I've only had my 2012 Cube for 2 years and it has 45K miles so I can't really answer your question yet. I will tell you that Nissan makes well engineered vehicles. My ride previous to my Cube was a 1994 Nissan 5 speed, D21 Hardbody Pickup. I bought it in 1999 with 40,000 miles on it and sold it with 285,000 miles. I owned it for 22 years and during all that time I only had to replace the alternator myself at a cost of $89. I only had to have the AC charged once and It was still putting out ice cold air when I sold it (I live in Phoenix, AZ, land of 115 degrees). Immediately after buying my truck, I changed the oil with Mobil 1 full synthetic and while I had it changed the oil every 6K miles. I paid $6,000 for that truck and sold it last spring for $2,250 (not a bad investment).
When I bought my cube I also immediately changed the oil to Mobil 1 and since it has a 6 speed manual I even changed the transmission oil to Mobile 1 75w-90w Full Synthetic gear oil. I expect my Cube to outlast me since I'm 70 and I'm OK with that. If you keep up with the maintenance Nissans will last a long time. If yours has a CVT, the regular fluid changes are a must, not a choice. There's a lot of discussion on this site about CVTs and to replace one will run you over $4,000. Treat your Cube well and it will treat you well.
Good luck my friend
