Hello, I'm new, have question about 2018 stator reliability

I vaguely remember that Scotty video, saw it quite a while ago, it's goofy.

Alternators are pretty much a routine wear item in conventional cars.

There have been some Prius transmission failures reported here. So it's not as if it never happens. But you're not likely to ever see one.

 

change the tranny oil, you'll be fine

 

Haven't seen any reported on Gen 4 - it's a very different arrangement from the earlier ones, so the early car's track record be irrelevant. Plus - I've read very few with older cars.

That said - there have been (older) PRIUS which drove 1,000,000 kilometres as taxis with only routine servicing, tyres and brakes.

 

no worries

 

I agree with Bisco. No worries..
A lot of the YouTuber Channels like to do that kind of video as click bait. I have seen the video that you are talking about. Very few problems with the Prius set up. If you do change the fluid make sure you use Toyota brand fluid for the Prius to avoid breakdown of the insulators within the transmission. ( the stater or in the video he called it alternator)

 

Yep, no worries! I like Scotty but he can tend to be a bit dramatic and over-generalize sometimes! My favorite Toyota YouTuber is "The Car Care Nut" who's a master Toyota mechanic/technician with over 10-years experience so has worked on probably thousands of Toyota's.

One thing he's seen is Toyota engines starting to burn oil if the owners don't change the oil regularly. He suggested every 6-months or 5,000 miles, whichever comes first, which is what I go by in our three Toyota's. He's seen many cars burning oil that have only had oil changes every 10,000 miles, including Hybrids.

 

There was a time when Scotty was Not a Hybrid fan !! like a lot of mechanics that still are not hybrid fans.
Scotty has come around slowly to the benefits and pretty good reliability of the new technology. He still gets some stuff bass ackwards regarding prius, like most of us do from time to time .. To Scotty's credit he does do retraction videos when he's aware of something in one of his tubes that's wrong. And I think the best way to describe the comparison of the alternator to the the prius motor / generators (MG1 and MG2) which are the heart of the prius electrical system, was mostly just a rant about a new technology that was not clear to him yet exactly how it worked or how reliable it actually is. There are still plenty of things that can and do go wrong with prii and some are very expensive, especially when a dealer shop does the work, but the motor / generators (MG1 and MG2) are not typically one of those things that fail in a prius.
