Awesome advice and thank you. The battery is no more than 2 years old so i think im covered except it is an optima red top so would that cause any problems? Also the terminals were cleaned and tightened and corrosion inhibitor was added about 3 months ago so i will double check, you cant always trust the dealership. But as of now i havent had a repeat of the light and have no problems. i have a diagnostic program on my comp. and i ran it while i drove and nothing out of the ordinary. idk i still love my baby.
