EV Battery
What Owners Say
"The battery started to noticeably lose capacity right after the 10-yr. warranty on it expired. (Surprise!) It is now down to 80% of original charging capacity/driving range, so it's still usable, but it's now dropping about 1 mile in range every 2 to 3 months. I'm going to try to have the battery pack replaced, soon. The dealer wants $10,000 to do it. But the car is otherwise in excellent condition, and if the replacement quote is for a new rather than re-manufactured battery (dealer didn't specify) it would be worth it to drive the car another 10 yrs. A local third party shop wants the same $10K to install a re-furbished battery pack with a 36-mo. warranty, or $5K for the same with an 18-mo. warranty, which tells me the refurbished battery packs fail much quicker than a new one."
Anonymous, MD (2014 Chevrolet Volt None 1.4-L 4 Cyl plug-in hybrid)""The Traction (hybrid) Battery has two cells that are weak, and the Battery Management System is unable to properly balance the voltage of all 97 cells. I have been clearing the Diagnostic Trouble Codes to allow the car to be usable. The battery is out of warranty, and Chevrolet no longer provides replacement battery cells or battery replacement at an affordable price. In fact, they struggle to provide parts for this car, which has been out of production for some time. I will likely repair the battery myself.""

"A hall effect sensor attached to the outside of the hybrid electrical system coolant reservoir failed causing the vehicle to deny charging due to a safety lockout. Only a Chevrolet dealership has the appropriate General Motors software to correct this problem. Replacing the hall effect sensor alone did not fix the issue. The repair was over $500 which included a firmware update and replacing the sensor that cost less than $25 shipped. A technical service bulletin outlined all required steps which included flushing and pressure testing the coolant system and the dealership ignored it all. In my experience in general, dealerships and mechanics alike carry little empathy nor interest in vehicles with electric drive trains."
