2019 Hyundai elantra
The radio on my 2019 Hyundai elantra went out all of the
certain so my screen no longer works I've tried pressing
the reset button above the power button it doesn't work
also the lights on the car continuously go off and on and I
had to get out of the car and hit them for them to come on
now keep in mind I just bought this car still under factory
warranty Could this be a grounding problem and if so how
do I fix it
