2018 Chevy Equinox battery dead

Asked by GuruNKS74 Nov 05, 2019 at 01:40 PM about the 2018 Chevrolet Equinox

Question type: Maintenance & Repair

I bought my SUV brand new. I've had it for a little over a year, and I've had
issues with it almost the entire time of me having it. the most recent being my
battery keeps dying..... This particular problem began 2 weeks ago. The
battery was dead to the point, I wasn't able to open the door (using key less
entry). I tried to have the battery charged twice and no luck. I finally (after 5
hrs.) was able to get a strong enough charge. The next day I took the truck
to the dealer with my concerns, 2 1/2 hrs. later....."Nothing's wrong,
everything tested fine, MAYBE it's the key fob". Nothings wrong?! Because
obviously I like being stranded in a cold garage all night after work. Okay
fine, "nothings wrong", 2 weeks later heading out for work in the morning.....
Truck won't start. AGAIN! I had it towed to the dealership so the can test it
and work on it again. I'm hoping I don't get another "everything is fine"
conclusion because there's clearly something wrong. Has anyone else had
this kind of issue? I really wish I had done my research before purchasing
the damn thing, but this will be my last purchase with Chevy and the
dealership as well.

if the battery is good and will hold a charge but keeps going dead you have a parasitic draw most likely.

Having same problem with a 2011 Equinox. Went to start it in the morning and nothing - couldn't unlock doors with fob, no lights on. Can't remove key from ignition after attempting to start. Jumped it and it started up and ran fine for a couple days. Went to start it again and same thing - fob won't work, no lights, no dinging sounds, completely dead, can't remove key from ignition. Called AAA to come and bought a new battery from them for $150. Everything was fine for about 5 days and then it all happened again. Jumped it, took to mechanic and he put a new alternator in it. Paid for alternator and went to pick it up after the shop was closed and it didn't start. Called mechanic in the morning and he "rebooted the computer system." Picked it up at 2pm yesterday and it was running fine. Sat from 4pm - 8pm and started right up at 8pm. Went to start it this morning and it was dead again. Jumped it and it the security alarm and radio came on immediately when the cables were put on the other car. It's back at the mechanic's now, but he is stumped. Any ideas?

My mechanic found the problem. Apparently, there is a known problem with the Equinox where the computer system malfunctions and the vehicle does not go into "sleep mode." So, even though everything appears to be off, the computer itself is still on. The solution is a new computer system, which for my 2011 is roughly $1100 new. My mechanic is looking for a used computer system, but in the meantime, he has installed an equalizer on the battery. This way, I can turn the battery off when the car is not being used for an extended period of time. He learned this from a friend who works at a Chevy dealership, so the manufacturer is aware of the problem.
