Question about Hyundai Sonata
HI! It's definitely a ground issue. If the BCM is not faulty then you may need to add an additional ground. Since battery and alternators are new there shouldn't be a problem. Have an additional ground installed and you'll be good. Hope this helps and thank you for using FixYa!
