 Where to start. First I will say it does get great gas mileage and is excellent in the snow but that is all the good I can say. I bought my Rouge Sport in October of 2017 and since the beginning it has been a problem. I start my car on cold days and about 10 minutes later get in and it's a cold as when I started it. It takes a couple of miles of driving before it starts to warm up. The heat starts to get warm, but not warm like it should and the needle will start to move to warm then a few miles down the road the heat starts to blow cool again and the needle has gone from warm back down to cold. I have had this car in a million times, have pictures of each stage w/o the the mileage and time in the picture and they swear it is normal. I have gone to Nissan cooperate since the dealership just does not get it and gives me a hard time. They had me go to another dealer and a Nissan tech came and of course it is normal. I do not think it is normal for your car to go from warm to cold again. I have also had a horrible clunk under the car when I go from the break to the gas again (someone heard it when I was stopped by them then took my foot off the break and went to the gas again and said something is loose under your car) but according to them it is normal and they even tried to tell me the clunk is in the engine.  Now onto the jerking/pulsating the car does when I am driving at 50 or higher and especially going up the hills/mountains it does it really bad. Again nothing.  There problem is if they can not duplicate the problem or it does not show on the computer they are to lazy to look into it further.  Well needles to say I have filed against Nissan with the lemon law and we go to court in November. And I will say save your time calling cooperate cause they do not care and will not help. I had to be a pain in the butt to get help. This process has been going on since the beginning of December ( mind you I got the car in October) and I still have a long way to go. It can take almost a year to resolve. I will never buy a Nissan again!
