“UNINTENDED ACCELERATION. WE HAVE REPORTED THIS DEFECT TO HYUNDAI DEALERS AND CORPORATE OFFICE TO NO AVAIL. U.S. TRANSPORTATION SECRETARY RAY LAHOOD, MARCH 2010, ANNOUNCED TWO MAJOR INVESTIGATIONS DESIGNED TO ANSWER SAFETY ISSUES OF UNINTENDED VEHICLE ACCELERATION FOR ALL MANUFACTURES.

Air bags
21 reports4 crashes
“AIRBAG LIGHT CAME ON IN 2011 AND WAS TOLD ENTIRE SEAT HAD TO BE REMOVED TO STOP LIGHT. COULD NOT AFFORD THE COST. RETURNED TO DEALER AGAIN IN 2014 AS HAD READ CONNECTOR UNDER SEAT MIGHT BE DISCONNECTED WHICH COULD BE CAUSING THE PROBLEM AND DEALER FOUND THIS TO BE TRUE AND SECURED THE CONNECTED AND THE LIGHT WENT OUT; HOWEVER, WITHIN FEW WEEKS, LIGHT CAME BACK ON AND HAS REMAINED ON SINCE. I DID NOT ASK THE DEALER ABOUT IT AGAIN, KNOWING I WOULD HAVE TO PAY FOR A MAJOR TAKE-OUT OF THE SEAT TO CORRECT. OVERALL, THE LIGHT HAS BEEN ON FOR AT LEAST 5 YEARS. I AM THE ORIGINAL OWNER. THE LIGHT CAME ON BEFORE MILEAGE WAS 51,131 AND MILEAGE IS CURRENTLY 83,486. I COVER THE LIGHT WITH ELECTRICAL TAPE AS IT DISTURBS ME THAT I CAN'T GET IT EASILY FIXED. I DOUBT IF THE AIRBAGS WORK BUT DON'T KNOW FOR SURE AND PROBABLY WON'T UNLESS I HAVE AN ACCIDENT OR A RECALL IS MADE FOR THE DEALER TO FIX THE PROBLEM.”
