Check engine light came on September 2025 and the initial diagnosis was for mixture formation (cylinder 3) is irregular. Issue with the GLE 350 years 2020 to 2022 (from what I saw online) is the engine has an issue with a faulty cylinder head. This issue while driving causes the car to shake. This faulty cylinder has been confirmed by the Mercedes Benz service shop.
