Electronic control unit issue

[Jules0]

Hi, I bought my grandland new in May 2018. Two months ago, I attempted to start the car and although the engine turned over, it wouldn’t start. Got a message saying I had an engine fault and to seek repair. My dealership reprogrammed the ECU and gave it back to me. 3 weeks later, the same problem happened again. Dealership had it 4.5 weeks, swapped out 2 units and gave it back. Less than 3 days later, the same problem occurred and its now off the road again. Has anyone else experienced the same issue and if so, how many times are/were you prepared to put up with the problem before enough is enough?
