Dead battery


Asked by Aug 30, 2015 at 05:10 PM about the 2014 GMC Terrain SLE2

Question type: Maintenance & Repair

After being gone for 6 days, I went to start the Terrain.  No battery life
anywhere. No interior lights, no start, no fob working, nothing.  AAA tested the
battery and said it had only 4% life. Jump started right-away and ran. Charging
system was good on AAA tester.  Took it in to the dealer, and had a full scan
done.  Nothing wrong could be found.  Battery was low, and charged full.
Battery tested good.No excessive draws when off, only 4 ma. which is normal.
All cables tested good.  No explanation on their part as to why. Nothing
changed or adjusted or corrected. No issues after two weeks.  I had just driven
the car on a 250 round trip three days before we left, so no excessive short
drives.  Anyone have this problem?  Solution? Car has a 10 minute system
disconnect if any lights left on.  That is working. When started, all interior lights
checked and they were off.  I had not turned off the radio, but it turns off when
the door is open and turns off after 5 minutes on it's own.

The vehicle, including the battery, is still under warranty. If it dies again, call GMC roadside assistance. They'll tow it in, at their expense. Sounds like the battery is weak. Batteries installed in new vehicles are only rated for 3 years. Depending on when your Terrain was first bought, you could be coming up on the 2 year mark. It won't be a free replacement but you'll get money off if they have to replace the battery. If it happens again, I'd insist on a new battery. Since everything else checks out ok. HTH. -Jim

It is still under the 1st year warranty. The dealership offered to have it towed at their expense, but I told them I already had called AAA to jump start it. Since I pay insurance for it, why not collect from AAA? As it was, it started. The battery was tested, and even thought it is still under the new car warranty, I was told it tested all cells good. They did a slow charge on it to full charge, and tested it again, but no failure. I was told the machine they hook up to it is nicked named R-2-D-2 as it runs and checks every theatrical cable, device and equipment that can be tested. The mechanic also checked all the cables for cut cables or lose connections and found everything to be good. We'll just have to see if it happens again. I just wanted to know if anyone else had that happen. Very strange indeed.

I understand where you're coming from. However, I always recommend that people call roadside assistance while still under warranty. This way the dealer can't try to void your warranty coverage because someone else (AAA for example) "tampered" with the vehicle. HTH. -Jim

I also understand where you were coming from, but my first call was to get the vehicle started if I could. AAA did so I didn't have to worry about towing. I'd already spoke to the service writer and he told me to use GM as a tow. By that time the vehicle was running. IF there is a next time I'll do just that. Thanks for the heads up..

I purchased 2014 Terrain 3 wks. ago from GMC dealer. I'm not driving it much because I'm driving my other car that I'm trying to sell. Anyways last night the car won't lights...nothing...DEAD?? I can't believe this happened on a fairly new car...16k miles

smoke, if it is under warranty, like I was told above, have GM tow it in and have a full diagnostic done. I was asked if the car was subjected to a lot of short drives, not giving a chance for the battery to fully charge back up. I had driven it on a long drive a couple of days before leaving it set for a week. Ask if the alternator is not strong enough to give it a fast strong charge? Now if the car is a used one, the battery guarantee is only for one year after the initial purchase. If they try to tell you it is a battery issue and try to sell you a new one, compare the 4 or 5 year battery guarantees with what they want to sell you. Also insist they replace it since you just bought it and don't have many miles on it. Then take the supposed cost and tell them you'll either get your won \battery and they pay the cost of the replacement they wanted and you pay the additional cost, which will not be much. In my Corvette, I just got a fully 5 year guaranteed battery for $85.00.


I had this problem in the middle of August, and even though the dealer did a complete check of all the systems and battery, nothing was done. I have not had any reoccurrence of the problem. Sometimes electronics are a head scratcher. I'm getting ready for a 3,000+ mile road trip and have no qualms of having any issues. The battery sure should be charged when I get home for sure.


