confused since this is limited production.
After diagnostics found that the front sam had been under water shorting the sam and almost causing vehicle to catch fire. Would need the front sam and wiring repair along with connector replacement to move forward with diagnostic. The water is coming from the firewall on the passenger side. Was at work had to leave it at my job because it wouldn't start so the next day I had to have it towed.
The transmission has a faulty shift solenoid that can only be replaced by a mercedes benz dealer and therefore is many times more expensive than other repairs. Also this solenoid has a well above average failure rate. My car has 112,000 miles and the transmission began shifting poorly and got stuck in 4th gear. Can became very jerky and once went into park without me selecting park, this happened at a stop light with cars coming up behind me.
Consistent issues with drivers side airbag. Sms light comes on after being repaired sporadically. Multiple repairs documented via bosche and ase mercedes benz repair facility. Spoke with hendrick mercedes benz and they advised that a voluntary recall for the airbag was issued but is no longer honored. I was never informed of the voluntary recall and the factory mercedes benz dealer is no longer honoring the voluntary recall. I will need to garner the previous repair invoices from the certified mercedes benz repair shop.
