Alternator Denso or OEM Mazda

I went with a reman Denso alternator over a new off brand alternator for my Camry and had no issues.

Update: I ended up sourcing my own parts and sent them a quote from someone else and they matched it. Will have a Denso alternator installed and Costco battery for about $1k.

Manual, buy a reman denso or used or new OEM off the eBay or other seller, harder to rebuild those in my experience.

Have never had to warranty out a denso alternator.

Denso and alternators from Toyota are the only ones we\u2019ll use for this exact reason.

Similar symptoms when my '05 factory alternator died. Get a jump then measure the voltage at the battery. If it's ~14VDC, the alternator is charging. If it is only ~12VDC replace the alternator.

Denso or nothing. You'll be doing this again in about 2 years if you chose poorly.

Get a denso reman or be prepared to replace it again in a year.

The Denso branded remanufactured alternator arrived from Rock Auto with a broken plastic socket. I arranged a return and replacement, but the second unit also arrived with the exact same damage. I believe the issue is with Denso's factory packaging, as the alternator is placed socket-down without cushioning. I returned the second replacement for a refund.

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.
