2018 MERCEDES-MAYBACH S 560 Engine Problems

Excessive engine oil lead from the back seal. Also, slow coolant leak. The car has a low mileage of 46k.

My 2018 S560 Mercedes occasionally misfires upon acceleration. This has happened at six times over the past three years. When this happens, the engine loses power, starts to shake, and the check engine light comes on. This happened when I was trying to pass a car on US 301 a week ago nearly causing a head on collision as I tried to get back into the right lane. The problem occurs without any warning. This first happened at 64,242 miles, then at 104833, next 108599, then 119,012, then 121,726, and finally at 126580 (my current mileage). Each time I have gone to a Mercedes mechanic. They have replaced the coils three times and the spark plugs twice. They now tell me the problem is due to the walls of the cylinders delaminating and scratched/scoring and the engine needs replaced (come on, 126,000 miles). They have checked the compression and say...

The engine failed while my friend was driving. The car is available for inspection. My friend almost got into a car accident because the car started shaking and the steering wheel closed up before the engine completely failed. Additionally, the airbags did not go off. It could've been a fatal accident because he was driving on the highway. The problem was confirmed by an independent service center. The vehicle has been inspected by a certified mechanic. The car has had problems since I bought it. The tire pressure would always go down. The steering wheel and car would shake at times, and the tires had to be replaced two times within two years.

Ignition coil failed and cylinder 5 misfired. Car has less than 30K miles.
