Walk Home Condition -I purchased a 2018 CPO Mercedes-Benz S560 on 8/20/21 from Knauz Continental Autos in Lake Bluff, IL. On 9/25/2, at approx noon, I was driving the vehicle and the engine light came on, the throttle/engine felt sluggish and not responsive. The engine felt very out of balance shaking the entire care when the gas pedal was pressed. 5 mins later in heavy traffic, I stopped at a light, the engine started violently shaking and stalled. I shut the car off and tried to start it over a 5 min period. I was able to limp the vehicle to a local Mercedes dealership (Bloomfield, MI). Could only operate the vehicle below 25 MPH without violently shaking. The dealership was only 1 mile away. That dealership was able to quickly check codes. When I arrived the engine light went out and no codes where set. The assistant Service Manager told me that it looked like cylinder 4 was misfiring, but no code set. He told me that if it happens again, shut the car off and it should reset. I left the dealership around 1pm and continued driving. The issue had stopped. Approx 5 hours later, after driving for 3 hours, the same issue happened again about 5 miles from my home. The vehicle stalled multiple times and I finally got it running and limped the vehicle home at 20-25 MPH. The engine fault light stayed on this time. I let the vehicle sit in my garage on 9/26/21 as I was afraid to drive it anywhere. On 9/27/21 I drove the vehicle to the dealership close to my house. (Rochester Hills, MI) When I submitted the vehicle I was told that because I didn't have an appointment, they weren't sure if they could look at it that day. Service Rep called and said that the vehicle set a code (P030485). They said it would probably go away so I picked it up. Same issue occurred on 9/29/21 after driving for 25 mins. Had to limp the vehicle home again at 20 MPH. I turned the vehicle back into the same dealer on 9/30/21. I have zero visibility on a fix and next steps.

THE FRONT ROTORS SEEM TO RETAIN BRAKE DUST JUST ON THE INSIDES OF THE ROTORS.

KEEP IN MIND THAT THE INTERIOR IS PROTECTED BY THE BRAKE SHIELD WHICH MUST BE CAUSING HEAT NOT TO BE DISSIPATED THEREBY FOSTERING BRAKE DUST TO AMASS. SUCH VIBRATIONS WILL ALARM DRIVERS TO PANIC AND CAUSE ACCIDENTS.

ON THE MORNING OF MARCH 8TH, MY VEHICLE WAS SITTING IN MY DRIVEWAY AND I STARTED IT. I RECEIVED A LOW TIRE PRESSURE WARNING FROM THE FRONT LEFT TIRE. I ADDED AIR FOR SEVERAL DAYS AND THEN ON MARCH 13TH TOOK THE VEHICLE TO A LOCAL AMERICAS TIRES FOR REPAIR. THE SHOP TOLD ME THE TIRE WAS FINE, THE RIM HAD DEVELOPED A HAIRLINE CRACK. I TOOK THE VEHICLE TO MERCEDES BENZ AND WITHOUT EVEN LOOKING AT THE RIM, THEY SAID THIS WAS NOT A DEFECT, BUT THAT I MUST HAVE DAMAGED THE RIM AND ALTHOUGH THE VEHICLE IS UNDER WARRANTY, THEY WOULD NOT REPAIR IT. I CAN FIND MANY CASES OF THIS ON LINE, AND THE SHOP TOLD ME "THIS IS COMMON WITH MERCEDES".
