Owners have filed 26 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Electrical accounts for 28% of all owner complaints filed against this vehicle, across 7 categories tracked.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
The 2014 Volt electrical complaints reveal persistent issues across multiple systems. Instrument cluster and infotainment failures are common—displays go dark at random, leaving drivers unable to see speed, fuel level, or battery status. One owner reported a cascade of false error messages (cluster errors, battery reading zero while full, fuel reading zero with half tank, units switching to metric on their own) that repeated continuously while driving at highway speeds. Another owner's head unit rebooted while driving shortly after a manufacturer recall repair.
Propulsion power loss occurs frequently, with owners reporting loss of acceleration, unexpected surging despite light brake pressure, and stalling when switching between electric and gas modes or when batteries deplete. A brand-new vehicle (66 miles on odometer) suffered "Engine Not Available" and "Propulsion Power Reduced" failures on the New Jersey Turnpike. Older vehicles with 100,000+ miles report similar issues; one owner experienced the problem almost daily by the time warranty expired.
Battery and charging problems disable vehicles unexpectedly. Multiple owners report charging interruption messages that appear despite proper charger connection and no actual user override. Batteries show zero range when full. Some vehicles fail to charge at all and become immobilized. Airbag sensors malfunction repeatedly, triggering persistent warning messages that dealers say cost over $600–$1,300 to fix but GM has not recalled.
The ignition power button sits dangerously close to the drive mode button, causing accidental engine shutoffs at highway speeds. Owners report having to use a complicated three-step restart procedure while rolling, which OnStar was unaware of. The Level 1 charging cable deteriorates, exposing wires and creating fire hazard. Overall, electrical gremlins left multiple owners stranded on highways and unable to diagnose problems themselves.

I bought my car and I had no idea about a known issue that this car has. Unsuspecting and trusting, I noticed my car had a reduced propulsion and it would like lose power and just slowly jerk and then really drastically reduce speed without anyway to fix it and on the freeway I got scared as I have never in my life has this happen in any car. So it happen a couple more times and I took a picture…
The electric heating system failed on my volt which disabled the windshield defroster, creating a dangerous visibility situation. The volt has two heating systems, the traditional waste heat from the engine's cooling system and an all-electric resistor pack. When the car runs in all-electric mode, the engine does not engage and the traditional heating system is ineffective. There is a mode…
Chevrolet volt 2014 head unit reboots while vehicle in motion (city streets and freeways). No user auxiliary device plugged in. Fh daily san leandro could not identify problem. Rebooting occured approximately 1 month ago after manufacturer recall repair. Car was last serviced 11/22/16 for stated problem. Head unit rebooted 12/1/16 while in motion on city street. Head unit provides vital…
Ignition shut off on massachusetts turnpike when trying to change from normal (electric) to hold (gas) mode. Mode button is too close to ignition power button. I had to stop in rush hour traffic to put car in drive and restart, could have been hit. I called onstar emergency service in the moment, but they were not aware of a way to restart the car while it was rolling. Discovered later that…
Common questions
How serious is the electrical problem on the 2014 Chevrolet Volt?
It's a meaningful issue. 26 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $850.
At what mileage does the electrical typically fail?
Across the 17 complaints that reported odometer mileage, most electrical failures cluster between 39,200 and 61,000 miles, with the median around 55,000. A quarter of owners report trouble before 39,200; a quarter make it past 61,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $850 for electrical repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to electrical?
No active recalls currently cover electrical issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
