According to recent reports, one million cars could be added to the General Motors brake light recall.

The reports show that the National Highway Traffic Safety Administration is investigating complaints linked to the 2007 through 2009 Saturn Aura and 2004 through 2011 Chevrolet Malibu. Consumers claim that the brake lights in these particular vehicles may not come on once the pedal is pressed. Reports also indicate that the light may also come on when the driver is not pressing the brake pedal.

In 2009, General Motors issued a recall for several Pontiac G6 vehicles due to the issue with the brake lights. The vehicles linked to the GM recall included all units of the 2005 G6, however, the federal agency stated that the 2005 through the 2009 models may also present the same issue. Due to this issue, the agency decided to initiate a probe into this matter, but since complaints linked to other models surfaced, the agency may have to also add the Malibu and Saturn Aura models to the probe.

These vehicles share multiple of the same parts with the G6. Information concerning the brake lights and if all potentially affected models share the same light system hasn’t been disclosed.

Over 1.5 millions of vehicles could be affected by this recall if the federal agency uncovers issues with the Malibus and Auras. Additional recalls linked to the first recall that affected 8,000 cars haven’t been issued so far.

The 2009 recall stated that the issue was linked to the corrosion in a wiring connector, which is a crucial part of the G6 vehicles. Dealers had the issue fixed by putting a lubricant on the connector, which would prevent the part from corroding and causing the lights to fail when the brake pedal is pressed. If issues are discovered with Malibu and Aura models, the company may have to issue a second recall announcement.

According to the National Highway Traffic Safety, vehicles with brake lights that fail to work properly could increase the risk of an accident since vehicles following behind may fail to notice the car ahead is slowing down. Some of the issues linked to the brake lights could also affect the cruise control, which could cause it to fail to engage or even disengage inadvertently.

Owners of potentially affected vehicles should report any brake light problems to Chevrolet, GMC, Buick or Cadillac, or contact the federal agency at once.
