Electrical system: “Car dash display indicated to check right rear turn lamp. While checking the lamp, the lamp holder assembly was hot.

Engine: “Cel illumination, engine misfire, stalling, rough running, low coolant indicator light ups. No external coolant loss detectable. Coolant in the engine oil and/or in the combustion chamber. This is caused by a broken cylinder head bolt. Engine coolant enters into engine oil. Coolant might be present in the combustion chamber. Affected engine number up to 1569xx 60 060658. Now the dealership is trying to charge me $7k to have this fixed when it's a known issue on these vehicles. I respectfully demand that mercedes benz USA cover the costs and recall these affected bolts asap.”
