Horizon 4 is quite a buggy game isnt it?

I keep noticing a number of bugs/problems in Horizon 4 and they really put a downer on the game. The 4 that I come across most are:

1. In a high powered car with a high revving engine, sometimes the sound will freeze when the engine is at max RPM so the engine sound just keep playing even if I pause the game. And then when I unpause the game, the sound from the engine disappears completely (it's like driving round in an electric Aventador and nobody wants that). This happens multiple times when I'm playing and it's super annoying.

2. When I'm at the festival or a house and I go into My Cars, the car select menu and take a good 30 seconds to appear sometimes (yes I timed it). This too happens every time I play.

3. In the car select menu, I'll be scrolling across the manufacturers and the preview image of the car won't match up with the actual car is. E.G. a picture of a Honda Civic will appear in place of a Porsche 918 Spyder. Sometimes, the preview images don't appear at all. This happens multiple times when I play.

4. The rewind function doesn't always work. I will press Y to rewind once, that works. I'll then press Y a second time but the game doesn't rewind. It makes the rewind sound but nothing happens. Press Y again, oh good the game decided to rewind this time. A small bug but a very irritating one.

These are just the bugs/problems I can think of right now and whilst the are small things, they happen all the time for me and really put a downer on my playing experience.

Has anyone encountered these bugs? I'd be interested to know.

I'm playing on an original Xbox One.

EDIT: Thanks to all for their responses. I've been encountering these problems before Fortune Island was installed.
