I'm jumping in with a negative opinion. I came off a lease of the gas NX 200, and was excited for the better mileage of the the 2019 NX 300H. I picked up the car in August, and mileage was great: 30mpg with 90% local driving, as opposed to the 19mpg I was getting on the gas NX200. As soon as the cold weather came, mileage plummeted. With this last fill up, I'm getting 23mpg. I don't know what the problem is. My guess is that the cold weather is affecting the battery power, so I'm mostly using gas. My daily commute is short, all local roads, stop and go, 10 miles back and forth, so it feels like by the time the car is fully warmed up for EV mode, I'm in the garage. I've tried adjusting my driving style to maximize EV usage, and that hasn't helped. Also, the engine transition to gas from EV mode is extremely rough. The car shakes, it's quite disconcerting. I did bring this to my dealer's attention, and he said this transition is rougher on the NX than other Lexus models. I'm due for my 6 month service next month, and I'm going to ask the dealership to do a thorough check on this car. I'm interested in hearing if anyone else has experienced this, or has any insight?
