Well, I'll be surprised if they did test the car in cold winter.
Few examples here:
1, My rear view camera doesn't like cold temp and doesn't want to work in below -10C.
2, Auto-folding wing mirrors often freeze in closed position when I unlock the car. Had to push them out manually.
3, It takes AGES to heat up the car. Both the engine and the cabin. It takes approx. 20km motorway drive to get the engine warmed up and at least 15 minutes to get the cabin somewhat warm (I set the temp at 30C on full blow). Well, it's like sitting in a freezer every morning.
Also, NO AWD models available for a country that really need it. WTF?!?! All othe makers Lexus compete with offer AWD.
