DETROIT (AP) — A person briefed on the matter says General Motors will ask Volt owners to bring their electric cars into dealers to strengthen the structure around the batteries.
The move is similar to a recall and involves the 8,000 Volts sold in the U.S. in the past two years.
The move comes after three batteries caught fire after side-impact crash tests done by federal safety regulators. The fires occurred seven days to three weeks after the tests and have been blamed on a coolant leak that caused an electrical short. No fires have broken out in real-world crashes.
The person says GM will contact Volt owners and have them return the cars to dealers for several structural repairs.
The repairs are a step below a formal recall.
The person did not want to be identified because GM executives will announce the plan later Thursday.