Just returned a week ago from driving 3347.3 miles and averaged 30.7 mpg. No issues and the battery is fully charged. Drove in 100+ to 21 degree weather and in pouring rain. No electrical issues at all. I'm having a hard time finding a clothes rod to fit in the rear seat area. The hangers in the car are made of weak plastic and give after a few hours. Other that that and the four cylinder is gutless when trying to pass, no issues. It needs a turbo diesel. Good power, great mileage.

Exactly the same problem here. 2015 Terrain left parked for 10 days - dead battery but no detectable reason. Never had related issues. Obviously something draining the battery...

My 2013 terrain will not start. It's ticking and is hard to get the key out. Is this my battery?

I've also had problems where the car dies when I put it into gear at first start. The dealer says there's nothing wrong with that.

Had kinda the same issue with our 2012 terrain. We were driving it for about hour and a half and stopped somewhere and shut it off. We came back out about 10 mins later and it wouldn't start. Acted like a dead battery. Got a jump and it stated right up. Took it to dealer and after about half a day of checking. The only thing they could find wrong was positive battery connection was a little crooked but tight. Had been arching and caused a bad connection. They cleaned it and it worked just fine. Year later we're having the same issue.


I have a 2012 GMC Terrain that I purchased last year same problem. I go into the grocery store come out and dead. It has been happening randomly glad to see it's not just me. Has anyone found a solution to this issue?

As far as I know, nothing has been posted as of yet. It may be a bad battery. If you have to replace it, I might suggest getting a top grade battery that may have more staying power. Check all the connections to make sure you are getting a full charge while the engine is running, and the alternator is putting out what it should. the relay also may be at fault. GM has had issues and a recall on ignition switches, perhaps the problem may lie there? If anyone knows, please post. I am going to jinks myself and say, since two years ago, I have not had a repeat of a dead battery. Nothing was changed as far as I know at the dealership, but it tested fine, everything was working as it should.

Ok guys and gals, My wife and I were gone to Europe for over three weeks time. My Terrain sat in the driveway in 110+ heat for a week, then it cooled down to 90 degrees the rest of the time. I feared a dead battery again. I got into the car on the 28th day and it started right off. No issues, just dust from sitting so long. Don't know what the dealer did two years ago, they claim nothing, but I haven't had any issues after the third time it went in and had full diagnostics done. Anyone else have the same solutions? All of a sudden after the dealer played with it, claiming nothing was adjusted or changed, no more issues? Let us know, yea or nay.

Hi, guys, I am the proud owner of the 2014 Terrain and I have been having some issues with starting also, and it is confusing the shit out of me, sometimes the car will sit for 8 hours and when I return it will not start. like you I have taken it back to the dealer and every test was run with negative results. Then there are times it will go for weeks without an issue. I believe there are some electronics on the car that do not shut down after the vehicle is turned off is that possible?

Guru51L26, Not to sound like a smarts, which zI can be, but you're guess is as good as anyones. It is possible, and after three complete tests done, I have not had an issue in quite some time. There are several messages on here that state the same issue. For some reason, it appears to be an issue from 2013 to 2015. It is a frustrating issue. I have not heard of other GMC or even Chevy having the same issue. If anyone out there knows if it is, let us know.

My wife has been having the same issues. Car will work fine for a month then dead. jump start and good again. Finally have to change battery out because this has happen so many times. I was told there is a software glitch with the bluetooth. If you are on the phone when you turn off the car the bluetooth remains active and drains the battery. I can't verify this anywhere. I'm going to try new battery and see if that helps.


Guru52DWF, thanks for the insightful information. That may be the reason everyone is looking for. So I'll have to turn off my WAVES when arriving at my destination and close down my phone before turning off the car. "Excuse me mom, I know you're going an emotional drama right now, but I have to hang up because I want to turn off my car. I don't want to also kill my battery." So be it.
