What kind of childhood diseases has the new Berlingo 3

Hello you, I want to buy a new car soon. It will be a family car. I like the new Berlingo 3 very much (HDI 110 Ps). Now my question, since I have never had a Frenchman. What diseases does the new Berlingo have? I have already been informed about something from a “Poltergeist”. Some owners were talking about noises in the chassis (lutes clacking and polter). Also the gearbox is not spared. In the electrical system it seems to give me problems. . Please indicate whether you have a petrol or diesel. Greetings
