Hello. So I've owned my 1L Fiesta ST-Line X for about 11 months now, and in those 11 months, it’s just been issues after issues since it was bought. It’s had a whole new gearbox, new headlights, three sets of 4 tyre sensors, and a new clutch. Most issues started when I bought the car at 57k miles. Which fair play, the dealer paid for the clutch and the gearbox, which in all fairness, as they should after selling me a faulty car (Inever test-drove it), did take them nine weeks, but in the end, it got sorted. Nine months later, the car started making this sort of squeaking noise. its always on and off sometimes it happens and it would make this noise heavy for a few days than just randomly stop for a few days like nothing happened when the car is at complete stop or when ideal. but as soon as rev it the tiniest bit or start moving the sound stops. My bet is the aux belt. (Video on that noise is under the video IMG 1744 https://youtube.com/shorts/Cik0E9_AMAw) And now recently, the engine has been vibrating like mad. It goes straight through to the inside of the car, but as soon as you put the clutch all the way down, it stops. My guess is that it could be faulty engine mounts, but it wouldn't explain why it stops with the clutch down. https://youtube.com/shorts/jRVIDYdtjQo

does anyone know what these noises are
