Hey guys,

I have a 2013 volt with about 23k miles. I have been getting this "battery too cold, need to plug in" alert every couple of days. It's very transient and seems to happen at any random time. I'm also getting check engine light on which seems to go away after a couple of days. I imagine these two things are related. Every time I have called onstar to get codes they have not been able to communicate with the care. They then proceed to transfer me to tech support and I proceed to get dropped. I have researched this a bit and seems to be a faulty temp sensor. I want to get this fixed before something major happens and I get stranded. My question is: would this be covered under the drive train warranty?

Of course it all depends on what the issue turns out to be, but if, as you suspect, it's the temp sensor, a part of the battery pack has to be replaced. So obviously part of the drive train.

FYI GM has been more than fair with warranty claims. Just make sure the dealer understands the issue.

If it is a fault, that is if the battery is really not too cold, then it should fall under the Voltec warranty. What's the weather been like, and have you been plugged in?

Thanks for the quick replies, it's Florida so the temps here get no where near cold enough for this light to come on. Any idea why the car can't communicate with onstar? The car itself is running just fine. No loss of range or anything.

This smells of a bad temperature sensor within the pack. I had the same issue with my wife's car. Bring it in and they'll read the codes and likely replace a section of your battery (the sensors themselves are not easily swapped). All covered under the 8 year Voltec warranty.

My 2015 couldn't communicate with OnStar.
Bad OnStar module. It was replaced.
Bad stuff happens.

Can't communicate with OnStar or OnStar can't get the codes? If the former then you have to look at the OnStar module. If the latter -- and I assumed this is what you meant -- then this seems what happens when the temperature sensor fails.

Getting this message in FL is guaranteed to be in error. Temp sensor on the fritz.
