Thank you, your experiences have helped me and many others.Your dealer sounds a lot more on top of things than mine. Good to know. My car had the parts replaced but apparently not the software reset after replacement so hopefully they did it right this time. If the message does return though I'm doing a lemon law claim.
As far as fuel economy being impacted I can attest to that. My 2017 Niro LX HEV has a lifetime average of 47.5 mpg over 31k miles. In the same driving conditions this 2020 Niro LXS HEV has an average of 42.7mpg over 2.7k+ miles.
When the part was first changed I had just fueled up the car and I did get my highest mpg before I got the message again at 45.7mpg.
I sincerely hope my car is fixed.
