In the wake of an NHSTA "formal safety investigation," GM today announced plans to add enhancements to the Chevy Volt's battery coolant system, in the hopes of preventing any post-crash electrical fires. As a result, some 8,000 Volt drivers will have to bring their cars back to their dealerships, as part of a move that's one notch below a formal recall. GM made the decision following federal investigation that saw three batteries erupt in flames after side-impact crash tests. Regulators blamed the irregularity on a coolant leak though thus far, no similar incidents have been reported among any Volt owners. The manufacturer plans to remedy the situation by adding extra support to protect the battery during side collisions, adding an extra sensor to keep an eye on coolant levels, and by incorporating an extra bracket atop the coolant reservoir to guard against potential overflows. Vehicles with these enhancements, GM said, passed the tests without any leakage or battery pack damage. Head past the break for the full PR.
Update: Chevrolet has just reached out to us to clarify that adding these enhancements is voluntary, and not mandatory for Volt owners: "These modifications are part of a voluntary customer satisfaction effort. While we will encourage customers to return to a dealership to have their Volt's modified, it is voluntary for them as well."
