It is 100 percent reliable.
My BMW 2018 x3 is a great SUV. It is reliable and drives very smooth. It has great performance, even though it is only a v4 because it has a twin-turbo engine. The panoramic sunroof really is a nice feature as well. Also, the camera and sensor system is great for safety. The only downside of owning such a luxury car is that the packages are expensive, so to have a "fully loaded" car cost you a hefty penny. But overall I would recommend this vehicle.
