We are more convinced than ever that the Volt didn’t cause the garage fire in Barkhamsted, Conn. Here’s why.
Our engineering experts investigated the scene of the fire and analyzed the Volt and its battery pack and charging equipment. After discussions with the local fire officials and the insurance investigators, our engineers are even more convinced that the fire did not originate with the Volt or in the vicinity where the Volt was charging.
Late yesterday, the fire marshal closed his investigation and has since turned it over to the insurance company and General Motors. We will continue investigating the Volt to determine if any other learnings are available from this incident.
We again extend our thoughts to the Connors family, who worked with GM and the fire marshal to gather necessary information for the investigation in the midst of their personal crisis. We’re happy they are safe and that’s what’s most important.
“My Volt was my very first new car purchase since 1963; I would like to get a second one," said homeowner Storm Connors.
Finally, we'd like to extend our thanks and appreciation to the Pleasant Valley Volunteer Fire Department and the investigators for their cooperation in this matter.”

Our engineering experts have inspected the Chevrolet Volt severely damaged in a garage fire in Barkhamsted, CT. We believe the findings indicate the Volt was damaged by the fire, not the cause.
The garage and its contents, including the Volt and a hand-built Suzuki Samurai EV, were heavily damaged in last Thursday's fire.
While the Volt's battery pack sustained damage, it was not extensive enough or of the type that would suggest that it caused the fire. In addition, there is clear evidence based on moderate damage to the cordset and charging system that neither component caused the fire.
The vehicles had been left in the garage for investigators and insurers to review when a second incident occurred earlier today. Smoke was seen coming from the damaged Volt and the fire department responded quickly. We continue to support the department in its investigation, sending our experts back to Connecticut to continue working with fire marshals.
We've spent more than a decade developing the technology which went into Volt. As such, it has a wide range of active and passive safety systems to ensure our customers are protected.
The most important thing to remember is that everyone is safe and fire investigators are working diligently to determine the cause. We'll share more information as it becomes available.

Original post:
A house fire in Barkhamsted, Connecticut early yesterday destroyed a garage and two electric cars, including a Chevrolet Volt and a hand-built Suzuki Samurai EV made by the home's owner. We're relieved to know that no one was hurt. The owner is an EV enthusiast who has been active in the alternative energy space for a number of years.
We've already contacted the customer to offer our support and spoken to a fire investigator to help wherever we can there as well.
It's completely understandable that all possible fire causes would be investigated. We stand behind the many active and passive safety systems in the Volt's design. We believe the owner's Volt has been a victim of this fire, not a cause.
Fire marshals haven't named any 'suspect' for the cause, so it's wrong to suggest they have. Of course, one tweet is another's truth, right? Anyone taking the idea of "can't rule out ..." to "might have" to "probably did" to statements of fact about what caused this fire should defer to the Connecticut fire investigation experts.
We take our customers' safety extremely seriously and the Chevrolet Volt has been built to meet all applicable US and international safety standards. To go a little deeper into detail, consider these aspects of Volt design:
- The Volt's charge cordset is certified and validated to rigorous short-circuit, overload, voltage surge, voltage dips and interruptions, ground fault and other requirements.
- The communication between the charge cordset and the vehicle charging system on the Volt meets SAE charging standards.
- At the vehicle level, the Volt has state-of-the-art monitoring and controls to detect and help ensure against malfunctions.
- Monitoring includes, among other things, AC and DC voltages; charge current; isolation of the high voltage from chassis ground; battery pack cell voltages and temperatures.
- If a malfunction that is potentially safety-related is detected, charging is immediately terminated and safeguards are invoked to isolate the high voltage system to the battery pack.
We'll continue to work with the Connecticut fire investigators, the owner and his family to determine what happened.
