Mazda 3 experiences? – Model from 2019

Dear MotorTalk Community, I am very interested in the current Mazda 3 (4th generation). To be more precise, I am planning to finance a Mazda 3 as diesel and as automatic – built in December 2019. Now I have looked at pretty much all the reviews (both in German and English) that exist. Up to now everyone from Mazda 3. However, I have recently come up with the idea to look around for problems with the car (on YouTube). Customers from the USA seem to have an incredible amount of problems. It starts with problems with vibrations and clapping in the doors and stops with non-functioning assistance systems, which threaten to fail even in light snowfall. Since there are only a few videos and I am aware that it is of probably 10,000 customers only 10 who have problems, I thought it was half as wild. However, in the comments there were all the more customers who shared the frustration and allegedly the gleic Among the comments, there were customers from the UK who had no such problems. Are the Mazda 3 built elsewhere for the North American market? And if so, why do these customers have so many problems? I now appeal to all the members who drive a Mazda 3 of the 4th generation here in Germany. Do you also have such problems? Should the Mazda 3 be avoided better? Is the car reliable, or is it only a permanent vehicle? uftrag for the workshop? Would you buy the car again, or should I leave my fingers off it? I am really insecure and need your advice urgently. Thank you very much.
