Question about 2006 Chevrolet Equinox

Battery goes dead overnight

I have a 2006 chevy equinox with 6000 miles.  my problem is that the car battery dies overnight.  It runs the battery down so much we get no lights at all.  so I changed the battery and it still does the same thing.  I pulled the fuse for the radio and the car has no problems starting at all.  We have had no problems for several months with the fuse taken out.  the day after we put the fuse back in the battery goes dead.

    We did not know to go after the radio at first.  We took a volt meter and turned the car off and the radio had the most draw.  It was not much but is enough to make the battery go dead.  so if we leave the fuse in for the radio it will go dead overnight.  If we do not have it in we have no problems with it starting for many days.  
    We have the stock radio in the car.  Thanks for your help.

    We bought my 2007 Equinox 8 days ago and the damn thing has been towed to the dealership twice already because it will not start--no lights, no anything! This was the biggest pile of **** Chevy has ever made. Do not buy this vehicle unless you want to waste money and time! Seriously, I warn you DO NOT BUY AN EQUINOX!!!!

    Great job troubleshooting.

    How did you know to go after the radio?

    Is the radio OEM or Aftermarket?

Hmmm...I wonder if several Equinox's battery that lose voltage only happen on factory installed radios with XM OPTION ONLY ???
Newer Equinoxes (and Pontiac Torrents) now have XM and regular radio wires are combined into one antenna installed on the roof (just above the rear hatchdoor area)
My gut feeling is that IF the XM's wire is pinched by the left rear plastic trim's metal clip inside (the upper interior trim part is behind the left rear quarter window)
It MIGHT be the cause of the radio's 'short-circuit' if the tan-coloured wire is pinched onto the metal body frame....perhaps you could pry that trim part out carefully to check for XM's tan-coloured thin wire located there.
IF you wish to check this out, pop open the rear hatchback door and look for the plastic trim part located at the upper-corner between the left-rear quarter window and hatchback area.

FYI: it has 6 vertical metal clips behind the plastic trim part....ensure it goes back into place properly without bending it during reinstallation......IF you need to replace the XM's tan-coloured wire, the XM wire socket are connected from the rear roof antenna to the XM unit located below the interior left rear quarter window area.

Hope it helps!

Error code p062b 2012 equinox

Had the same problem on our 2012 Equinox today. Threw codes P026B and P062F. Appears to be a bad battery. Replaced battery and all seems ok now...keeping fingers crossed. My suspicion is that the faulty, dying battery caused a low voltage situation in the injector control module and thus those errors. Will see if the check engine light returns in the next 48 hours.

My stabilitrak light started going on. I replaced the battery. Today while driving my battery went from 14.6 volts down to 12.5 and then back up. What is going on?

stabilitrac is from balljoints prob on tire rods of sway bar and altonator runs at 14v and batt runs 12. for it to be dropping to 12 you need to run to auto zone n they can check your alt. or while its runnind take your batt post off batt n if it keeps running your alt is good and if it dies out rite away alt has to be changed

Over night, the 2006 Equinox won't start. Just clicks. There was not lights left on or anything. It also will start with jumper cables

hi, sounds like your car's battery is drawing down overnight( draining). First you need to check the battery's state of charge and its capacity to handle a load. (Get battery tested) If your battery checks out ok, you are dealing with whats called a parasitic draw.(This is a draw on the battery that is caused by an electronic device somewhere in the car, ie: computer and or module(s). To find the source of the draw use a low amp probe(with inductive lead) at postive battery cables and isolate each circuit till draw stops. You may possible be dealing with a intermitent parasitic draw if the battery does not go dead every night. IF that is the case you have to check every night after the normal timeout period ends(vehicle goes to sleep) usually 30mins or so, to catch the draw in the act.IF you do not wish to deal with this problem right away, you can by a quick disconnect terminal kit at your local auto parts store and attach to neg. terminal of the battery, in which you would only be required to disconnect terminal when you park for the night leaving the vehicle in a induced state of sleep.(No draw).

Would A 2006 Chevy Equinox with just 40,000 miles

Possibly. It depends on what the climate is like where you live. For instance, if you live in an area where the summer climate hits 110 (i.e. Phoenix), then your vehicle will need to be serviced more regularly. Best recommendation, take your vehicle to AutoZone, Checkers, O'Reillys, etc. for a free diagnostic check.

Battery died for no reason

About the only thing you can do is disconnect the battery and connect them again after 5 minutes. If that do not work check for blown fuse. Other than that then the XM radio has been damaged by the charger.

2006 chevy equinox sucks!!

How often are you driving it? And for how long of a distance? It is v very possible that your battery is just dying from sitting this does happen. Try an Optima battery for one. Then throw it on a trickle charger once a month to give it a full charge and you shouldn't have any problems. Then I would deal with it from there.
