Got a remanufactures duralast alternator. Worked for about a week and the died.
Cons: died quickly, short lifespan
Reman alternator quality is in the toilet. Not uncommon to have to warranty an alternator once or twice.
Cons: alternator quality is bad
I started having problems like my alternator was going bad again so I replaced it with a duralast alternator part number DL2618-6-11 because I had a lifetime warranty on it and it still didn't fix it so I was thinking it may be a wire shorting out was playing around with the wires that go to the alternator and the plug on the back that goes from the alternator to the PCM and it's started charging again ( I guess it finally connected the electricity) so I replaced the plug on the back of the alternator. It fixed it work for about a month then it happen again check charging system battery light on and battery going dead so I was done. I took it to the Ford place they wanted to replace the other side of the PCM to alternator connector which they did and the alternator so I got another AutoZone lifetime warranty alternator and when they did that they said everything is charging and running like it is supposed to be but your PCM is still throwing the battery light and check charging system because your alternator is charging at 14v and for the PCM to cut the light off it needs to be at 14.6 v. So they wanted to put another alternator on it because they said the alternator from autozone the voltage regulator wouldn't let it go to 14.6 volts. The car runs and drives and doesn't have any problems I just hate the light being on to be honest I have spent hours on the Internet trying to see if it's just these AutoZone alternators that aren't letting it get to the volts the PCM wants or not haven't found anything.
Cons: insufficient voltage output, battery light remains on
Vehicle:
Ford Mustang
Part number: DL2618-6-11
Unfortunately it’s proprietary Hyundai/Kia part. It’s now a common problem that if the alternator goes, so does the transmission because the low voltage fries the shift control solenoid. Lots of people complaining about this and yes, it happened to me.
Cons: proprietary part, common failure, fries transmission
Vehicle:
Kia
