Crossland X2018 whining when reversed onto an inclined drive

[Gazza]

Hello, I bought a used Crossland X, 2018 (68) a fortnight or so ago. I have two parking spaces at the front of the house, both have an incline. Due to having three vehicles temporarily I was parking the Crossland across the two spaces and not on the incline. Now that I have got rid of the third vehicle, I am now reversing the Crossland onto my driveway/parking space. I am finding that when reversing up the slight incline, the car makes a whining/droning sound. I tried going back and forth, sometimes it goes away. I have reversed up the street which is a lesser incline and it doesn't make the noise, just normal reverse gear type noises, I've reversed round corners and on a flat for a distance and just normal noises, no whining.

What is this noise and should I be straight back onto the seller before 28 days are up?

I'll try to upload a video if I can.

Any advice would be appreciated.

Thanks.

Here’s the video, I kept the the registration out the video but you can hear the noise.

Apologies for the moss all over the drive, neighbour got a guy to clean her gutters and he’s got moss all over the place

The above video, it whined the first two times I reversed up and went back and forth, the third time it quietened down. I went out to the car again 10 mins later, pulled forward then back up the drive and it did it again but not as loud.

Not sure, but if in doubt then raise it with the seller to see if they will get an inspection on the transmission (oil change, etc) otherwise if it doesn't whine in normal service then not sure I would worry about it
