I’ve purchased a used 2015 Spark EV. At best, range has stated 64 miles after driving it off the lot. Now only two months later, it only will charge to 55.
I live in rural Northern California and charge daily due to my commute. Vehicle history shows it has only been owned in Monterey, CA area.
It has less than 28,000 miles.
Definitely feeling like I need to trade this in before it gets worse. I’m a new EV owner but I am aware of the variables with charging too frequently and driving habits.
I guess my main question is... at what point does this become a warranty issue? Will Chevy consider this a warranty issue? Perhaps EV wasn’t the right choice for my situation?
What’s up with the capacity of these batteries if the mileage is so low yet the capacity is so dramatically poor?
Finally—any idea how much a battery replacement would be out of pocket?
The first question that comes to my mind is are you using the car's heater in cold weather? If you are, you should expect significantly lower GOM range values. Second - find another Spark EV driver close to you who can measure your battery capacity using TorquePro. Or, you can estimate your battery capacity using the data displayed on the Energy Information screen in your car.
1. Charge the car to 100%
2. Go to the Energy Information screen (LEAF button) and reset all values to zero.
3. Take the car out for a long drive.
4. When you return home, go to the Energy Information screen and record the values for Kwh used and the % values for DRIVE, CLIMATE and CONDITIONING. Divide the KwH Used value by the sum of the decimal values for DRIVE %, CLIMATE % and CONDITIONING %. This will give you the estimated battery capacity. Try to drive so you minimize any regeneration.
GM Parts Direct lists just the HV battery at $24000. plus who knows what for labor and other necessary parts. I hope some business will come along to rebuild the HV battery.
I believe both the 2015 and 2016 Spark EVs use the same HV battery. For 2015 and 2016 Spark EVs, I believe the warranty requires that you have 40% or more battery degradation.
