This is a totally preventable issue. But it requires popping the hood and looking at the fluid levels. If low either top off or take to the dealer so you can avoid this issue.My 2013 w/ 22k miles finally did the same thing. Fixed rather quickly with a coolant top off and reset of trouble codes. Only downside was that mine occurred on a Thursday and the dealer couldn't get me in until the following Monday at noon. It's my daily driver so almost 5 days of gas only killed my mpg.
Good question. They did not do that with mine but because I have to take it back next Fri as they missed checking for other recalls ... I will point out the "Preliminary Service Bulletin PI0961 | GM Document 3938762 | Service Update Campaign 14114" to them.Is this something that should be "topped off?" I would think it's a sealed system and would only be low of it was leaking?
My 2014 has almost the exact same mileage and today I got the message about servicing the high voltage charging system. I've scheduled an appointment for Saturday. I also have the recall notice that needs to be addressed for the reprogramming for the loss of propulsion message so hopefully they can fix it all at once. How did yours turn out?I also got the dreaded message on my 2014 with 82k miles. First time happened about two weeks ago. I had to pull my L2 charger out mid-charge to go do some errands. Since I only had about half charge, I ran the engine a bit on the highway to save battery for stop and go traffic I would experience later. After driving about 30 miles, I got to my location that has a free L2 charging and noticed that the warning had gone away. I charged up there and hoped things would be fine. Yesterday, same thing. I pulled out my charger mid-charge again. Soon as I got in the car, the warning was there. I tried doing the same thing, running on engine a bit, but this time the warning is staying. I checked coolant level the first time and it was just above the "line". My local dealer had no Volt appointments until next week, so I'm taking it in on Saturday for regular servicing and they said they would scan the codes and determine what they'll need to do when I bring it back next week.
I'm hoping its simple of course, either top off more, or maybe a bad coolant sensor. Guess it could be the charging port possibly. I read the codes and they are the generic ones.
I've been doing the same thing. The coolant level is fine, but I have to clear the codes every couple days. I assume since the coolant is topped off, this is probably a faulty coolant sensor and no damage is being done to the battery? Did you have any luck replacing the sensor on your own?My son has a 2013 Volt with the same problem. The car is out of warranty and the coolant level is not a problem. He has been using my ODB2 scanner to reset the codes. Can we just proactively replace the coolant level sensor? Worst case, the problem is not fixed.
Installing the defeat plug AFTER the latching codes have been set won't solve the problem. Somebody, you or the dealer, will have to do the reprogramming. Same for installation of a new sensor. Since the "sensor is nothing more than a reed switch activated by a magnet in the reservoir, who knows whether the bouyancy of the magnet is off or whether the mass of the reed is such that hitting a bump causes it to bounce, but I'm doubtful that new sensors really solve the problem.We installed the sensor bypass device and within a day or two the codes reappeared. Will probably need to reprogram the car firmware to fix this.

Try the Facebook site. They have a lot of program people thereI figured that it wouldn't hurt to install the bypass and that it might solve the problem. My mistaken reading of the problem based on the responses in the forum is that that stopping recurrence of codes that could be cleared would end the problem. I agree that there is not much point in replacing the sensor and using the bypass eliminates the sensor as a cause of spurious code triggering . There are other systems that would detect a problem.
I presume that at some point we will be unable to clear the codes. Or could it go on like it is now where we can just clear them. I would almost rather keep resetting the codes as long as that works and resort to the reprogramming only if we are suddenly no longer able to clear the codes. I wonder if anyone here has "bricked" their controller and whether that can be fixed by a dealer or requires replacement of the controller.
I'm just wondering now if I I should try to "rent" a reprogrammer from someone local vs purchasing one to save a little $$ and help someone else defray the cost of their purchase.
What ODB2 scanner are you using. I need to get one to reset my Code. This Coolant issue repeats itself ad-nauseum!My son has a 2013 Volt with the same problem.
