Hybrid battery charge

[Pphumph]

Hi
I have a Kia Niro 3 plug in hybrid 2023 model ( new model) purchased in September 2022.
When I picked up the car the charge in the battery said I had 37 miles and this continued for several charges
Just recently when I charge the car up from an external source I only get a battery mileage of 35 miles which very quickly goes down to 34 miles before I have driven 100 yards.
Is anyone else noticing this issue?
1/ Is this normal for this model ie five miles less than the 40 miles stated
2/ is it the cold weather that is limiting the charge
3/ or is there a fault that I should should get the car dealer to investigate.

Regards
Pete

Almost certainly the cold weather which reduces the mileage.

Hi Alan
Thank you for your reply.
I thought the cold weather would have some impact on my battery charge
I will see how it goes when we get into summer
