scotty, 3.6L V6 2017 chevy camaro LLT (2LT) 46K miles. while driving down the road all my dash gages & lights went out...... following was a few days of trouble starting my car. i tested the battery, got 9 volts. went and got a new battery, installed and found all issues to be even worse, these issues include..... airbag light, stability control, side detection, park assist, seat warmers wont work, no readout on oil pressure or oil temp, no display for speed, engine rpm, fuel level, oil pressure, external temp, even the direction im traveling. i tested the new battery and found only about 7 volts. replaced the new "junk" battery and all the issues remain even after driving for an hour and turning the car on and off every 5 mins roughly 5 times in total.
Have you verified the vehicle is properly charging? You could be dealing with an undercharging condition. I would test the alternator and do a hard reset on the battery to give all modules a healthy reboot. Especially on gm improper voltages can cause very erratic and what may seem like unrelated concerns
Check the engine to body grounds make sure there's not corrosion or fraying. I've read in the camaro forum that has been the issue with many dash/enfotainment gremlins. Could be other things, but check the easiest first and go from there.
Definitely you have a charging issue. Load test the battery and alternator. Btw, did you reset the codes after replacing the battery?
i have checked the motor to body ground, its clean and SUPER tight, as well as the ground on the battery. i connected the cars ground to positive before installing the new battery to reset everything. so the best thoughts would be poor charging or a computer issue. side note, i have a guy just as good as scotty who thinks it might even be related to anti theft systems from grounding out all electricals. but everything is only speculation until the problem is actually resolved.
