Mercedes-Benz car may fail to start due to a damaged airbag. Safety measures damage: Damaged airbag, faulty seat belt sensor; damaged airbag sensor; anti-theft system issues—any of these problems can prevent the car from starting. Model introduction: Mercedes-Benz E-Class, classified as a mid-to-large-sized car, equipped with a 9-speed automatic transmission, body type is a 4-door, 5-seat sedan, with a top speed of 230 km/h. The car's dimensions are 5078mm in length, 1860mm in width, and 1484mm in height, with a wheelbase of 3079mm.

I was rushing to a meeting that day when I turned the key and the car didn't respond at all, with the dashboard completely dark. I was totally stunned at that moment. Later I learned it was most likely due to the battery reaching its lifespan and being completely dead. With Mercedes-Benz cars having so many electronic devices, imagine if you accidentally left the headlights on or forgot to unplug something from the charging port overnight – the battery would drain completely. A lesser-known issue is if the alternator belt becomes loose or breaks, preventing charging, and the car could just stall without warning. The safest approach is to immediately call for professional roadside assistance to jump-start the car or directly replace the battery, rather than trying to fix it yourself. When a car suddenly won't start, eight out of ten times it's the battery's fault.
