My alternator just died at 83k miles but otherwise it’s been painless I love the car
I have a 2007 CRV with 132,500 The car has been reliable and I'm currently dealing with replacing parts due to the age. Since the last quarter of 2025 I replaced the tensioner/belt,mid pipe, muffler/hardware and alternator.
I had this issue with my 2013 civic. Was replacing the battery about every 12-18 months. All the systems tested fine but the problem was fixed when I finally replaced the alternator.
I had a 2016 accord sport that i just sold with over 200k miles. It has all its original belts,water pump, valves,thermostats, and sensors. The only major thing i changed was the alternator. I did regular maintenance and fluid changes with no issues and of course batteries, brakes, and rotors.
the oem has been good for 5 years now
I have a 2001 Honda ST1100 and the bike is a beast. My alternator went out and I had to find a compatible model on ebay because they don't offer the OEM anymore.
Only use Honda oem denso alternator. Yes they are expensive but you will be replacing it again if you use an off brand. Been there, done that.
He replaced the alternator and serpentine belt. Parts $208 for alternator and belt. Labor $100. Limited lifetime warranty on alternator and 3 years on belt. Honda Civic.
good luck ever finding an oem alternator that isn\u2019t $1700 from honda dealership. Denso been on back order for fucking years somehow
They're pretty expensive. Our Honda Odyssey needed one and it was $700 remanufactured. The labor is pretty easy but the part is pricey
