2014 terrain slt my battery randomly dies on me also. the dealership told me it was the cell phone charger drawing to much amp. 7map. they charged it for me and told me it wasnt a warrenty issue and
dealership said cellphone charger was drawing to much 7map. they fully charged battery and i took car home. today i put a new cellphone charger in the power outlet and it drained the battery???? now my backup camera is shutting off by its self when backing up. the car has started again but i can tell the battery is low because it is hard to turn over. Is there an electrical issue with the terrains that gmc is hiding and wont admit to because of the scare of recall
There must be some short somewhere or some other electrical issue. It is possible that battery is faulty however.
Fully charge the battery then have it load tested. Your battery may be worn out. Typically the original battery is only designed to last 3 years. So if your Terrain was made late in 2013 you may be due for a new battery. A cell phone charger should not kill the battery. When Hurricane Sandy hit and I was without power I charged my phone on a regular basis for 3 days without the car running and it didn't effect my battery. HTH. -Jim
thanks i will try another dealer about the battery.
You're welcome. Glad to help. -Jim
I have a 2014 Terrain, and three times I went to start it and the battery was fully drained. I had it jump started by AAA and they gave a quick test. the charging system was good, the battery, although low was good, and they said it appears a light was left on to drain the battery that quick over night. Three times the dealer rand a full diagnostic check and could not find any issues. The first time, I had driven it 40+ miles away and then back so the battery was charged. the battery was tested and it was good, all the cells were holding charge. There has been other terrain owners with the same issue on this posting. We used to have kids taking gas from our cars, now maybe they are taking electrons from our batteries? I really have no answer. If your phone charger is not connected to a phone, it does not draw any charge. It is a minimal draw anyway. I think it is a design flaw in the computer system. All my lights are set on auto turn off after a few minutes so it is not that. The radio turns off when the door is opened.
