My 2012 chevy Malibu has a problem with the passenger air bag system. At random times the passenger airbag off light will turn on when the seat is occupied (by someone >120 lbs) also at the same time if the passenger unbuckles the seat belt the seat belt warning light does not come on. I have several videos of this failure while sitting still and while driving. Dealer replaced the passenger sensing sensor and control module. This has not fixed the problem. Dealer said because the passenger sits with one leg tucked under the other that this is the cause. Not buying it because it does not always fail like that. We have duplicated the problem at the dealership with the service adviser and the technician. I can get the system to reset by cycling the key to off and then restart the car. This is not the fix just the patch. Sometimes the problem happens when using the remote start and the passenger gets in before the key is turned in the ignition switch. I have been in contact with gm about this.
