Have you figured out the problem yet I've just recently started having the same issues I haven't replaced the computer yet my next step is to go through all the wiring and connections and make sure there's no corrosion and that everything is clean
I just bought a 2014 Chevy Cruze with 30,000 miles. I keep having the Service Battery Charging System light come on. When at a idol the battery voltage has 14.6 but as soon as you give it the gas the voltage will start dropping down to 12 volts and below. The alternator, surpentine belt, idler pulley, battery control sensor and pcm have all been replaced within the past month. Has anyone else had this problem and what can I do to fix it. I bought the car with the intensions of giving to my daughter for her 16th birthday.
My problem was the large fuse on the battery itself.
