Hello all, I am just wondering if anyone else has experienced a really strong, overwhelming odor, kind of sweet smelling, when you start your NV. I have had it into the dealer several times and they stated they could smell it then denied smelling it and said they can't find anything wrong with the vehicle. We are concerned something much more serious is going on. It only has 32K miles, 2013 model with 5.6 V8. It has also had a few issues with huge amounts of white/gray smoke has poured out after sitting a few days and a really awful smell. Car is now out of warranty so we are concerned it will continue to get worse and cause a huge issue down the road. It's running fine, no codes coming up??
