General Motors has announced it will expand the use of a brake override system to all eligible cars, just as the National Highway Traffic Safety Administration (NHTSA) has reportedly opened an investigation into brake issues on GM products that could see a recall of up to 6.2 million vehicles.

The "enhanced smart pedal" technology will be installed on all GM vehicles with an automatic transmission and electronic throttle control by 2012 says GM. The software will allow the brakes to override the throttle if both pedals are pressed simultaneously.

As for the possible recall, NHTSA said it is looking into a situation of brake line corrosion on 6 million GM pickups and SUVs made from 1999-2003 and 189,000 2500 heavy-duty pickups made in 2003. The NHTSA says it has received 110 complaints and allegations of three crashes relating to the loss of braking power due to corroded brake lines.

Toyota recently announced the expansion of a brake override system to all of its vehicles after it recalled million of vehicles due to sticking brake pedals.
