New member here. I bought a GT Blackline 1.8 T just over a month ago. I am very pleased with the car. Although I just went to drive the car, put it in reverse and the parking sensor was permanently beeping. I checked the sensors & one of them had popped out. I tried to push it back in again (it has a sort of spring device at the back) but it wouldn't hold. The car has just been sitting on my drive. No one has touched it. Is this something that has happened to anyone else. I'm taking the car to my local Alfa dealer (Brighouse) for them to take a look at it. I will let you know how I get on - I am expecting it to be a hard job to explain that this has happened of it's own accord and therefore something I don't expect to have to pay for - seeing as the car is just over a month old. The advice of other forum members would be very much appreciated.
