General Motors (GM) has sent letters to the 1.4 million owners of 2003-2007 GM cars in the United States, saying that ignition kits have been shipped to 4,300 dealers as part of its latest recall.

The company said in a press release that the owners may set an appointment with their GM dealer to have the faulty ignition switch replaced, a job that would take around 90 minutes, depending on the dealership.

GM also said that the nearly 800,000 owners of 2008-2011 GM cars will receive a letter confirming their inclusion in the recall. The carmaker will also send another letter on when the parts will be available.

The company left guidelines for owners who haven’t availed the recall, such as removing the key ring, putting the car in reverse gear with the parking brake on for manual-transmission cars and putting the car in ‘Park’ for automatic-transmission cars before removing the key.

The ignition switches were recalled on March 2014 because these could unintentionally move from the ‘run’ position to the ‘accessory’ or ‘off’ position, which could make the vehicle lose power and disable the safety features.

The defect affects nearly 2.2 million cars produced from 2003-2011, including:

  • 2003-2007 Saturn Ion
  • 2005-2010 Chevrolet Cobalt
  • 2006-2010 Pontiac Solstice
  • 2007-2010 Pontiac G5
  • 2007-2010 Saturn Sky
  • 2006-2011 Chevrolet HHR

The fault has already killed 13 people, which led to suspension (with pay) of two senior GM engineers.
