2018 Enclave - Dead Battery - Malfunction Indicator Lamp

Cooper21 · Dec 27, 2022

My 2018 Enclave had a problem with a dead battery after 3 days in about 20 degree cold and wasn't driven. When I tried to start it yesterday, I got a click out of the starter, the windshield wipers cycled and the dash gauges went a bit crazy. Today I had AAA come out to jump start it. It did start right away and left it running for about an hour to charge it back up. When I went to drive it a while later, it started OK, but I had the Malfunction Indicator Lamp was displaying.

So, how can I reset it? The car has almost 37K miles on it. Do I replace the battery, tested or whatever? We are far out on Cape Cod and the nearest GM shop is a Chevy dealer about 30 minutes away. The nearest Buick dealer is about 45 minutes away. The manual says that an AGM Battery is the desired replacement. So looking for your thoughts or experiences??? Thanks

The battery should not have died after three days unless there was something running that shouldn't have been. Some auto parts stores will check your battery for free and also check and possibly reset the code, depending on the problem. Since you don't have a dealer nearby, I would start there.

You mean the check engine light, or the icon for the battery is lit up?

Looks like a sideways engine block - manual calls it Malfunction Indicator Lamp.

Malfunction Indicator Lamp went off - car seems to be running fine. But will take it to a local garage to do battery analyzer before springing for a replacement.

Time to replace that 4 year old Battery in my opinion…

I see your "join date" is 7/13/2017. If you joined this forum when you purchased your 2018 Buick Enclave you actually have a battery that is over 5 1/2 years old. It's time to replace that battery.

An hour of running it isn't going to recharge the battery. I suggest charging the battery with a battery charger.

IF that is the original battery, it's time for a new one, even if something was left on to drain it. As for the MIL (Check Engine Light) don't worry about it for now. There may be a lot of codes present due to low voltage, which is normal. Install a new battery, check the charging system and make sure you don't have a draw. Good luck.
