PRESS RELEASE
General Motors is advising Volt owners to return their electric cars to dealers for repairs that will lower the risk of battery fires.
The company hopes that the repairs, which will add steel to the plates protecting the batteries, will ease worries about the car's safety. Three Volt batteries caught fire after government crash tests last year, prompting a federal investigation and sending GM engineers scrambling to find a fix.
The free repairs, announced Thursday, will fix 8,000 Volts on U.S. roads and another 4,400 still for sale. The cars are covered by a "customer service campaign" run by GM, which is similar to a safety recall but allows the carmaker to avoid the bad publicity and federal monitoring that come with a recall.
GM and federal safety officials believe last year's fires were caused by coolant leaking from damaged plastic casing around the batteries after side-impact collisions. That coolant caused an electrical short, which sparked battery fires seven days to three weeks after the crashes.
GM has a huge incentive to fix the problem and protect the Volt's image. Although the car isn't a big seller -- it's fallen short of sales goals -- it burnishes GM's image as a greener, more innovative carmaker.
The safety stumble could make it even harder for the Chevrolet Volt to compete with rival electric cars such as the Nissan Leaf. To contain the bad publicity after the fires, GM last year offered to buy back Volts from worried owners. Still, no owners have reported fires after crashes.
Starting in February, dealers will add steel to a plate that protects the Volt battery, spreading the force of a crash over a larger area, says Mary Barra, GM's product development chief. Tests by the GM and the government have shown that the repairs prevent battery damage and coolant leaks.
"We have made the Volt even safer," says Mark Reuss, GM's North American president.
GM has done crash tests on four reinforced Volts and found that the fix worked. The National Highway Traffic Safety Administration -- the federal safety agency -- has also crashed a Volt with the added steel. "The preliminary results of the crash test indicate the remedy proposed by General Motors today should address the issue," the agency says.
