My local NAPA had [Denso remanufactured alternators in stock](https://www.napaonline.com/en/p/DEN2100511), vs the standard parts store brands everyone else carries. They're about $200+core, so a bit more expensive, but cheaper than Honda
Got a Denso Reman, and my mechanic installed it and kept the car for a week to test. So far so good.
He commented that before the alternator replacement, volts would go low when the engine was warm. Now they're pretty stable.
As far as replacements I've had good luck with Rock Auto Sticking to the better brands like Motorcraft, AC Delco, Remy, and Bosch.
These cars have a lot of electronics. A cheap alternator might not be able to handle the load as well. I sell parts for a living and definitely recommend going with a denso instead.
I used a Denso re-manufactured unit through Napa on a 2014 Camry a few years ago. Many short trips as it gotten 4 teenagers through high school. Still going strong.
I went with a reman denso and it's been a while but I swear I remember reading the remans were better than new.
Only only only get oem alternator. They won’t last otherwise. I believe the brand is denso. Other brand only lasted 3 months in mine.
Get the denso reman. Most reasonable option vs buying a new denso at the dealer. Main difference is no Honda logo otherwise absolutely identical.
Defective alternator. Get it exchanged under warranty. Unfortunately, lots of remanufactured alternators from parts stores don't perform up to spec. It would best to get a new or remanufactured from Hyundai or a reliable brand such as Denso.
I've gone through three Denso alternators in the last 4 years! This last one went almost two years before going out.
