Trouble free for right now. Very impressive when towing, since it has rear air system with the tow package that absorb any trailer jumping. Driving carefully I get about 15 miles a gallon in the city and as much as 21 in the hwy driving with cruise control at 75. Remember that the Armada has a 5 speed transmission that will keep the vehicle RPM lower than 2000 at 70 miles a hour. So far I love my NISSAN ARMADA.
Very responsive powerfull engine. Easy to drive anywhere since rear sensors help in backing up.
