My partner has always took his car to the same garage for years. My partner was ill so this time I took the car to a different garage nearer to where we live. The car failed its mot on the sub frame and was told this was a dangerous defect and not to drive it. They discovered that the car subframe had been filled with fibre glass. In 2016 we were told that the subframe had a hole in and that they would weld & plate this and we paid for the repair to be carried out. He then passed an mot on this vehicle a further 3 times. What I want to know is this the correct way to repair a subframe and if not what can we do about this?
