I have a BMW 330e series, so many design faults which is later found to be "common" in BMW cars when searching online. 2 days of rain in London caused water to be trapped inside the door, hearing gushing noise every time I drive the car and brake it. Searched online and turns out hundreds of people have come upon the same situation which is such a bad design fault. only solution was to drill a whole from the bottom of the door for the water to come out, but luckily I was once parked uphill and the door kept leaking all the water trapped. Yesterday was the second time just 2 months apart where I was driving normally until I heard a loud squeaking noise as if I was dragging a piece of metal on the ground. First time they towed my car to inspect it and turns out AGAIN it is common in these BMW's which was also said by the BMW services when I called for help. They knew straight away what I was explaining because of the regular calls they get. Apparently a small stone on the ground got between the brakes and the disc causing damage to the whole disc which needed replacement and we had to pay as insurance did not cover it. Yesterday the same thing happened as I was driving back home from Harley Street and I heard the same noise again. I could not believe it was happening again as we changed and fixed the whole problem just under 2 months ago. Had to drive home with this loud noise which made me feel so unsafe, as if the car was gonna pop it's tires any time. People on the street closed their ears from how loud the noise was, honestly was embarrassing for a customer having a BMW with all these faults. BMW services were called again and the same thing happened where the guy picked up and laughed midway as I was explaining and stated that I don't have to worry as this happens regularly for BMW owners. Might have to switch to Audi or Mercedes at this point.
