Grinding noise while driving, continues after engine is shut off

  • 2011 FORD FIESTA
  • 80,000 MILES
While going around a tight bend on the highway my car started making an awful grinding sound. I pulled over and turned off the car. I restarted the engine, everything sounds fine while the vehicle is not moving. When I let it idle forward the grinding sound resumes. When I put it back in park and turn the engine off the grinding continues briefly before stopping.
Do you
have the same problem?

Hi and thanks for using

Since you mentioned that the noise continued a couple seconds after the engine was off, the first thing I want you to check are the cooling fans. With the engine cold and key out of the ignition, see if you can turn the blades easily and if they make noise.

Here is a general link that discusses the cooling fan:

Next, if the fans are fine, next you will need to remove the serpentine belt and check all belt driven accessories (alternator, power steering pump, water pump). Check to see if any have excessive play in the pulley and spin them to make sure they spin easily and make no noise.

Do this and let me know what you find.

You mentioned the sound was when driving, and then you shut the car, restarted it and everything was fine until you placed it in gear and allowed it to move. After that you mentioned it continued for a couple seconds when the engine was off. That is what I am basing these test on. If it continued when the engine was off, my first suspect is a bad cooling fan motor or the blade is hitting something.

Take care,
Was this
