First time poster, replying to an another first timer. 3 months ago I moved from an is300h to a NX350h.
So far so good, no issues except the petrol flap. Flagged that to the dealer who never queried it and booked me in for a replacement within a couple of days.
The only other issue was dealer related, they forget to fit the pre-agreed dash cam which they fitted when replacing the petrol flap.
MPG is steadily getting better, now up to 45.5.
