Owner reviews for alternator

I had beefed up my audio system and the stock alternator could no longer keep up with the amperage demand. I decided to upgrade it myself. Eventually that unit gave out.

Mine lasted 270 000 km before needing to be replaced .

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.

Fords can be really picky about which alternator you use! Even if it’s a remanufactured Motorcraft, it’s worth it. Had a friend with an 11 Edge 3.5 that we put a aftermarket alternator in and it complained errors etc… for months till we finally swapped it out and it worked fine with the Ford part!

I have a manual 2007 Toyota yaris with +185k miles on it and the only thing that's ever needed replaced on that car (besides brakes, oil, and tires) is the alternator a few months ago, which I was able to do easily for <$150.

Next and least expensive, would be to buy a new alternator from Volvo and have them install it. It could be that there is a known issue with the alternator that you put on there if it's not from Volvo.

Bought a new bosch alternator and installed it.

I have experience with both shitty Autozone Duralast alternators and I would not purchase them.

I have shadow codes for my water pump because of it, and my voltage is not high enough at idle, and never surpasses 13.5ish volts. It whines loudly, and it doesn't make the same power as my last alternator contrary to the ratings.

Gates are bad. No go.

I took my 22 Traverse to the dealership last Friday. They told me I had a bad battery...my alternator is completely out. Then they call me today telling me my alternator part has been installed just to tell me that my alternator harness also needed to be replaced...I’m at like $3200 between an alternator and then having to go back and do an alternator harness.
