Acid may leak from the battery at the cable connections, resulting in corrosion on the battery cable ends and in the battery tray. A Leaking battery should be replaced and the cables thoroughly cleaned or replaced if necessary.

I was told that battery cables had to be replaced as corrosion had backed up into cables. I was told this was not covered under warranty. Cables have been checked at each oil change, no problems until now. I was quoted a price of $622.00 to replace which includes labor. This repair seemed unusual for a car only 3 years old.
Corrosion virtually destroyed post clamps with the GM battery with less than 40k miles. Chevy doesn't sell the tiny post clamps except with a whole cable assembly ($200+). Going to rig something up myself as that's some bull, but for now my battery posts are not securely connected.
Car stopped starting. After investigation, discovered the battery terminals and completely corroded and ended in me having to replace the terminals and battery, to the tune of over $200.
Excessive corrosion at battery terminals for a car with only 50,000 miles. Battery will need to be changed and this is not an easy process. Very poor placement/design for battery. Have to remove factory braces, fuse assembly and headlight to remove battery. No a quick fix as is usual with battery replacement and not something that would be cheap to fix at repair shop either due to amount of labor needed.
