2016 prius four - 186k miles

Have you driven it - shouldn't have much undue road noise, and yes, they're very comfortable.

The battery will "likely" last the life of the car - the brakes and transmission too - normally.

BUT - the caveat with ANY CAR at 186,000 miles is that - nothing lasts forever. Check how it's been properly serviced and looked after. Have it well checked over before purchasing. High miles might give you a lever for negotiating a lower price - check locally for what the going price is.

 

1) no

2) 150-200,000 miles or 10-15byears, whichever comes first on average for gen2 and 3

3) yes, more than i would prefer

4) compared to a bicycle, it's a rolls royce. compared to a rolls, it's a bike

 

186,000 miles for 9 grand? There are other Prius out there that have less mileage for just a little bit more money although a 2016 with 186,000 miles is probably mostly highway miles....easier on the engine and car for sure.
But if you are planning on buying....

I have a 2018 Prius 4 and have driven a 2016 that is owned by my brother. I have noticed a few things.
The 2018 is somewhat quieter than the 2016. It seems that there is a bit more sound insulation....and my 2018 has sound insulated double glass where his seems to not have it......although it could also be the tires. I also have noted a difference in handling and ride. The 2018 handles a bit better and the ride quality is more Camry like than the 2016. Now it could very well be that the differences is because of the tires. I changed out my factory Toyo tires to Bridgestone Touranza tires the first week of ownership. Made a huge difference in ride quality and road noise. I also added insulation (Boom Mat) to the doors, rear trunk and floor. That also helped. Talked to my brother and he changed his tires out to the Bridgestone's and noticed what I have...better ride....quieter.....I have installed the Comma AI driving system and that made the car way much better....it should be a factory option!

Don't worry about the battery. Lots of info on this site and other places about Prius going several hundred thousands of miles on the original batteries. The secret it seems is to keep the battery fan filter clean and to use the Prius....don't let it sit in a garage not being used. Those batteries seem to need to be used to stay healthy.
Hope this helps.

 

I'm brand new on THIS forum but have done some research. My results were that there are very, very many people with over 200k on original battery. It also seems that age affects battery more than mileage. But I'm no expert.

There is a member on another forum with a 2016 who just passed 600k miles. His maintenance and repair list is laughably small. These cars seem to just keep going.

 

Road noise and comfort are entirely subjective. You just have to drive it for yourself. Wheel size (15" or 17"), as well as the specific tire have a lot to do with the noise and comfort. There are two types of batteries in the 2016: NiMH and Li-Ion. The Li-Ion was first used in 2016, so not so many high-milage cars as the earlier generations with NiMH to have a solid opinion. Experience with high-mileage NiMH batteries is extensive and this shows that the cells lose their ability to keep a charge over time. This is evidenced in the car by the battery level depleting rapidly as well as filling rapidly--the battery gauge swings from "full" to "empty" very rapidly. At this point, general MPG will suffer because the battery is not providing a steady stream of energy and you use more gas power to move the car as well as continually charging the battery. At this point, you can have your NiMH battery re-conditioned by third party shops, extending the useful life of the battery pack. Toyota will only replace the entire battery. I have recently read that some folks are developing a Li-Ion replacement pack for NiMH cars, indicating to me that Li-Ion is the more desirable technology to have.
