Ford Fiesta shudder error

I have been having problems with my Ford Fiesta Ecoboost where the whole car shudders at slow speed or when I stop and pull away.

Have taken my car in to Ford Lazarus Centurion a few times while booked in for other reasons and then reported the shudder and have taken a video and showed some of the Ford team members there at Lazarus what I mean when I say it shudders and then after that still booked it in 3 more times for the same thing.

They came back to me and said it was a engine mounting bracket that broke and they replaced it but still the problem happens when I drive and apply the brakes. It is getting worse now and I dont feel safe driving the car even while its under warranty and been looked at 3 times for the reported error and a few times before.
