I have just reached one year with my 2012 SL AWD version of the MO. I thought I'd relate a few of my experiences that have been for the most part positive since we see a lot of threads mainly asking for help with problems.
Firstly, I have been impressed with the smoothness of the vehicle. I owned a 2005 Maxima for 7 years and I can tell you the drive train on the MO, with the CVT, is so much smoother than the 5 speed automatic I had in the Max. The ride is much more compliant, and being an old guy, I especially like the higher seating position.
Although the gas mileage can't match what I was getting in the Max - 29 highway and 20 in town, I'm pleased with the mileage in the MO. It has exceeded the EPA estimates giving me 18.5 around town and 24.5 on the highway. Losing a little mileage and gaining tremendous utility in the MO is worth it to me.
People seem to either love or hate CVTs. I may not love mine, but it's a very strong like. It's really nice in the hills of WV where you don't have the constant down & up shifting you have in a normal automatic. It may not have the off-the-line scoot of the Max, but it's a much heavier vehicle and it does just fine for an old guy like me.
It's all not a love affair with me and Nissan. I don't like how they package their options, and for a $40,000 vehicle I think there are some things missing that you find on other vehicles at that price. But I knew that going in and I still like Nissan's 3.5L engines.
One place that I am pretty disappointed is in the OEM tires Nissan used on my MO. They are Goodyear Eagle LS. I have 8000 miles on the car and they are already down to 8/32". I don't see me getting more than 20,000 miles out of these tires. And I don't think they handle that well, and are not that great on slick roads. I'll be looking at something better come time to replace them.
So that's my take after a year in this car. Would I buy another one? That depends on how they are going to change the MO for Gen 3. I like it as is, but I'd like to see an upgrade particularly in the technology. My neighbor has a 2012 Ford Edge Limited, and he has a lot more technology in that car for a few thousand less than a MO. And he has more cargo room. BUT, it's a Ford...enough said on that subject!
If folks are considering buying a MO, I would definitely tell them to drive one. They are very nice cars, and although you hear a lot of horror stories on this Forum I actually feel the MO is not apt to be any more trouble prone than the typical car, and probably is better than most. I can tell you it's a LOT better than my Ford. So, I definitely recommend it.
