The delayed recall left cars with potential safety problems on the road for years without GM warning drivers.
Documents show that General Motors recalled some Pontiac G6 midsize cars to fix a faulty brake light system in 2009, yet waited more than five years to call back over 2 million other cars with the same system.
GM recalled about 8,000 G6s from the 2005 and 2006 model years because the brake lights might not work when the driver stepped on the pedal, according to the documents. But it didn't recall newer G6s or the Chevrolet Malibu and Saturn Aura until three weeks ago. The cars are nearly identical.
The delayed recall left cars with potential safety problems on the road for years without GM warning drivers. GM says the problem occurred less frequently in those cars. GM says the problem has caused 13 accidents and 2 injuries.
