My alternator died in 32k kilometers.. (Audi Japan took care of it so not that bad). Otherwise the 3 lit twin turbo engine is amazing.

I love driving it on the highways, however small roads in Tokyo and small parkings are a bit challenging sometimes but the 4 wheel steering comes handy.

Pros: amazing twin turbo engine

Cons: alternator died

Vehicle: Audi Q8

Mileage: 32000 km

Mazda's DO NOT like aftermarket alternator. Most don't work out of the box. You need to get a genuine Mazda alternator.

Pros: genuine Mazda alternator needed

Cons: aftermarket alternator bad

Wouldn\u2019t recommend unless you like spending your time on the side of the road or at the dealer. Mine just went back to my local dealer today for its 4th alternator in 32k total miles, 3rd one in the last 6 months. Literally just got the car back 5 days ago for the same issue.

Pros: Fun to drive

Cons: unreliable, frequent alternator issues

Vehicle: Audi

Mileage: 51500 km

My 2017 Mazda 3 touring felt like it was cursed. I had the direct high pressure fuel pump injector go out like 1.5 years after purchase. About 2k for just that repair. Thought that was the end of it until the following year where there was a persistent evap problem that nobody could find, despite clearing the code it wouldn’t pass smog. One smoke test and several hundred dollars in appointments later they found the smallest leak from one of the hoses, replaced it and passed smog. Then the check engine light saga started, at first we thought it was the battery/alrernator until after replacing both it kept happening. Turns out that was the start of my catalytic going out(76k miles exactly). Idk if it’s Stockholm syndrome but i did trade it in for a new Mazda. Hoping the curse has been lifted.

Pros: passed smog after repair

Cons: fuel pump injector failure, evap problem, check engine light, catalytic converter failure

Mileage: 76000 km
