A D V E R T I S E M E N T S
Okay, since purchasing this vehicle (approx August 2022) I have had nothing but constant issues. This being only (what I would say minor out of them all). At first the trip button on steering wheel would seem to catch and I would have to double push it to finally get it to engage. Then the cruise control option was intermittent. Then I noticed the volume buttons trying to make a call. Again thinking maybe the age of the vehicle or possibly my aggression in pushing them to make them work. Now my horn doesn’t work. None of the buttons do absolutely anything. And after reading others complaints and their personal experiences I realized that my air bag light being on now for almost 2 weeks it all goes hand in hand. Why is every other year model of Sonatas with the same issues (all 9 of mine) being recalled and addressed except the effin 2011????? WTF HYUNDAI!!! Stand behind your product or GTFO the market!!!!
