 My wife purchased a 2015 Nissan Sentra SL in September of 2015.  The gas mileage never did get to where the dealer reported the gas mileage would be.  In March of 2016 at 7:30 AM in the morning a car ran a red light and tore the whole frontend off of the car.  Some the damage was done on the left side of the car.  Not one airbag went off during the accident.   I decided to talk to the shop people at the dealership and they gave me a number to call at Nissan.  I called and the guy gave me a 30 minute talk on why the airbags did not go off.  They took my message and about a week later a guy called and gave me the same spill about a head on collision to make the air bags go off.  Well what about the side airbags.  My wife has whip lash and a sore head where she hit the door glass.   I feel the car is not a safe vehicle.  The frontend of the car was complete destroyed along with the left side of the vehicle.  If you have to have a head on collision to make the airbags go off, then why put airbags in the side of the vehicle.
