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 of negative battery cable end at battery post. Solution: Wire brushed battery post, negative connector and put a thin film of automotive grease on the connector only
battery terminal post was cracked when car was new. never knew it..never had it checked...found out to late corrosion ate connector... lucky for me I had a GREAT mechanic who was able to reterminate cable with a little know how. or else I would of had to spend hundreds on new (2) cables..
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.
This has been going on since I bought the car and I purchase it new. I've been replacing the cable ends over and over and even the battery twice and the problem still exist.
Corrosion on my terminal and cable dealer is just cleaning it off. Which I find to be dumb now that I read this they should be telling me to change the battery!!!
Battery failed, replaced battery and cleaned up all visible corrosion and leakage.
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.
