Default Ford Fiesta - Engine is off but some other motor is on

Yesterday I had one of the most strange experience with my Fiesta, after reaching home I removed the keys from my car, however there was some motor which was still spinning, it could not be the AC as the fan and AC were switched off.

I had a car parked in the front and hence I was not able to open and check which motor was it.

I restarted my engine and the noise stopped and I did not have the problem again.

Has anyone experienced this problem before... or any idea as to what motor could this be.

This could be a radiator fan . I think in some cars the fan runs automatically even if keys are removed and stops after cooling.

Well even I hope it is the radiator fan, but this ran for more than a minute and that's what scared me. Hope I do not encounter this problem again else I may have to take it to the service center

It is the radiator fan.

The same thing happened in our Peugeot 307.No cause for worry.

Read in this forum that this happens for the Fiesta as well.

Radiator fan, common occurrence with most new-gen cars. In fact in my car the fan keeps running sometimes for a few seconds (30-odd) after I shut down the engine. You should only be worried if it keeps running for more than a minute.

Thanks a lot guys.... a big relief.

But I find it strange as to why they have this kind of mechanism, especially after removing the keys. I understand it helps to cool of the engine, but they should have built this in the ECM wherein an indicator should let us know the fan radiator is on. For example Fiesta beeps when you switch of the engine and leave your lights on. This is an helpful feature, but a more important feature like radiator fan should have been included. Hope they make this change in the next version

one more thing to add also let the ECM decide how much time the fan should run to cool off the engine, depending on the battery condition otherwise it will kill weak/old batteries.

Default Its a defect

I have a Fiesta and i have experienced this strange thing 6 to 7 times in the last 2 years of my ownership. As u say it is not an ideal behaviour as it doesnt seem to stop the fan even after a minute which is strange.
To bypass this, i switchon the engine again and then stop to overcome the issue.
Its a defect if u ask me.

Regards
Pramod

Happened with me to once or twice in the past 2.5 years of ownership. Bug for sure. Or some logic that is not understandable by end users. Switching on the engine again, fixed the otherwise unnecessarily rotating radiator cooling fan.

It could be how its been programmed in the ECU. Did you guys have to push your car because the battery was drained due to this fan in 2 years of ownership? Answer is No correct?

It may sound odd that the fan restarts after a while but i think its normal. Other fiesta owners please confirm.

Radiator fan is not normally part of the ignition controlled circuits. Many cars even have warning stickers inside the bonnet to the effect that the fan may come an at any time.
