    Trucks a 2017 @ 52k miles, started making like a whining/resonating noise once up to operating temp. Deceided to take it into the dealer to see what it was incase it was something internal. They are claiming alternator and replacement to the tune of $1038.27...gotta love Toyota.

    So has anyone else heard of a failure this early in life? How bad is an alternator install on these 5.7's?

    Alternators should typically last much longer. My 97 Tacoma still has the original alternator ... I assume alternator falls under 36K warranty and not the 60K. Is that right?
    Is the charging system functioning properly otherwise?

    No way an alternator costs that much! A few hundred at auto parts store.

    Lots of horror stories on replacing the alternator on the 5.7L. its under the motor behind the wheels. Not easily accessible.
    The alternator for my wifes yaris was $265 bucks I'm guessing the truck would be around the same cost for parts.
    Looks like shop is assuming its a 5 to 6 hours job at $115 bucks an hour.

    My water pump went at 90k, so the alternator going doesn't surprise me. Its a wear item unfortunately.

    I'm sure you can youtube the replacement,

    Would this not be covered under the power train warranty?

    You can buy a cheap stetescope off Amazon and listen to the alternator and other moving bearings yourself.

    I'm just guessing but i'd say the powertrain warranty would not cover the alternator. but i hope i'm wrong. (This would be seen as a wear item like brakes or a fan belt in my eyes)

    quick search and a new OEM alternator is between 250 and 300 bucks.

    DIY isn't an issue, I do all my repairs and maintenance on my vehicles. I had just taken it in just in case it was something like the timing chain and would have been covered under powertrain. The alternator isn't covered unfortunately. What's weird is they said the unplugged the alternator and the noise went away so it's not a bearing in the alternator, the truck has not shown any signs of charging fluctuations at all. @Roman has the part for $280 and it does look like a pain to install. 52k just seems like a very short lifespan for the alternator, cam tower leak at 21k...just waiting for this Toyota reliability to kick in....

    Unplugged the alt and disconnected the charging lug and no change like the Tech stated, have to wait until Monday for when he is back to get a full explanation of what they did. Other then that LKQ has an alternator off a 2017 with 7k miles for $70.11 and free shipping. Probably the way to go rather then a couple hundred especially when they don't last more then 50k.

    How loud is the whining?...Can you hear it inside the truck?...With the radio turned up? If it's still charging, I would drive it until the instruments said it wasn't keeping the battery charged. But, then, I never go to remote isolated places with no cell service. :D

    Its not really a whining, more of like a resonance/groaning sound. Its pretty annoying, I agree could hold off but would hate to be somewhere when it decides to fully crap out. If this is even the problem, I'm going off what Toyotas tech thinks it is.
