2015 Hyundai Sonata Limited My BSD, ABS, Traction Control lights, along with the Auto Hold and check engine light (solid) keep coming on and my SCC won't work. They sometimes will go off if restarting the car but they are on more than not making those features inoperable.
I have 126,500 miles on it
Have you taken it into a workshop to get an OBD2 scan on it to see what fault codes are being generated? Having multiple systems go out on you and a check engine light at the same time sounds like a module has failed.
Can you try an auto parts store? Some have a driveway service where a store employee comes out and plugs in a code reader and provides a print out of the diagnostics. I live in Oz so I'm not familiar with how businesses like O'Reillys etc operate in the US, but there has to be an alternative to the stealership...
When you get the codes and find out what caused the driver assist features to malfunction, please post up the info as it will go a long way to helping other members if they have the same/similar issues.
