Q: Car lost power and now won't start.

asked by on

Car lost power and stopped. Now it refuses to start.

There are many parts of your Mercedes that could be causing it to lose power and refuse to start. Unfortunately, without more information, it is difficult to provide an exact diagnosis to your C240’s issue. Provided the engine did not over heat, it is likely that the problem is coming from something common, such as a failed alternator, a bad crankshaft or a bad camshaft sensor. As mentioned earlier, there are many other components that could be the cause of your Mercedes C240 to stop running, so it is best to move forward with an inspection of your starting system by a certified mechanic to determine exactly why your Mercedes is not performing to standard. They will help you get the needed repairs to get your car back on the road.
