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 it is low across all eight cylinders.    The vehicle has been inspected by a Mercedes dealership and by other certified Mercedes mechanics.   They gave me pictures of the cylinders (attached).    Here are their notes:  Cylinder walls in #1 look delaminated, also scratched, no signs of oil consumption on spark plug, carbon is burnt off #1 piston in center. Preformed compression test on cylinder 1 and 2, #1 dry 140, wet 170, #2 dry 110, wet 170. Just these 2 cylinders are showing leakage past rings, luckily no oil consumption. Compression spec's13 to 17 Bar{ 188 psi to 246 psi } Cylinder #1 dry 160psi, wet 190 psi, Cyl #2 dry 150psi wet 185psi, #3 160psi dry, wet 190psi, Cyl #4 160psi dry, wet 190 psi, Cyl #5 155psi dry, wet 190psi, Cyl #6 155 dry, wet 190, Cyl #7 155 psi dry, wet 180psi, Cyl #8 160psi dry, wet 185psi. All wet and dry actual compression are all too low, likely from the cylinder wall conditions. Being compression is low across all cylinders this is causing misfires at random times across all cylinders.","products":[{"type":"Vehicle","productYear":"2018","productMake":"MERCEDES-MAYBACH","productModel":"S 560","manufacturer":"Mercedes-Benz USA, LLC"}]}]}
