Hi all.

I have a 2010 Ford smax 2.0 ecoboost. 41k on the clock.

Its been running fine and gave us no problems what so ever.

About 4 weeks ago I got in it to go to Edinburgh and pushed the button to start it and.... nothing, it wouldn't turn over.

I then got "engine malfunction" come up on the dash followed by "immobilizer active"

So I called the RAC out and he had a good luck over the car, disconnected the battery and left it and then reconnected it. #The battery was reading 12.3 volts. It still wouldn't start after this so he scanned the fault codes and it kept coming up with "lost comms with ecm/pcm" when checking the various systems.

So after that he arranged to have the car recovered to my local Ford dealer and they had a look at it and diagnosed a duff battery , changed the battery and cleared the codes and finally carried out a battery drain test which was fine..

The car has been fine for the past 3 weeks until this Saturday just gone we had exactly the same issue. Non starting "engine malfunction" etc.

The car is currently at the same dealers who supposedly repaired it last time and they are investigating the fault.

Any ideas???

The first time it happened I had had a couple of "low battery" warnings on the dash but this time nothing??

i had to replace my battery a couple of mths ago on mine,the rac guy reckoned my starter motor was pulling to much???
since the battery replacement its been fine.

i would hope your not going to be charged again for the repair?
