2011 Hyundai Sonata driver assistance problems

Filed Jun 25, 2026 · Driver assistance, Electrical · FL

Randomly all controls on my steering wheel (I.e. cruise control, volume for sound, Bluetooth phone controls etc) just stopped working. Now I cannot control the radio, phone or even toggle to see mpg, mileage driven, use cruise control etc. I read there was an extended warranty regarding this issue and my vehicle was or is affected. However it has since expired and upon contacting local dealership they did not even have the parts for that recall.

I bought my vehicle from a local dealership a week ago. The horn and none of the features on the steering wheel work. The front panel of the steering wheel feels lose. I also smell gas often and my left muffler smokes and I sometimes smell burning rubber. Navigation does not work as it should and my xm features don't work because of a bad xm antenna (shark fin.) there is vibration in the steering when braking. My tire pressure light blinks and then stays on. The key doesn't operate the locks sometimes.

Ever since I had a new engine put in my car, my car hasn't been the same. It acts like it doesn't want to go when pressing the gas pedal right after (was told it was the eco mode), then my dash started to crack, now is extremely cracked which has an air bag, gas gage has a mind of its own, burning a severe amount of oil a week so there is no point in 'changing the oil', oil light never once comes on letting me know its low, no oil on my driveway or under the hood, interior dome light sometimes doesn't shut off, the brake lights short out on a monthly basis and get pulled over by the cops all the time. Now with only 50,000 miles on the 'new engine', I take it back to the dealership because its smoking when I crank it, doesn't accelerate sometimes going down the road when I press the gas, then starts smoking, headlights flicker, engine light stays on and low tire light stays on (even after getting new tires & alignment). Took it in yesterday, hyundai is stating my oxygen sensors, catalytic converter & gaskets and intake manifold need to be replaced at $3,177. The car isn't even worth that much. This is not the reason why my car is using excessive amounts of oil, smoking when I crank it and acts like the engine is about to blow up. Then they come back to tell me it needs the above, plus an engine replacement but out of 'goodwill' they will only charge me 20% ($2,000) with no loaner car. Its going on 3 weeks now. The corporate office is useless and very rude. I have a voicemail stating 'this is the highest customer service department and once the decision has be made, those decisions are fianl and its up to you to decline or accept our offer.' it's the engine, again! Which then lead to other issues! I will never buy another hyundai again!! This car has caused nothing but money and time, complete waste of junk!
