Upon startup, the back up camera will not display when putting the car in reverse. I could not see if any pedestrians were behind me when backing out of a parking spot. This problem has happened 2 times in the last 2 weeks. So far, the camera resumes working after the car has been turned off and restarted. I called the Mercedes dealership service center and they suggested I make a service appointment to repair the camera system. The car is 3 months old. I will make an appointment to have the car serviced soon.

I have observed on multiple occasions when the vehicle is brought to a complete stop during driving in traffic, the engine will stall / shut off. When this occurs the engine has to be re-started with the ignition switch to be able to drive the car again. Car does not show any check engine error and Mercedes Benz service claims that they cannot replicate the issue. During the course of driving the car for the past 12000 miles I have observed this issue between 6-8 times. In at least 3 occasions this occurred while driving on the freeway and the traffic came to a sudden halt. Separately the back-up / 360 surround camera system fails occasionally rendering the backup cameras inoperable. Service claims to have performed software updates and parts replacement yet the issue still occurs periodically with no remedy from Mercedes Benz.

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 gear selector on the steering wheel of the Mercedes Benz has a park button on it when you change the car from gear to park you press that button. That part button has stopped working. It is a safety risk as the car cannot be parked at the end of the driving and it stays in the drive mode. I have to open the door to activate the parking which is built in to the car

THE FRONT ROTORS SEEM TO RETAIN BRAKE DUST JUST ON THE INSIDES OF THE ROTORS. THE OUTSIDES ARE VERY CLEAN AND SHINY BUT ON THE OTHER SIDE OF THE ROTOR (INTERIOR) BECOMES VERY COARSE CAUSING VIBRATIONS IN STEERING. 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.
