The vehicle was taken to the local mechanic to be diagnosed, and it was determined that the passenger's seat occupant detection sensor had failed and needed to be replaced.

While driving, a warning message appeared on the dashboard stating: "Supplemental Restraint System Problem. See Your Dealer." The airbag warning light also illuminated. This indicates a malfunction within the Supplemental Restraint System (SRS), which controls airbag deployment and seatbelt pretensioners. At this time, it is UNKNOWN what specific component of the SRS failed or malfunctioned. and this issue first appeared 2 moths after purchase but its been coming on and half i don't know how serious this is. This malfunction places my safety and the safety of passengers at risk because the airbags or other restraint features may not function properly in the event of a collision. The problem has not yet been confirmed or repaired by a dealer, and no inspection by the manufacturer, police, or insurance representatives has been completed as of this report. …
During normal driving - clear weather conditions - the car will suddenly activate the forward collision braking. It will literally slam on the brakes and decrease the speed by 10-15 MPH. This happened as I was going down the drive of our neighborhood, I was at 45 MPH with no one in front of me or behind me (thankfully) and the car applied the brakes and activated the front collision warning. There is also an intermittent issue with my seatbelt. Specifically the drivers seat belt. I was witness to someone driving my car - he buckled his seat belt and it unlatched. He then buckled it again thinking he didn't do it right - but it wouldn't latch. This has happened to me before as well - but usually after the third try of buckling the seat belt it will work and so I thought nothing of it. Additionally, the windshield wipers do not go back to their original position after being in use.
Brakes: Every day for past two years, on every startup car states Brake system problem, anti-lock brake problem, and TPMS problem; with it having no actual problem with brake system and message disappearing after a few minutes of driving. SRS: Intermittent display of SRS light while driving reading: airbag system or seat belt tensioners have a problem. Usually appears after Passenger airbag light intermittently turning on and off with nothing in front passenger seat. SRS light on dash doesn't come back on after restarting car. Issue did not appear until seat belt recall last year.

I keep intermittently getting a Supplemental Restraint System error. I have been on forums with other vehicle owners getting the same error. The dealer says it is a bad airbag while others are saying it could be two other less expensive remedies they have encountered such as a faulty cutoff indicator that gets overheated and the solders come loose as well as a faulty seatbelt buckle assembly. This is not a constant issue, it is intermittent and feel if the airbag was faulty it would be a constant error.
