When driving the car at 80KPH the RPMs are just over 2,000 and when it’s at 90 it’s like about 2.5k, is this normal for the car?

It sounds like the transmission is not shifting into overdrive, can you count the shifts to confirm there should be 4 shifts. Also, let's run the codes to see if any are stored.

Also check the transmission fluid level.

Can you please shoot a quick video with your phone so I can hear the RPM noise? That way I can tell for sure what's going on. You can upload it here with your response.

Please go over these guides and get back to us.
