P2176 code chevy
My 2007 Chevy Cobalt LS started knocking after an accident and because the knocking wasn't coming from a collision problem the dealership didn't even look at it.

They looked it up and gave me a printout. At the time, it said one of the most common cause for my vehicle and this code was a bad battery. My Traverse has 166k miles now and we were still on the first battery.
