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.
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.
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.
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.
