“Air bag dash light is on for seemingly no reason. It used to be intermittent, but it eventually stayed on. Mechanics and Hyundai dealership have no answers. It comes on as soon as I start the car and doesn't turn off until the car is off. I was told my airbags will not deploy in an accident. How delightful.”
NHTSA complaint #10948181, filed 2017-01, 150,000 miles“There is an electrical problem in my auto, which manifest itself when I switch on the electrical system. My headlights would come on normally, but inside the cabin the dashboard and all the other lights would start blinking on/off like the hazard light. The power door locks would also come unlock and when I checked on the external lights, the headlights would be steady, but the indicator (amber) lights and brake lights would be blinking. …”
NHTSA complaint #10594426, filed 2014-05, 130,000 miles“Your probe into the Hyundai Sonata airbag issue should be expanded to earlier models as we have a 2005 and what you are initially explaining affects our vehicle also. We have had the airbag light reset a few times by the dealer (zimbrik Hyundai in madison, wi). They initially stated that it was just a wire under the seat that needed to be reattached. They'd do that and turn off the airbag light, it'd be ok for a few months, then the light would come back on. …”
NHTSA complaint #10616748, filed 2014-07, 126,000 miles“Electrical issues began a month after driving the vehicle. Front and rear light bulbs continue requiring replacement, the dash light also will flash when brakes are depressed. The trunk leaked the first christmas, dealer claimed to repair it, but failed, still leaks. Air bag indicator came on, went off eventually, and is back on again. Finally, car began losing power last year and cutting off sporadically in traffic, and now the rear and window brake lights remain on when lights are on but not when turned off. …”
NHTSA complaint #10692184, filed 2015-03, 103,000 miles“Bought 2005 hyuandi on 12/8/04. Experienced vibration on 12/9/05 took car back to dealership in cleveland tennessee, they said nothing was wrong, but they thought that the bolts that hold the motor in car needed to be tightened. Took car back 3 days later for the same problem vibration, they said that the bolts needed to be tightened again. Took the car back on three other occasions and they continued to tighten the bolts that hold the engine in the car. …”
