About 2 weeks ago, we brought our delivery vehicle 2013 Nissan NV200 in to get checked as it was not blowing cold air. Charleston Nissan charged us nearly $2500 to fix. About 1 week after the vehicle was supposed to be fixed a sharp burning smell was sensed when using the air conditioning. The vehicle was brought back and we were told that it required another $500-$600 fix. When we ask why this is happening we get the following answer. "parts break" "that is what extended warranty is for".
