W205/W213/X253/R172 piston cracking - questions on car condition? Cross posted
Seeing a surge of engine failures/piston cracking and curious on the following for those that have had the issue in the US
M274 engine specific in the :
2015-2018 w205 C300
2017-2019 w213 E300
2016-2019 x253 GLC300
SLC300 R172
If you've had the piston cracking issue (different from the wrist pin loose tolerance issue with the known SB on the early w205's), can you reply with the following?
1) What vehicle year/model and mileage at the time of the issue
2) What's your oil change frequency? The standard 10k mile interval?
3) Is your car subject to severe usage (short trips less than 10 miles frequently, hilly areas, extreme temps)
4) Have you had an induction service done prior to the failure?
5) Have you run any fuel additives prior to the failure?
6) Have you always used top tier fuel at 91 or greater octane?
7) Is your start/stop working normally at the time of failure?
8) Has your engine air filter been changed @50k miles/ prior to the failure?
9) Have your spark plugs been replaced @ 50k miles/prior to failure?
