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.Google+

Removed the battery cover and couldn't believe how much corrosion was surrounding the positive battery terminal!!! It was covering it enough that you could not see the terminal at all. Chipped the mess away and noticed a gap between the battery terminal (lead part) and the plastic casing of the battery. I am suspecting the battery is leaking. Unfortunately the corrosion was so bad it ate away most of the battery terminal. Negative terminal looked brand new.

Bought new OEM battery needlessly. Then found the corrosion which had ruined the end that goes over the positive post. Cut corroded end of cable off, which shortened it, and replaced with generic end. Will replace entire cable when a reasonably priced cable is found. Chevy dealer wanted $146.00 for the cable alone which is unreasonable. With labor total expense most likely could have been over $300. Generic end cost about $6.00 and was done for free where I get most of my work done. Shortened cable had to be re-routed and plastic cover may not fit back over battery.

My "service airbag" light illuminated so I took the vehicle to my dealer. Apparently, my battery and the battery cable is corroded so I need a new battery, new battery cable, and a reset on the airbag system. Total cost $462. Regular warranty expired at 3 years or 36K miles, and extended warranty doesn't cover any of it because batteries/corrosion are excluded.

Intermittent trouble turning over ignition. Dash light on for battery. Wiped out clock time. Took the dealer over an hour to see that the battery leaked, corroded the positive cable. Replaced the battery and used tape on the cable until a new one arrived from back order. It has now been 5 weeks and dealer says still no availability, even though every parts center on the internet has them on the shelf.

same problem. the car wouldn't start, after checking the battery I noticed the positive cable connector was completely corroded to the point that the connector came off by hand.

One day car wouldn't start. Checked the battery and it was packed with corrosion. Couple days later my car was hesitant to start and now the "Service Airbags" light is on. I'll be taking it to the dealership tomorrow and from reading the reviews will be out of pocket a nice chunk of change. Don't understand why this isn't covered under warranty and quite frankly find these warranties useless if normal wear and tear, which is expected, is not covered.
