Mercedes GT Roadster Starting Issue

I'm having a starting issue with my 2021 Mercedes GT Roadster with a gasoline engine. After driving it for some kilometers, the engine increasingly fails to start. Sometimes while driving, the engine shuts off, with rough running beforehand. The dashboard lights are behaving erratically. Could a defective fuse be the cause?

I experienced similar issues with my GT Roadster. Have you checked the ignition coil? It had the same symptoms: starting issue, engine start failure, and rough running. Were there any dashboard lights on?

Thanks for the response. Regarding the ignition coil, how did you assess its condition? Were there any specific diagnostic codes, or visual signs of damage? Was the solution more than just the ignition coil, or was that it?

The fault was the ignition coil. Given the unpredictable nature of these issues, I recommend a thorough inspection at a workshop to ensure no further damage has occurred.

Thanks for the guidance. A technician found a defective fuse related to the ignition system. The replacement cost 52€. The car now operates perfectly. I appreciate the help in resolving this.
