We have a new 2015 NV 3500 that has been in the repair shop 40% of the time we have owned it as technicians work to figure out why we have hot air at 62 and above on the ac. We are sweating in our winter gear and can't cool down unless we put the ac on at 60 or 61. Certified techs had our vehicle code showing an internal heat sensor reading -42 degrees Fahrenheit for the interior of the car (which would make sense why it would be heating up then at 62) and replaced the recommend part. Now it won't code, but we still have really hot air at 62. All other NV's coming into the dealership are doing the same thing. Nissan needs to figure out a repair to fix this!
