Hi everyone ,
I have a new AWD SLT 2 w Nav coming in about a month(Mar 1) from the GM staff garage and while I was at my mechanics today he was saying the dealerships were having trouble with the batterys going dead on the Terrains if they were left for more than 3 or 4 days without being started, would this be because of the 4 or 5 different computers on board? Also he mentioned that GM insists on using a special battery charger that spits out a report of the amps etc after the charge. Also has anyone had there truck oiled or undercoated because I heard if you drill holes in your doorsill or doors it would void your warranty because of the airbags , this sounds a little strange to me. How do you guys find it handles in the snow? Thanks........Duck.

If the batteries are going dead in 3 or 4 days they weren't fully charged to begin with. There is a little draw on the battery but it should start after weeks of sitting and not being driven.

As far as undercoating. With the corrosion protection these vehicles get at the factory, aftermarket undercoating is unnecessary.

The holes in the doors are access holes for the oiling wand to penetrate inside for better protection, must be a canadian thing I guess, all of my vehicles have had this done , thats why my 1993 full size Blazer with custom mural and paint is still on the road.

Yep..that used to be part of the process here in the States years ago when rust protection was needed and popular.

Doesn't the terrain have battery rundown protection? or is that just for the lights. I left on the interior lights a couple of weeks ago and they shut off on there own so they wouldn't kill the battery.....I don't know if this is the same with the internal computer systems aswell?

It likely has run down protection (even my 2001 Pontiac has that). Last time I know, GM suggested dealers start new cars on the lot every couple weeks to ensure batteries didn't get run down as even with rundown protection there are parasitic drain circuits active all the time.

The Battery issue is being rectified by GM. You have to complain first. This all started (in my case) with a rear window defogger which would not work....after much checking it was discovered (!) that rear defoggers do not operate when the battery is below 70% efficiency. My battery was checked on several occasions by the dealer...it constantly read below 70%.(even after recharging) .so a new bigger and more powerful battery was ordered, and was installed.....all paid for by GM of course (the vehicle was bought in February 2010).Others on here, if you search thru "Rear Window Defogger" have had their batteries replaced...
It would therefore seem that GM original equipment batteries are not holding up well....so if yours discharges in 4 days...well....have the dealer check it out, and with luck, you'll get a nice shiny new bigger capacity battery if yours is defective......

When I was shopping for a Terrain/Equinox a few weeks ago, there was a Terrain on the lot with a dead battery. The key was in the ignition and you couldn't take it out with the battery being dead. It worked out good for me because I could bring my wife to the lot when they were closed and we could check everything out without being hassled. 5 days later when I picked up my new Equinox (they had to go find me the one I wanted) the Terrain was still sitting there dead.

My Terrain has been in storage (inside, unheated) since November 24. I have started it three times since then and it has cranked over just as quick as if it had been run every day. Now, I have kept it unlocked as I think the security system might be a culprit in draining the battery.

Ambient temps average about -10*C and have been down to -30*C on occasion.

This morning, my car wouldn't start after sitting for 2 weeks in the airport parking lot. The battery was dead. What a "nice" way to top off a wonderful vacation in Costa Rica. The guy from GM Roadside Assistance says he jumps them all the time. Anyone know which fuse to pull to avoid this happening ?

What a PITA.

Any new battery that can't handle 3-4 days of being idle is either defective...or there is a power leak somewhere on the vehicle. I'm probably not the best person to be answering this since I live in a "warm weather" (not so warm this winter until recently) state...but I think that most cars these days receive corrosion resistant coatings from the factory and it's pretty effective. As far as handling in snow, I've had plenty of experience the past two winters, and can honestly say that this is the best foul weather vehicle I've ever owned....and mine is 2WD.

Agreed - I plan to bring it to the dealer next week. A dead battery after 2 weeks is absolute BS !

Just curious as a new 2013 Equinox owner, less than one month.
We live in the north and occasionally a car's battery needs to be recharged during the winter months.
Looking at where the battery is in the Equinox, I was wondering how I would connect the battery charger.
I'm so used to using the + post and the - post on batteries of previous vehicles.

There is an auxiliary + Post on the right rear of the engine compartment, it is covered with a cap. You can pick up a - terminal just about any place that you see bare metal.

OK, thanks for the information. A rather unconventional method to me. Haven't bought a new vehicle in 10 years. A lot to learn.

My 2012 Terrain- I bought off the showroom floor, it too was dead, had to have them put a battery pack on it just to give me the actual mileage reading. It has been fine over the last 2 months I've had it in terms of holding power- even after it sits for a couple of days. With it being the showroom model, I'd expect it to be dead as people are in and out, opening doors, playing with seats, etc. When I was in my teens I worked for a Mercedes/Jaguar/BMW dealer, and even these high end cars...brand new and all- if they sat for 3-4 weeks without being started and run a bit, they too went dead. You will notice if you search on this forum people complaining about coing up to a dead car after letting it sit at the airport for 3 weeks (just as an example). Taking into consideration OnStar, alarms, clocks & radio memory, etc. this all draws power. I know if I were to ever leave it sitting for an extended period of time, I'd disconnect the battery or carry a booster pack. This can happen to any car- old and new.

- as far as oil spray and undercoating, as I too was considering this... if you plan to keep the vehicle for 10 years, it may be something to consider further down the road- as GM covers for rust and corrosion for 5 years.

- I have the AWD I4, I drove it through our biggest snowstorm of the season for 400 kms. from Windsor to Toronto, people getting stuck on the on and off ramps everywhere.... and this little beast was even better than my Explorer 4x4 in handling the snow. I will be investing in a set of snow tires though for next winter- It goes in snow, just doesn't stop well with the OEM Firestone tires. I'm on the road covering all of Ontario for my job- AWD was a must for this reason. 10 out of 10 in my opinion for handling snowwy conditions.

Congrats on the purchase of your new beast.... welcome to the quarky world of the GMC Terrain!
