Heads up (as I didn’t see it in search) there’s an extended warranty on the coils due to a known issue. please check your state and dealer as might vary.
It seems the coils (each runs two cylinders) and the spark plug boots have been updated.
In case it happens to someone else..
I found out the hard way after a 50k A service and spark plug change. I’m still concerned about the timing as it happened right after I picked it up…
started cutting out power just cruising on the freeway. Once I got off the idle got rough intermittently. I’m thinking something didn’t get plugged in and seated.
it went away so I headed (back) towards the dealership…
Engine light comes on and now I’m definitely dragging cylinders.
The outcome I told that there’s an extended warranty on coils (150k/20 yr from build?) or something to that effect.
I was told they changed coil (one not all 4), affected plugs, checked oil, bore scoped, flow tested exhaust (cats don’t do well with raw fuel.)
I’ll need to wait for the others to fail or update myself out of pocket.
The coil happens to fail after service? I’m frustrated they didn’t check, test or catch this. Seems like it would be part of the service checks.

sorry in advance as I’m posting via txt
Correct, my wife had this occur during the first year of ownership and it took two visits to figure out the problem. We noticed the car was losing power when you floored it as it would bog down like it was running out of fuel. Post the fix zero issues ………think it was a batch of bad coils.

so I’m one down, 3 to go. No issues with any others since?

No problem post 3 years, and car runs strong no other issues. Wife loves the car and will not trade it, and I hate MB service centers in my area. We have a great indi shop that does all the service.
