Our 17 has 205,000km so far. Has been great. Have gone through 4 sets of rear brakes, maybe 2 front but it might only be one, had to recently replace the alternator.
Actively replacing our alternator now, I used this video to confirm that it was the same sound.
My first car was a E46 316i, under 100tkm on odo, had it for 3 years, literally gave no problems.
Sold the E46 and got a E39 530D because I love them. Has been reliable so far, I've had it as daily for almost a year now and the only critical problems it has had are that the alternator gave out after a couple of weeks owning and EGR thermostat was bad.
Dead battery within months, and car completely shutting off, your car SCREAMS alternator issue. Get it checked out.
This was the only non oe product in my car. When mine went it went . There weren\u2019t any bmw ones available for love nor money at the time. I get 13.8 out of mine as well. Can been fine for 12 months.
Mazda's DO NOT like aftermarket alternator. Most don't work out of the box. You need to get a genuine Mazda alternator.
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.
My friend’s BMW X5 had an alternator fail at 50k, she does a lot of city driving so lots of start/stops.
Labor time is like .7 on the RX8 alternator if I remember my time at Mazda right… imma say like 900 or so for labor is a rip
HAVE a 2022 CX30 @ 79,000 miles. Alternator went out today
