  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

hello i own 2012 Hyundai Genesis 4.6 Sedan 126000 miles on it . battery light came on Suddenly. the multimedia screen intermittently says please turn engine on so battery doesn't discharge. Is there a separate voltage regulator??? and or is the voltage computer controlled???
 
Your alternator has failed.

I recently replaced the alternator in my '12, and it exhibited the exact same symptoms.

+1 on alternator failed. This happened to me last week. I have a 2011 4.6. I replaced it myself in my apt complex parking lot with a buddy of mine with one we picked up at a local parts store and its working fine so far. good luck!
