Hello all, I’ve got a 2018 SLC 300 with a problem. When driving along at lets say 80k I give it gas to move up to 100k and I get a surging. Almost like a strong putt, putt, putt! Felt it when I bought the car new but wrote it off to not knowing the car. So today I’m in Sport + and giving a bit with the paddle shifters...suddenly starts running like crap and the engine light comes on. I actually thought I’d have to tow it to the dealer, it was running that bad. Stopped, restarted and the engine light is off and running normal. But I can recreate that misfire, surging, so something is up. Only 8,000 km on it so still under warranty. Any ideas? Thanks in advance.
