General Motors has issued a recall for 2010-2014 model-year Chevrolet Camaros. A driver’s knee can bump the key fob causing the key to inadvertently move out of the “run” position — resulting in a reduction or loss of power.

Primarily affecting drivers sitting close to the steering column, GM discovered this issue during internal testing following the ignition switch recall earlier this year, according to GM.

There are 464,712 Camaros in the U.S. included in this recall. Including Canada, Mexico and exports, the total number of recalls is 511,528.

“Discovering and acting on this issue quickly is an example of the new norm for product safety at GM,” said Jeff Boyer, vice president of GM Global Safety.

The Camaro ignition system meets all GM engineering specifications and is not related to the ignition system used in Chevrolet Cobalts and other small cars involved in the ignition switch recall.

GM is aware of three crashes that resulted in four minor injuries; it believes these crashes may be attributed to the key issue, says the company.

GM will change the Camaro key to a standard design where the key is concealed in the fob and can be opened by pushing a button. This change will create a separation of the ignition key from the fob, so the fob won’t move the key from the “run” position.

Rental fleets registered 8,833 Camaro vehicles in 2013, according to the 2014 Automotive Fleet Fact Book.
