I just had to replace original alternator in my 213k mile 2017.
I legit daily drive an 03 camry, the only thing that needed changing in my 2 years of owning it was the alternator.
For any other car it would be replace but it's a Camry, those items especially water pump and alternator generally needs replacing at 220k but as long as you replace them with OEM Toyota parts you'll be good for years to come.
I\u2019m 43 and only have had 3 cars in my life only Corollas and Camry. I get a new one around 250k miles. They are great reliable cars that run well with basic maintenance. Only wear and tear items have I ever replaced with the exception of an alternateer on one of my corollas at around 200k miles. As long as I can keep going to 250k I will keep buying them.
This year, I needed my (original) alternator replaced.
My last OEM Toyota alternator made it to 250K miles. My future non-Toyota ones failed because they were cheap remanufactured ones and later I found a failing harmonic balancer that was putting extra pressure on bearings of the alternator
Did this years ago in my 5th gen, not because of more Amps, but because for some dumb reason the Alternator for the Celica was $250 reman (back in 2014), but Camry's in the Junk yard with Good OEM Alternators were plentiful. That was after I had 3 reman alternators fail in less than 6 months, 2 being DOA!
My alternator in my 2007 V6 RAV4 died just under 2 years ago (Dec 2023), and I got it replaced at a local Toyota dealership. Now, about 20k miles later, I needed a jump start 2 days in a row, and O'Reilly Auto Parts battery tester said the alternator is dead again. Most sources say replacement alternators should last 5-10 years.
My worst breakdown? A 2003 Toyota Tundra I had died on the highway from a bad alternator and I was able to pull over to the shoulder.
7 alternators in a row. Wouldnt charge. Or only charged for like a minute.
