DETROIT (AP) — General Motors recalled a small number of 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, according to company documents filed with federal safety regulators.

The documents, filed Thursday, show that GM recalled about 8,000 Pontiacs from the 2005 and 2006 model years because the brake lights might not work when the driver stepped on the brake pedal. But the company didn’t recall later-model G6s or the Chevrolet Malibu and Saturn Aura until three weeks ago. The cars are nearly identical.
