I also texted the dealer who did the battery replacement if the replacement battery was also under warranty to the same 100,000 mile or 10 year deadline, but they never got back to me on that. ..RT
Great news that you got your car back and it is good as new.
I think your battery is the same 27kWh.
The warranty will carry on from when the car was first sold, not start again from when the pack was replaced.
To know for sure what battery you got look at your invoice. Or ...
Download the SoulEVSpy app
and look at the cell map.
If it looks like this (96 cells) it is the same as the original.
If it shows 100 cells you have a newer bigger pack.
Update: 8th April 2019
One of the 3 cars in Quebec that claimed to have a bigger 30kWh battery pack is now known not to.
When tested with Torque using the 30kWh codes we see there is no cell 97. see - Facebook: KiaSoulEVQuebec: March 25 at 8:19 PM
