Selected complaints filed with NHTSA by 2003 Hyundai Sonata owners, lightly cleaned up (personal details are redacted by NHTSA).
Airbag light came on and stays on. Pulled a code that pointed to the wiring in the passenger seat. Moved wiring around and made sure connectors were properly plugged and the light went away for maybe a week. Light is back on again. Removed seat bolts to gain better access, used tubing and electrical tape to straighten any kinked wiring I could find underneath passenger front seat, disconnected and reconnected connections. Airbag light blinked once and still remains on with the code still pointing to the passenger seat wiring. Apparently this issue has been reported many times in online forums with no meaningful response from the company though this clearly affects proper airbag deployment.
We were involved in an accident and none of the airbags properly deployed it only fell out of the seat on the passenger side of the car and it deployed flat no air in it or nothing. My fiancee was injured as well as myself and we are currently being treated for injuries sustained by the accident...
The air bag light is constantly on, meaning that in the event of an accident, they will not deploy. Incredibly dangerous. This is apparently due to wiring underneath the passenger seat stretching and pinching from moving the seat itself and when things are placed underneath the seat that May disturb the wiring. I know it is the wiring underneath the passenger seat due to checking the trouble code and also being able to temporarily fix the issue for a couple weeks by gingerly moving the wires until the light went away. Now I can't get the light to go away no matter what methods I try. Can't find a replacement set of wires nor can I locate which wire specifically is being affected to try to fix the issue myself. I have seen dozens of people making this same complaint about the airbag light staying on. …

In 2005 while driving my girl friends 2003 Hyundai Sonata, I went to make a left turn of a main street in oakland, ca. And was hit by a 2006 Mercedes Benz own the passenger side. No air bags where deployed at all. $8.000 dollars in damage was done. Hyundai corporation never came out to look at the car, but ruled that the sensors acted properly. The car wa equipped I believe with front and side air bags.
Rear ended the vehicle in front at a stop light. The airbags never deployed. Now the airbag light is on in the vehicle. Repairs are $1349.00 replace the wire harness. I noticed this has happened repeatedly with these vehicles, why has nothing been done. This is a safety hazard, but the chrome wears off the door handle and a recall is issued. Something is rotten here.
