This is very serious and dangerous after adding oil to the engine of this vehicle yesterday I made sure the hood was securly latched ( because it has come open on me previously while in motion ) I pulled up on the hood and it would not open. I left the gas station and got on the interstate.
Before consumer purchased vehicle they noticed that the air bag light was on, the dealer told the consumer they could not fix the light due to a federal law and never said the air bags did not work, there was an accident where the air bags experienced no deployment and 2 of the occupants injuries were soreness.
