Hi all,

I have owned my fiesta 2019 ST Line from new and has only covered 22,000 miles but recently a power-train malfunction light has come on at least once a week and is currently in Ford to be looked out for the 4th time in a month with each time them telling me there's no codes and they cannot replicate the fault.

I don't know how to replicate it either it seems completely random initially happening on the motorway and going into limp mode (thank god no one was behind me), second time on a country lane, 3rd time just driving normally in town sub 30 mph and the final time happened when I went to go through a parking barrier from stand still.

It has been recently serviced as per the manufacturer recommendations. All I have to do is turn the car off and turn it back on again and the light goes away and the car begins to drive normally again.

I have read a few threads that state to get an OBD II reader which I will get, but wondered if anyone on here might have other recommendations or solutions?

I have the option to return the vehicle September next year but would ideally like to keep the car as other than the issue above it has been fun to drive.

Thanks,

 

Ask the dealer to elevate it with Ford as it is still under warranty and  that this is a safety issue.  ISTR that if a car fails on the same thing three times you may be able to reject it but without codes(which I find strange, as I was pretty certain that limp mode events  are logged,) it will be hard to prove. My approach would be to get a reader and Forscan and have a good look at it myself for possible codes  before taking it back .

Hello Zak and welcome to the Ford Owners Club 😀

 

On rare occasions that I've never been able to work out, the DTC code is sometimes not logged and is erased when the ignition is turned off. I had a transit connect that used to often go in to limp mode but nothing ever stored in memory. In the end I got the code by having an OBDII code reader with me all the time in the van. When the fault ocurered I was able to pull over and connect the code reader with the engine still running. In my case it was injector number 3 was faulty but each time the ignition was switched off the DTC would clear.

If possible use a laptop with FORScan software and be ready to connect up to the OBDII port when you next get the fault.
