2015 C400 Sport Engine Shakes

When I start the vehicle and is in park position or when I'm at the stop light the engine shakes and/or kind of shivers. I can feel this when inside the vehicle. Anyone else experience this?
In addition, twice now the engine has stalled at the stop light. Not sure what the problem is. Sounds like I need to take it in to the dealership and have one of the technicians drive with me so the can personally witness the shake.

Thanks,
Ike

Time to visit the dealer. The motor definitely shouldn't struggle to maintain a clean idle.

Check for collapsed motor mount(s).

I'd suspect motor mounts, too.

I've been having the same issues when I first start up the car in the morning. You could feel the shaking/shivering happen. Other than the first start up it doesn't happen again.

It is not suppose to shake. Would get it checked out.

Have you taken it to the dealer yet? If so what did they do to correct the problem? Thanks

I've been fighting this issue as well, but add in the engine stalling. Back in to the dealer for the 10th time this year. Voltage dip limiter was replaced but didn't fix the problem.

Same symptoms everytime:
- Eco start/stop disabled
- Car driven a short distance after a cold start; engine still not up to temperature
- Stopped at the lights with foot on the brake
- Can feel rough idle but RPM gauge sits at 700
- Slight judder and RPM blip then engine stalls and all warning lights lit on dash; transmission shifts itself to neutral
- Restart the car - car starts normally with no warnings or CEL; have to shift back into D
- No stored codes
