Thanks. Was looking more at the motor/gear reduction issue. Drove both the Niro and the Kona and they seem like good cars, although this issue along with the battery problem for the Kona is a little concerning. Really hard to tell if the new motor and/or other updates has solved the first problem? The VW ID4 also seems like a possibility, although the reviews on the infotainment system are a somewhat mized.
A couple specific thoughts on this:
1. People reported the motor issue with both the Kona and Niro. So if you're aiming to ensure that you don't get a car with that issue, I'm not sure Kona is the car you want to buy.
2. Kona & Bolt had battery issues on their older model years. As far as I know, the 2021/2022 model year of both cars does not have this issue.
Like you, I read this forum and saw people complaining about the tapping noise, before I signed the papers to buy the Niro EV. I told the dealer I had some concerns about this, and he assured me that since the drive train is covered by a 10 year warranty, it shouldn't be a problem for me, and they'd take care of it if it became a problem.
I own one of the Model Year 2019 cars (I don't think there's a MY 2018 by the way). And to date, I've had no issue with that rattling noise.
If this is a concern, though, just be sure that you live near an EV-certified Kia dealership. Don't do what some did early on, and buy it out of state and then drive it 100's of miles home. Because if you do end up with an issue, getting it addressed will be an enormous pain.
I can't opine on the ID4 from personal experience, only what I've seen in reviews.
Niro EV advantages over ID4:
- Excellent efficiency. 123 MPGE city, 102 MPGE highway. This is about 15%-20% better the ID4, which means your electricity charges will be meaningfully lower. (ID4 is 104/89)
- Tactile buttons for everything. (This is an advantage to me, but I'm sure some people disagree)
- Car gives good info on EV stuff. Range estimator is reasonably accurate, plus can show current charge rate and % charge easily.
- Has a large covered area in the trunk - meaning you can stash things there while making the trunk look empty
- Charge port in the front - since I live in a no-snow climate, the front doesn't get especially dirty, and it's very convenient for plugging in at most locations. This could be a con if you live in a wintry climate with a lot of salted roads.
Cons of Niro EV:
- In low (< 50 F) temperatures, the DC fast charging speed is not optimal. If the car is sitting out in frozen temperatures overnight, the car will not charge faster than 24 kW
- Slow-ish DC fast charging max speed (in optimal temperatures). The efficiency helps compensate for this, but the ID4 still charges more miles/minute than the Niro
- Back seats' leg room is less than the ID4 (although far better than the Kona's)
