Reliability Mazda 3

Hello everybody, we have a change to Mazda in January. It will be our first Mazda. It will be changed from an Audi Q3 2.0 170hp to the new Mazda 3 with either 122hp or 150hp. Have we looked at the car yesterday and will make the days a test drive. The materials and even the entire interior for the price, simply the hammer. But what is the reliability at Mazda? Have now read on the Internet several times that the new models are often strikingly already with the r first HU have problems with suspension components? Is that true? The Audi once had a defect in the water pump in 8 years, costing about 400€, that’s it. Can you expect the same reliability at Mazda? Thank you in advance!
