I've seen a lot of posts about factory AC-Delco batteries falling down on the job so to speak. In almost all cases it can be traced back to a vehicle that has sat on the dealer lot for some time without being charged at least every once in awhile before purchase. A diesel with it's higher amperage demands would only magnify that, diesel p/u's generally have 2 batteries in parallel for starting. I've used AC-Delco batteries all my life, can't remember using another brand other than for my lawn tractor, minimum life I've gotten out of them has been 5-6 yrs, got 10 yrs out of one. In any battery one might buy, be sure to check the date of manufacture found on the top label, buying a battery that has sat on a parts shelf for months collecting dust will guarantee you short battery life.

garagerog, unfortunately that can't be said about ours. It was delivered to a dealer in GA, was one of 3 new Terrains he just got in, went down to buy the Satin Steel couldn't reach an agreement, went to our local dealer the next day to see if they could work out a dealer swap with the other dealer for the Satin Steel. they wouldn't swap that one but agreed to swap out our Blue Steel. It never really sat on a dealers lot very long, don't know how long it may have sat on the plants staging lot.

You know how hot it's been in the Upstate SC, 90+ with high humidity and we usually do a lot of short trips with A/C on. Don't know if that could have caused the problem, but we've been driving like this for close to 15 years.

Just a bad battery it happens. Just like the other guy said about computer parts. I work in IT and we had brand new drives die in a day we have some that are still running after 10 years. It just happens. The auto stop in these cars use a different battery than in a car without auto Stop. They can handle the start and stop but if cell is weak or bad one day it will go. Its still rare to happen but it does. I bet its less than 1% fail which is a very good failure rate.

I recently had the same problem in my 2018 Terrain (less than a year old). It was a bad cell in the battery and the dealer replaced the battery. This is my third Terrain and have never had any problems with any of them except for this one. Not pleased the Terrain has only 3,000 miles on it and less than a year old. I hope this is not a sign of things to come because it was a major inconvenience.

I have looked at the battery on our new Terrain Denali and for the 1st time in my life, it looks like something I wouldn't want to change on my own. There's those plastic boxes on top of the battery with distribution buses everywhere and numerous connections to both positive and negative terminals. I can't see how to get one of the plastic boxes off the battery w/o damaging it or the clips that hold it in place. Also there's a large heat sink on one side of the battery. The whole setup is mind boggling to me. These batteries are AGM which are much more expensive than a typical flooded lead acid car battery. I assume AGM is needed due to large electrical demands including the start/stop system. Times have changed. Not sure if places like autozone would even offer their free replacement service once they look under the hood. Whatever you do, don't replace the OEM battery with an off the shelf "regular" car battery, it won't last very long. I put ours in L9 to defeat the start/stop "feature" so there is less wear and tear on the engine/starter/transmission/battery whenever I drive it. Unfortunately I can't get my wife to do the same.
