Air bags
43 reports14 crashes
“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.”

“The contact owns a 2003 Hyundai Sonata. The contact stated that while the vehicle was at Valvoline for a service appointment, the contact was made aware of NHTSA Campaign Number: 09V124000 (Suspension). The vehicle was taken to the dealer, who informed the contact that the subframe assembly and additional unknown parts were not included in the recall repair. In addition, the contact was informed that the recall could not be performed because other repairs were needed prior to the recall repair. The vehicle was not repaired. The contact stated that the vehicle was unsafe to drive. The manufacturer was made aware of the failure, and a case was filed. The contact was informed that the repair was not covered under the recall. The failure mileage was approximately 170,000.”
Electrical system

“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. THIS NEEDS A RECALL SINCE THIS CAN EASILY LEAD TO DEATH SINCE THE AIRBAG WILL NOT DEPLOY TO ATTEMPT SAVING METHODS TO PASSENGERS. LIGHT WAS ON FOR THE PREVIOUS OWNER FOR I DON'T KNOW HOW LONG AND HAS BEEN ON FOR ME FOR ALMOST A YEAR NOW.”

“THE CHROME ON THE INTERIOR DOOR HANDLE OF DRIVER SIDE EXHIBITED A CRACK AND SEPARATED. MY WIFE CUT HER FINGER ON THE CRACKED CHROME PLATING. I CONTACTED HYUNDAI CUSTOMER ASSISTANCE CENTER AT 1-800-633-5151 AND WAS TOLD THAT MY VEHICLE WAS NOT INCLUDED IN THE DOOR HANDLE RECALL (I.E., NHTSA CAMPAIGN ID NUMBER: 09V171000). I DON'T UNDERSTAND HOW ONE VEHICLE CAN BE RECALLED WHILE OTHERS OF THE SAME YEAR AND MODEL ARE NOT. *TR”
