2007 CHEVROLET AVEO User Comment / Complaint

Passenger air bag off light does not go off with someone less than 150lbs and is intermittently going off with a 185 lb passenger meaning air bag will not deploy. took to dealership and service department put several people in passenger seat weighing from 140lbs to 230 lbs. 140 lb passenger did not make passenger air bag off light go out. service department states " advised by tech assist engineers looking into issue" was told by service department they would call me with some answers. no calls for six weeks, when i called them back service department states" it's out of our hands and we can't do anything about this and i can call gm customer service". called gm customer service, and after two weeks back and forth phone calls was told by gm customer service and dealership service manager there is nothing that can be done as it is within specs. i asked where i can get a copy of these specifications for weight limit on air bags and was told to call gm. called gm asking for weight limit specifications and stressed that a 140lb passenger should be protected. gm representative states " we don't have the specifications and you may want to contact nhtsa. so this is what i am doing. aveo has less than 3000 miles. i would love to just sell the car but morally and ethically i can't. i'm really tired of fighting this battle. please help!
