Air bag light comes on without car being in any type of accident. Dealer wants to replace the entire control module. When researching this online, a tremendous amount of Hyundai owners are having the same issue.

The contact owns a 2011 Hyundai Sonata. The contact heard an abnormal noise progressing from the area of the engine. The dealer (gurley leep Hyundai, 5302 grape rd, mishawaka, in 46545, (574) 258-7700) was notified of the failure and diagnosed that the engine assembly needed to be replaced. The manufacturer was notified of the failure. The contact experienced the failure related to the unknown manufacturer's engine recall, but the dealer refused to provide a solution because the vehicle was excluded. The vehicle was included in NHTSA campaign numbers: 16V340000 (air bags), 15V759000 (service brakes, hydraulic), and 16V190000 (steering). The approximate failure mileage was 105. Parts distribution disconnect.

2011 Sonata, car burns oil to black immediately. Took car in on warranty service for front knocking noise that appeared to generate from steering wheel. Replaced left transaxle, still noise took it back they replaced right transaxle. The issues with electrical still exist they've replaced the left side buttons on steering wheel even though I complained none worked correctly. Now cruise control is nonexistent. The airbag light came on at 73000 miles. Seat doesn't go all the way down. There is a definitive rattle originating from the engine and at times the rear end seems to have drag and shake. They inspected car for recall and of course they said my vehicle is unaffected but who knows how thorough their inspection actually is. I mean they represent Hyundai so why would they want to say it was bad prior to any breakdown. Right. I feel like this severe of an issue should have an independent inspection.

Takata recall. The contact owns a 2011 Hyundai Sonata. While the contact was approaching a yellow traffic light, the preceding vehicle accelerated and then made a sudden stop. As a result, the contact rear ended the other vehicle while driving 55 mph. None of the air bags deployed. The contact's head struck the steering wheel upon impact. The contact sustained pain to the knees, elbows, and minor bruising. Medical attention was required. A police report was filed. The insurance company repaired the collision damages, but there was no investigation as to why the air bags failed to deploy. Months later, the air bag indicator illuminated and, a few days later, the contact received notification of NHTSA campaign number: 17V152000 (seat belts). The dealer was to schedule an appointment and indicated that the contact would need to have a diagnosis prior to the recall repair. The manufacturer was later notified of the crash and recently stated that the notice was received after the crash; therefore, the contact was waiting to determine if the manufacturer would assist. The failure mileage was not available. Parts distribution disconnect.
