Had an issue last week where the Spark wouldn't power on normally. This was on a 3 week old 2016 1LT w/DCFS at 800 miles.
The week prior had one instance of the battery saver active message come on and the "READY" indicator next to the gear indicator on the instrument panel wasn't on. A few minutes and couple of power cycle attempts later it worked fine.
Then one night after work the following messages and indicators came on when attempting to power on:
1. Battery Saver Active
2. Service Battery Charging System
3. Service StabiliTrak
4. Service Brake Assist
5. Service Airbag
6. Shift to Park
7. Low Battery
Those messages plus the corresponding indicators (Car with exclamation point, Car with slippery tracks, Brake with exclamation point, Airbag, Battery, ABS, and P with Wrench) would all come/stay on after they would have normally turned off after a successful power on. Even the "Shift to Park" message while the indicator showed as being in park.
This happened when my wife was leaving work to come home around 10pm and 20 miles from home. I went up to try a simple jumpstart which did not work, then we used the OnStar button to report the problem. They got a hold of Chevrolet support who worked on getting a tow service. Unfortunately the tow was going to be about 90 minutes out, and it was already after 11pm by the time we got to this point. Since I was going to have to bring my wife back to work in the morning anyway, we decided to schedule the tow for the following morning. Unfortunately I didn't bring a multimeter to see what the battery was reading.
The following morning the tow was extremely easy. The driver was right on time and only needed the key. Dropped it off at the local dealer and got a call from them a couple hours later. They determined it needed a new 12V battery and had to order the AGM battery to be in the following day.
This is basically the same story as found here: http://www.mychevysparkev.com/forum/vie ... f=7&t=3703
. While this doesn't seem like a common problem, it's definitely happened before. Overall I was pleased with the OnStar, Chevy customer service, tow service, and service center. Slightly annoyed with the battery manufacturer.
