This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Battery connection leaked battery acid on the braking system tubing. The acid leaking onto the brake lines caused the brakes to fail. The dealer indicated that this was a common problem with these batteries.
Factory battery with side-mounted terminals leaked acid onto wiper fluid well mounted below it causing well to crack and drain. Dealer replaced the wiper well, but recommended I replace the battery as well. I replaced the battery myself (instead of letting the dealership do it) on May 17, but not before the old battery had once again leaked acid and cracked the new wiper fluid well. Old battery casing was not cracked or otherwise damaged; acid appeared to leak directly out of the terminals. This appears to be a design flaw by either ac delco for the battery itself or by GM for not properly isolating the battery from vibration. Furthermore, the foam "diaper" the old battery was wrapped in indicates that GM was aware of a potential leak issue for this battery. The foam does nothing to hinder vibration. Most of my 40000 miles are highway miles, and I seldom go off-roading (unless the potholes on the interstates of SC count).
