My first misfire - 2019 AMG C63s Coupe
I honestly think you just unfortunately got a lemon. But it totally makes sense if you want to leave Merc after your experience.

I do not even know what they changed and what they did not anymore. They changed only one spark plug again? I really think you should not let them get away with this. If one spark plug has carbon deposit, the others most definitely do. They should change all 8 or nothing.
So many people here already previously advised to lemon and get rid of it
Thought you were trying to figure the process out but
if you are okay with getting treated like this, then so be it

I’m going to shut up here and give you technical info only...
will have to drop off the car back to dealer on Monday I guess at this point


Good luck, I suppose the thread is entertaining to read, if nothing else...

I’ll post my Laguna Seca final lap here which I enjoyed sometime today.

While I have no doubt your car is a lemon, I can't help but notice the complete incompetence of your dealership though. I personally think your injectors and spark plugs were completely fine. Something is frying them again and again. So if the ignition coil is going kaput again and again, clearly it is not your ignition coil that is not wonky. It makes way more sense to start with your engine wiring harness. Regardless if you can get the car declared as lemon or not, I would have created a havor in the dealership for getting this fixed. It really is not that hard to fix a problem like. There is only so many system. Change everything in the line altogether and problem should technically be gone. They are just playing with you and changing things one bit at a time.
Btw, I had a 2020 GLC 300 (****ty still) loaner for a while with updated MBUX which I loved the system. I don't like our infotainment system anymore lol
@OP - Any updates regarding your issue? Did you continue to see more CELs after repeated fixes?
P0300, P0301 and C0703

Yeah, I haven't been keeping you guys up to date. Took the car to a different dealer (after the joy ride issue with my previous dealership). They also work with MBUSA using the same open case with them. This time they were told to open the engine and check for any mechanical failures (see below pics). Per my new SA, no mechanical issues were observed and no fixes were applied. MBUS has ordered the dealership to keep driving the car and observing the Misfire issues. My car has been driven all over, even stays the nights in technician house (per Mercedes Me app) I even seen the tech taking the car to shopping center (not sure exactly why)...
My Lemon Law process is still moving forward but very slowly. The car has been at the dealer for total of 178 days as of today with total of 4 trips to dealer. I took delivery on April 4th this year. I only had the car for 85 days which was mostly garaged due to my accident...
Hoping to start a better year next year

Again, I'm only providing technical info here and nothing else.
